部署zabbix监控mysql (三) MPM插件介绍和部署

MPM插件部署

1.安装MPM依赖的相关perl模块

安装mpm需要的相关依赖包：[保险起见，agent端也安装下面的依赖包]

# yum -y install perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay

# yum -y install perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay

# yum -y install perl-CPAN.x86_64

# yum -y install which.x86_64

# yum -y install perl-LWP-Authen-Negotiate.noarch

# yum -y install perl-Digest-SHA1.x86_64

# yum -y install perl-Class-DBI-mysql.noarch

# yum -y install perl-Time-HiRes.x86_64

# yum -y install perl-Crypt-SSLeay.x86_64

下载MPM并解压：

[[email protected] zabbix]# wget http://www.shinguz.ch/download/mysql_performance_monitor-latest.tar.gz

[[email protected] zabbix]# tar xf mysql_performance_monitor-latest.tar.gz

[[email protected] zabbix]# ls -lrt

mysql_performance_monitor_agent-0.9.1.tar.gz

mysql_performance_monitor_templates-0.9.1.tar.gz

2.zabbix web 端导入MPM模版

在Zabbix Web UI导入监控所需的模板(“Configuration”->”Templates”->”Import”):

具体模板文件用途如下：

Template_FromDual.MySQL.ndb.xml              # 监控mysql cluster

Template_FromDual.MySQL.security.xml

Template_FromDual.MySQL.innodb.xml      # 监控innodb存储引擎状态变量

Template_FromDual.MySQL.mpm.xml         # 监控mpm agent本身，这个必须导入

Template_FromDual.MySQL.myisam.xml    # 监控myisam存储引擎状态变量

Template_FromDual.MySQL.mysql.xml       # 监控mysql 常用状态变量

Template_FromDual.MySQL.aria.xml             # 监控aria存储引擎的状态变量

Template_FromDual.MySQL.galera.xml          # 监控 mysql galera cluster

Template_FromDual.MySQL.slave.xml        # 监控mysql主从复制中的slave的状态

Template_FromDual.MySQL.server.xml      # 监控linux系统跟数据库使用相关的附加项

Template_FromDual.MySQL.master.xml     # 监控mysql主从复制的master的状态

Template_FromDual.MySQL.drbd.xml            # 监控drbd 设备的状态信息

Template_FromDual.MySQL.pbxt.xml             # 监控pbxt存储引擎状态变量

Template_FromDual.MySQL.process.xml        # 监控各种linux进程(比如：mysqld，ndbd)

3．安装MPM并且配置MPM Agent 的zabbix Keys，以实现zabbix挂接MPM

安装MPM Agent

在客户端[mysql 数据库服务器端] 安装mysql_performance_monitor_agent

[[email protected] ~]# tar xf mysql_performance_monitor_agent-0.9.1.tar.gz

[[email protected] ~]# mv mysql_performance_monitor_agent-0.9.1 /usr/local/mysql_performance_monitor_agent

# 修改 FromDualMySQLagent.pl 文件，指定zabbix_sender的位置

[[email protected] ~]# cd /usr/local/mysql_performance_monitor_agent

# sed -i "[email protected]/usr/local/[email protected]/usr/local/zabbix/[email protected]" FromDualMySQLagent.pl

将mpm Agent 的keys信息加入到zabbix_agentd的配置目录中

这个参数配置文件，是自己新建的

# cd /usr/local/zabbix/etc/zabbix_agent.conf.d/

# vim FromDual_MySQL_monitoring.conf

# cat  FromDual_MySQL_monitoring.conf

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

4.MPM Agent 配置

创建MPM的Mysql监控用户

mysql> create user ‘mpm‘@‘127.0.0.1‘ identified by "123456";

Query OK, 0 rows affected (0.00 sec)

mysql> grant process,replication client on *.* to ‘mpm‘@‘127.0.0.1‘;

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> grant process,replication client on *.* to ‘mpm‘@‘localhost‘ identified by "123456";

Query OK, 0 rows affected (0.00 sec)

配置 MPM Agent ：

[[email protected] ~]# cd /usr/local/mysql_performance_monitor_agent/etc/

[[email protected] etc]# cp FromDualMySQLagent.conf.template FromDualMySQLagent.conf

[[email protected] etc]# mkdir -p /var/log/zabbix

[[email protected] etc]# mkdir -p /var/log/zabbix/cache

[[email protected] etc]# touch /var/log/zabbix/FromDualMySQLagent.log

[[email protected] etc]# chown -R zabbix:zabbix /var/log/zabbix

[[email protected] etc]# ll /data/3306/mysql.pid

-rw-rw---- 1 mysql mysql 5 May  6 16:36 /data/3306/mysql.pid

[[email protected] etc]# chmod o+r /data/3306/mysql.pid

[[email protected] etc]# vim FromDualMySQLagent.conf

[default]

Type = mysqld

Debug = 2

#执行日志文件路径，需要zabbix用户可写权限

LogFile       = /var/log/zabbix/FromDualMySQLagent.log

CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache

#需要在本机的Mysql中进行授权(需要什么权限？process,replication client)

Username = mpm

Password = 123456

MysqlHost = 127.0.0.1

MysqlPort = 3306

ZabbixServer = 192.168.1.214

Disabled = false

Modules = process mysql myisam innodb

#ClusterLog   = /var/lib/mysql-cluster/ndb_1_cluster.log

# Mysql的PID文件，需要zabbix用户可读权限

PidFile      = /data/3306/mysql.pid

# 下面这个不能注掉也不能改section名称，探测本机的mpm是否可用

[db_server]

Type         = mysqld

Modules      = mpm server

#下面的主机名需要跟Zabbix Server里面定义的主机名一致，名称随意起

[hostname1]

Type = mysqld

#这些模块必须在mysql数据库上已经实现了功能，如主从，如果没有配置主从，而添加了master模板，在执行过程中就会报错

Type         = mysqld

MysqlPort    = 3306

Modules = mpm server process mysql myisam innodb master

PidFile      = /data/3306/mysql.pid

Debug        = 1

[[email protected] etc]# cat  FromDualMySQLagent.conf |egrep -v "^#|^$"

[default]

Type         = mysqld

Debug         = 2

LogFile       = /var/log/zabbix/FromDualMySQLagent.log

CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache

Username     = mpm

Password     = 123456

MysqlHost    = 127.0.0.1

MysqlPort    = 3306

ZabbixServer = 192.168.1.214

Disabled     = false

Modules      = process mysql myisam innodb

ClusterLog   = /var/lib/mysql-cluster/ndb_1_cluster.log

PidFile      = /data/3306/mysql.pid

[db_server]

Type         = mysqld

Modules      = mpm server

[mysqld_192.168.1.212]          # This MUST match Hostname in Zabbix!

Type         = mysqld

PidFile      = /data/3306/mysql.pid

Debug        = 1

检查MPM插件工作状况：

[[email protected] etc]# /usr/local/mysql_performance_monitor_agent/FromDualMySQLagent.pl /usr/local/mysql_performance_monitor_agent/etc/FromDualMySQLagent.conf

1

[[email protected] etc]#

# 返回值为1：表示MPM插件正常，重启zabbix_agent，加载mpm插件

[[email protected] etc]# /etc/init.d/zabbix_agentd restart

Stopping Zabbix Agent:                                     [  OK  ]

Starting Zabbix Agent:                                     [  OK  ]

[[email protected] etc]#

Zabbix web 端操作

创建监控数据库组

创建监控主机

填写相关主机信息

添加模版

Zabbix Agent 出现错误

[[email protected] ~]# tail -f /usr/local/zabbix/logs/zabbix_agentd.log

1.查看zabbix_agentd.conf文件中的Hostname

[[email protected] etc]# grep Hostname /usr/local/zabbix/etc/zabbix_agentd.conf

Hostname=mysqld_192.168.1.212

2.在zabbix web页面Monitoring->Configuration->Hosts 页面更改Host name和zabbix_agentd.conf里面的Hostname一样。

3.重新启动zabbix-agent服务

[[email protected] etc]# /etc/init.d/zabbix_agentd restart

Stopping Zabbix Agent:                                     [  OK  ]

Starting Zabbix Agent:                                     [  OK  ]

[[email protected] etc]#

没解决还是这个错误：

17486:20160510:130427.528 no active checks on server [192.168.1.214:10051]: host [mysqld_192.168.1.212] not found

排除错误：

Zabbixserver是zabbix-3.0.2.tar.gz，zabbix web是zabbix-2.4.8.tar.gz，所以重新安装下zabbix server 为zabbix-2.4.8.tar.gz。

步骤没有问题，版本的问题。

解决下这个问题：

# egrep-v "^#|^$" /usr/local/zabbix/etc/zabbix_agentd.conf

PidFile=/tmp/zabbix_agentd.pid

LogFile=/tmp/zabbix_agentd.log

Server=127.0.0.1

ListenPort=10050

ServerActive=127.0.0.1

Hostname=Zabbixserver

# cdzabbix-2.4.8

# cpmisc/init.d/fedora/core5/zabbix_agentd /etc/init.d/

# vim/etc/init.d/zabbix_agentd

prog="ZabbixAgent"

ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_agentd"

CONF_FILE="/usr/local/zabbix/etc/zabbix_agentd.conf"

start(){

…

daemon $ZABBIX_BIN -c $CONF_FILE

…

｝

[[email protected]_serverzabbix-2.4.8]# /etc/init.d/zabbix_agentd restart

停止 Zabbix Agent：                                        [确定]

正在启动 Zabbix Agent：                                    [确定]

[[email protected]_serverzabbix-2.4.8]#

搞定收工。
