Centos开启防火墙超时失败

CnetOS命令

CentOS关闭防火墙命令：

systemctl stop firewalld
# 或者
service firewalld stop

CentOS启动防火墙

systemctl start firewalld
# 或者
service firewalld start

关闭防火墙后再次启动防火墙，发现无法启动，错误是超时:

[root@localhost ~]service firewalld restart
Redirecting to /bin/systemctl restart firewalld.service
Job for firewalld.service failed because a timeout was exceeded. See "systemctl status firewalld.service" and "journalctl -xe" for details.

解决办法：

需要关闭firewalld进程，再启动firewalld

systemctl stop firewalld    #停止firewalld
pkill -f firewalld   #关闭firewalld进程
systemctl start firewalld    #启动firewalld

官方解释可能原因： systemd didn’t know about the process that it didn’t start in the first place of course
