我有两台 VoIP freepbx 服务器。我设置了服务器 A 并将其克隆到服务器 B 并更改了主机名和 IP。
服务器 B 上的 postfix 配置文件似乎被删除了 5 行，这破坏了 postfix，导致超过 100GB 的日志文件填满了根分区。 （一次又一次地发送电子邮件失败）
我已经通过每 30 分钟更新一个新的 postfix 配置文件来解决这个问题，但我很想知道问题是什么以及它是如何发生的。
我已将文件设置为 400 w/ postfix:nobody 权限，但它仍然发生！
[root@voip2 postfix]# ll main.cf
-r-------- 1 postfix nobody 1226 Apr 4 12:30 main.cf
这是 main.cf 以及我如何安装它：
cat << 'EOL' >/etc/postfix/main.cf

mydomain = domain.com
mydestination = $myhostname $myhostname.$mydomain localhost.$mydomain localhost

EOL
这是我的 main.cf 在随机混乱后的样子，这也是它一贯的样子：

这是隔夜日志文件的尾部：（这发生在我不在的那晚）

编辑：看来这更像是一个 FreePBX 问题，我已经找到了“罪魁祸首”，当我将 TGZ 文件从服务器 A 恢复到服务器 B 时，就会发生这种情况
