一、zabbix介绍

百度百科：Zabbix 是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。它是一个企业级的高度集成开源监控软件，可以用来监控设备、服务器、数据库等可用性和性能，保证服务器系统及数据库的安全运营。并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。

zabbix由2部分构成，zabbix server与可选组件zabbix agent。它可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。

一、zabbix部署

1、zabbix环境

IP 主机名 角色
192.168.200.182 zabbix_server 监控服务器
192.168.200.183 web001 业务主机

2、安装zabbix的安装包

安装zabbix_server

1.设置zabbix_server主机名

[root@zabbix_server ~]#hostnamectl set-hostname zabbix_server 或者 hostname  zabbix_server  #设置完成后需要退出终端然后重新打开，新的主机名就生效了

2.关闭防火墙和selinux

[root@zabbix_server ~]# systemctl stop firewalld.service  #停止防火墙服务
[root@zabbix_server ~]# systemctl disable firewalld.service  
[root@zabbix_server ~]# setenforce 0  #临时关闭selinux
setenforce: SELinux is disabled
[root@zabbix_server selinux]# vim   /etc/selinux/config   #编辑配置文件为`SELINUX=disabled` 即可永久关闭selinux

6.安装Zabbix包

  1. 为您的平台安装和配置Zabbix
    在这里插入图片描述
[root@zabbix_server ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
获取https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
  1. 卸载rpm包
[root@zabbix_server ~]# yum remove -y zabbix-release.noarch
  1. 上图是官方的仓库，下载速度很慢，不推荐使用。

国外镜像不可用时，可以使用阿里提供的zabbixYUM源或者国内其他的YUM源。
进入阿里镜像站 地址：https://developer.aliyun.com/mirror/?spm=a2c6h.25603864.0.0.3d501929Ml2fFi

  1. 配置zabbix YUM仓库
[root@zabbix_server ~]# cd /etc/yum.repos.d
[root@zabbix_server yum.repos.d]# ls
CentOS-Base.repo  CentOS-Base.repo.bak  epel.repo  epel-testing.repo  vscode.repo  zabbix.repo
[root@zabbix_server yum.repos.d]# vim zabbix.repo

[zabbix]
name=alibaba zabbix
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/
gpgcheck=0
enabled=1

[zabbix2]
name=alibaba zabbix frontend
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/frontend/
gpgcheck=0

  1. 配置好zabbix yum仓库之后，我清一下列表
[root@zabbix_server ~]# yum repolist

8 为Zabbix server配置数据库

  1. 编辑配置文件 /etc/zabbix/zabbix_server.conf
    将以下这几个配置好货去掉注释
[root@zabbix_server ~]# vim /etc/zabbix/zabbix_server.conf 

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=123456

9 为Zabbix前端配置PHP

1.编辑配置文件 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf 取消注释并为您设置正确的时区。

[root@zabbix_server ~]# vim  /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

php_value[date.timezone] = Asia/Shanghai #只需将这行配置好就是行了，其它的不变
  1. 启动Zabbix server和agent进程
    启动Zabbix server和agent进程，并为它们设置开机自启：
[root@zabbix_server ~]# systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

安装被监控方 web001

  1. 设置 web001 为主机名
[root@web001 ~]#hostnamectl set-hostname web001 或者 hostname  web001  #设置完成后需要退出终端然后重新打开，新的主机名就生效了
  1. 关闭防火墙和selinux
[root@web001 ~]# systemctl stop firewalld.service  #停止防火墙服务
[root@web001 ~]# systemctl disable firewalld.service  
[root@web001 ~]# systemctl status firewalld.service  #查看防火墙状态

   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

[root@web001 ~]# setenforce 0  #临时关闭selinux
setenforce: SELinux is disabled
[root@web001 ~ ]# vim   /etc/selinux/config   #编辑配置文件为`SELINUX=disabled` 即可永久关闭selinux

[root@web001 ~]# getenforce #查看selinux的状态
Disabled
  1. 准备zabbix-repo
#将zabbix_server(192.168.200.182) 的 zabbix.repo 拷贝到 web001(192.168.200.183)
[root@web001 ~]# scp 192.168.200.182:/etc/yum.repos.d/zabbix.repo  /etc/yum.repos.d/

主要问题在于yum源问题或者可以重启网络试试。
5. 查看centos7系统本身所安装的yum依赖包

[root@web001 ~]# rpm -qa|grep yum
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch
yum-utils-1.1.31-54.el7_8.noarch
PackageKit-yum-1.1.10-2.el7.centos.x86_64
yum-3.4.3-168.el7.centos.noarch
  1. 卸载这些软件包
[root@web001 ~]# rpm -e yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch --nodeps
warning: /etc/yum/pluginconf.d/fastestmirror.conf saved as /etc/yum/pluginconf.d/fastestmirror.conf.rpmsave
[root@web001 ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps
[root@web001 ~]# rpm -e yum-3.4.3-168.el7.centos.noarch --nodeps
[root@web001 ~]#
  1. 进入centos镜像网站找到自己对应系统需要的yum包
    查看系统的命令：
[root@web001 ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

查看系统的位数：

[root@web001 ~]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=c8ada1f7095f6b2bb7ddc848e088c2d615c3743e, stripped
[root@web001 ~]#

4.下载yum依赖包

[root@web001 ~]#wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
[root@web001 ~]#wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
[root@web001 ~]#wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm
  1. 安装yum依赖包
[root@web001 ~]# rpm -ivh yum-*
准备中...                          ################################# [100%]
	软件包 yum-metadata-parser-1.1.4-10.el7.x86_64 已经安装
	软件包 yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch (比 yum-plugin-fastestmirror-1.1.31-34.el7.noarch 还要新) 已经安装
....
  1. 更新centos系统的repo文件
    常用网址：

中科大网址：http://mirrors.ustc.edu.cn/help/centos.html
163网址：http://mirrors.163.com/.help/centos.html

6.1 首先备份一下，免得误操作 /etc/yum.repos.d/CentOS-Base.repo

[root@web001 ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

选择自己对应版本的 /etc/yum.repos.d/CentOS-Base.repo文件, 放入/etc/yum.repos.d/ 操作前请做好相应备份

如自己centos版本为7，所以使用版本7的内容。

在这里插入图片描述

vim /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

6.4 配置主服务器地址

[root@web001 ~]# vim /etc/zabbix/zabbix_agentd.conf

Server=192.168.200.182   #者zabbix_server的IP地址
ServerActive=192.200.168.182
Hostname=web001

6.5 启动zabbix-agent：10050

[root@web001 ~]# systemctl start zabbix-agent
[root@web001 ~]# systemctl enable zabbix-agent
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
[root@web001 ~]# ss -anlp |grep :10050
tcp    LISTEN     0      128       *:10050                 *:*                   users:(("zabbix_agentd",pid=112433,fd=4),("zabbix_agentd",pid=112432,fd=4),("zabbix_agentd",pid=112431,fd=4),("zabbix_agentd",pid=112430,fd=4),("zabbix_agentd",pid=112429,fd=4),("zabbix_agentd",pid=112428,fd=4))
tcp    LISTEN     0      128    [::]:10050              [::]:*                   users:(("zabbix_agentd",pid=112433,fd=5),("zabbix_agentd",pid=112432,fd=5),("zabbix_agentd",pid=112431,fd=5),("zabbix_agentd",pid=112430,fd=5),("zabbix_agentd",pid=112429,fd=5),("zabbix_agentd",pid=112428,fd=5))
[root@web001 ~]#

测试
在zabbix_server(192.168.200.182) 上使用zabbix_get(命令行监控) 进行收集客户端数据收集

因为在5.0zabbix并没有默认安装zabbix-get，所以需要在zabbix_server上安装

[root@web001 ~]# yum install -y zabbix-get
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
软件包 zabbix-get-5.0.28-1.el7.x86_64 已安装并且是最新版本
无须任何处理


[root@zabbix_server ~]# zabbix_get -s 192.168.200.183 -k system.uname
Linux web001 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64

[root@zabbix_server ~]# zabbix_get -s 192.168.200.183 -k system.cpu.load[all,avg15]
0.050000

到这里则完成了zabbix_server 对 web001 的监控
