Zabbix部署

1.集群规划

进程	虚拟机节点1	虚拟机节点2	虚拟机节点3
zabbix-agent	√	√	√
zabbix-server	√
PostgreSQL	√
zabbix-web	√

2.准备工作

默认在虚拟机节点2安装kafka、在虚拟机节点3安装redis

2.1关闭3台节点防火墙

sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service

2.2关闭3台节点上的SELinux

1）修改配置文件/etc/selinux/config

vim /etc/selinux/config# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2)重启虚拟机

reboot

2.3配置3台节点的Zabbix yum源

2.3.1安装yum仓库

**1）**** 安装 zabbix 的软件仓库配置包**

分别在三个节点下运行一下这个命令

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-latest.el7.noarch.rpm

2）安装Software Collections仓库

分别在三个节点下运行一下这个命令

yum install -y centos-release-scl

2.3.2修改zabbix仓库配置文件

**1）查看原始zabbix.repo文件**

cat /etc/yum.repos.d/zabbix.repo##查看内容如下所示
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://repo.zabbix.com/zabbix/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=https://repo.zabbix.com/zabbix/zabbix/5.0/rhel/7/$basearch/frontend

gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-debuginfo]

baseurl=https://repo.zabbix.com/zabbix/zabbix/5.0/rhel/7/$basearch/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://repo.zabbix.com/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

2）执行以下命令完成全局替换，修改为阿里云的镜像

sed -i 's/http:\/\/repo.zabbix.com/https:\/\/mirrors.aliyun.com\/zabbix/g' /etc/yum.repos.d/zabbix.repo

3）查看修改之后的zabbix.repo文件

cat /etc/yum.repos.d/zabbix.repo##内容如下
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-frontend]

gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-debuginfo]

enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

4）打开/etc/yum.repos.d/zabbix.repo文件，启用zabbix-web仓库

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/frontend
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/debuginfo/

enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1
