Zabbix (二) --------- Zabbix 部署

---

一、集群规划

二、准备工作

1. 关闭集群

如果集群开启，先关闭集群。因为安装 Zabbix 前，需要重启虚拟机。

2. 关闭 3 台节点防火墙

分别在 hadoop 102、103 和 104 上执行

sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service
1
2

3. 关闭 3 台节点上的 SELinux

A、修改配置文件 /etc/selinux/config

[fancy@hadoop102 ~]$ sudo vim /etc/selinux/config
1

修改如下内容

# 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 these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

B、重启服务器

[fancy@hadoop102 ~]$ sudo reboot
1

三、配置 3 台节点的 Zabbix yum 源

1. 安装 yum 仓库

A、安装 zabbix 的软件仓库配置包

这个包包含了 yum (软件包管理器) 的配置文件。

[fancy@hadoop102 ~]$ sudo rpm -Uvh
https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
[fancy@hadoop103 ~]$ sudo rpm -Uvh
https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
[fancy@hadoop104 ~]$ sudo rpm -Uvh
https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

B、安装 Software Collections 仓库

[fancy@hadoop102 ~]$ sudo yum install -y centos-release-scl
[fancy@hadoop103 ~]$ sudo yum install -y centos-release-scl
[fancy@hadoop104 ~]$ sudo yum install -y centos-release-scl

2. 修改 zabbix 仓库配置文件

hadoop102、hadoop103、hadoop104 三台节点，依次执行如下步骤。

A、查看原始 zabbix.repo 文件

[fancy@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo
查看内容如下
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend

B、执行以下命令完成全局替换，修改为阿里云镜像

[fancy@hadoop102 ~]$ sudo sed -i
's/http:\/\/repo.zabbix.com/https:\/\/mirrors.aliyun.com\/zabbix/g' /etc/yum.repos.d/zabbix.repo

C、查看修改之后的 zabbix.repo 文件

[fancy@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo
查看内容如下

修改如下内容：
[zabbix]
user = apache

/var/opt/rh/rh-php72/lib/php/session/
php_value[max_execution_time] = 300
php_value[memory_limit] = 128M
php_value[post_max_size] = 16M
php_value[upload_max_filesize] = 2M

六、启动停止 Zabbix

1. 启动 Zabbix

[fancy@hadoop102 ~]$ sudo systemctl start zabbix-server zabbix-agent httpd rh-php72-php-fpm
[fancy@hadoop102 ~]$ sudo systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm
[fancy@hadoop103 ~]$ sudo systemctl start zabbix-agent
[fancy@hadoop103 ~]$ sudo systemctl enable zabbix-agent
[fancy@hadoop104 ~]$ sudo systemctl start zabbix-agent
[fancy@hadoop104 ~]$ sudo systemctl enable zabbix-agent

2. 停止 Zabbix

[fancy@hadoop102 ~]$ sudo systemctl stop zabbix-server zabbix-agent
httpd rh-php72-php-fpm
[fancy@hadoop102 ~]$ sudo systemctl disable zabbix-server
zabbix-agent httpd rh-php72-php-fpm
[fancy@hadoop103 ~]$ sudo systemctl stop zabbix-agent
[fancy@hadoop103 ~]$ sudo systemctl disable zabbix-agent

3. 连接 Zabbix_Web 数据库

A、浏览器访问 http://hadoop102/zabbix/

B、检查配置

C、配置数据库

D、配置 zabbix-server

4. 登录 Zabbix

A、用户名：Admin 密码：zabbix

B、点击 User Settings，语言设成中文

注意：这里默认会对 Zabbix Server 进行监控，但是我们可以看到目前该主机是红色，不可用的状态，原因是主机的地址不能使用 127.0.0.1 需要后续我们单独配置。
