本节内容:
监控的shell脚本。
说明:
监控脚本在 rhel5 下测试正常,其它版本的请自行测试。
代码:
-
#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 status\G' -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.jbxue.com
-
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 status\G' -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
-

-
#返回结果假
-
else
-
check_date=$(date '+ %F %T')
-
#flag假,报警
-
