部署完zabbix,自帶的對於mysql的監控指令碼遠遠不能滿足DBA日常監控的需要，percona就有這個詳細監控的模版以及指令碼，剛好能用於DBA日常的監控。

1、需要安裝php指令碼執行環境

percona監控zabbix的指令碼使用php寫的，所以需要準備好php執行環境：

yum install -yphp php-mysql 

yum install https://www.percona.com/downloads/percona-monitoring-plugins/1.1.6/percona-zabbix-templates-1.1.6-1.noarch.rpm
 

安裝完，我們介紹幾個重要檔案：

[[email protected] zabbix_agentd.d]# cd /var/lib/zabbix/percona/
[[email protected] percona]# ls
scripts  templates
[[email protected] percona]#
[[email protected] scripts]# cd ../templates/
[[email protected] 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
[
 
[email protected] 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目錄下get_mysql_stats_wrapper.sh指令碼是監控獲取MySQL狀態的，ss_get_mysql_stats.php檔案是配置連線資料庫使用者名稱密碼的。用shell來呼叫PHP。

* templates目錄下conf檔案是要放在agent端/etc/zabbix/zabbix_agentd.d/下面的，用於定義監控的items，XML檔案是模版檔案（這個模板目前還不支援zabbix 3,需要進行修改）

3、匯入模板xml檔案到zabbix server

報錯：Invalid tag"/zabbix_export/date": "YYYY-MM-DDThh:mm:ssZ" is expected.

解決：這個模板還不支援zabbix，需要修改xml模板檔案，網上有對應ZABBIX 3的模板匯入即可。

4、修改相關指令碼：

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
為：
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
為：
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

測試監控項：
[[email protected] 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)

 [[email protected]]#  /usr/bin/php -q/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php --host 192.168.174.133--items gg

gg:28

檢視相應監控資料圖表：

碰到問題：

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)"

執行測試發現發現是檔案許可權不對：

[[email protected] 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

[[email protected] 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

修改許可權後測試正常：

[[email protected] zabbix]# chown zabbix:zabbix /tmp/192.168.174.133-mysql_cacti_stats.txt

[[email protected] zabbix]# zabbix_get -s 192.168.174.133 -p 10050 -k  "MySQL.Threads-connected"
22
[[email protected] zabbix]# zabbix_get -s 192.168.174.133 -p 10050 -k  "MySQL.Key-read-requests"
152

檢視日誌也正常：
[[email protected] zabbix]# tail -f zabbix_server.log
