postfix與sendmail衝突，postfixsendmail

在Linux伺服器（CentOS release 6.6）上配置好了sendmail後，測試發送郵件時發現有問題，檢查sendmail服務的狀態，發現其處於“sendmail dead but subsys locked”， 檢查發現postfix服務也在運行。只需要將postfix服務停掉即可。為什麼會出現這種情況呢？Something was occasionally causing the postfix service to start which then caused the status of sendmail to jump to dead but subsys locked. 兩種似乎不相容。

操作步驟：

1：檢查sendmail服務的狀態

[root@DB-Server ~]# service sendmail status

sendmail dead but subsys locked

sm-client (pid  22112) is running...

 

2：檢查postfix服務的狀態

[root@DB-Server ~]# service postfix status

master (pid  1777) is running...

 

3：停止postfix服務

[root@DB-Server ~]# service postfix stop

Shutting down postfix: [  OK  ]

 

4：重新啟動sendmail服務

[root@DB-Server ~]# service sendmail stop

Shutting down sm-client: [  OK  ]

Shutting down sendmail: [FAILED]

[root@DB-Server ~]# service sendmail stop

[root@DB-Server ~]# service sendmail start

Starting sendmail: [  OK  ]

Starting sm-client: [  OK  ]

5：禁用postfix在reboot後自動啟動

      檢查一下是否有設定 postfix 在 reboot 後自動啟動
chkconfig --list | grep postfix

chkconfig postfix off
