yum -y install gmp-devel
configure: error: Please reinstall readline - I cannot find readline.h
yum -y install readline-devel
当你看到这个 说明编译成功
make && make install
vi /etc/profile追加：PATH=$PATH:/usr/local/php/bin
更新：source /etc/profile
php -v
然后执行下图一系列操作
php -m 查看扩展 php --ini 查看php.ini配置文件位置
配置php.ini 文件
; 不显示错误，默认
display_errors = Off
; 在关闭display_errors后开启PHP错误日志（路径在php-fpm.conf中配置），默认
log_errors = On
; 字符集，默认
default_charset = "UTF-8"
; 文件上传大小，默认值太小，建议修改8M
upload_max_filesize = 2M
; Maximum size of POST data that PHP will accept. 表单最大值，默认是8M，如果表单含有多图上传，大小可能不够。超过该大小后台收不到 表单数据
post_max_size = 8M
; 设置PHP的扩展库路径，默认被注释了，之后一个文件夹 于 你/usr/local/php/lib/php/extensions/ 下的文件夹同名。
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/"
; 设置PHP的时区
date.timezone = PRC
; 开启opcache，默认是0
[opcache]
; Determines if Zend OPCache is enabled
opcache.enable=1配置php-fpm.conf 文件
; 去掉里分号，方便以后重启。建议修改
; Default Value: none
; 下面的值最终目录是/usr/local/php/var/run/php-fpm.pid
; 开启后可以平滑重启php-fpm
pid = run/php-fpm.pid
; 设置错误日志的路径，可以默认值
; Note: the default prefix is /usr/local/php/var
; Default Value: log/php-fpm.log, 即/usr/local/php/var/log/php-fpm.log
error_log = /var/log/php-fpm/error.log
; Log等级，可以默认值
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
log_level = notice
; 后台运行，默认yes，可以默认值
; Default Value: yes
; daemonize = yes
; 引入www.conf文件中的配置，可以默认值
include=/usr/local/php/etc/php-fpm.d/*.conf配置 www.conf 配置文件
; 设置用户和用户组，默认都是nobody。可以默认值
user = nginx
group = nginx
; 设置PHP监听
; 下面是默认值，不建议使用。可以默认值
listen = 127.0.0.1:9000
; 根据nginx.conf中的配置fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
;listen = /var/run/php-fpm/php-fpm.sock
######开启慢日志。可以默认值
slowlog = /var/log/php-fpm/$pool-slow.log
request_slowlog_timeout = 10sphp-fpm 检测 启动 关闭 重启
检测php-fpm配置文件：/etc/init.d/php-fpm -t
启动： /etc/init.d/php-fpm
kill -INT `cat /home/phpstudy/php/var/run/php-fpm.pid` # php-fpm关闭
kill -USR2 `cat /home/phpstudy/php/var/run/php-fpm.pid` #php-fpm平滑重启
二 nginx 安装
安装pcre
获取pcre编译安装包，在http://www.pcre.org/上可以获取当前最新的版本
[root@localhost src]# wget ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz解压pcre-8.42.tar.gz到/usr/local/
[root@localhost src]# tar xvf pcre-8.42.tar.gz -C /usr/local/进入解压缩目录，执行./configure
[root@localhost pcre-8.42]# ./configure编译 安装
make && make install
下载nginx源码包 ： wget http://nginx.org/download/nginx-1.16.1.tar.gz
解压 进入目录检测编译
./configure --prefix=/home/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/pcre-8.42/
make && make install
查看版本 /home/nginx/sbin/nginx -v
配置nginx.conf 文件
location / {
root /home/www/;
index index.html index.htm index.php;
if (!-e $request_filename) {
rewrite ^/index.php(.*)$ /index.php?s=$1 last;
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
location ~ \.php$ {
root /home/www/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
nginx -t 检测
./sbin/nginx 启动
nginx -s reload 重启
三 配置三台服务器nginx负载均衡
方式一
三台服务器都安装nginx 转发
user nginx;
worker_processes auto;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
events {
use epoll;
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
gzip on;
upstream amok_http {
server 127.0.0.1:81 weight=1;
server 192.168.255.134 weight=1;
server 192.168.255.135 weight=1;
}
#负载均衡请求分发
server {
listen 80;
#多域名用空格隔开
server_name www.2amok.com;
#设置默认访问首页
index index.html index.php;
location / {
#所有请求反向代理到服务器池中的服务器
proxy_pass http://amok_http;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
server {
listen 81;
server_name www.2amok.com;
charset utf-8;
#access_log logs/host.access.log main;
location / {
root /home/www/;
index index.html index.htm index.php;
if (!-e $request_filename) {
rewrite ^/index.php(.*)$ /index.php?s=$1 last;
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /home/www/;
fastcgi_pass 127.0.0.1:9000;
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;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
方式二 直接转发到 本机以及其它两台服务器 php-fpm 9000 端口
使用方式二 其它两台服务器不需要安装nginx 但是 php-fpm 监听端口必须改成 0.0.0.0:9000 修改文件是www.conf
user nginx;
worker_processes auto;
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
events {
use epoll;
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
gzip on;
upstream amok_http {
server 127.0.0.1:9000 weight=1;
server 192.168.255.134:9000 weight=1;
server 192.168.255.135:9000 weight=1;
}
server {
listen 80;
server_name www.2amok.com;

#access_log logs/host.access.log main;
location / {

index index.html index.htm index.php;
if (!-e $request_filename) {
rewrite ^/index.php(.*)$ /index.php?s=$1 last;
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /home/www/;
fastcgi_pass amok_http;
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

#}
}
ab 压测了下 两种方式，结果基本相同。 100人 1000 次 3000QPS左右 200人 3000次 2000QPS左右
