<p><span class="autocomment">关于在rc.local文件中指定用户执行脚本命令</span></p>
<p><b>新页面</b></p><div>=原因解析=<br />
<pre><br />
在centos7，使用ls -l /etc/rc.loacl可以看到如下结果<br />
lrwxrwxrwx. 1 root root 13 7月 31 22:02 /etc/rc.local -> rc.d/rc.local<br />
<br />
可以看到上面的执行结果是显示有执行权限的，<br />
但是当使用ls -l /etc/rc.d/rc.loacl的时候却可以看到如下结果<br />
-rw-r--r--. 1 root root 730 Sep 27 05:38 /etc/rc.d/rc.local<br />
/etc/rc.loacl所链接的文件是没有执行权限的，<br />
所以在启动的时候rc.local中写的命令得不到执行，<br />
因此需要手动添加执行权限给/etc/rc.d/rc.loacl</pre><br />
<br />
<br />
=解决办法=<br />
<pre><br />
Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure<br />
# that this script will be executed during boot.<br />
打开 就有提示哦 请用心看 哈哈 <br />
<br />
chmod +x /etc/rc.d/rc.local</pre><br />
<br />
=关于在rc.local文件中指定用户执行脚本命令=<br />
<pre><br />
使用su命令即可，命令格式：<br />
<br />
su - username -c “your-cammand” ,如：<br />
<br />
注意：指定用户执行的脚本（程序）目录，该用户必须有管理该脚本（程序）目录（文件）的权限。<br />
<br />
最好将该脚本（程序）目录的所有权给该用户：<br />
<br />
<br />
<br />
<br />
tail boot.log<br />
[ OK ] Started Network Time Service.<br />
[FAILED] Failed to start /etc/rc.d/rc.local Compatibility.<br />
See 'systemctl status rc-local.service' for details.<br />
<br />
#启动rc-local 服务 on aliyun 不要不小心 不清空了 /etc/rc.d/rc.local<br />
systemctl enable rc-local.service<br />
<br />
<br />
<br />
<br />
Failed to start /etc/rc.d/rc.local Compatibility<br />
<br />
#原内容哦 有时改了就不行 要原文件 <br />
cat /etc/rc.d/rc.local<br />
#!/bin/bash<br />
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES<br />
#<br />
# It is highly advisable to create own systemd services or udev rules<br />
# to run scripts during boot instead of using this file.<br />
#<br />
# In contrast to previous versions due to parallel execution during boot<br />
# this script will NOT be run after all other services.<br />
#<br />
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure<br />
# that this script will be executed during boot.<br />
