<h1>模板</h1>
下面开始进行我们自己的配置
<div class="cnblogs_code">
<pre>#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f nginx defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add nginx'

### BEGIN INIT INFO
# Provides: [程序名称，唯一]
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: [启动项的简短说明]
# Description: [启动项的完整说明]
### END INIT INFO

[需要执行的命令]

exit 0</pre>
</div>
咱们自己的
<div class="cnblogs_code">
<pre>#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f nginx defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add nginx'

### BEGIN INIT INFO
# Provides: myScript
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: myScript
# Description: myScript
### END INIT INFO

echo "myScript,hello word~~~" >>/home/myScript.txt

exit 0</pre>
</div>
~~~~~~~~~~~~~~
如果要运行脚本或者程序,可以定义变量，但是会涉及一个开机自启程序读取本地配置或者文件的问题。
不定义也行，哈哈哈
<div class="cnblogs_code">
<pre>BIN='/home/landv/go/src/aa/aa'

$BIN</pre>
</div>
BIN是一个变量自己随便搞
~~~~~~~~~~~~~~
接下来，我们给myScript加上可执行的属性
<ul>
<li>chmod + x myScript</li>
</ul>
然后加入开机启动项目中
　　“大便系列”
<ul>
<li>update-rc.d myScript defaults</li>
</ul>
 
删除开机启动项目
<ul>
<li>update-rc.d -f myScript remove</li>
</ul>
<h1>注意</h1>
/etc/init 是系统启动
/etc/init.d是应用启动
/etc/rc*.d这个是启动级别，具体级别含义请查询Linux启动级别
update-rc.d 这条命令就是把/etc/init.d/的配置加入这些级别中。

<h1>当然还有别的启动方式，先会这一种吧。</h1>
