求linux下编译完程序所写启动脚本的注释????

print

18.创建启动脚本
# vi /etc/rc.d/init.d/named
#!/bin/sh
#
# named This shell script takes care of starting and stopping
# named (BIND DNS server).
#
# chkconfig: 345 55 45
# description: named (BIND) is a Domain Name Server (DNS) \
# that is used to resolve host names to IP addresses.
# probe: true

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0

[ -f /usr/sbin/named ] || exit 0

[ -f /etc/named.conf ] || exit 0

# See how we were called.
case "$1" in
start)
# Start daemons.
echo -n "Starting named: "
daemon named
echo
touch /var/lock/subsys/named
;;
stop)
# Stop daemons.
echo -n "Shutting down named: "
killproc named
rm -f /var/lock/subsys/named
echo
;;
status)
/usr/sbin/rndc status
exit $?
;;
restart)
$0 stop
$0 start
exit $?
;;
reload)
/usr/sbin/rndc reload
exit $?
;;
probe)
# named knows how to reload intelligently; we don't want linuxconf
# to offer to restart every time
/usr/sbin/rndc reload >/dev/null 2>&1 || echo start
exit 0
;;

*)
echo "Usage: named {start|stop|status|restart}"
exit 1
esac

exit 0
19.将/etc/rc.d/init.d/named变成可执行文件。
# chmod 755 /etc/rc.d/init.d/named
20.创建启动脚本symbollink
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc0.d/K45named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc1.d/K45named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc2.d/K45named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc3.d/S55named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc4.d/S55named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc5.d/S55named
# ln -s /etc/rc.d/init.d/named /etc/rc.d/rc6.d/K45named
21.启动bind9
# /etc/rc.d/init.d/named start
停止bind9
# /etc/rc.d/init.d/named stop
查看状态
# /etc/rc.d/init.d/named status


上面是一段配置dns的教程,能否麻烦各位就/etc/rc.d/init.d/named文件的内容给点注释???最好是讲讲原理

我成功安装并配置好bind9,可写启动脚本老不行,是按照上面的教程修改的...

print

感谢斑主的解答,下面是我的启动脚本,可启动NAMED出现如下错误

[root@dns init.d]# /etc/rc.d/init.d/named start
Starting named: execvp: 没有那个文件或目录
[失败]

我注释掉daemon named就不会出现错误提示,可named根本没启动,

/etc/rc.d/init.d/named 文件内容

#!/bin/sh
#
# named This shell script takes care of starting and stopping
# named (BIND DNS server).
#
# chkconfig: 345 55 45
# description: named (BIND) is a Domain Name Server (DNS) \
# that is used to resolve host names to IP addresses.
# probe: true
# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
#echo -n "ssss"

[ -f /soft/bind/sbin/named ] || exit 0

#echo -n "aaa"

[ -f /soft/bind/etc/named.conf ] || exit 0

#echo -n "sssssaaa"

# See how we were called.
case "$1" in
start)
# Start daemons.
echo -n "Starting named: "
daemon named
echo
touch /soft/bind/temp/named
;;
stop)
# Stop daemons.
echo -n "Shutting down named: "
killproc named
rm -f /soft/bind/temp/named
echo
;;
status)
/soft/bind/sbin/rndc status
exit $?
;;
restart)
$0 stop
$0 start
exit $?
;;
reload)
/soft/bind/sbin/rndc reload
exit $?
;;
probe)
# named knows how to reload intelligently; we don't want linuxconf
# to offer to restart every time
/soft/bind/sbin/rndc reload >/dev/null 2>&1 || echo start
exit 0
;;

*)
echo "Usage: named {start|stop|status|restart}"
exit 1
esac

exit 0

脚本找不到execvp
如果不想看到ＳＵＣＣＥＳＳ或ＦＡＩＬＤ
daemon name改成named&

怎么解决？？

如果不想看到ＳＵＣＣＥＳＳ或ＦＡＩＬＤ
daemon name改成named&

daemon named 和 named& 有什么区别？？？

斑竹可别嫌我等的问题问得比较菜。。

把execvp所在的目录加到环境变量PATH中

没区别，daemon是脚本写的启动函数，加了些了显示和文件检查在里面
最本质的一句还是named&
