利用系统函数模拟实现nginx 系统脚本启动的特殊颜色专业效果/etc/init.d/nginxd {start/stop/restart/reload}利用if语句实现：
===========================================================
实现特殊颜色实现效果：
vim start_nginx.sh
[root@lamp01 scripts]# cat bqh_nginx_startup.sh
#!/bin/sh
. /etc/init.d/functions
if [ $# -ne 1 ]
then
echo "USAGE $0 {start|stop|restart}"
exit 1
fi
if [ "$1" == "start" ]
then
action "start nginx" /bin/true
elif [ "$1" == "stop" ]
then
action "stop nginx" /bin/true
elif [ "$1" == "restart" ]
then
action "restart nginx" /bin/true
else
echo "USAGE $0 {start|stop|restart}"
exit 1
fi
添加函数功能，实现上面的效果：
vim bqh_nginx_startup.sh
#!/bin/sh
. /etc/init.d/functions
start_nginx=/application/nginx/sbin/nginx
USAGE()
{
echo "USAGE $0 {start|stop|restart}"
}
if [ $# -ne 1 ]
then
echo "USAGE $0 {start|stop|restart}"
exit 1
fi
if [ "$1" == "start" ]
then
$start_nginx
action "start nginx" /bin/true
elif [ "$1" == "stop" ]
then
killall nginx
action "stop nginx" /bin/true elif [ "$1" == "restart" ]
then
pkill nginx
sleep 2
$start_nginx
action "restart nginx" /bin/true
else
echo "USAGE $0 {start|stop|restart}"
exit 1
fi
