当我重新启动 Ubuntu 服务器时，如何让 sphinx 重新启动？

我在我的 ubuntu 9.04 服务器上构建并安装了 sphinx 搜索。

如何让 sphinx 守护进程在重启时自动启动？

答案1

我不了解 Sphinx，但这是基本方法。创建一个文件/etc/init.d/searchd包含以下内容（还有这个脚本，但您可能需要稍微调整一下）：

#!/bin/bash

case "${1:-''}" in
  'start')
        # put the command to start sphinx
        # i.e., /usr/bin/searchd start or /usr/bin/searchd --daemon or whatever the command is
        ;;
  'stop')
        # stop command here
        ;;
  'restart')
        # restart command here
        ;;
  *)
        echo "Usage: $SELF start|stop|restart"
        exit 1
        ;;
esac

然后执行以下操作：

$ sudo update-rc.d searchd defaults

要手动控制服务：

$ sudo /etc/init.d/searchd <start|stop|restart>

我们在 Debian 系统上为客户部署了 Sphinx，并使用运行来管理进程。我们不必编写特殊的初始化脚本，而且由于我们在其他平台（主要是 CentOS/RHEL）上使用 Runit，因此它具有完美的可移植性。

本文撰写时为 ubuntu 打包的 sphinx 版本（0.99）具有下面的启动脚本。

我将它重新用于从源代码编译的 2.0.1 beta，只需更改一行DAEMON=/usr/local/..就可以了。

创建一个简短的脚本文件（也许是 bash），其中包含与以下行等效的内容：

/path/to/sphinx/installation/searchd --config /path/to/sphinx/config/sphinx.conf &

然后以 root 身份将脚本移至 /etc/init.d，并 chmod 该脚本（“chmod +x myscript.sh”）
