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:

.sh |
grep

'ok'
UserParameter=mysql.status[*],
/usr/local/zabbix/share/zabbix/alertscripts/mysql_server_status
.sh $1

查看mysql授权:
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:
1
2
|
[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。

then

在zabbix_server获取key值,或是查看zabbix_server.log文件都可以排错。

zabbix_agent.log可以看到已经获取到自定义的key:
添加自定义模板,模板名称随意给个和mysql相关的:
创建应用集:
添加监控项,一个key一个key添加,把脚本的key都添加进去。
如下所示:
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:
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。
查看图形监控数据:
