在mac上虽然搭建好了PHP环境，但发现启动灰常麻烦，所以就自己写了一个shell脚本，错误之处，麻烦大家给予指出。

#!/bin/sh
userID=$(id -u);
apc=$(pgrep httpd | wc -l);
msql=$(pgrep mysqld | wc -l);
if [[ $userID == 0 ]]; then
	case "$1" in
		"0" )
		if [[ $msql -eq 0 && $apc -eq 0 ]]; then
			apachectl start
			echo "Starting apache ...OK";
			echo $(/usr/local/mysql/support-files/mysql.server start) >> null;
			echo "Starting MySQL ...OK";
		else
			if [[ $apc -ne 0 ]]; then
				echo "apache已运行。。。";
			fi
			if [[ $msql -ne 0 ]]; then
				echo "MySQL已运行。。。";
			fi
		fi
		;;
		"1" )
			if [[ $apc -ne 0 ]]; then
				apachectl stop
			fi
			if [[ $msql -ne 0 ]]; then
				/usr/local/mysql/support-files/mysql.server stop
			fi		
		;;
		*)
		echo "参数不正确,0为启动，1为关闭";
	esac
else
	echo "请以ROOT运行脚本！";
fi
