今天在启动postfix的时候，查看centos中的postfix日志 more /var/log/maillog，出现了如下报错，
Apr 28 09:04:44 PaulV1 aliasesdb[23836]: /usr/sbin/postconf: fatal: parameter inet_interfaces: no local interface found for ::1 Apr 28 09:04:45 PaulV1 aliasesdb[23836]: newaliases: fatal: parameter inet_interfaces: no local interface found for ::1 Apr 28 09:04:45 PaulV1 postfix[23844]: fatal: parameter inet_interfaces: no local interface found for ::1
后来查看了下配置文件 vi /etc/postfix/main.cf
将配置为：
inet_interfaces = localhost inet_protocols = all
改成了：
inet_interfaces = all inet_protocols = all
接着重新启动，又出现了如下信息
Apr 28 09:09:08 PaulV1 postfix[23919]: postsuper: fatal: scan_dir_push: open directory defer: Permission denied Apr 28 09:09:08 PaulV1 postfix/postsuper[23952]: fatal: scan_dir_push: open directory defer: Permission denied Apr 28 09:09:10 PaulV1 postfix/postfix-script[23953]: fatal: Postfix integrity check Failed!
这是因为启动时邮件服务对系统目录没有权限导致的，我们更改相关目录的所有者，然后重新启动
chown -R postfix /var/spool/postfix/
但是。启动的时候显示还有一个目录没有权限。
Apr 28 09:21:57 PaulV1 postfix/master[24146]: fatal: open lock file /var/lib/postfix/master.lock: cannot open file: Permission denied Apr 28 09:21:58 PaulV1 postfix/master[24145]: fatal: daemon initialization failure Apr 28 09:21:59 PaulV1 postfix/postfix-script[24147]: fatal: mail system startup Failed
所以
chown -R postfix /var/lib/postfix/
最后。才启动成功了。
[root@V1 ~]# systemctl status postfix -l
