我是centos8得主机

安装命令:

yum install nginx

如果为Ubuntu主机

sudo apt-get install nginx

安装完成后，启用并启动Nginx服务：

sudo systemctl enable nginxsudo systemctl start nginx

然后我们有2个服务：

一个地址为: http://xxxxxx1:50631/index.html一个为:     http://xxxxxx2:50631/index.html

 

 

 

接下来修改 nginx.conf 配置代理：

 然后我们再回来配置Nginx，进入 /etc/nginx，然后 vi 修改nginx.conf ，保存

 

再liunx 使用 vi编辑命令如果要修改需要按键盘 i键

如果要退出保存需要按esc 然后输入  :wq   注意这里前面有个冒号

修改以下内容得东西

全部内容如下：

#user  nobody;
worker_processes  1;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {worker_connections  1024;
}http {include       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  logs/access.log  main;sendfile        on;#tcp_nopush     on;#keepalive_timeout  0;keepalive_timeout  65;#gzip  on;upstream rtservice {server xxxxxx1:50631;server xxxxxx2:50631;}server {listen   50501;server_name 你的域名;location /{proxy_pass   http://rtservice;index  index.html index.htm;}location = /50x.html {root   html;}}# another virtual host using mix of IP-, name-, and port-based configuration##server {#    listen       8000;#    listen       somename:8080;#    server_name  somename  alias  another.alias;#    location / {#        root   html;#        index  index.html index.htm;#    }#}# HTTPS server##server {#    listen       443 ssl;#    server_name  localhost;#    ssl_certificate      cert.pem;#    ssl_certificate_key  cert.key;#    ssl_session_cache    shared:SSL:1m;#    ssl_session_timeout  5m;#    ssl_ciphers  HIGH:!aNULL:!MD5;#    ssl_prefer_server_ciphers  on;#    location / {#        root   html;#        index  index.html index.htm;#    }#}}

保存以后使用命令重启nginx

nginx -s reload

如果重启报错

启动nginx: [error] open() “/var/run/nginx/nginx.pid“ failed (2: No such file or directory)

那么就执行

nginx 
nginx -s reload

完成后我们访问域名+端口

nginx已经成功运行了
