Zabbix运维平台

Zabbix部署

1.集群规划

进程	hadoop102节点	hadoop103节点	hadoop104节点
zabbix-agent	√	√	√
zabbix-server	√
MySQL	√
zabbix-web	√

2.准备工作

2.1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。

2.2关闭3台节点防火墙

分别在hadoop102、103、104上执行：

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

2.3关闭3台节点上的SELinux

(1) 修改配置文件/etc/selinux/config

sudo vim /etc/selinux/config

修改为一下内容：

# 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 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) 重启服务器

sudo reboot

3.配置3台节点的Zabbix yum源

3.1安装yum仓库

(1) 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

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

(2) 安装Software Collectiopns仓库

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

3.2修改zabbix仓库配置文件

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

(1) 查看原始zabbix.repo文件

[wwj@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

(2) 执行以下命令完成全局替换，修改为阿里云镜像

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

(3) 查看修改后的zabbix.repo文件

[wwj@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 - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$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

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

将文件中zabbix-frontend的enabled=0改为enabled=1

[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

4.安装Zabbix

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

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

5.配置Zabbix

5.1创建Zabbix数据库

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

5.2导入Zabbix建表语句

[wwj@hadoop102 ~]$ zcat /usr/share/doc/zabbix-server-mysql-5.0.42/create.sql.gz | mysql -uroot -p123456 zabbix

5.3配置Zabbix_Server（hadoop102）

修改zabbix-server配置文件

[wwj@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_server.conf

DBHost=hadoop102
DBName=zabbix
DBUser=root
DBPassword=123456

5.4配置Zabbix_Agent（三台节点）

修改zabbix-agent配置文件

[wwj@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf
[wwj@hadoop103 ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf
[wwj@hadoop104 ~]$ sudo vim /etc/zabbix/zabbix_agentd.conf

修改以下内容：

Server=hadoop102
#ServerActive=127.0.0.1
#Hostname=Zabbix server

5.5配置Zabbix_Web时区

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

[wwj@hadoop102 ~]$ sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

修改如下内容：（最后一行：php_value[date.timezone] = Asia/Shanghai）

[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
pm.max_requests = 200

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

修改MySQL8.0的密码加密规则

alter user 'root'@'localhost' identified with mysql_native_password by '123456';
select user,host,plugin,authentication_string from user;

6.启动停止Zabbix

6.1启动Zabbiz

wwj@hadoop102 ~$ sudo systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
wwj@hadoop102 ~$ sudo systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

[wwj@hadoop103 ~]$ sudo systemctl start zabbix-agent
[wwj@hadoop103 ~]$ sudo systemctl enable zabbix-agent

[wwj@hadoop104 ~]$ sudo systemctl start zabbix-agent
[wwj@hadoop104 ~]$ sudo systemctl enable zabbix-agent

6.2停止Zabbiz

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

[wwj@hadoop103 ~]$ sudo systemctl stop zabbix-agent
[wwj@hadoop103 ~]$ sudo systemctl disable zabbix-agent

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

6.3访问Web网页

打开：http://hadoop102/zabbix/ 即可访问zabbix-server,点击下一步，对数据库进行配置：

配置Zabbix server details

完成之后就可以登录Zabbix页面了

6.4登录Zabbix

(1) 登录账号

用户名：Admin 密码：zabbix

(2) 设置界面语言
