Zabbix系列（三）：服务端部署

废权 • 2018-09-08 • DevOps

采用zabbix与Grafana项结合的部署方式，由zabbix agent提供数据采集，Grafana进行前端数据展示，适用与日常运维和信息采集。

一、基础环境

操作系统：CentOS7.1 1503 关闭防火墙和Selinux，内部自带CentOS7.1 yum源，系统外加一块硬盘作为数据盘（300G）。

序号 软件名称 软件版本
1 Zabbix server/agent 3.2.4
2 Mariadb 5.5
3 Grafana 3.2.1
4 httpd 2.46

在root目录下创建zabbix_install目录，目录下包含zabbix_package.tar.gz文件，该文件包含Zabbix安装的所需要的所有rpm包，安装脚本也在该目录下。

二、Zabbix安装

这里采用脚本自动安装

[root@host zabbix_install]# pwd
/root/zabbix_install
[root@host zabbix_install]# ls
zabbix_install.sh  zabbix_package.tar.gz
[root@host zabbix_install]# chmod +x zabbix_install.sh 
[root@host zabbix_install]# sh zabbix_install.sh

脚本内容：

#!/bin/bash

Timestamp=`date "+%Y-%m-%d %H:%M:%S"`
echo -e "$Timestamp 安装开始 " >> /root/zabbix_install/zabbix_install.log
echo -e "\033[1;32m$Timestamp 安装开始 \033[0m"
lsblk|grep -E sd'[b-z]' >/dev/null 2>&1
status=`echo $?`
if [ $status -eq 0 ]
then
    echo -e "$Timestamp 磁盘检测完成 " >> /root/zabbix_install/zabbix_install.log
    echo -e "\033[1;32m$Timestamp 磁盘检测完成 \033[0m"
else
    echo -e  "$Timestamp 数据盘不存在，请检查磁盘 " >> /root/zabbix_install/zabbix_install.log
    echo -e  "\033[1;31m$Timestamp 数据盘不存在，请检查磁盘 \033[0m" && exit

三、检查服务

[root@host zabbix_install]# netstat -ntlp |grep -E "3306|80|3000"
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      29621/mysqld        
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      25051/nginx: master 
tcp6       0      0 :::80                   :::*                    LISTEN      1236/httpd          
tcp6       0      0 :::3000                 :::*                    LISTEN      29810/grafana-serve

若安装失败请查看zabbix_install.log日志并修改shell脚本后再执行脚本，或手动安装。。。

四、Zabbix服务初始化

（1）基础设置

打开浏览器，访问http://x.x.x.x/zabbix (x.x.x.x为服务器IP)，点击“Next step”
7-4

Check项均为OK时，点击“Next step”
7-5

输入密码“zabbix”，点击“Next step”。
7-6

设置完成后跳转至登陆页面，登陆账户为：Admin,密码为：zabbix
7-7

点击右上角图标，进行中文设置：
7-8
7-9

登陆前端展示Grafana，浏览器访问http://x.x.x.x:3000/login
7-10

激活Zabbix-grafana插件
7-11
7-12

添加zabbix作为数据源，
数据源名称：zabbix-server
勾选Default
Type：选择zabbix
url输入：http://127.0.0.1/zabbix/api_jsonrpc.php
Username：Admin
Password：zabbix
7-13
7-14
7-15

（2）导入模板

点击“configuration”下的“template”选项，将默认的模板全部删除。
7-15-1
7-15-2

点击import导入模板，将安装包内mytest_template.xml进行导入。
模板下载地址~请点击这里~
7-16

（3）控制节点自动注册

点击“Configuration”下的“Actions”选项，点击右上角进行动作创建。
7-17

配置Linux节点自动注册
名称填写：Linux-agent
选择新触发条件为“Auto registration”
填写值：Linux-agent
7-18-1

添加自动注册动作。
选择操作类型：“Add host”。
7-19

点击“Add”。
7-20

添加主机添加群组动作。
选择操作类型：“Add to host group”。
点击选择“Linux-agent”组。
点击“Add”。
7-21

添加与模板关联
选择操作类型：“Link to template”。
点击选择,”Linux-agent”模板。
7-23

点击“Add”
7-24

已同样的方法配置Windows节点自动注册，完成后如下图所示
7-25-1
