1.前提

虚拟机能连接外网

仿真http应用需在本虚拟机启用(原因：只有一台虚拟机做测试)

http_8080和http_8081要启用（http测试应用）

[root@cent79-2 ~]# ls -l http_*
-rwxr-xr-x 1 root root 6391676 Jul 19 13:39 http_8080
-rwxr-xr-x 1 root root 6391676 Jul 19 13:39 http_8081
[root@cent79-2 ~]# ./http_8080 &
[1] 1490
[root@cent79-2 ~]# ./http_8081 &
[2] 1496
[root@cent79-2 ~]# netstat -antulp |grep 8080

[root@cent79-2 ~]# netstat -antulp |grep 8081
tcp6       0      0 :::8081                 :::*                    LISTEN      1496/./http_8081    
[root@cent79-2 ~]# curl 192.168.10.156:8080
{"text":"I am one!"}
[root@cent79-2 ~]# curl 192.168.10.156:8081
{"text":"I am two!"}
[root@cent79-2 ~]#

2.Ngnix配置反向代理

2.1.Nginx配置单个反向代理

1>.编辑nginx配置文件nginx.conf，添加反向代理配置

user  nginx  nginx;

worker_processes  2;

worker_rlimit_nofile 1024;

error_log  /var/log/nginx/error.log notice;

pid        /var/run/nginx.pid;

events {

    use epoll;

    worker_connections  1024;

    multi_accept  on;

}

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;

    autoindex    on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {

    listen  80;

    server_name 192.168.10.156;

    location / {

      proxy_pass http://www.baidu.com;

    }

    }

}

2>.nginx语法验证

命令：

nginx -t

[root@cent79-2 ~]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@cent79-2 ~]#

3>.重启nginx

命令：

systemctl restart nginx

systemctl status nginx

[root@cent79-2 ~]# systemctl restart nginx

[root@cent79-2 ~]# systemctl status nginx
