zabbix server、agent安装及使用

先准备yum源，当然你有打好的rpm包那更好

 [root@linux-node1 ~]# cat /etc/yum.repos.d/zabbix.repo

 [zabbix]

 name=Zabbix Official Repository - $basearch

 baseurl=https://mirror.tuna.tsinghua.edu.cn/zabbix/zabbix/3.0/rhel/7/x86_64/

 enabled=

 gpgcheck=

 [root@linux-node1 ~]# yum install zabbix-server mariadb mariadb-server httpd zabbix-web php-mysql php –y    # node1安装server、数据库

 [root@linux-node2 ~]# yum install zabbix-agent zabbix-proxy mariadb mariadb-server –y        # node2安装proxy、数据库、agent

 [root@linux-node3 ~]# yum install zabbix-agent –y        # node3只安装agent，当然你也可以没有node3，这个不重要

把node1跟node2上的数据库起来并且做好你的安全初始化再继续

 [root@linux-node1 ~]# mysql -uroot -p123 -e "create database zabbix character set utf8 collate utf8_bin;"

 [root@linux-node1 ~]# mysql -uroot -p123 -e "grant all on zabbix.* to zabbix@'localhost' identified by 'zabbix';"

 [root@linux-node1 ~]# cd /usr/share/doc/zabbix-server-mysql-3.0./

至此server端安装完毕，我们访问下http://ip/zabbix

帐号密码：Admin/zabbix

基础常用功能

1.更改页面展示语言（中文一些翻译术语不是很好理解）

2.用户登录后直接跳转到某url，针对不同用户关注点不同

3.页面排版，直接拖拽即可

4.启用、禁用主机，直接点击即可

安装一台agent并让他被监控，我们去node2上去操作了，刚才已经安装了需要的包，我们直接修改配置文件启动即可
