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

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
