Nginx负载均衡实现动静分离

实验拓扑

原本应该有5台主机，2台放动态资源，2台放静态资源，一台做nginx负载均衡器，但是我们资源有限，九江4台资源机变成了2台，但是结果不受影响

实验环境：

系统	主机名	需要安装的服务	IP
Centos8	Nginx-LB	Nginx	192.168.169.139
Centos8	LNMP	Nginx+MySQL+PHP	192.168.169.140
Centos8	LAMP	Httpd+MySQL+PHP	192.168.169.142

1. 前置实验环境准备

1.1 关闭防火墙和selinux

 //三台主机关闭防火墙和selinux
systemctl disable --now firewalld
sed -ri 's/(SELINUX=).*/\1disabled/g' /etc/selinux/config 
reboot

1.2 修改主机名

 //Nginx-LB
[root@localhost ~]# hostnamectl set-hostname Nginx-LB
[root@localhost ~]# bash
[root@Nginx-LB ~]#
 
//LNMP
[root@localhost ~]# hostnamectl set-hostname LNMP
[root@localhost ~]# bash
[root@LNMP ~]#
 
//Apache
[root@localhost ~]# hostnamectl set-hostname LAMP
[root@localhost ~]# bash
[root@LAMP ~]#

1.3 配置网络源

 //三台主机配置网络源
rm -f /etc/yum.repos.d/*
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
dnf clean all
dnf makecache

2. 在Nginx-LB主机上安装nginx

 //安装所需工具和依赖包
[root@Nginx-LB ~]# dnf -y install gcc gcc-c++ make wget vim pcre-devel openssl openssl-devel gd-devel
 
 
//创建nginx用户
[root@Nginx-LB ~]# useradd -rMs /sbin/nologin nginx
 
//下载nginx1.22安装包
[root@Nginx-LB ~]# cd /usr/src
[root@Nginx-LB src]# wget https://nginx.org/download/nginx-1.22.0.tar.gz
 
//解压nginx安装包
[root@Nginx-LB src]# tar xf nginx-1.22.0.tar.gz

[root@Nginx-LB nginx]# ls
conf  html  logs  sbin
 
//配置nginx全局环境变量
[root@Nginx-LB nginx]# echo "export PATH=\$PATH:/usr/local/nginx/sbin" > /etc/profile.d/nginx.sh
[root@Nginx-LB nginx]# source /etc/profile.d/nginx.sh 
[root@Nginx-LB nginx]# which nginx

5. 在Nginx-LB主机上开负载均衡和反向代理

 [root@Nginx-LB ~]# cd /usr/local/nginx/
[root@Nginx-LB nginx]#
#在http段配置如下内容
upstream dynamic {
        server 192.168.169.140;		//动态资源放在哪里就写那台主机的IP+端口
        server 192.168.169.142:82;
    }
 
upstream static {
        server 192.168.169.140;		//静态资源放在哪里就写哪台主机的IP+端口
        server 192.168.169.142;
    }
 
#在server段进行如下配置
location / {
            proxy_pass http://static; //因为负载均衡器不需要主页，直接修改默认的location段
        }
//取消如下内容的注释
location ~ \.php$ {
            proxy_pass   http://127.0.0.1;
        }
//进行修改
location ~ \.php$ {
            proxy_pass   http://dynamic;
        }
 
//重启nginx
[root@Nginx-LB nginx]# systemctl restart nginx.service

6. 进行验证

访问Nginx-LB主机的IP

此时我们访问到的是静态网页，并且nginx和apache做轮询

刷新，重新加载

访问Nginx-LB主机的IP+index.php

现在我们访问到的是php动态网页，同样也是LNMP和LAMP两台主机轮询

刷新，重新加载
