监控mysql主从复制的shell脚本。
说明:
监控脚本在 rhel5 下测试正常,其它版本的linux 系统请自行测试,需要的一些准备工作可以查看这篇文章
代码:
复制代码 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
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
#done
for mail in $MAILS;do
echo "$HOST replication error" | mail -s "$HOST replication error" $mail
done
#flag
echo "replication error" >"${crondir}/log/$HOST.mysql"
#log
echo "$check_date $HOST mysql replicaton error" >> $log
