需求说明
使用三台主机分别搭建nginx，mysql，php组成lnmp架构
环境说明
| 系统平台 | ip | 需要安装的服务 |
|---|---|---|
| centos7，redhat7 | 172.16.11.13 | nginx |
| centos7，redhat7 | 172.16.11.14 | mysql |
| centos7，redhat7 | 172.16.11.15 | php |
lnmp平台软件安装顺序
nginx --> mysql --> php
①.关闭防火墙
[root@lizihan ~]# systemctl stop firewalld.service
②.关闭selinux
[root@lizihan ~]# setenforce 0
[root@lizihan ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
③.准备好需要的源码包和二进制包，可以自行下载
[root@lizihan ~]# ls
anaconda-ks.cfg mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
php-7.2.8.tar.xz nginx-1.14.0.tar.xz
nginx-1.14.0
mysql-5.7-22
php-7.2.8
④.配置一个网络源
[root@lizihan ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@lizihan yum.repos.d]# sed -i 's/$releasever/7/g' CentOS-Base.repo

①.修改/usr/local/php7/etc/php-fpm.d/www.conf
文件
[root@lizihan ~]# vim /usr/local/php7/etc/php-fpm.d/www.conf
listen = 172.16.11.15:9000 //修改为php服务器ip
;listen.allowed_clients = 172.16.11.13 //修改为nginx服务器ip
②.创建网页文件目录并创建文件
[root@lizihan ~]# mkdir /www/abc/ -p
[root@lizihan ~]# vim /www/abc/index.php
<?php

?>
[root@lizihan ~]# service php-fpm restart
验证
在window上添加域名与IP映射,在/windows/system32/drrvers/etc/hosts里面
