使用Zabbix監控Mysql(FromDual)

1、安裝Perl模塊

# perl -MCPAN -e shell

cpan> install File::Which

cpan> install Bundle::LWP

cpan> install Digest::SHA1

cpan> install DBI

cpan> install DBD::mysql

cpan> install Time::HiRes

cpan> install Crypt::SSLeay

 

在安裝DBD::mysql時，提示安裝成功，但運行下面的perl腳本時，提示找不到DBD::mysql，這樣的話使用源碼安裝DBD::mysql；

 

2、在zabbix server端導入監控模板

導入相應須要的模板：

Template_FromDual.MySQL.mpm.xml  -->(必須)

Template_FromDual.MySQL.server.xml  -->監控與數據庫相關的Linux服務器性能模板

Template_FromDual.MySQL.process.xml -->監控各類Linux進程

Template_FromDual.MySQL.mysql.xml   -->監控Mysql的經常使用狀態變量

Template_FromDual.MySQL.myisam.xml  -->監控Myisam存儲引擎狀態變量

Template_FromDual.MySQL.innodb.xml  -->監控Innodb存儲引擎狀態變量

Template_FromDual.MySQL.master.xml  -->監控Mysql Master狀態

Template_FromDual.MySQL.slave.xml   -->監控Mysql Slave狀態

 

3、在Mysql數據庫服務器上上傳監控腳本

cd /usr/local

tar xvf mysql_performance_monitor_agent-0.9.tar.gz

mv mysql_performance_monitor_agent-0.9/ mysql_performance_monitor

cd mysql_performance_monitor/etc

cp FromDualMySQLagent.conf.template FromDualMySQLagent.conf

 

4、修改監控腳本配置文件

# cat FromDualMySQLagent.conf

[default]

# Type of section:

# mysqld for a normal MySQL database

# ndbd   for a MySQL cluster

Type         = mysqld

 

# Debug levels are:

# 1 is logging only errors

# 2 is logging errors and warnings (this is the default)

# 3 logs some informations messages as well

# 4 logs everything (for debugging purposes only)

 

Debug         = 2

#執行日誌文件路徑，須要zabbix用戶可寫權限

LogFile       = /data/log/zabbix/FromDualMySQLagent.log

# Directory where the Cache files should be written to:

CacheFileBase = /tmp/FromDualAgentCache

 

# Information for MySQL connections:

#須要在Mysql中進行受權

Username     = mpm

Password     = password

MysqlHost    = 127.0.0.1

MysqlPort    = 3306

 

# Zabbix Server IP address

ZabbixServer = 192.168.100.241

 

# If section is disabled

Disabled     = false

 

# Possible modules for databases are:

# process mysql myisam aria innodb pbxt ndb master slave drbd galera memcache

# Possible modules for servers are:

# mpm server

# Usual modules are

Modules      = process mysql myisam innodb

 

# Special parameter which is used for module ndb and process

ClusterLog   = /data/log/zabbix/ndb_1_cluster.log

#Mysql的PID文件，須要zabbix用戶可讀權限

PidFile      = /data/mysql/data/b2b-tj-demo166.bw.mg.pid

 

#下面的主機名須要跟Zabbix Server裏面定義的主機名一致

[125.39.195.166]

Type         = mysqld

Modules      = mpm server process mysql myisam innodb

 

5、修改Zabbix Agent配置文件

#/etc/zabbix/zabbix_agentd.conf

UserParameter=FromDual.MySQL.check,/usr/local/mysql_performance_monitor/FromDualMySQLagent.pl /usr/local/mysql_performance_monitor/etc/FromDualMySQLagent.conf

 

 

修改FromDualMySQLagent.pl腳本里面的zabbix_sender路徑：

# This is needed to find zabbix_sender!

$ENV{PATH} .= $ENV{PATH} . ':/usr/local/zabbix/bin';  #將/usr/local/bin修改成/usr/local/zabbix/bin(爲zabbix_sender路徑)

 

6、Mysql數據庫受權、重啓Zabbix客戶端

CREATE USER 'mpm'@'127.0.0.1' IDENTIFIED BY 'mpmsecret';

GRANT PROCESS ON *.* TO 'mpm'@'127.0.0.1';

GRANT REPLICATION CLIENT ON *.* TO 'mpm'@'127.0.0.1';

 

/etc/init.d/zabbix_agentd restart

 

查看日誌或Zabbix Server上的LastData數據檢查是否能夠正常接收到數據：

tail -f /data/log/zabbix/FromDualMySQLagent.log
