为了方便管理bind，编写shell脚本，实现bind的start、stop、restart、status操作，并可以将脚本复制到/etc/rc.d/init.d/，添加以服务启动，并设置bind服务为开机启动。

脚本bind:

#!/bin/bash
    # bind 运行管理脚本，可以将该脚本复制到/etc/rc.d/init.d/，使用系统service维护
    # chkconfig: 345 35 75
    
    #启动用户
    BIND_USER=slim
    #chroot path
    CHROOT_PATH=/home/slim/chroot
    #bind install apth
    BIND_PATH=/home/slim/bind
    
    if [ `id -u` -ne 0 ]; then
            echo "ERROR:For bind to port 53,must run as root."
            exit 1
    fi
    case "$1" in
    start)
    if [ -x $BIND_PATH/sbin/named ];then
            $BIND_PATH/sbin/named -u $BIND_USER -t $CHROOT_PATH -c /etc/named.conf && echo "BIND Server is started."
    fi
    ;;
    stop)
            kill `cat $CHROOT_PATH/var/run/named.pid ` && echo "BIND Server is stopped."
    ;;
    restart)
            echo "Restart BIND server."
            $0 stop
            sleep 3
            $0 start
    ;;
    reload)
            $BIND_PATH/sbin/rndc -c $CHROOT_PATH/etc/rndc.conf reload
    ;;
    status)
            $BIND_PATH/sbin/rndc -c $CHROOT_PATH/etc/rndc.conf status
    ;;
    *)
            echo "Usage:$0 start | stop | restart |reload |status"
            exit 1
    ;;
    esac
    exit 0

添加执行权限：

chmod +x bind

复制脚本bind到cp bind /etc/rc.d/init.d/中使用service管理：

service bind start|stop|restart|reload|status

添加开机启动：

\#cd /etc/init.d/

\# chkconfig --add bind /\*将bind添加到chkconfig管辖之内

\# chkconfig  bind on   /\*启用这个服务

\# chkconfig --list  bind    /\*显示bind

chkconfig参数：

#chkconfig -h
