Daemon
為什麼守護程序不執行
我的守護程序曾經在 10.04 下執行，但在 12.04 上不再自動啟動。如果我手動啟動它
/etc/init.d/sqlexecd 啟動，它可以工作。
這是 uname -a 的輸出
Linux steamboy 3.2.0-30-generic-pae #48-Ubuntu SMP Fri Aug 24 17:14:09 UTC 2012 i686 i686 i386 GNU/Linux這是 chkconfig -l sqlexecd 的輸出
sqlexecd 0:off 1:off 2:on 3:on 4:on 5:on 6:off這是守護程序。我很清楚它不會停止。

謝謝。
編輯：
這似乎是一個服務執行順序依賴問題，我已經將它添加到我的守護程序中，包括 #!/bin/bash 之後的 -e
#!/bin/bash -e ### BEGIN INIT INFO # Provides: sqlexecd # Required-Start: $network $syslog # Required-Stop: $network $syslog # Default-Start: 3 5 # Default-Stop: 1 # Short-Description: Simple script to run Informix SE daemon. ### END INIT INFO #這些更改都不會改變原始錯誤。
這是根據要求的網路守護程序：

Network driver cannot bind a name to the port.我對 Informix 不熟悉，但我懷疑它只能在網路服務啟動後才能啟動。由於您使用的是 Red Hat 風格的初始化腳本，因此無法確保這一點。
僅更改lsb 標頭是不夠的。將整個
sqlexecd腳本更改為 Debian 樣式，然後重試。
