环境是Centos6.5 x86_64系统
Zabbix版本:3.0.4
Mysql Server 版本:5.6.29 二进制安装
zabbix_agentd.conf的配置文件如下:
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat /usr/local/zabbix/etc/zabbix_agentd.conf | grep -v '^#' | grep -v '^$'
LogFile=/tmp/zabbix_agentd.log
EnableRemoteCommands=1
Server=10.18.3.193
ListenPort=10050
ServerActive=10.18.3.193
Hostname=10.18.3.191
AllowRoot=1
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf
UnsafeUserParameters=1
#下面两行是自定义的key
UserParameter=mysql.slave,/usr/local/zabbix/share/zabbix/alertscripts/check_mysql_slave.sh | grep -c 'ok'
UserParameter=mysql.status[*],/usr/local/zabbix/share/zabbix/alertscripts/mysql_server_status.sh $1
查看mysql授权:
wKiom1i3or6yXIfoAAA3WVHaxd8949.png-wh_50
mysql授权需要密码才能访问,但是使用密码mysql会提示明文密码,就会有下面的提示:
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# sh check_mysql_slave.sh
Warning: Using a password on the command line interface can be insecure.
ok -slave is running
解决办法如下:
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat /etc/my.cnf | tail -4
[client]
user = root
host = localhost
password = 1qaz@WSX
再次运行脚本:
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# sh check_mysql_slave.sh
ok -slave is running
mysql主从监控脚本,脚本中去掉用户,密码直接使用命令。
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat check_mysql_slave.sh
#!/bin/bash
declare -a slave_is
slave_is=($(/data/mysql/bin/mysql -e "show slave status\G"|grep -E "Slave_IO_Running|Slave_SQL_Running:"|awk '{print $2}'))
if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ];then
echo "ok -slave is running"
exit 0
else
echo "down -slave is not running"
exit 2
fi
mysql_server_status脚本,这块上面my.cnf填写以后,使用mysqladmin也就不提示了:
[root@iZuf67iz9o3i4wixgtwybnZ alertscripts]# cat mysql_server_status.sh
#!/bin/bash
source /etc/profile
mysqladmin=`which mysqladmin`
case $1 in

在zabbix_server获取key值,或是查看zabbix_server.log文件都可以排错。
[root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]
ZBX_NOTSUPPORTED: Unsupported item key.
[root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]
/usr/local/zabbix/share/zabbix/alertscripts/mysql_server_status.sh: line 4: mysqladmin: command not found
[root@iZuf67iz9o3i4wixgtwybmZ bin]# ./zabbix_get -s 10.18.3.191 -k mysql.status[Uptime]

zabbix_agent.log可以看到已经获取到自定义的key:
wKiom1i3ojuQLV_2AAEobxWRPDI852.png-wh_50
添加自定义模板,模板名称随意给个和mysql相关的:
wKioL1i3o-7ivVBFAABlolKDSbw675.png-wh_50
创建应用集:
wKioL1i3pDnjLB2JAAA9LYgzWFE576.png-wh_50
添加监控项,一个key一个key添加,把脚本的key都添加进去。
wKioL1i3pIrS6cCUAAB3jZDOFlw111.png-wh_50
如下所示:
wKiom1i3pFexNKMDAAGE4D0rHXA177.png-wh_50
mysql 状态这块只做了图形查看,并没有做触发器,只做了主从的触发器,需要的可以自己添加:
wKiom1i3pPrBu-umAADKdeUVUl4065.png-wh_50
添加完成后可以添加一台mysql数据库查看下最新数据,是否成功了。
