Linux服务器监听mysql及redis是否启动，如果没有启动则自动启动

#!/bin/bash
result=`netstat -lntup |grep 3306|wc -l`
if [[ $result = "0" ]] 
then
    /etc/init.d/mysqld start
else
    echo "Mysql is running"
fi
result1=netstat -lntup |grep 6379|wc -l
if [[ $result1 = "0" ]] 
then
    /etc/init.d/redis start
else
    echo "Redis is running"
fi
