Linux安装Nginx

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

1. 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

2. 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

3. 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;
           }

4. 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
