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
三、Zabbix3.4安装及配置
1、Zabbix3.4新功能概述 More newly developed and improved features of Zabbix 3.4 are now availabe for you!

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。
