• FirewallD is not running


    在linux开放6379端口时,提示 FirewallD is not running,发现防火墙没有开启。

    问题发现

    [root@VM_0_9_centos redis-4.0.8]#  firewall-cmd --zone=public --add-port=6379/tcp --permanent
    FirewallD is not running

    查看防火墙状态

    [root@VM_0_9_centos redis-4.0.8]# systemctl status firewalld
    ● firewalld.service - firewalld - dynamic firewall daemon
       Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
       Active: inactive (dead)
         Docs: man:firewalld(1)

    发现当前是dead状态,即防火墙未开启。

    开启防火墙

    [root@VM_0_9_centos redis-4.0.8]# systemctl start firewalld

    没有任何提示,表示开启成功。

    检查防火墙状态

    [root@VM_0_9_centos redis-4.0.8]# systemctl status firewalld
    ● firewalld.service - firewalld - dynamic firewall daemon
       Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
       Active: active (running) since Tue 2020-10-27 16:28:08 CST; 11s ago
         Docs: man:firewalld(1)
     Main PID: 32232 (firewalld)
        Tasks: 2
       Memory: 32.0M
       CGroup: /system.slice/firewalld.service
               └─32232 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid

    Oct 27 16:28:08 VM_0_9_centos systemd[1]: Started firewalld - dynamic firewall daemon.

    防火墙开启成功。

    关闭防火墙

    [root@VM_0_9_centos redis-4.0.8]# systemctl stop firewalld

    再次开放6379端口

    [root@VM_0_9_centos redis-4.0.8]# firewall-cmd --zone=public --add-port=6379/tcp --permanent
    success

    重启防火墙使配置即使生效

    [root@VM_0_9_centos redis-4.0.8]# systemctl restart firewalld

    查看系统所开放的端口

    [root@VM_0_9_centos redis-4.0.8]# firewall-cmd --zone=public --list-ports
    6379/tcp

    结束!
