Zabbix Server和MPM(monitor for mysql)的快速部署

1. 前言

        zabbix作爲開源免費的監控軟件，其易於管理配置和可視化的視圖、歷史數據的定期維護、模板化的監控項目越來越受到廣大IT運維人員的喜愛。這裏主要是總結了下Zabbix Server和MPM使用yum進行快速部署。其更加詳細的東西，大家還是看官方文檔吧。我們首先把環境搭起來！

2. 環境

1）Zabbix Server

Os：Redhat6.5 i686(vmware)

        ipaddr：192.168.8.3

        hostname：linux-zabbix

        MySQL ：5.6.23

        MEM：1G

2）監控端

        Os：CentOS 6.4 x64(vmware)

        ipaddr：192.168.8.5

        hostname：oneproxy-vm

        MEM：1G

3. Zabbix Server部署

3.1 yum環境配置

這裏的yum源使用的是163的CentOS6.6和zabbix官網的源。

由於我的server安裝的是rehat，所以首先要把redhat的yum卸載掉，安裝centOS的yun軟件。

3.1.1 下載centos yum軟件

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

3.1.2 卸載redhat的yum包

rpm -qa|grep -i yum|xargs rpm -e --nodeps

3.1.3 安裝centOS的yum包

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

3.1.4 配置163的CentOS6.6的yum

[root@linux-zabbix yum.repos.d]# cd /etc/yum.repos.d
[root@linux-zabbix yum.repos.d]# cat CentOS6-Base-163.repo 
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#

3.1.5 配置zabbix的yum源

wget http://repo.zabbix.com/zabbix/2.4/rhel/6/i386/zabbix-release-2.4-1.el6.noarch.rpm
rpm -ivh zabbix-release-2.4-1.el6.noarch.rpm

[root@linux-zabbix yum.repos.d]# cat zabbix.repo

3.2 Zabbix Server安裝

3.2.1 安裝mysql數據庫

yum remove mysql-libs-5.1.71-1.el6.i686
rpm -ivh MySQL-server-advanced-5.6.23-1.el6.i686.rpm
rpm -ivh MySQL-client-advanced-5.6.23-1.el6.i686.rpm

3.2.2 配置mysql

創建目錄

mkdir -p /var/lib/mysql/tmp
mkdir -p /var/lib/mysql/logs
chown -R mysql:mysql /var/lib/mysql

初始化mysql

mysql_install_db --defaults-file=/etc/my.cnf --datadir=/var/lib/mysql/

啓動數據庫後，創建zabbix數據庫，設置root密碼

service mysql start
mysql> create database zabbix default charset utf8;

mysql> grant all on *.* to 'root'@'localhost' identified by '123456';

mysql> grant all on *.* to 'root'@'%' identified by '123456';

mysql> flush privileges;

3.2.3 安裝zabbix

yum install zabbix-server-mysql zabbix-web-mysql
yum install zabbix-get

yum會自動的將apache和php安裝配置好。

3.2.4 初始化zabbix數據庫

cd /usr/share/doc/zabbix-server-mysql-2.4.5/create

[root@linux-zabbix create]# mysql -p123456 -uroot zabbix < schema.sql
[root@linux-zabbix create]# mysql -p123456 -uroot zabbix < images.sql 
[root@linux-zabbix create]# mysql -p123456 -uroot zabbix < data.sql 

3.2.5 修改zabbix server配置文件

cat /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=root
DBPassword=123456

3.2.6 修改php配置文件

php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
date.timezone = PRC

3.2.7 啓動服務

service zabbix-server start
servivce httpd start

3.2.8 配置頁面

打開 http://192.168.8.3/zabbix 後，配置相關選項

安裝要求檢查

數據庫配置

zabbix-server

安裝預覽

完成後，可以使用默認管理員用戶admin/zabbix進行登錄

4. 配置Zabbix Agent和MPM

4.1 zabbix agent配置

yum的配置上一部分已經說了，直接安裝

yum install zabbix-agent
yum install zabbix-sender

配置/etc/zabbix/zabbix_agentd.conf

Server=192.168.8.3
ServerActive=192.168.8.3
Hostname=oneproxy-vm

4.2 MPM安裝配置

4.2.1 安裝依賴包

yum install perl-File-Which perl-libwww-perl perl-Digest-SHA perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay

4.2.2 軟件介紹

        到官網http://www.fromdual.com/ 下載MPM的相關版本，這裏我使用的是mysql_performance_monitor-0.9.3.tar.gz。(PS：最新的0.10版本沒有相關文檔，簡直坑啊！)

解壓縮軟件包後，會發現有兩個文件mysql_performance_monitor_agent-0.9.3.tar.gz和mysql_performance_monitor_templates-0.9.3.tar.gz。其中mysql_performance_monitor_agent-0.9.3.tar.gz是放在監控機器上的配置信息，mysql_performance_monitor_templates-0.9.3.tar.gz則是要讓我們導入到zabbix server的模板數據。

4.2.3 模板導入

登錄到我們的zabbix server服務器上，通過Configuration-->Templates-->Import進行模板導入

將mysql_performance_monitor_templates-0.9.3.tar.gz解壓縮後Template_FromDual.MySQL.mpm.xml是必須導入的，我們優先導入。其他的大家根據需求進行導入。我這裏是將所有模板導入了。

4.2.4 創建監控host

通過Configuration-->Host groups創建一個用戶組。我這裏創建名稱爲mpm的用戶組。

通過Configuration-->Hosts創建一個用戶，將其加入到mpm用戶組中，關聯的Template使用我們導入的。

關聯Template

ok，我們的server端就配置完畢了。

4.2.5 MPM agent配置

解壓縮我們的agent軟件包mysql_performance_monitor_agent-0.9.3.tar.gz，將其放到/opt目錄下

mv mysql_performance_monitor_agent-0.9.3 /opt/mysql_performance_monitor_agent

cd /opt/mysql_performance_monitor_agent/etc
cp FromDualMySQLagent.conf.template /etc/zabbix/FromDualMySQLagent.conf
mkdir -p /var/log/zabbix /var/log/zabbix/cache
chown -R zabbix: /var/log/zabbix /var/log/zabbix/cache

編輯/etc/zabbix/zabbix-agent.conf，添加

UserParameter=FromDual.MySQL.check,/opt/mysql_performance_monitor_agent/FromDualMySQLagent.pl /etc/zabbix/FromDualMySQLagent.conf

修改MPM配置文件

[root@oneproxy-vm zabbix]# cat /etc/zabbix/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
LogFile       = /var/log/zabbix/FromDualMySQLagent.log
# Directory where the Cache files should be written to:
CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache

# If you agent is not located in the same time zone as your server
# For US something like -6.0 to our MaaS Server
# For Asia something like +7.0 to our MaaS Server
# TimeShift = +0.0

# Information for MySQL connections:
Username     = root
Password     = 123456
MysqlHost    = 127.0.0.1
MysqlPort    = 3306

# Zabbix Server IP address
ZabbixServer = 192.168.8.3

</pre><pre name="code" class="html"># 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
[oneproxy-vm]          # This MUST match Hostname in Zabbix!

Type         = mysqld
Username     = root
Password     = 123456
MysqlHost    = 127.0.0.1
MysqlPort    = 3306
Modules      = process mysql myisam innodb
PidFile      = /data/mysql_3306/mysql.pid

其中default字段是默認的，oneproxy-vm字段必須與zabbix-server中配置的hosts名稱相等。其他的根據自己的本地mysql環境進行配置。

給予zabbix對pid文件的讀權限和MPM日誌的權限

chmod o+r /data/mysql_3306/mysql.pid

touch /var/log/zabbix/FromDualMySQLagent.log

chown -R zabbix:zabbix /var/log/zabbix

啓動zabbix-agent即可

service zabbix-agent start
