我在 CentOS 7 中的 postfix 服务中遇到错误。
[root@iZ237ak0745Z postfix]# systemctl status postfix.service
● postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Fri 2016-11-18 04:07:59 CST; 34min ago

Nov 18 04:07:59 iZ237ak0745Z systemd[1]: postfix.service failed.
那么，谁能告诉我为什么我会得到postfix/postfix-script[6029]: fatal: the Postfix mail system is already running？
跑步后ps aux | grep postfix

答案1
请执行
'kill -9 5756 5759 7782 7798' 'systemctl start postfix' 'systemctl status postfix' 你应该看到它正在运行
