5.1 新建 zabbix Mysql 数据库及专用账号

[usera@mysql ~]  mysql -u root -p
mysql > CREATE DATABASE zabbix character set utf8 collate utf8_bin;
mysql > GRANT all ON zabbix.* TO 'zabbix'@'%' IDENTIFIED BY 'Password';
mysql > flush privileges;
mysql > quit

5.2 确认PHP可正常访问数据库

# /var/www/html/zabbix_connect_test.php

"; $db\_servername = "192.168.99.99"; $db\_username = "zabbix"; $user\_password = "Password"; $db\_name = "zabbix"; $link = mysqli\_connect($db\_servername,$db\_username,$user\_password,$db\_name); if (!$link) { die('Connect Error (' . mysqli\_connect\_errno() . ') ' . mysqli\_connect\_error()); } echo 'Connected successfully' . mysqli\_get\_host\_info($link) . "\\n"; mysqli\_close($link); ?>

# elinks --dump 127.0.0.1/zabbix_connect_test.php
Test db connectionConnected successfully 192.168.99.99 via TCP/IP

5.3 添加 Zabbix 软件仓库

# rpm -ivh http://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

Preparing… ################################# [100%]

5.4 启用Zabbix 前端可选 rpms 的软件仓库
# yum-config-manager --enable rhel-7-server-optional-rpms

5.5 安装 Server/前端
# yum install zabbix-server-mysql

5.6 导入 Zabbix server 的初始数据库 schema 和数据
# scp /usr/share/doc/zabbix-server-mysql*/create.sql.gz usera@192.168.99.99:/tmp/

[root@Mysql tmp]# zcat /tmp/create.sql.gz | mysql -uzabbix -p zabbix
Enter password: ***********
确保导入成功，无报错!

5.7 配置数据库
# vi /etc/zabbix/zabbix_server.conf
DBHost=192.168.99.99
DBName=zabbix
DBUser=zabbix
DBPassword=Password

5.8 启动 Zabbix server 进程
# service zabbix-server start
# systemctl enable zabbix-server

默认LOG目录：/var/log/zabbix/zabbix_server.log

重启一下Httpd 服务后

http://zabbix-server-ip/zabbix

初始登录密码： Admin  /  zabbix

zabbix agent 主被动
----------------------
主动 = agent active
被动 = agent
----------------------
主动与被动的说法均是相对于agent/proxy。
agent/proxy主动发送数据就是主动模式
agent/proxy等待server的请求，再发送数据就是被动模式。
主动模式可减轻Server压力监控项目很多就要把监控模式改为主动
----------------------
主动：ServerActive=ServerIP
agent请求server获取主动的监控项列表，并主动将监控项内需要检测的数据提交给server
server:10051 <-- agent server(item) --> agent
server <-- agent(date) \---------------------- 被动：Server ＝ ServerIP server向agent请求获取监控项的数据，agent返回数据。 server(item) --> agent:10050
server <-- agent(date)
