一、简单配置nginx的动静分离

假设web1为静态服务器，web2为动态服务器，node2做代理

1.1 根据目录分开

web1只处理静态请求

[root@web1 ~]# mkdir -p /var/www/www/image
[root@web1 ~]# yum -y install lrzsz
[root@web1 ~]# cd /var/www/www/image/
[root@web1 image]# rz
[root@web1 image]# ll
-rw-r--r--. 1 root root 156848 Mar 13 11:31 nhrzyx.png
[root@web2 ~]# vim /etc/httpd/conf/httpd.conf 
 DocumentRoot "/var/www/www"
[root@web2 ~]# systemctl restart httpd

web2只处理动态请求

[root@web2 ~]# mkdir -p /var/www/www/dynamic
[root@web2 ~]# echo dynamic10 > /var/www/www/dynamic/index.html
[root@web2 ~]# vim /etc/httpd/conf/httpd.conf 
 DocumentRoot "/var/www/www"
[root@web2 ~]# systemctl restart httpd

访问测试

http://172.25.254.134/image/nhrzyx.png

http://172.25.254.135/dynamic/index.html

1.2 通过请求分离

配置代理

[root@lb01 conf]# vim nginx.conf
worker_processes 1;
events {
  worker_connections 1024;
}
http {
  include    mime.types;
  default_type application/octet-stream;
  sendfile    on;
  keepalive_timeout 65;
upstream stack_pools {
    server 172.25.254.134:80 weight=5;
}
upstream dynamic_pools {
    server 172.25.254.135:80 weight=5;
}
  server {
    listen    80;
    server_name www.lbtest.com;
    location / {
      root  html;
      index index.html index.htm;
      proxy_set_header Host $host;
      proxy_pass http://dynamic_pools;
    }
    location /image/ {
      proxy_set_header Host $host;
    proxy_pass http://stack_pools;
    }
    location /dynamic/ {
      proxy_set_header Host $host;
    proxy_pass http://dynamic_pools;
    }
  }
}
[root@lb01 conf]# nginx -s reload

配置hosts ，浏览器访问测试

172.25.254.131 www.lbtest.com

http://www.lbtest.com/image/nhrzyx.png

http://www.lbtest.com/dynamic/

1.3 根据扩展名分离

[root@lb01 conf]# vim nginx.conf

worker_processes 1;
events {
  worker_connections 1024;
}
http {
  include    mime.types;
  default_type application/octet-stream;
  sendfile    on;
  keepalive_timeout 65;
upstream stack_pools {
    server 172.25.254.134:80 weight=5;
}
upstream dynamic_pools {
    server 172.25.254.135:80 weight=5;
}
  server {
    listen    80;
    server_name www.lbtest.com;
    location / {
      root  html;
      index index.html index.htm;
      proxy_set_header Host $host;
      proxy_pass http://dynamic_pools;
    }
    location ~ .*.(jpg|png|gif|css|js|swf|bmp|jsp|php|asp)$ {
    proxy_set_header Host $host;
    proxy_pass http://stack_pools;
    }
  }
}
[root@lb01 conf]# nginx -s reload

http://www.lbtest.com/image/nhrzyx.png 

1.4 根据客户端标识进行分离

http {
  include    mime.types;
  default_type application/octet-stream;
  sendfile    on;
  keepalive_timeout 65;
upstream stack_pools {
    server 172.25.254.134:80 weight=5;
}
upstream dynamic_pools {
    server 172.25.254.135:80 weight=5;
}
  server {
    listen    80;
    server_name www.lbtest.com;
    location / {
        if ($http_user_agent ~* "MSIE")
        {
            proxy_pass http://dynamic_pools;
        }
        if ($http_user_agent ~* "firefox")
        {
            proxy_pass http://stack_pools;
        }
    }
    proxy_set_header Host $host;
    }
}
[root@web1 image]# echo stack_web>> /var/www/www/test.html
[root@web1 image]# systemctl restart httpd

[root@web2 ~]# echo dynamic_web>>/var/www/www/test.html
[root@web2 ~]# systemctl restart httpd
