Nginx反向代理实现域名不带端口访问网站

配置环境：Ubuntu 20.04 server

基本操作

安装nginx

apt update
apt install nginx

启动nginx

nginx

访问主域名，若看到如下图片则启动成功

关闭nginx

nginx -s stop

重启nginx

nginx -s reload

配置反向代理

进入安装nginx的文件夹，以/etc/nginx/为例

cd /etc/nginx/

打开配置文件

vim nginx.conf

修改配置文件如下

注意：

请修改配置文件中的域名及代理的ip地址及端口。

以下文件中分别对两个不同的端口进行了反向代理，如过只需代理一个端口，请注释掉Virtual Host Configs中另一个端口的代理配置。

同理，若想代理多个不同的端口到不同的二级域名下，可以新增server配置。

其中log功能以及其他功能可以按需开启。

	}

	server {

		server_name 	mc.xxx.cn;		#修改为域名
        
	         # access_log      logs/mc_logs/access.log;
             # error_log       logs/mc_logs/error.log;
		location / {
             proxy_pass http://43.xxx.xxx.xxx:xxxx;		#修改为ip + 端口
		}
	}

	include /etc/nginx/conf.d/*.conf;
	include /etc/nginx/sites-enabled/*;
}


#mail {
#	# See sample authentication script at:
#	# http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
#	# auth_http localhost/auth.php;
#	# pop3_capabilities "TOP" "USER";
#	# imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
#	server {
#		listen     localhost:110;
#		protocol   pop3;
#		proxy      on;
#	}
# 
#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}

保存配置文件，然后重启ngnix

测试

访问对应的域名网站，若看见成功打开网页则完成。

可以选择备份nginx文件以备使用

cp nginx.conf nginx.conf.bak
