CentOS postfix启动报错net_interfaces: no local interface

CentOS 7 postfix启动报错： inet_interfaces: no local interface found for ::1

当前环境CentOS 7.4

[root@test ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
[root@test ~]# uname -r
3.10.0-693.2.2.el7.x86_64

使用systemctl start postfix时，总是提示：
Job for postfix.service failed because the control process exited with error code. See “systemctl status postfix.service” and “journalctl -xe” for details.

重启也无效，查看日志more /var/log/maillog 或者 more /var/log/message
发现日志有报错信息：
postfix: fatal: parameter inet_interfaces: no local interface found for ::1
重启服务器也没有解决

解决方法：
vi /etc/postfix/main.cf

发现配置为：

inet_interfaces = localhost

inet_protocols = all

改成：

inet_interfaces = all 或者 inet_interfaces = 127.0.0.1

inet_protocols = all

重新启动postfix服务即可

systemctl start postfix

CentOS 6 系统类似，只是启动或重启服务的命令不同
