建立自启动脚本

时间：2006-01-24 来源：cnscn2008

[platform]  redhat 1)创建脚本如下
[cnscn@MagicLinux ~]$ cat /etc/rc.d/init.d/iptablerules
#!/bin/bash
# 一定要有下面两行，做为chkconfig的运行级别、优先级别、描述
# chkconfig: 345 85 15
# description: this is the iptables rules list
#
.....
2)应用服务创建程序
#autorun_add.sh   /home/cnscn/iptables/iptablerules 3)创建成功，检查服务列表
#chkconfig --list [cnscn@MagicLinux ~]$ chkconfig --list
..
sshd              0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
iptablerules     0:关闭 1:关闭 2:关闭 3:启用 4:启用 5:启用 6:关闭
.... #Copy 脚本到/etc/init.d cp script_file /etc/init.d/ #添加服务到服务列表
chkconfig --add script_file #设置启动级别 chkconfig --level 3,4,5 script_file on ==================================================== 示例: #!/bin/sh
#
# memcached:    MemCached Daemon
#
# chkconfig:    - 90 25
# description: MemCached Daemon
# # Source function library.

        echo
} stop()
{
        echo -n $"Shutting down memcached: "
        killproc memcached         echo
} [ -f /usr/local/bin/memcached ] || exit 0 # See how we were called.
