nginx资源分离实践

1.准备环境

2.配置web01服务器

1）配置nginx

[root@web01 ~]# vim /etc/nginx/conf.d/linux.sj.com.conf
server {
    listen 80;
    server_name linux.sj.com;
    charset utf8;

    location / {
        root /code/android;
        index index.html;
    }
}

[root@web01 ~]# systemctl restart nginx

2）创建站点目录

[root@web01 ~]# mkdir /code/android
[root@web01 ~]# echo "我是android" >> /code/android/index.html
[root@web01 ~]# chown -R www.www /code/android/

3）访问测试

1.配置hosts
10.0.0.7 linux.sj.com

3.配置web02服务器

1）配置nginx

[root@web02 ~]# vim /etc/nginx/conf.d/linux.sj.com.conf
server {
    listen 80;
    server_name linux.sj.com;
    charset utf8;

    location / {
        root /code/iphone;
        index index.html;
    }
}

2）创建站点文件

[root@web02 ~]# mkdir /code/iphone
[root@web02 ~]# echo "我是Iphone" >> /code/iphone/index.html
[root@web02 ~]# chown -R www.www /code/iphone/

3）访问测试

1.配置hosts
10.0.0.8 linux.sj.com

4.配置web03服务器

1）配置nginx

[root@web03 ~]# vim /etc/nginx/conf.d/linux.sj.com.conf
server {
    listen 80;
    server_name linux.sj.com;
    charset utf8;

    location / {
        root /code/pc;
        index index.html;
    }
}
[root@web02 ~]# systemctl restart nginx

2）创建站点文件

[root@web03 ~]# mkdir /code/pc -p
[root@web03 ~]# echo "我是pc端" >> /code/pc/index.html
[root@web03 ~]# chown -R www.www /code/

3）访问测试

1.配置hosts
10.0.0.9 linux.sj.com

5.配置负载均衡

1.配置nginx

[root@lb01 ~]# vim /etc/nginx/conf.d/linux.sj.com.conf
upstream android {
    server 10.0.0.7;
}

upstream iphone {
    server 10.0.0.8;
}

upstream pc {
    server 10.0.0.9;
}

server {
    listen 80;
    server_name linux.sj.com;

    location / {
        if ($http_user_agent ~* "Android") { #判断如果是安卓端
            proxy_pass http://android;       #代理到android虚拟主机池
        }
        if ($http_user_agent ~* "iPhone") {    #判断如果是苹果端
            proxy_pass http://iphone;       #代理到iphone虚拟主机池
        }
        if ($http_user_agent ~* "WOW64") {    #判断如果是IE浏览器
            return 403;                    #直接返回403
        }
        proxy_pass http://pc;               #如果没有匹配到以上内容，默认都代理到pc虚拟主机池
        include proxy_params;
    }
}

2.重启访问

1.重启
[root@lb01 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@lb01 ~]# systemctl restart nginx

2.配置hosts
10.0.0.4 linux.sj.com
