Linux安装Nginx

[root@VM-20-12-centos data]# yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

• Nginx安装包可以在http://nginx.org/下载

• [root@VM-20-12-centos data]# wget https://nginx.org/download/nginx-1.18.0.tar.gz
  [root@VM-20-12-centos data]# tar -zxvf nginx-1.18.0.tar.gz
  [root@VM-20-12-centos data]# rm -rf nginx-1.18.0.tar.gz [root@VM-20-12-centos data]# cd  nginx-1.18.0
  [root@VM-20-12-centos nginx-1.18.0]# ./configure
  [root@VM-20-12-centos nginx-1.18.0]# make
  [root@VM-20-12-centos nginx-1.18.0]# make install

• 为安全起见，使用专门的用户和组业启动nginx

  [root@VM-20-12-centos nginx-1.18.0]# groupadd -f nginx_group
  [root@VM-20-12-centos nginx-1.18.0]# useradd -g nginx_group nginx_worker

• 修改nginx配置文件

  [root@VM-20-12-centos nginx-1.18.0]# vim /usr/local/nginx/conf/nginx.conf
   user nginx_worker nginx_group;

  在 #gzip  on; 后面加入下面配置 :

   #gzip  on;
  upstream backend{
  	server 192.168.86.130:8080;
  	server 192.168.86.131:8080;
  	ip_hash;
  }

  修改server {location / { }}其中 proxy_pass 参数和 upstream backend{} 对应

           location / {
              root	html;
              index	index.html index.htm index.jsp;
  			proxy_pass  http://backend;
  			proxy_redirect	off; 
  			proxy_set_header	Host $host; 
  			proxy_set_header	X-Real-IP $remote_addr; 
  			proxy_set_header	X-Forwarded-For $proxy_add_x_forwarded_for; 
  			client_max_body_size	10m; 
  			client_body_buffer_size	128k; 
  			proxy_connect_timeout	90; 
  			proxy_send_timeout	90; 
  			proxy_read_timeout	90; 
  			proxy_buffer_size	4k; 
  			proxy_buffers	4 32k; 
  			proxy_busy_buffers_size	64k; 
  			proxy_temp_file_write_size	64k;
          }

• 启动、停止nginx

  [root@VM-20-12-centos nginx-1.18.0]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
  [root@VM-20-12-centos nginx-1.18.0]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf -s quit
