關閉防火牆
centos:
- 關閉selinux:
vi /etc/sysconfig/selinux 修改 ... SELINUX=disabled ... 修改完後 reboot
- 防火牆開啟某端口:
7: firewall-cmd --zone=public --add-port=8888/tcp --permanent 6: iptables -A INPUT -p tcp --dport 8080 -j ACCEPT /etc/rc.d/init.d/iptables save /etc/init.d/iptables restart
- 防火牆關閉某端口:
firewall-cmd --zone=public --remove-port=8888/tcp --permanent
- 防火牆查看某個端口狀態:
firewall-cmd --query-port=8888/tcp
- 查看已經開放的端口:
7: firewall-cmd --list-ports 6: /etc/init.d/iptables status
- 重啟防火牆:
7: firewall-cmd --reload 6: service iptables restartd
- 關閉防火牆:
7: systemctl stop firewalld.service 6: service iptables stop
- 開啟防火牆:
7: systemctl start firewalld.service 6: service iptables start
- 設置開機自啟
7: systemctl enable firewalld.service 6: chkconfig iptables on
- 設置開啟不自啟
7: systemctl disable firewalld.service 6: chkconfig iptables off
