为什么守护进程不运行

2024-5-28 • tag-icon

我的守护进程曾经在 10.04 下运行，但在 12.04 上不再自动启动。如果我手动启动它

/etc/init.d/sqlexecd 启动，它起作用了。

这是 uname -a 的输出

Linux steamboy 3.2.0-30-generic-pae 
#48-Ubuntu SMP Fri Aug 24 17:14:09 UTC 2012 i686 i686 i386 GNU/Linux

以下是 chkconfig -l sqlexecd 的输出

sqlexecd                  0:off  1:off  2:on   3:on   4:on   5:on   6:off

这是守护进程。我很清楚它不会停止。

exit $?

这是日志中的错误。但是，手动启动后启动时不会发生此错误。

我还应该配置什么才能使其自动启动？

谢谢。

编辑：

这似乎是服务运行顺序依赖性问题，此后我已将其添加到我的守护进程中，包括 #!/bin/bash 后的 -e

#!/bin/bash -e

这些改变都无法改变原始错误。

答案1

Network driver cannot bind a name to the port.

我不熟悉 Informix，但我怀疑它只能在网络服务启动后启动。由于您使用的是 Red Hat 样式的 init 脚本，因此无法确保这一点。

如果你只是改变lsb 标头. 将整个sqlexecd脚本更改为 Debian 风格并重试。
