服务进程自启动脚本，实现每分钟检查服务运行状态

由于程序真是环境不是由自己运维的，真是负责运维的人员并不了解软件，所以增加一份自启动脚本

脚本原理：利用linux系统的crontab定时任务，每一分钟检查一次系统进程是否存在，若不存在则调用启动命令并记录日志

#!/bin/sh
#启动日志存放路径

startPath=/data/start.log

#检查启动日志是否存在
if [ ! -f $startPath ];then
touch $startPath
chown bfc:bfc $startPath
curDate=`date +%s`
curTime=`date -d @$curDate "+%Y-%m-%d %H:%M:%S"`
echo $curTime: logstart >> $startPath
else
chown bfc:bfc $startPath
fi

#检查mysql是否启动
pid=`ps -ef|grep mysql | grep -v grep |awk '{print $2}'`
if [ "$pid" == "" ];then
service mysql restart
sleep 5
pid=`ps -ef|grep mysql | grep  -v grep | awk '{print $2}'`
if [ "$pid" = "" ];then
curDate=`date +%s`
curTime=`date -d @$curDate "+%Y-%m-%d %H:%M:%S"`
echo "$curTime: mysql start faild!!!" >> $startPath
else
curDate=`date +%s`
curTime=`date -d @$curDate "+%Y-%m-%d %H:%M:%S"`
echo "$curTime: mysql start success." >> $startPath
fi
else
curDate=`date +%s`
curTime=`date -d @$curDate "+%Y-%m-%d %H:%M:%S"`
echo "$curTime: mysql process already exists." >> $startPath
fi

pid=`jps -l | grep org.elasticsearch.bootstrap.Elasticsearch | awk '{print $1}'`
