哪些守护进程可以在启动时停止加载？

Question

以下是从chkconfig实用程序获得的列表。我想知道哪些守护进程可以在不丢失任何附加功能的情况下安全停止？

Answer 1

这可能是一个愚蠢的答案，但就像评论中的每个人都指出的那样，不必要是相对的。这完全取决于您的系统以及您想用它做什么。不知道有没有人能给你一个完美的答案。

如果你真的想简化你的启动过程，最好的办法就是研究这些守护进程中的每一个。谷歌他们每个人，找出他们做什么。然后禁用它。尝试启动。使用您的系统，看看哪些有效，哪些无效。没有那个守护进程你能活下去吗？它是否破坏了您的启动过程？如果需要，请重新启用它，转到下一个。

这样做的好处是你会多次破坏你的系统。反过来，您必须弄清楚如何修复它，并且您将对 Ubuntu 和 linux 的工作方式有更好的了解。然后你可以回到这里回答很多问题;p

哦，还有，备份。随时备份。或者您可以采纳 Luri 的明智建议并在您的虚拟机中运行测试安装。
