将maven项目打包 jar到阿里云服务器时,总是访问不了,后来关闭了防火墙才行,所以记录下如下

 

 

关闭防火墙命令:systemctl stop firewalld.service

关闭 开机自启动:systemctl disable firewalld.service

 

 

1.查看防火墙状态

systemctl status firewalld

firewall-cmd --state #查看默认防火墙状态(关闭后显示notrunning,开启后显示running)

 

2.查看防火墙是否开机启动

systemctl is-enabled firewalld

3.关闭防火墙

systemctl stop firewalld

systemctl stop firewalld.service

systemctl status firewalld

4.禁用防火墙(系统启动时不启动防火墙服务)

systemctl disable firewalld

systemctl disable firewalld.service

systemctl is-enabled firewalld

 

 

关闭防火墙命令:systemctl stop firewalld.service

开启防火墙:systemctl start firewalld.service

关闭 开机自启动:systemctl disable firewalld.service

开启 开机启动:systemctl enable firewalld.service
