ubuntu系统中/etc/rc.local和/etc/init.d/rc.local的区别详解

前言

我们在ubuntu下要把一个程序加入开机启动，一般可以通过修改rc.local来完成，但ubuntu下有两个rc.local文件。分别是/etc/rc.local和/etc/init.d/rc.local。可以看一下两个文件的内容找到他俩的关系：

/etc/init.d/rc.local

#! /bin/sh### BEGIN INIT INFO# Provides:  rc.local# Required-Start: $all# Required-Stop:# Default-Start: 2 3 4 5# Default-Stop:# Short-Description: Run /etc/rc.local if it exist### END INIT INFOPATH=/sbin:/usr/sbin:/bin:/usr/bin. /lib/init/vars.sh. /lib/lsb/init-functionsdo_start() { if [ -x /etc/rc.local ]; then  [ "$VERBOSE" != no ] && log_begin_msg "Running local boot scripts (/etc/rc.local)" /etc/rc.local ES=$? [ "$VERBOSE" != no ] && log_end_msg $ES return $ES fi}case "$1" in start) do_start ;; restart|reload|force-reload) echo "Error: argument '$1' not supported" >&2 exit 3 ;; stop) ;; *) echo "Usage: $0 start|stop" >&2 exit 3 ;;esac
