1.在/etc/init.d/目录下新建脚本文件“jr”
注:脚本文件jr的内容格式,有严格规定。例程如下:
#! /bin/sh ### BEGIN INIT INFO # Provides: binfmt-support # Required-Start: $local_fs $remote_fs # Required-Stop: $local_fs $remote_fs # Default-Start: S 1 2 3 4 5 6 # Default-Stop: # Short-Description: Support for extra binary formats # Description: Enable support for extra binary formats using the Linux # kernel's binfmt_misc facility. ### END INIT INFO echo "xx" >> /jr/jr.txt exit 0
2.命令:#sudo update-rc.d jr defaults 98
//设置运行的优先级为98
//运行结果如下:
wu@ubuntu:~$ sudo update-rc.d jr defaults 98 update-rc.d: warning: jr start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (S 1 2 3 4 5 6) update-rc.d: warning: jr stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (none) Adding system startup for /etc/init.d/jr ... /etc/rc0.d/K98jr -> ../init.d/jr /etc/rc1.d/K98jr -> ../init.d/jr /etc/rc6.d/K98jr -> ../init.d/jr /etc/rc2.d/S98jr -> ../init.d/jr /etc/rc3.d/S98jr -> ../init.d/jr /etc/rc4.d/S98jr -> ../init.d/jr /etc/rc5.d/S98jr -> ../init.d/jr//表示已经在/etc/rcX.d/的相应目录下,创建启动脚本成功。
3.为了验证一下,可以运行#sysv-rc-conf
找到相应名称的脚本,看启动标志打开了没有。
4.放心地重启吧,看看效果。
