⽤nginx做负载均衡服务器，配置动静分离

⽤nginx做负载均衡服务 器，配置动静分离

---

题目：
后端RS服务器⼀台部署LNMP(nginx1.22+mysql8.0+php8.1)，⼀台部署
httpd。
要求nginx和php使⽤编译安装
最后要通过访问nginx负载均衡服务器的IP看到动静分离的效果。

环境准备：

部署LNMP ，做动态资源

nginx安装

//首先关闭防火墙和selinux
[root@node1 ~]# setenforce 0
[root@node1 ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@node1 ~]# systemctl disable  --now firewalld.service 

//创建用户
[root@node1 ~]# useradd -rMs /sbin/nologin nginx

//安装所需要的依赖包
[root@node1 ~]# dnf -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++ make wget vim

//下载nginx源码包，并解压
[root@node1 ~]# wget https://nginx.org/download/nginx-1.22.0.tar.gz
[root@node1 ~]# tar -xf nginx-1.22.0.tar.gz 
[root@node1 ~]# cd nginx-1.22.0/
[root@node1 nginx-1.22.0]# 

//编译安装
[root@node1 nginx-1.22.0]# ./configure \
> --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-debug \
> --with-http_ssl_module \
> --with-http_realip_module \
> --with-http_image_filter_module \
> --with-http_gunzip_module \
> --with-http_gzip_static_module \
> --with-http_stub_status_module 

//开启编译安装
[root@node1 nginx-1.20.2]# make -j $(grep 'processor' /proc/cpuinfo | wc -l) && make install

//安装成功
[root@node1 nginx-1.22.0]# cd /usr/local/nginx/
[root@node1 nginx]# ls
conf  html  logs  sbin
