ZABBIX 3.X加载percona mysql插件来监控mysql5.6的详细实现过程
安装部署zabbix见上一篇文章《ZABBIX企业级监控安装部署》
http://blog.csdn.net/crpp0902/article/details/77978405
部署完zabbix,自带的对于mysql的监控脚本远远不能满足DBA日常监控的需要，percona就有这个详细监控的模版以及脚本，刚好能用于DBA日常的监控。
1、需要安装php脚本运行环境
percona监控zabbix的脚本使用php写的，所以需要准备好php运行环境：
yum install -yphp php-mysql 2、安装 percona-zabbix-templates
yum install https://www.percona.com/downloads/percona-monitoring-plugins/1.1.6/percona-zabbix-templates-1.1.6-1.noarch.rpm安装完，我们介绍几个重要文件：
[root@slave1 zabbix_agentd.d]# cd /var/lib/zabbix/percona/
[root@slave1 percona]# ls
scripts templates
[root@slave1 percona]#
[root@slave1 scripts]# cd ../templates/
[root@slave1 templates]# ls -alt
total 292
drwxr-xr-x. 2 root root 4096 Sep 14 01:33 .
drwxr-xr-x. 4 root root 4096 Sep 13 21:52 ..
-rw-r--r--. 1 root root 18866 Jan 11 2016 userparameter_percona_mysql.conf
-rw-r--r--. 1 root root 269258 Jan 11 2016 zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.6.xml
[root@slave1 templates]# ls -alt ../scripts/
total 72
drwxr-xr-x. 2 root root 4096 Sep 14 01:40 .
-rwxr-xr-x. 1 root root 1259 Sep 14 01:40 get_mysql_stats_wrapper.sh
-rwxr-xr-x. 1 root root 59634 Sep 13 22:23 ss_get_mysql_stats.php
*scripts目录下get_mysql_stats_wrapper.sh脚本是监控获取MySQL状态的，ss_get_mysql_stats.php文件是配置连接数据库用户名密码的。用shell来调用PHP。
* templates目录下conf文件是要放在agent端/etc/zabbix/zabbix_agentd.d/下面的，用于定义监控的items，XML文件是模版文件（这个模板目前还不支持zabbix 3,需要进行修改）
3、导入模板xml文件到zabbix server
报错：Invalid tag"/zabbix_export/date": "YYYY-MM-DDThh:mm:ssZ" is expected.
解决：这个模板还不支持zabbix，需要修改xml模板文件，网上有对应ZABBIX 3的模板导入即可。
4、修改相关脚本：
vim get_mysql_stats_wrapper.sh
修改：
RES=`HOME=~zabbix mysql -e 'SHOW SLAVESTATUS\G' | egrep '(Slave_IO_Running|Slave_SQL_Running):' | awk -F: '{print$2}' | tr '\n
为：
RES=`HOME=~/usr/bin/mysql -e 'SHOW SLAVE STATUS\G' | egrep'(Slave_IO_Running|Slave_SQL_Running):' | awk -F: '{print $2}' | tr '\n' ','`
修改
HOST=localhost
为：
HOST=192.168.174.133
vim ss_get_mysql_stats.php
$mysql_user = 'zabbix';
$mysql_pass = '123456';
$mysql_port = 3306;
cp/var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf/etc/zabbix/zabbix_agentd.d/userparameter_percona_mysql.conf
测试监控项：
[root@slave1 templates]# /usr/bin/php -q /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php--host localhost --items gg
ERROR: Access denied for user'zabbix'@'localhost' (using password: YES)
[root@slave1templates]# /usr/bin/php -q/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php --host 192.168.174.133--items gg
gg:285、应用percona模板到监控：
查看相应监控数据图表：
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
22
[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
