一、系统环境

cat /etc/redhat-release
CentOS Linux release 7.2 (Core)

关闭防火墙及selinux

systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0

二、数据库安装及配置

1、MariaDB概述
MariaDB数据库管理系统是MySQL的一个分支,主要由开源社区在维护,采用GPL授权许可。
开发这个分支的原因是:甲骨文公司收购了MySQL后,有将MySQL闭源的潜在风险,因此社区采用分支的方式来避开这个风险。
MariaDB的目的是完全兼容MySQL,包括API和命令行,使之能轻松成为MySQL的代替品。

2、安装mariadb
yum install mariadb-server mariadb -y
mariadb数据库的相关命令是:

systemctl start mariadb  #启动MariaDB
systemctl stop mariadb  #停止MariaDB
systemctl restart mariadb  #重启MariaDB
systemctl enable mariadb  #设置开机启动

2、Zabbix3.4安装

rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
yum install zabbix-server-mysql zabbix-web-mysql -y

3、创建数据库
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

4、导入数据

zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -uzabbix -pzabbix zabbix

5、配置数据库用户及密码
grep -n '^'[a-Z] /etc/zabbix/zabbix_server.conf
38:LogFile=/var/log/zabbix/zabbix_server.log
49:LogFileSize=0
72:PidFile=/var/run/zabbix/zabbix_server.pid
99:DBName=zabbix
115:DBUser=zabbix
123:DBPassword=zabbix
314:SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
432:Timeout=4
474:AlertScriptsPath=/usr/lib/zabbix/alertscripts
484:ExternalScripts=/usr/lib/zabbix/externalscripts
520:LogSlowQueries=3000

6、启动zabbix server并设置开机启动

systemctl enable zabbix-server
systemctl start zabbix-server

7、编辑Zabbix前端PHP配置,更改时区
vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai

8、SELinux配置

setsebool -P httpd_can_connect_zabbix on
setsebool -P httpd_can_network_connect_db on

9、启动httpd并设置开机启动

systemctl start httpd
systemctl enable httpd

四、安装Zabbix Web

1、浏览器访问,并进行安装
http:// 192.168.1.140/zabbix/

2、点击next会出现检查状态

3、检查系统环境设置,必须全部都为ok,才能继续

4、输入连接到数据库详细信息。Zabbix数据库必须已经创建好

5、连接Zabbix服务细节,如果没有改变可选择默认

7、完成安装,会将在/etc/zabbix/web/zabbix.conf.php生成配置文件
Congratulations! You have successfully installed Zabbix frontend.
Configuration file "/etc/zabbix/web/zabbix.conf.php" created.

8、登录最新版Zabbix3.4 默认用户Admin 默认密码zabbix

五、zabbxi-agent安装及配置

1、安装zabbxi-agent
yum install zabbix-agent -y

2、配置zabbxi-agent
grep -n '^'[a-Z] /etc/zabbix/zabbix_agentd.conf
13:PidFile=/var/run/zabbix/zabbix_agentd.pid
32:LogFile=/var/log/zabbix/zabbix_agentd.log
43:LogFileSize=0
97:Server=172.16.8.254
138:ServerActive=172.16.8.254
149:Hostname=Zabbix server
267:Include=/etc/zabbix/zabbix_agentd.d/*.conf

3、启动zabbxi-agent并设置开机启动

systemctl enable zabbix-agent.service
systemctl restart zabbix-agent.service

zabbix添加监控主机。

1、 监控主机安装agent程序并启动。
2、 关掉selinux,firewalld。
3、 配置etc/zabbix/zabbxi-agentd.conf,其中server=server端ip(192.168.1.140),serveractive=agent端ip,hostname与server端配置一致即可。
