## 一、集群规划 ##

![在这里插入图片描述][fedc8984571e4381b47b8e1b143657a3.png]

## 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

### 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

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

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

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

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

## 四、安装 Zabbix ##

在 hadoop102、hadoop103、hadoop104 三台节点分别执行以下安装命令

[fancy@hadoop102 ~]$ sudo yum install -y zabbix-server-mysql zabbix-agent zabbix-web-mysql-scl zabbix-apache-conf-scl
    [fancy@hadoop103 ~]$ sudo yum install -y zabbix-agent
    [fancy@hadoop104 ~]$ sudo yum install -y zabbix-agent

## 五、配置 Zabbix ##

### 1. 创建 zabbix 数据库 ###

[fancy@hadoop102 ~]$ mysql -uroot -p123456 -e "create database zabbix character set utf8 collate utf8_bin"

### 2. 导入 Zabbix 建表语句 ###

[fancy@hadoop102 ~]$ zcat
    /usr/share/doc/zabbix-server-mysql-5.0.18/create.sql.gz | mysql -uroot -p123456 zabbix

### 3. 配置 Zabbix\_Server (hadoop102) ###

修改 zabbix-server 配置文件

[fancy@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_server.conf
    DBHost=hadoop102
    DBName=zabbix
    DBUser=root
    DBPassword=123456

### 4. 配置 Zabbix\_Agent (三台节点) ###

修改 zabbix-agent 配置文件

[fancy@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf
    修改如下内容：
    Server=hadoop102
    #ServerActive=127.0.0.1
    #Hostname=Zabbix server

### 5. 配置 Zabbix\_Web 时区 ###

修改/etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf 文件

[fancy@hadoop102 ~]$ sudo vim
    /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
    修改如下内容：
    [zabbix]
    user = apache
    group = apache
    listen = /var/opt/rh/rh-php72/run/php-fpm/zabbix.sock
    listen.acl_users = apache
    listen.allowed_clients = 127.0.0.1
    pm = dynamic
    pm.max_children = 50
    pm.start_servers = 5
    pm.min_spare_servers = 5
    pm.max_spare_servers = 35
    php_value[session.save_handler] = files
    php_value[session.save_path] =
    /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
    php_value[max_input_time] = 300
    php_value[max_input_vars] = 10000
    php_value[date.timezone] = Asia/Shanghai

## 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
    [fancy@hadoop104 ~]$ sudo systemctl stop zabbix-agent
    [fancy@hadoop104 ~]$ sudo systemctl disable zabbix-agent

### 3. 连接 Zabbix\_Web 数据库 ###

> 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。
