检测nginx、php-fpm、mysql进程的脚本

用途：检测php-fpm、nginx、mysql进程是否正常，如果不正常，则重启服务！
#!/bin/bash
logpath=/home/scripts
url="**b.g**yz.com/index.php" 
status=$(/usr/bin/curl -s --head "$url" | awk '/HTTP/ {print $2}')
if [ "$status" != "200" ] ;  then
echo `date`                  > ${logpath}/nginxphpmysqlcheck.log 2>&1
/etc/init.d/php-fpm restart >> ${logpath}/nginxphpmysqlcheck.log 2>&1
/etc/init.d/nginx   restart >> ${logpath}/nginxphpmysqlcheck.log 2>&1
fi




/data/mysql/bin/mysqladmin -uroot -p*** ping > ${logpath}/mysqlstatus.txt 2>&1


cat ${logpath}/mysqlstatus.txt | grep failed > ${logpath}/mysqlstatusfail.txt
if [ -s ${logpath}/mysqlstatusfail.txt  ] ; then
echo "I will restart mysqld" >>${logpath}/nginxphpmysqlcheck.log  2>&1
service mysqld start
fi
工作中的脚本，备份只用！


这个脚本有时候有问题，在负载高的时候有问题的，我修改为：
[root@loldb scripts]# cat nginxphpmysqlcheck.sh 
#!/bin/bash
logpath=/home/scripts
url="***b.g****z.com/index.php" 
status=$(/usr/bin/curl -s --head "$url" | awk '/HTTP/ {print $2}')
if [ "$status" != "200" ] ;  then
echo `date`                  > ${logpath}/nginxphpmysqlcheck.log 2>&1
killall -9 php-fpm   ##如果不使用这个不能瞬间释放掉9000端口，再次启动的时候会提示9000端口在占用，造成不能成功重启
killall -9 nginx
sleep 30
/etc/init.d/php-fpm start >> ${logpath}/nginxphpmysqlcheck.log 2>&1
/etc/init.d/nginx   start >> ${logpath}/nginxphpmysqlcheck.log 2>&1
fi


/data/mysql/bin/mysqladmin -uroot -pkuutown1601 ping > ${logpath}/mysqlstatus.txt 2>&1


cat ${logpath}/mysqlstatus.txt | grep failed > ${logpath}/mysqlstatusfail.txt
if [ -s ${logpath}/mysqlstatusfail.txt  ] ; then
echo "I will restart mysqld" >>${logpath}/nginxphpmysqlcheck.log  2>&1
service mysqld start
fi
