mysql主从监控脚本含自动配置发Gmail邮件客户端

常用脚本备份

自动配置msmtp，使用mail发邮件 

#!/bin/bash 

SRC=/usr/local/src 

cd $SRC 

#install msmtp client 

# if your want support TLS/SSL,install openssl-devel 

# yum install -y openssl-devel  // 

wget http://nchc.dl.sourceforge.net/project/msmtp/msmtp/1.4.28/msmtp-1.4.28.tar.bz2 

tar xjf msmtp-1.4.28.tar.bz2 

cd msmtp-1.4.28 

./configure --prefix=/usr/local/msmtp && make && make install  

cd /usr/local/msmtp/ 

mkdir etc

wget -O /usr/local/msmtp/etc/gmail.crt http://www.geotrust.com/resources/extended-validation-ssl/certs/Equifax%20Secure%20Certificate%20Authority.crt 

ln -s /usr/local/msmtp/bin/msmtp /usr/bin/ 

echo "set sendmail=/usr/bin/msmtp" >> /etc/mail.rc  

脚本2 <监控mysql服务器主从,来自抚琴煮酒> 

#!/bin/bash  

#check MySQL_Slave Status 

#crontab time every 10 min

test -e /data0/mysql/check_mysql_slave.log || touch /data0/mysql/check_mysql_slave.log  

chown mysql.mysql /data0/mysql/check_mysql_slave.log  

MYSQLPORT=`netstat -na|grep "LISTEN"|grep "3306"|awk -F[:" "]+ '{print $5}'` 

MYSQLIP=`ifconfig eth0|grep "inet addr" | awk -F[:" "]+ '{print $4}'` 

STATUS=$(/usr/local/mysql/bin/mysql -uadmin -ppassword -S /tmp/mysql.sock -e "show slave status\G" | grep -i "running") 

IO_env=`echo $STATUS | grep IO | awk  ' {print $2}'` 

SQL_env=`echo $STATUS | grep SQL | awk  '{print $2}'` 

DATA=`date +"%y-%m-%d %H:%M:%S"` 

if [ "$MYSQLPORT" == "3306" ] 

then 

    echo "mysql is running" 

else 

    mail -s "ERROR!server: $MYSQLIP mysql is down" start@gmail.com  -c user1@gmail.com -c user2@gmail.com -c user3@gmail.com 

fi 

if [ "$IO_env" = "Yes" -a "$SQL_env" = "Yes" ] 

then 

    echo "Slave is running!" 

else 

    echo "####### $DATA #########">> /data0/mysql/check_mysql_slave.log 

    echo "Slave is not running!" >>  /data0/mysql/check_mysql_slave.log 

    echo "Slave is not running!" | mail -s "ERROR! $MYSQLIP MySQL Slave is not running" start@gmail.com -c user1@gmail.com -c user2@gmail.com -c user3@gmail.com 

fi 

 最近因实际需求，对脚本做了以下更改，添加了DNS的监控。与上一个有些区别的就是，经一发邮件出来。而不是有一个错就发会邮件出来。

#!/bin/bash  -x 

#check MySQL_Slave Status and check dns status 

#crontab time 00:10 

test -e /data0/mysql/check_mysql_slave.log || touch /data0/mysql/check_mysql_slave.log

STATUS=$(/usr/local/mysql/bin/mysql -uadmin -ppassword -S /tmp/mysql.sock -e "show slave status\G" | grep -i "running")
