Web集群案例实战 -- Nginx 反向代理 -- 案例实战

前言

本环境是基于 Centos 7.8 系统构建Nginx学习环境
具体构建，请参考 Nginx-1.18.0 环境部署

---

环境准备

role	host	ip	nginx-version	OS
nginx proxy host	node01	192.168.5.11	Nginx-1.18.0	Centos 7.8
nginx web server1	node02	192.168.5.12	Nginx-1.18.0	Centos 7.8
nginx web server2	node02	192.168.5.13	Nginx-1.18.0	Centos 7.8
nginx client1	node04	192.168.5.14	----	Centos 7.8
nginx client2	windows 7 Ultimate.	192.168.5.7	----	windows 7 Ultimate.

配置后端 web服务

---node02
[root@node02 ~]# echo "`hostname -I`www" > /usr/share/nginx/html/www/index.html
[root@node02 ~]# echo "`hostname -I`bbs" > /usr/share/nginx/html/bbs/index.html
[root@node02 ~]# vim /etc/nginx/conf.d/vhost.conf
server {
     
    listen       80;
    server_name  bbs.yunjisuan.com;
    location / {
     
        root   /usr/share/nginx/html/bbs;
        index  index.html index.htm;
    }
}

server {
     
    listen       80;
    server_name  www.yunjisuan.com;
    location / {
     
        root   /usr/share/nginx/html/www;
        index  index.html index.htm;
    }
}
[root@node02 ~]# systemctl restart nginx


---node03
[root@node03 ~]# mkdir /usr/share/nginx/html/{www,bbs}
[root@node03 ~]# echo "`hostname -I`www" > /usr/share/nginx/html/www/index.html
[root@node03 ~]# echo "`hostname -I`bbs" > /usr/share/nginx/html/bbs/index.html
[root@node03 ~]# vim /etc/nginx/conf.d/default.conf 
server {
     
    listen       80;
    server_name  bbs.yunjisuan.com;
    location / {
     
        root   /usr/share/nginx/html/bbs;
        index  index.html index.htm;
    }
}

server {
     
    listen       80;
    server_name  www.yunjisuan.com;
    location / {
     
        root   /usr/share/nginx/html/www;
        index  index.html index.htm;
    }
}
[root@node03 ~]# systemctl restart nginx

配置反向代理服务器

添加hosts解析

[root@node01 ~]# vim /etc/hosts
192.168.5.11 web.wan.org
192.168.5.12 www.yunjisuan.com bbs.yunjisuan.com
192.168.5.13 www.yunjisuan.com bbs.yunjisuan.com

[root@node01 ~]# vim /etc/nginx/conf.d/vhost.conf
server {
     
    listen       80;
    server_name  web.wan.org;
    location / {
     
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

location /bbs {
     
    proxy_pass http://192.168.5.12/bbs/;
    }
location /www {
     
    proxy_pass http://192.168.5.12/www/;
    }
}
[root@node01 ~]# systemctl restart nginx

node04测试

添加hosts解析

[root@node04 ~]# vim /etc/hosts
192.168.5.11 web.wan.org
192.168.5.12 www.yunjisuan.com bbs.yunjisuan.com
192.168.5.13 www.yunjisuan.com bbs.yunjisuan.com
