Ubuntu下Zabbix结合percona监控mysql数据 1、percona插件安装： 2、编辑配置文件 4、重启zabbix客户端 5、导入mysql的监控模板 6、导入出错 7、关联模板Template Percona MySQL Server 8、查看监控图像，出数据如图4、图5所示： 9、碰到问题：
按道理来说zabbix就自带的MySQL插件来监控mysql数据库，但是你会发现，自带的mysql监控项是很少的，根本满足不了公司的需求。
由于它本身自带的模板太过简单了，所以需要做更详细的监控，而percona就提供了这个详细监控的模版以及脚本，解决了监控不全面的问题。
percona插件是安装在zabbix-agent端的
首先需要下载php依赖：
ubuntu@ubuntu:~$ apt-get install php
1、官网下载percona包
https://www.percona.com/downloads/percona-monitoring-plugins/Version: percona的版本
Software：linux server的版本
Download All Packages Together： 一起下载所有包
Download Packages Separately： 单独下载某个包
这里我们选择下载最后一个包-percona-zabbix-templates-1.1.7-1.xenial_all.ded
2、命令下载
ubuntu@ubuntu:~$ wget https://www.percona.com/downloads/percona-monitoring-plugins/1.1.7/binary/debian/xenial/x86_64/percona-zabbix-templates_1.1.7-1.xenial_all.deb
3、安装percona包
ubuntu@ubuntu:~$ sudo dpkg -i percona-zabbix-templates_1.1.7-1.xenial_all.deb
ubuntu@ubuntu:~$ cd /var/lib/zabbix/percona/templates && ll
total 292
drwxr-xr-x 2 root root 4096 Mar 25 14:19 ./
drwxr-xr-x 4 root root 4096 Mar 15 11:39 ../
-rw-r--r-- 1 root root 18866 Dec 8 2016 userparameter_percona_mysql.conf
-rw-r--r-- 1 root root 269258 Dec 8 2016 zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.7.xml
2、编辑配置文件
1、添加模板文件路径
ubuntu@ubuntu:~$ sudo mv /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix_agentd.conf.d/
2、修改MySQL的执行命令文件，更改mysql的用户与密码：
ubuntu@ubuntu:~$ sudo vim /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh
RES=`HOME=~ /usr/bin/mysql -uroot -pzabbix -e 'SHOW SLAVE STATUSG' | egrep '(Slave_IO_Running|Slave_SQL_Running):' | awk -F: '{print $2}' | tr '
' ','`
mysql -u用户名 -p密码，这里根据自己实际情况修改
3、修改 ss_get_mysql_stats.php文件
ubuntu@ubuntu:~$ sudo vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
$mysql_user = 'root';
$mysql_pass = 'zabbix';
4、重启zabbix客户端
[root@node2 templates]# /etc/init.d/zabbix_agentd restart
5、导入mysql的监控模板
模板需要先导入桌面
ubuntu@ubuntu:~$ sudo sz /var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.7.xml
6、导入出错
出现“标签无效 "/zabbix_export/date": "YYYY-MM-DDThh:mm:ssZ" 预计”，如图2所示：
图2
解决方法：百度了一下说将zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.7.xml导入zabbix2.4版本中再导出。之后将新的导出xml导入到3.2中问题解决。
7、关联模板Template Percona MySQL Server
8、查看监控图像，出数据如图4、图5所示：
9、碰到问题：
55392:20170914:014811.374 item "SLAVE1:MySQL.State-none" became not supported: Value "rm: cannot remove `/tmp/192.168.174.133-mysql_cacti_stats.txt': Operation not permitted
21" of type "string" is not suitable for value type "Numeric (float)"
55392:20170914:014813.403 item "SLAVE1:MySQL.State-other" became not supported: Value "rm: cannot remove `/tmp/192.168.174.133-mysql_cacti_stats.txt': Operation not permitted
0" of type "string" is not suitable for value type "Numeric (float)"
执行测试发现发现是文件权限不对：
[root@slave1 zabbix]# zabbix_get -s 192.168.174.133 -p 10050 -k "MySQL.Threads-connected"
rm: cannot remove `/tmp/192.168.174.133-mysql_cacti_stats.txt': Operation not permitted
[root@slave1 zabbix]# ls -alt /tmp/192.168.174.133-mysql_cacti_stats.txt
-rw-r--r--. 1 root root 1422 Sep 14 01:41 /tmp/192.168.174.133-mysql_cacti_stats.txt
修改权限后测试正常：
[root@slave1 zabbix]# chown zabbix:zabbix /tmp/192.168.174.133-mysql_cacti_stats.txt
[root@slave1 zabbix]# zabbix_get -s 192.168.174.133 -p 10050 -k "MySQL.Threads-connected"
22
[root@slave1 zabbix]# zabbix_get -s 192.168.174.133 -p 10050 -k "MySQL.Key-read-requests"
152
查看日志也正常：
[root@slave1 zabbix]# tail -f zabbix_server.log
