Nginx_安装配置后，浏览器不能访问配置的站点ip：防火墙

一、检查nginx安装成功

[root@localhost softRyc]# /usr/local/webserver/nginx/sbin/nginx -v
nginx version: nginx/1.21.2

 

二、配置检查成功

[root@localhost conf]# /usr/local/webserver/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/webserver/nginx/conf/nginx.conf test is successful

 

三、检查nginx已启动

[root@localhost conf]# ps -ef |grep nginx
root 18239 1 0 11:13 ? 00:00:00 nginx: master process /usr/local/webserver/nginx/sbin/nginx
www 18240 18239 0 11:13 ? 00:00:00 nginx: worker process
www 18241 18239 0 11:13 ? 00:00:00 nginx: worker process
root 18246 14959 0 11:13 pts/2 00:00:00 grep --color=auto nginx

 

问题：访问对应站点域名失败

          http://192.168.XXX.XXX:80

 

首先想到的是端口被防火墙拦截了

顺利解决，方法如下

1、查看防火墙允许的端口：发现只有8080是放开的

[root@localhost conf]# firewall-cmd --list-ports
8080/tcp

2、查看自己的配置文件：/usr/local/webserver/nginx/conf/nginx.conf中，默认的端口是80

3、将80端口加到防火墙允许的端口
[root@localhost conf]#
[root@localhost conf]# firewall-cmd --permanent --zone=public --add-port=80/tcp
success
[root@localhost conf]#

 

4、重启下防火墙设置
[root@localhost conf]# firewall-cmd --reload
success

5、再次查看（已添加80端口）
[root@localhost conf]# firewall-cmd --list-ports
8080/tcp 80/tcp

6、再次访问，成功了，问题解决
