LNMP架构介绍
和LAMP唯一不同的是,LNMP中的N指的是Nginx(类似于Apache的一种web服务软件)。目前这种环境的应用也非常多。Nginx设计的初衷是提供一种快速、高效、多并发的Web服务软件。在静态页面的处理上,Nginx较Apache更胜一筹,但在动态页面的处理上,Nginx并不比Apache有优势。但是目前还是有很多爱好者对Nginx比较热衷。随着Nginx技术的不断成熟,它在Web服务软件领域的地位也会越来越高。
并且php是作为一个独立服务存在的,这个服务叫做php-fpm。Nginx直接处理静态请求,动态请求会转发给php-fpm。
MySQL安装
1. 删除之前安装的mysql
[root@xuexi-001 ~]# ps aux | grep mysql
root 1432 0.0 0.0 112720 972 pts/0 R+ 22:46 0:00 grep --color=automysql
[root@xuexi-001 ~]# rm -rf /usr/local/mysql
[root@xuexi-001 ~]# rm -rf /etc/init.d/mysqld
2.安装mysql过程
[root@xuexi-001 ~]# cd /usr/local/src/
[root@xuexi-001 ~]# wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz
[root@xuexi-001 ~]# cd /usr/local/src/
[root@xuexi-001 src]# tar zxvf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz
[root@xuexi-001 src]# mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql
[root@xuexi-001 src]# ls /usr/local/mysql/
bin data include man README share support-files
COPYING docs lib mysql-test scripts sql-bench
[root@xuexi-001 src]# ls /data/
mariadb mysql wwwroot
// 由于之前创建过,需要将其删除
[root@xuexi-001 src]# rm -rf /data/mysql/*
[root@xuexi-001 src]# useradd mysql
[root@xuexi-001 mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql/
[root@xuexi-001 mysql]# echo $?
0
[root@xuexi-001 mysql]# cp support-files/my-default.cnf /etc/my.cnf
[root@xuexi-001 mysql]# vim /etc/my.cnf
//定义内容如下:
basedir=/usr/local/mysql
datadir=/data/mysql
[root@xuexi-001 mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@xuexi-001 mysql]# vi /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql
[root@xuexi-001 mysql]# chmod 755 /etc/init.d/mysqld
[root@xuexi-001 mysql]# chkconfig --add mysqld
[root@xuexi-001 mysql]# chkconfig --list
[root@xuexi-001 mysql]# /etc/init.d/mysqld start

SUCCESS!
[root@xuexi-001 mysql]# ps aux |grep mysql

PHP安装
Nginx的PHP安装和上一章的PHP安装是有区别的,因为Nginx中的PHP是以fastcgi的方式给合Nginx的,可以理解为Nginx代理了PHP的fastcgi,而httpd是把PHP作为自己的模块来调用的。
1. 因为之前安装过php,这次重新安装的话直接在源码包目录下执行命令:make clean,删除之前编译过的文件内容,回到之前的解压的状态。

[root@xuexi-001 php-5.6.36]# make clean
find . -name \*.gcno -o -name \*.gcda | xargs rm -f
find . -name \*.lo -o -name \*.o | xargs rm -f

find . -name \*.so | xargs rm -f
find . -name .libs -a -type d|xargs rm -rf
rm -f libphp5.la sapi/cli/php sapi/cgi/php-cgi libphp5.la modules/* libs/*
2.创建账号
该账号用来运行php-fpm服务的,在LNMP环境中,PHP以一个服务php-fpm的形式出现,独立存在于Linux系统中,方便管理。
[root@xuexi-001 php-5.6.36]# useradd -s /sbin/nologin php-fpm
3.安装PHP
[root@xuexi-001 php-5.6.36]# ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl
编译参数和跟之前的文章不同,这里多了一个--enable-fpm,如果不加该参数,则不会有php-fpm执行文件生成,更不能启动php-fpm服务。
报错:
configure: error: Please reinstall the libcurl distribution -
easy.h should be in <curl-dir>/include/curl/
解决:
[root@xuexi-001 php-5.6.36]# yum install -y libcurl-devel
备注:
如果是第一次安装PHP,会有很多依赖包需要安装,这时你看错误提示,缺少什么包就安装什么包。
4.编译安装PHP
[root@xuexi-001 php-5.6.36]# make
[root@xuexi-001 php-5.6.36]# make install
5.修改配置文件:
[root@xuexi-001 php-5.6.36]# ls /usr/local/php-fpm/etc/
pear.conf php-fpm.conf.default
[root@xuexi-001 php-5.6.36]# cp php.ini-production /usr/local/php-fpm/etc/php.ini
[root@xuexi-001 php-5.6.36]# ls /usr/local/php-fpm/etc/
pear.conf php-fpm.conf.default php.ini
[root@xuexi-001 php-5.6.36]# vim /usr/local/php-fpm/etc/php-fpm.conf
添加如下内容:
[global] //定义全局参数
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www] //一个模块的名字
listen = /tmp/php-fcgi.sock //监听地址
listen.mode = 666 //监听的是sock时这行才生效,用来定义sock文件的权限是666
user = php-fpm //定义服务的用户
group = php-fpm //定义服务的用户组
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
6.检测配置
[root@xuexi-001 php-5.6.36]# /usr/local/php-fpm/sbin/php-fpm -t
[04-Jul-2018 00:09:44] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
7.拷贝启动脚本
[root@xuexi-001 php-5.6.36]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
8.修改启动脚本权限及添加服务到开机启动
[root@xuexi-001 php-5.6.36]# chmod 755 /etc/init.d/php-fpm
//更改权限
[root@xuexi-001 php-5.6.36]# chkconfig --add php-fpm
[root@xuexi-001 php-5.6.36]# chkconfig php-fpm on
//设置开机启动
[root@xuexi-001 php-5.6.36]# service php-fpm start
//启动php命令
Starting php-fpm done
[root@xuexi-001 php-5.6.36]# ps aux |grep php-fpm
