systemctl 解析殺死模式失敗，忽略混合

在 CentOS 7 上，我想檢查nginx服務的狀態：

# systemctl status nginx -l
nginx.service - The nginx HTTP and reverse proxy server
  Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled)
  Active: inactive (dead)

Jun 30 03:40:08 dev01 systemd[1]: [/usr/lib/systemd/system/nginx.service:13]
Failed to parse kill mode, ignoring mixed

然後我啟用了它：# systemctl enable nginx並再次檢查了它：

# systemctl status nginx -l
nginx.service - The nginx HTTP and reverse proxy server
  Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled)
  Active: inactive (dead)

Jun 30 03:40:08 dev01 systemd[1]: [/usr/lib/systemd/system/nginx.service:13]
Failed to parse kill mode, ignoring mixed

Jun 30 03:40:21 dev01 systemd[1]: [/usr/lib/systemd/system/nginx.service:13]
Failed to parse kill mode, ignoring mixed

這是什麼錯誤？為什麼每次我這樣做：# systemctl enable nginx，status在底部添加另一個錯誤副本。我enable連續做了 4 到 5 次，然後status顯示了 5 個這樣的錯誤。這個錯誤是關於什麼的？

此外，當我最終start服務時，所有這些錯誤都從status.

systemd 使用 syslog 將所有消息（啟動/停止）記錄到 /var/log/message，您看到的錯誤行基本上都是帶有 tail 選項的“nginx”的所有匹配行。它的東西 =~grep nginx | tail將顯示“nginx”grep 的 /var/log/message 的最後 10 行。基本上 systemctl 顯示日誌中的最後 10 行以幫助使用者辨識問題。

   [root@puppetmaster ~]# grep nginx /var/log/messages| tail
