postfix 启动报错

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。
