阿里云轻量级服务器的日常操作
1、使配置文件生效: source /etc/profile
2、查看配置环境path: echo $PATH
3、查看端口号: netstat -ano
查看当前运行程序的端口:netstat -anpl | grep LISTEN
4、启动防火墙:systemctl start firewalld 关闭防火墙:systemctl stop firewalld 重启防火墙:systemctl restart firewalld
5、禁止开机启动防火墙:systemctl disable firewalld 设置开机自动启动防火墙:systemctl enable firewalld.service
6、查看防火墙状态:firewall-cmd –state 重新刷新防火墙:firewall-cmd –reload
7、查看防火墙开通的端口:
firewall-cmd –permanent –list-ports
firewall-cmd –zone=public –list-ports
firewall-cmd –list-all
查看是否开通3306端口:firewall-cmd –query-port=3306/tcp
8、开放8080端口:firewall-cmd –zone=public –permanent –add-port=8080/tcp
9、开放3306端口:firewall-cmd –zone=public –add-port=3306/tcp –permanent
(注意:开放端口其实方法都可以,只要把端口号改了就可以)
10、移除8080端口:firewall-cmd –permanent –remove-port=8080/tcp
