nginx负载均衡配置实现动静分离

nginx负载均衡配置实现动静分离 反向代理与负载均衡

环境说明

主机名IP服务nginx192.168.129.3nginxagent192.168.129.33nginxhttpd192.168.129.133httpd

注：nginx服务都是源码安装 、httpd为yum安装
准备工作
每台主机开启服务，并关闭防火墙与selinux

修改配置

[root@agent ~]# vim /usr/local/nginx/conf/nginx.conf
......

    #gzip  on;

    upstream webservers {                        #配置负载均衡
        server 192.168.129.3;
        server 192.168.129.133;
    }
    

    server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {                       #配置反向代理
            proxy_pass http://webservers;
        }

        #error_page  404              /404.html;

......

[root@agent ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@agent ~]# nginx -s reload

使用agent主机IP地址访问，并刷新测试

修改agent主机配置文件

[root@agent ~]# vim /usr/local/nginx/conf/nginx.conf
......
    #gzip  on;
    upstream static {                   
        server 192.168.129.33;			#httpd主机的ip
    }
   
    upstream dynamic {             
        server 192.168.129.135;         #lnmp主机的ip
    }

    server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            proxy_pass http://static;       			#访问静态资源会自动跳转到进行访问
        }
        #error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        
        location ~ .php$ {
            proxy_pass   http://dynamic;               #访问动态资源会自动跳转到进行访问
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
......

[root@agent ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@agent ~]# 
[root@agent ~]# nginx -s reload

使用agent主机IP地址访问测试

• 访问静态资源
  

• 访问动态资源
