代码如下:

#监控mysql 主从复制

cat chk_mysql_rep.sh

#!/bin/bash

#

#script_name:chk_mysql_rep.sh

#check mysql replication

#

#ssh root@xen “/usr/local/mysql/bin/mysql -uroot -pdongnan -e show slave statusG -ss” | awk /Running:/ {print $2}

#Yes

#Yes

#

#variables

ssh=/usr/bin/ssh

sh_dir=/root/sh/

crondir=${sh_dir}crontab

source ${sh_dir}CONFIG

hosts=”$DB_SLAVE_HOSTS”

#main

#主循环遍历机器 www.jb51.net

for HOST in $hosts;do

log=$crondir/log/mysql_replication_error.log

key=$($ssh root@$HOST “/usr/local/mysql/bin/mysql -uroot -pdongnan -e show slave statusG -ss” | awk /Running:/ {printf $2})

    #无法连接的主机,跳过本次循环

test -z “$key” && continue

    #返回结果真

    if [ “$key” == “YesYes” ];then

        #flag真,解除报警

if [ -f “${crondir}/log/$HOST.mysql” ];then

            #sms

            #for mobile in $MOBILES;do

#echo “$HOST replication ok” | /usr/local/bin/gammu –sendsms TEXT “$mobile” -unicode

            #done

            #mail

            for mail in $MAILS;do

echo “$HOST replication ok” | mail -s “$HOST replication ok” $mail

            done

            #flag

            rm -f “${crondir}/log/$HOST.mysql”

        fi

    #返回结果假

    else  

check_date=$(date + %F %T)

#flag假，报警

        if [ ! -f “${crondir}/log/$HOST.mysql” ];then

            #sms www.jb51.net

            #for mobile in $MOBILES;do

#echo “$HOST replication error” | /usr/local/bin/gammu –sendsms TEXT “$mobile” -unicode

for mail in $MAILS;do

                echo “$HOST replication error” | mail -s “$HOST replication error” $mail

            done

            #flag
