1.Zabbix的安装及简单的配置

服务端1

A)安装zabbix

[[email protected] zabbix]# yum install zabbix-2.4.5-1.el6.x86_64.rpmzabbix-agent-2.4.5-1.el6.x86_64.rpm zabbix-get-2.4.5-1.el6.x86_64.rpmzabbix-server-2.4.5-1.el6.x86_64.rpm zabbix-server-mysql-2.4.5-1.el6.x86_64.rpmzabbix-web-2.4.5-1.el6.noarch.rpm zabbix-web-mysql-2.4.5-1.el6.noarch.rpmfping-2.4b2-16.el6.x86_64.rpm iksemel-1.4-2.el6.x86_64.rpm iksemel-utils-1.4-2.el6.x86_64.rpm php-* -y #安装zabbix

B)配置mysql数据库

[[email protected] ~]# mysql -predhat

mysql> create database zabbix1 character set utf8 collateutf8_bin;

Query OK, 1 row affected (0.00 sec) #创建zabbix数据库

mysql> grant all privileges on zabbix1.* to [email protected] by ‘redhat‘;

Query OK, 0 rows affected (0.00 sec) #给zabbix数据库授权

mysql> Ctrl-C -- exit!

[[email protected] ~]# mysql -uzabbix -predhat #用新创建的用户测试登陆

mysql> show databases;

+--------------------+

| Database |

+--------------------+

| information_schema |

| zabbix1 |

+--------------------+

2 rows in set (0.00 sec)

mysql> Ctrl-C -- exit!

[[email protected] mysql]# cd/usr/share/doc/zabbix-server-mysql-2.4.5/create/

[[email protected] create]# ls

data.sql images.sql schema.sql

#将文件导入数据库

[[email protected] create]# mysql -uzabbix -predhat zabbix1<schema.sql

[[email protected] create]# mysql -uzabbix -predhat zabbix1<images.sql

[[email protected] create]# mysql -uzabbix -predhat zabbix1 <data.sql

[[email protected] zabbix]# cd /etc/httpd/conf.d/

C)配置zabbix server和zabbix agent

[[email protected] conf.d]# vim zabbix.conf #修改时区

php_value date.timezoneAsia/Shanghai

[[email protected] create]# cd /etc/zabbix/

[[email protected] zabbix]# vim zabbix_server.conf #将zabbix数据库的信息添加进去

DBName=zabbix1
DBUser=zabbix
DBPassword=redhat

[[email protected] zabbix]# vim zabbix_agentd.conf #修改主机名

Hostname=server1.example.com

D)启动zabbix-serverzabbix-agent httpd

[[email protected] conf.d]# /etc/init.d/zabbix-server start

Starting Zabbix server: [ OK ]

[[email protected] zabbix]# /etc/init.d/zabbix-agent start

Starting Zabbix agent: [ OK ]

[[email protected] conf.d]# /etc/init.d/httpd start

Starting httpd: [ OK ]

E)访问172.25.25.1/zabbix

如图：点击next

如图: 数据库名字，用户，密码（刚才在数据库里新建的），点击Test Connection检测是否连接数据库（ok表示已连接），点击next

Name可以随意填写，点击next

之后点击finsh，登陆：用户名：Admin 密码：zabbix

登陆进去，如图：

2.在server中添加agent主机

服务端2

A)安装zabbixagent、配置zabbix agent及开启

[[email protected] zabbix]# yum install -yzabbix-2.4.5-1.el6.x86_64.rpm zabbix-agent-2.4.5-1.el6.x86_64.rpm -y

[[email protected] ~]# cd /etc/zabbix/

[[email protected] zabbix]# vim zabbix_agentd.conf

Server=172.25.25.1                             #zabbixserver端ip
ServerActive=172.25.25.1                          
Hostname=server2.example.com                   #本机主机名

[[email protected] zabbix]# /etc/init.d/zabbix-agent start

Starting Zabbix agent: [ OK ]

B)将zabbix agent主机添加到zabbix zerver

点击Configure->Actions 如图，在Event source中选择Auto registration（自动注册），点击Create action

如图，作如下设置：Action中name 自定义，Conditions选项卡保持默认

Operation选项卡点击Add添加

添加结果如下：Add host:自动注册主机添加到 hosts 列表

Add to host groups:自动注册主机加入linux servers 组(组名可以自定义)

Link totemplates:自动注册主机应用模板 Template OS linux

点击 Configuration -> Hosts 可以看到新加的主机:

3.在server中添加agent的服务监控项

利用 zabbix 自带的监控模版,以 http 和mysqld服务为例

服务端2

A)配置开启http和mysql服务

[[email protected] zabbix]# /etc/init.d/httpd start #开启httpd

Starting httpd: [ OK ]

[[email protected] zabbix]# /etc/init.d/mysqld start #开启mysqld

Starting mysqld: [ OK ]

[[email protected] zabbix]# mysql -predhat

mysql> grant select on *.* to [email protected] identified by‘redhat‘;

Query OK, 0 rows affected (0.00 sec) #创建本地用户，并给其权限

mysql> Ctrl-C -- exit!

在/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf 文件中指定了 zabbix agent 如何获取 mysql服务的各种信息,并在/var/lib/zabbix 目录中新建“.my.cnf”文件,用以指定zabbix agent 如何登陆数据库，可以在 zabbix_server.conf 文件中找到密码。

[[email protected] zabbix]# cd zabbix_agentd.d/

[[email protected] zabbix_agentd.d]# mkdir /var/lib/zabbix #创建目录

[[email protected] zabbix_agentd.d]# cd /var/lib/zabbix/

[[email protected] zabbix]# vim .my.cnf #编写文件，如下

[mysql]
host=localhost
user=wen                                                   #刚创建的用户
password=redhat                                            #用户wen的密码
socket=/var/lib/mysql/mysql.sock
[mysqldadmin]
host=localhost
user=wen
password=redhat
socket=/var/lib/mysql/mysql.sock

[[email protected] zabbix]# /etc/init.d/zabbix-agent restart #重启服务

Shutting down Zabbix agent: [ OK ]

Starting Zabbix agent: [ OK ]

B)添加模版 httpd服务和mysql服务

点击Configuration -> Hosts -> server2.example.com-> Templates 选择需要的模版添加，如图:

点击server2.example.com的Items,就出现了http服务，如图;
