本文详细记录了在CentOS8系统上搭建基于Swoole4的Laravel8应用，并配置Nginx进行转发的全过程。涵盖了Swoole的安装、配置，Laravel的安装与环境配置，以及Nginx的配置，包括负载均衡和与Swoole的通信。此外，还介绍了如何解决在搭建过程中遇到的问题，如php_json_exception_ce的加载问题。

CentOS8搭建Web服务器笔记2 Swoole4+Laravel8+LaravelS3

1. Swoole PHP 协程框架

Swoole 使 PHP 开发人员可以编写高性能高并发的 TCP、UDP、Unix Socket、HTTP、 WebSocket 等服务，让 PHP 不再局限于 Web 领域。

1.1 查询最新发布版本

https://github.com/swoole/swoole-src/releases
在这里插入图片描述

1.2 下载源码包

https://github.com/swoole/swoole-src/archive/v4.6.3.tar.gz

[root@VM-0-16-centos downloads]# wget -O swoole4.6.3.tar.gz https://github.com/swoole/swoole-src/archive/v4.6.3.tar.gz 
[root@VM-0-16-centos downloads]# ls
php-8.0.2  php-8.0.2.tar.gz  nginx-1.19.7  nginx-1.19.7.tar.gz  swoole4.6.3.tar.gz
  • 解压安装文件到downloads目录
    tar -zxvf /usr/local/downloads/swoole4.6.3.tar.gz -C /usr/local/downloads
[root@VM-0-16-centos downloads]# tar -zxvf /usr/local/downloads/swoole4.6.3.tar.gz -C /usr/local/downloads

1.3 安装依赖

yum install libcurl-devel glibc-headers gcc-c++ pcre-devel
yum install automake autoconf bison

1.4 编译安装

  • 用phpize生成configure
[root@VM-0-16-centos downloads]# cd /usr/local/downloads/swoole-src-4.6.3
[root@VM-0-16-centos swoole-src-4.6.3]# ls
clear.sh        CODE-STYLE.md  examples          include        mascot.png    src           tools
CMakeLists.txt  config.m4      ext-src           LICENSE        package.xml   SUPPORTED.md  travis
code_format.sh  CPPLINT.cfg    gdbinit           Makefile.frag  README-CN.md  tests
code_stats.sh   CREDITS        google-style.xml  make.sh        README.md     thirdparty

存在configure文件就跳过，没有就用phpize生成configure

  • 未安装php-devel运行phpize时报错
[root@VM-0-16-centos swoole-src-4.6.3] phpize
Can't find PHP headers in /usr/include/php
The php-devel package is required for use of this command.
  • 查询php版本并安装相应的php-devel
    yum -y install php-devel
[root@VM-0-16-centos swoole-src-4.6.3]# php -v

  • 配置参数

[root@VM-0-16-centos swoole-src-4.6.3]# ./configure  \
 --enable-openssl  \
--enable-swoole-json  \
--enable-swoole-curl

参数详情参考官方说明
https://wiki.swoole.com/#/environment?id=%e7%bc%96%e8%af%91%e9%80%89%e9%a1%b9

  • 编译安装
    make && make install
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/downloads/swoole-src-4.6.3/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /usr/local/php8/lib/php/extensions/no-debug-non-zts-20200930/
Installing header files:          /usr/local/php8/include/php/

查看安装的扩展文件

[root@VM-0-16-centos swoole-src-4.6.3]# cd /usr/local/php8/lib/php/extensions/no-debug-non-zts-20200930/
[root@VM-0-16-centos no-debug-non-zts-20200930]# ls
mysqli.so  opcache.so  pdo_mysql.so  swoole.so

1.5 配置php启用swoole扩展

1.5.1 查看 php.ini 位置

php -i | grep php.ini

[root@VM-0-16-centos ~]# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php8/etc
Loaded Configuration File => /usr/local/php8/etc/php.ini

1.5.1 配置php扩展

vi /usr/local/php8/etc/php.ini

Dynamic Extensions 配置项中加入extension=swoole.so

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename
;
; For example:
;
;   extension=mysqli
;
; When the extension library to load is not located in the default extension
; directory, You may specify an absolute path to the library file:
;
;   extension=/path/to/extension/mysqli.so
;
; Note : The syntax used in previous PHP versions ('extension=<ext>.so' and
; 'extension='php_<ext>.dll') is supported for legacy reasons and may be
; deprecated in a future PHP major version. So, when it is possible, please
; move to the new ('extension=<ext>) syntax.
;
; Notes for Windows environments :
;
; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
;   extension folders as well as the separate PECL DLL download (PHP 5+).
;   Be sure to appropriately set the extension_dir directive.
extension=swoole.so

1.5.3 查看php加载swoole扩展情况

  • 重启fpm
    systemctl restart php-fpm
  • 命令行查看swoole加载情况
    php -m | grep swoole
[root@VM-0-16-centos ~]# php -m | grep swoole
swoole

php已经成功加载swoole扩展

  • phpinfo页面查看swoole加载情况
    在这里插入图片描述

1.5.4 加载报错处理

1.5.4.1 undefined symbol: php_json_exception_ce
[root@VM-0-16-centos ~]# php -m | grep swoole
PHP Warning:  PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/lib64/php/modules/swoole.so (/usr/lib64/php/modules/swoole.so: undefined symbol: php_json_exception_ce), /usr/lib64/php/modules/swoole.so.so (/usr/lib64/php/modules/swoole.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

报错是由swoole.so模块发出，说明swoole已经加载中，需要先加载php_json

  • 查看/etc/php.d目录的ini文件
[root@VM-0-16-centos ~]# ls /etc/php.d
10-opcache.ini   20-exif.ini      20-json.ini       20-sockets.ini    30-mysqli.ini
20-bz2.ini       20-fileinfo.ini  20-mbstring.ini   20-sqlite3.ini    30-pdo_mysql.ini
20-calendar.ini  20-ftp.ini       20-mysqlnd.ini    20-tokenizer.ini  30-pdo_sqlite.ini
20-ctype.ini     20-gd.ini        20-pdo.ini        20-xml.ini        30-xmlreader.ini
20-curl.ini      20-gettext.ini   20-phar.ini       20-xmlwriter.ini  opcache-default.blacklist
20-dom.ini       20-iconv.ini     20-simplexml.ini  20-xsl.ini
[root@VM-0-16-centos ~]# cat 20-json.ini
; Enable json extension module
extension=json

PHP默认加载的扩展配置不是在 /etc/php.ini 中，而是在 /etc/php.d/ 这个目录，当中的 .ini 文件是在 /etc/php.ini 加载完成后再加载的，所以extension=swoole.so 写在 /etc/php.ini 的Dynamic Extensions中，就是先加载了 swoole.so 再加载 json，导致了 swoole 找不到 php_json_exception_ce情况发生 。

  • 去掉/etc/php.ini的extension=swoole.so
    vim /etc/php.ini

#extension=swoole.so

  • 在/etc/php.d/目录创建40-swoole.ini
    vim 40-swoole.ini
extension=swoole

这里文件swoole.ini加入40-前缀，是为了让它最后加载，让数字小的先加载。

[root@VM-0-16-centos ~]# cd   /etc/php.d/
[root@VM-0-16-centos ~]# ll
10-opcache.ini   20-exif.ini      20-json.ini       20-sockets.ini    30-mysqli.ini

20-dom.ini       20-iconv.ini     20-simplexml.ini  20-xsl.ini        
[root@VM-0-16-centos ~]# vim 40-swoole.ini
extension=swoole

:wq保存退出

[root@VM-0-16-centos ~]# ll

  • 重启fpm，查看swoole加载情况
    systemctl restart php-fpm
  • 命令行查看swoole加载情况
    php -m | grep swoole
[root@VM-0-16-centos ~]# systemctl restart php-fpm
[root@VM-0-16-centos ~]# php -m | grep swoole
swoole

1.6 配置Nginx转发Swoole

1.6.1 Nginx与Swoole通信模式

[root@VM-0-16-centos ~]# find /etc/nginx/conf.d -name *.conf
/etc/nginx/conf.d/default.conf
/etc/nginx/conf.d/php-fpm.conf
  • default.conf
    默认站点配置文件
  • php-fpm.conf
    php-fpm的负载分发upstream模块配置文件
[root@VM-0-16-centos ~]# vi /etc/nginx/conf.d/default.conf

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
    location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   unix:/dev/shm/php-fpm.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

nginx遇到需要php处理的请求都会转发给php-fpm处理

  • IP通信+网关代理
    fastcgi_pass 127.0.0.1:9000;
  • unix sock通信+网关代理
    fastcgi_pass unix:/run/php-fpm/www.sock
    推荐把sock放在内存提高访问效率
    fastcgi_pass unix:/dev/shm/www.sock
  • upstream负载均衡+反向代理
    upstream_name ：自定义upstream名称
    proxy_pass http://upstream_name;

1.6.2 Nginx负载均衡模块 upstream

upstream模块，使nginx跨越单机的运算限制，分发给不同主机处理php业务，实现网络数据的接收、处理和转发。

1.6.2.1 FPM upstream模块配置

FPM是php系统自带的处理模块，我们看下它的upstream默认配置。
cat /etc/nginx/conf.d/php-fpm.conf

# PHP-FPM FastCGI server
# network or unix domain socket configuration
# sock
upstream php-fpm {
        server unix:/run/php-fpm/www.sock;
}
# TCPIP
upstream php-fpm-tcp {
        server  127.0.0.1:9000 weight=3 max_conns=2000;
		server  127.0.0.2:9000 weight=2 max_conns=2000 down;
		#server  127.0.0.3:9000 backup max_conns=1000;
}
1.6.2.2 swoole upstream模块配置

新建conf配置swoole的upstream，让nginx把php请求发送给swoole处理。
vim /etc/nginx/conf.d/swoole_http.conf

# 这是swoole的负载分发配置
upstream swoole_http{
	#ip_hash;
	server  127.0.0.1:9501 weight=3 max_conns=2000;
	server  127.0.0.2:9501 weight=2 max_conns=2000 down;

1.6.2.3 upstream 模块参数解析
  • 负载均衡分配方式
  • 轮询 默认
    每个请求按顺序分配到不同后端服务器
  • ip_hash
    哈希表分配负载，根据散列算法分配不同用户固定访问一个后端服务器，相同的客户端ip请求相同的服务器，解决session一致问题
    有条件架构独立Redis服务器，缓存所有后端服务器的session，也能解决session一致问题
  • weight
    权重数值越大，负载分配几率越大
    不设权重，默认把请求轮循负载到各个服务器

轮询，ip_hash，权重三种分配方式不能同时生效，三选一

  • 参数解析
  • max_conns
    最大连接数
    限制服务器允许的最大连接数量，超过的连接不会分配，轮询分配到其他服务器。默认为0为不限制。
  • backup
    后备服务器
    只有其他所有swoole服务器都负载饱和或当机才被启用加与负载
  • down
    当机标记
    有服务器当机，nginx自动标记服务器，排除down服务器的负载分配
  • max_fails 单位时间内重试连接次数
  • fail_timeout 允许重试连接的单位时间和请求失败等待轮询的单位时间
    在单位周期fail_timeout内，重试连接达到max_fails次数，nginx把此服务器节点标记为宕机不可用（down），将连接转到其他服务器节点；
    有新的连接符合下一个周期（单位时间为fail_timeout）再一次去请求，判断是否连接是否成功，恢复此节点。

1.6.3 Nginx 转发 PHP请求

1.6.3.1 FMP 的php请求转发
    # php-fpm 管理模式处理php请求配置
	location ~ \.php$ {
        #网关代理转发请求到unix sock
        #fastcgi_pass   unix:/dev/shm/php-fpm.sock;
        #网关代理转发请求到TCPIP
        fastcgi_pass   127.0.0.1:9000;
        #网关代理转发请求到upstream
        #fastcgi_pass	php-fpm
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

正则匹配所有对.php文件的请求，由fastcgi管理程序转发给fpm-php进程处理

正则表达式匹配

  • = 精确匹配；
  • ^~ 提高前缀字符串的匹配优先级；
  • ~ 区分大小写的正则表达式匹配；
  • ~* 不区分大小写的正则表达式匹配；
  • / 通用匹配（因为所有的地址都以 / 开头，所以这条规则将匹配到所有请求），如果没有其它匹配，任何请求都会匹配到。

匹配优先级
( = ) >（ ^~ ) > ( ~) > ( ~* ) > ( / ) > ( 长字符串 ) > ( 短字符串 )

1.6.3.2 Swoole 的php请求转发配置
  • 只转发php请求给Swoole
    # swoole 框架处理php请求配置
    location ~ \.php$ {
        proxy_http_version 1.1;
        proxy_set_header Connection "keep-alive";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        # 反向代理转发请求到upstream节点
        proxy_pass http://swoole_http; 
        # 反向代理转发请求到TCPIP
		#proxy_pass http://127.0.0.1:9501;
    }
  • 转发所有请求给Swoole

配置1

	# swoole 框架处理所有请求配置
	location / {
    	proxy_http_version 1.1;
        proxy_set_header Connection "keep-alive";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        if (!-e $request_filename) {
        	# 反向代理转发请求到upstream节点
        	proxy_pass http://swoole_http;
        	# 反向代理转发请求到TCPIP
			#proxy_pass http://127.0.0.1:9501;
        }
    }

配置2

	location / {
        # $uri文件存在,Nginx处理,否则交给Swoole处理
        try_files $uri @swoole;
    }
    location @swoole {
        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Connection "keep-alive";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
    }

设置/home为项目父目录

[root@VM-0-16-centos downloads]# cd /home

2.3.2 使用Laravel安装器创建项目

在当前目录下创建myapp项目
laravel new myapp

[root@VM-0-16-centos home]# laravel new myapp

2.3.3 使用Composer管理器创建项目

2.3.3.1 当前目录下创建myweb项目
  • 当前目录下创建myweb项目
    composer create-project laravel/laravel myweb
  • 指定目录下创建myweb项目
    composer create-project laravel/laravel --prefer-dist /home/web/myweb

composer create-project laravel/laravel[=版本号] --prefer-dist [路径]

  • 版本号
    创建指定版本的laravel项目
  • 路径
    未指定路径时，在当前命令行所在目录下，创建名为laravel项目目录
    指定路径时，路径目录应是空目录，不能有其他文件存在，laravel项目文件会生成到路径目录里

指定安装包来源

  • 国外来源
    composer config -g repo.packagist composer https://packagist.org
  • 国内镜像
    composer config -g repo.packagist composer https://packagist.phpcomposer.com
[root@VM-0-16-centos downloads]# cd /home
[root@VM-0-16-centos home]# composer create-project laravel/laravel myweb --prefer-dist

2.3.3.3 设置storage目录权限

此步骤是必要条件！storage目录没有写权限会报错

chmod -R 777 /home/myweb/storage

2.3.4 解决问题

2.3.4.1 问题 require ext-fileinfo *
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/framework[v8.12.0, ..., 8.x-dev] require league/flysystem ^1.1 -> satisfiable by league/flysystem[1.1.0, ..., 1.x-dev].
    - league/flysystem[1.1.0, ..., 1.x-dev] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
    - Root composer.json requires laravel/framework ^8.12 -> satisfiable by laravel/framework[v8.12.0, ..., 8.x-dev].

To enable extensions, verify that they are enabled in your .ini files:
    - /usr/local/php8/etc/php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
  • 编译安装fileinfo扩展
[root@VM-0-16-centos home]# find / -name fileinfo
/usr/local/downloads/php-8.0.2/ext/fileinfo
[root@VM-0-16-centos home]# cd /usr/local/downloads/php-8.0.2/ext/fileinfo
[root@VM-0-16-centos fileinfo]# ls

[root@VM-0-16-centos fileinfo]# phpize && ./configure --with-php-config=/usr/local/php8/bin/php-config
[root@VM-0-16-centos fileinfo]# make && make install
  • 编辑php.ini启用fileinfo扩展
    vim /usr/local/php8/etc/php.ini
extension=fileinfo
2.3.4.2 问题 to retrieve a token. Token (hidden):
  • GitHub注册获取Token
  • https://github.com/settings/tokens
  • 登录或注册GitHub帐号
  • Personal Access Tokens页面点击Generate new token
  • Note 里面填写自定义令牌名称
  • 点击Generate token生成token
  • 复制token码
  • 设置composer全局token
    composer config --global github-oauth.github.com <token>
[root@VM-0-16-centos home]# composer config --global github-oauth.github.com abcdefghijk1234567

2.5 Laravel访问数据库配置

2.5.1 数据库访问配置

2.5.1.1 Mysql连接配置

Laravel提供了自定义连接配置，可以给不同的多个用户，分别连接访问不同的数据库，也可以让多用户拥有不同权限访问同一数据库。

  • ‘mysql’ => [ 数据库连接配置名称
    连接配置名称可以自定义
  • env(‘DB_HOST’, ‘127.0.0.1’) 环境变量取值
    env(‘变量名’,‘预设值’)
    从.env文件中取回相应变量DB_HOST的值，如果.env没有定义由预设值127.0.0.1代替，其他以此类推。
  • strict 严格模式
    MySQL在处理数据更改命令时，严格检测语句中的无效值或缺失值。
    如insert或update操作时，错误的列类型，或超出范围的数据值。

            'database' => env('REDIS_DB', 0),
        ],
        'cache' => [//Redis连接配置名称
            'url' => env('REDIS_URL_CACHE'),
            'host' => env('REDIS_HOST_CACHE', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD_CACHE', null),

            'database' => env('REDIS_DB_CACHE', 1),
        ],
        'h5app' => [//Redis连接配置名称
            'url' => env('REDIS_URL_H5'),

            'password' => env('REDIS_PASSWORD_H5', null),
            'port' => env('REDIS_PORT_H5', 6379),
            'database' => env('REDIS_DB_H5', 10),
        ],
    ],
  • 分别设置了三组连接配置
    default 站点访问的公共数据
    cache 用户个人信息临时缓存
    h5 独立站点使用的redis数据缓存
  • 连接配置名称和环境变量的名称，都可以根据功能需求自定义的，只要连接配置和环境变量能对应上就行，如h5app配置里的host变量就自定义REDIS_HOST_H5
  • ‘database’ => env(‘REDIS_DB’, 0)
    默认redis服务器会创建16个数据库，数据库是由一个整数索引标识0-15，而不是由一个数据库名称。默认情况下，一个客户端连接到数据库0，env(‘REDIS_DB’, 0)中的预设值就不要加引号了。
  • redis 多库环境配置
REDIS_HOST=localhost
REDIS_DB=0
REDIS_PASSWORD=123456
REDIS_PORT=6379
REDIS_PREFIX=prj_

REDIS_HOST_CACHE=localhost
REDIS_DB_CACHE=1
REDIS_PASSWORD_CACHE=123456
REDIS_PORT_CACHE=6379

REDIS_HOST_H5=localhost
REDIS_DB_CACHE=2
REDIS_PASSWORD_H5=123456
REDIS_PORT_H5=6379

上面三组环境变量如果host分别指向不同的地址，结果对应访问三台不同的redis数据服务器的0，1，2三个数据库；
如果host指向同一地址，结果是访问同一redis数据服务器的0，1，2三个数据库；

3.3 注册服务模块

Laravel 5.5+ 以上版本跳过此步骤，安装器自动寻找项目目录下composer.json注册。

修改Laravel工程根目录下config/app.php文件

'providers' => [
    //...
    Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class,
],

3.4 发布laravelS配置

LaravelS 每次升级，都需重新发布配置到项目中
php artisan laravels publish

3.5 Laravel 和 LaravelS配置项

3.5.1 Laravel 环境变量 ( Laravel框架配置 )

（注意此处是Laravel框架配置，不是LaravelS扩展包配置）

进入Laravel 工程根目录下.env
vim /home/myweb/.env

LARAVELS_LISTEN_IP=localhost
LARAVELS_DAEMONIZE=true
LARAVELS_WORKER_NUM=16
  • LARAVELS_LISTEN_IP
    LaravelS 监听地址
    如果config/laravels.php中socket_type为SWOOLE_UNIX_STREAM
    监听改为socket文件路径，如
    LARAVELS_LISTEN_IP=unix:/dev/shm/laravels.sock
  • LARAVELS_DAEMONIZE
    后台方式运行LaravelS服务
  • LARAVELS_WORKER_NUM
    最大php工作子进程，每个进程大概40M的内存，计算方法可有参考《PHP-FPM进程数与内存调优》

3.5.2 LaravelS 配置文件( LaravelS扩展包配置 )

  • （注意此处是LaravelS扩展包配置）

Laravel工程根目录下config/laravels.php文件
vim /home/myweb/config/laravels.php

  • 监听配置
'listen_ip' => env('LARAVELS_LISTEN_IP', '127.0.0.1'),
'listen_port' => env('LARAVELS_LISTEN_PORT', 5200),
'socket_type' => defined('SWOOLE_SOCK_TCP') ? SWOOLE_SOCK_TCP : 1,

listen_ip 监听地址
设置默认地址127.0.0.1
env(‘LARAVELS_LISTEN_IP’, ‘127.0.0.1’)， 优先读取判断Laravel的.env中是否设置了监听地址，如果没有使用这里设置的127.0.0.1地址

  • IPv4:
    “127.0.0.1” 监听本地地址
    “0.0.0.0” 监听所有地址
  • IPv6:
    "::1"监听本地地址
    "::"监听所有地址

listen_port 监听端口
设置默认端口5200
env(‘LARAVELS_LISTEN_PORT’, 5200)，优先读取判断Laravel的.env中是否设置了监听地址，如果没有使用这里设置的127.0.0.1地址

socket_type 套接字类型
如果使用SOCK_UNIX_STREAM类型，监听设置为socket文件路径，如
unix:/dev/shm/laravels.sock

  • SWOOLE_SOCK_TCP: TCP
  • SWOOLE_SOCK_TCP6: TCP IPv6
  • SWOOLE_SOCK_UDP: UDP
  • SWOOLE_SOCK_UDP6: UDP IPv6
  • SWOOLE_UNIX_DGRAM: Unix socket dgram
  • SWOOLE_UNIX_STREAM: Unix socket stream
  • Enable SSL: $sock_type | SWOOLE_SSL.
  • swoole 配置
'swoole' => [
        'daemonize'          => env('LARAVELS_DAEMONIZE', false),
        'dispatch_mode'      => 2,
        'reactor_num'        => env('LARAVELS_REACTOR_NUM', function_exists('swoole_cpu_num') ? swoole_cpu_num() : 8),
        'worker_num'         => env('LARAVELS_WORKER_NUM', function_exists('swoole_cpu_num') ? swoole_cpu_num() : 8),
        //'task_worker_num'    => env('LARAVELS_TASK_WORKER_NUM', function_exists('swoole_cpu_num') ? swoole_cpu_num() * 2 : 8),
        'task_ipc_mode'      => 1,
        'task_max_request'   => env('LARAVELS_TASK_MAX_REQUEST', 100000),
        'task_tmpdir'        => @is_writable('/dev/shm/') ? '/dev/shm' : '/tmp',
        'max_request'        => env('LARAVELS_MAX_REQUEST', 100000),
        'open_tcp_nodelay'   => true,
        'pid_file'           => storage_path('laravels.pid'),
        'log_level'          => 4,
        'log_file'           => storage_path(sprintf('logs/swoole-%s.log', date('Y-m'))),
        'document_root'      => base_path('public'),
        'buffer_output_size' => 2 * 1024 * 1024,
        'socket_buffer_size' => 8 * 1024 * 1024,
        'package_max_length' => 4 * 1024 * 1024,
        'reload_async'       => true,
        'max_wait_time'      => 60,
        'enable_reuse_port'  => true,
        'enable_coroutine'   => false,
        'upload_tmp_dir'     => @is_writable('/dev/shm/') ? '/dev/shm' : '/tmp',
        'http_compression'   => false,
    ],

  • daemonize 守护进程
    设置 true 时，程序将转入后台作为守护进程长时间运行。
    如果不启用守护进程，当 ssh 终端退出后，程序将被终止运行。

  • 更多swoole参数设置参考 https://wiki.swoole.com/#/server/setting

3.6 配置nginx启用LaravelS

  • 复制nginx配置
[root@VM-0-16-centos myweb]# cd /etc/nginx/conf.d
[root@VM-0-16-centos conf.d]# cp default.conf www.conf
[root@VM-0-16-centos conf.d]# ls
default.conf  www.conf
  • 配置laravelS的upstream模块
    vim /etc/nginx/conf.d/laravelS.conf
# 这是laravelS的负载均衡分发配置
upstream laravelS{
    server 127.0.0.1:5200 weight=5 max_fails=3 fail_timeout=30s;
    #server localhost:5200 weight=5 max_fails=3 fail_timeout=30s;
    #server unix:/dev/shm/laravels.sock weight=5 max_fails=3 fail_timeout=30s;
    keepalive 16;
}
  • 配置主页服务器
    vi /etc/nginx/conf.d/www.conf
# www服务器
server
{
        # 监听端口
        listen       80;
        # 服务器域名
        server_name localhost;
        # 指定首页文件

        }
        # 去除index action
        if ($request_uri ~* index/?$)
        {
