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.service2.2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=targeted2)重启虚拟机
reboot2.3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.rpm2）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-scl2.3.2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

baseurl=https://repo.zabbix.com/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=12）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.repo3）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/
