2. 配置nginx

sudo gedit /etc/nginx/nginx.conf

user  www-data;
worker_processes  ;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  ;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  ;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    #real server 即66和67
    upstream cluster {
        server localhost:8080;
        server 192.168.2.67:8080;
    }  

    server {
        listen       80;
        server_name  192.168.2.68;
        location ~ ^/NginxStatus/ {
            stub_status on;
            access_log off;
        }

        location ~ ^/(WEB-INF)/ {
            deny all;
        }

　　　　 #将所有访问happyAdmin的请求都转发到67
        location /happyAdmin/ {
            proxy_pass http://192.168.2.67:8080/happyAdmin/;
            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;
        }

　　　　 #将剩余请求按照cluster配置进行负载
        location / {
            proxy_pass http://cluster;
            proxy_set_header Host $host;
        }

        #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;
        }
    }

}

3. 重启

sudo service nginx restart

如果出现错误可以通过/var/log/nginx/error.log   /var/log/nginx/access.log进行调试。
