端口开放

1.开启防火墙

systemctl start firewalld

2.查看防火墙所有开放的端口

firewall-cmd --zone=public --list-ports

3.查看端口是否打开

firewall-cmd --zone=public --query-port=8090/tcp
firewall-cmd --zone=public --query-port=8080/tcp
firewall-cmd --zone=public --query-port=7500/tcp
firewall-cmd --zone=public --query-port=7000/tcp
firewall-cmd --zone=public --query-port=8080/tcp
firewall-cmd --zone=public --query-port=3306/tcp
firewall-cmd --zone=public --query-port=6000/tcp
firewall-cmd --zone=public --query-port=8600/tcp
firewall-cmd --zone=public --query-port=9105/tcp

4.开放指定端口

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=3000/tcp --permanent
firewall-cmd --zone=public --add-port=8090/tcp --permanent
firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --zone=public --add-port=7500/tcp --permanent
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-port=7000/tcp --permanent
firewall-cmd --zone=public --add-port=8081/tcp --permanent
firewall-cmd --zone=public --add-port=6000/tcp --permanent
firewall-cmd --zone=public --add-port=6001/tcp --permanent
firewall-cmd --zone=public --add-port=6002/tcp --permanent
firewall-cmd --zone=public --add-port=6003/tcp --permanent
firewall-cmd --zone=public --add-port=8600/tcp --permanent
firewall-cmd --zone=public --add-port=10080/tcp --permanent
firewall-cmd --zone=public --add-port=9100/tcp --permanent
firewall-cmd --zone=public --add-port=9101/tcp --permanent
firewall-cmd --zone=public --add-port=9102/tcp --permanent
firewall-cmd --zone=public --add-port=9103/tcp --permanent
firewall-cmd --zone=public --add-port=6004/tcp --permanent
firewall-cmd --zone=public --add-port=8001/tcp --permanent
firewall-cmd --zone=public --add-port=4000/tcp --permanent
firewall-cmd --zone=public --add-port=9105/tcp --permanent

5.重启防火墙

firewall-cmd --reload

6.关闭某个端口

firewall-cmd --zone=public --remove-port=9103/tcp --permanent
