一、系統環境
cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
關閉防火牆及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、數據庫安裝及配置
1、MariaDB概述
MariaDB數據庫管理系統是MySQL的一個分支，主要由開源社區在維護，採用GPL授權許可。
開發這個分支的原因是：甲骨文公司收購了MySQL後，有將MySQL閉源的潛在風險，因此社區採用分支的方式來避開這個風險。
MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能輕鬆成爲MySQL的代替品。
2、安裝mariadb
yum install mariadb-server mariadb -y
mariadb數據庫的相關命令是：
systemctl start mariadb #啓動MariaDB
systemctl stop mariadb #停止MariaDB
systemctl restart mariadb #重啓MariaDB
systemctl enable mariadb #設置開機啓動

2、Zabbix3.4安裝
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、創建數據庫
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
4、導入數據
zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -uzabbix -pzabbix zabbix
5、配置數據庫用戶及密碼
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、啓動zabbix server並設置開機啓動
systemctl enable zabbix-server
systemctl start zabbix-server
7、編輯Zabbix前端PHP配置,更改時區
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、啓動httpd並設置開機啓動
systemctl start httpd
systemctl enable httpd
四、安裝Zabbix Web
1、瀏覽器訪問,並進行安裝
http://10.12.7.116/zabbix/
2、點擊next會出現檢查狀態
3、檢查系統環境設置，必須全部都爲ok，才能繼續
4、輸入連接到數據庫詳細信息。Zabbix數據庫必須已經創建好
5、連接Zabbix服務細節，如果沒有改變可選擇默認
7、完成安裝，會將在/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、登錄最新版Zabbix3.4 默認用戶Admin 默認密碼zabbix
五、zabbxi-agent安裝及配置
