Zabbix 6.0
一.Zabbix介绍
1.zabbix 的含义
- zabbix 是一个基于 Web 界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案
- zabbix 能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题
- zabbix 由 2 部分构成，zabbix server 与可选组件 zabbix agent。通过 C/S 模式采集数据，通过 B/S 模式在 Web 端展示和配置
- zabbix server 可以通过 zabbix agent，SNMP协议，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在 Linux 等平台上
- zabbix agent 需要安装在被监视的目标服务器上，它主要完成对硬件信息或与操作系统有关的内存，CPU 等信息的收集
2.zabbix 的监控原理
- zabbix agent 安装在被监控的主机上，zabbix agent 负责定期收集客户端本地各项数据，并发送至 zabbix server 端，zabbix server 收到数据后， 将数据存储到数据库中，用户基于 Zabbix Web 可以看到数据在前端展现图像。当 zabbix 监控某个具体的项目， 该项目会设置一个触发器阈值， 当被监控的指标超过该触发器设定的阈值，会进行一些必要的动作，动作包括：发送信息（邮件、微信、短信）、发送命令（shell 命令、reboot、restart、 install 等）
二.关于Zabbix 6.0 新特性
1.Zabbix server高可用防止硬件故障或计划维护期的停机：
- 原生选择加入HA群集配置
- 定义一个或多个备用节点
- 实时监控Zabbix server群集节点的状态
- 不需要外部工具即可将Zabbix server配置为HA群集模式
2.Zabbix 6.0 LTS新增Kubernetes监控功能在Kubernetes系统从多个维度采集指标
- Kubernetes节点和pods的自动发现和监控
- 无代理方式采集Kubernetes pods和节点的信息
- 获取Kubernetes节点主机高水平信息
3.Zabbix 6.0 功能组件
（1）Zabbix Server
- zabbix 服务端守护进程，是 Zabbix 软件的核心组件，Zabbix Agent 向其报告可用性、系统完整性信息和统计信息
- Zabbix Server 也是存储所有配置信息、统计信息和操作信息的核心存储库
- Zabbix Server 也是 Zabbix 监控系统的告警中心。在监控的系统中出现任何异常，将发出通知给管理员
- 基本的 Zabbix Server 的功能分解成为三个不同的组件。他们是：Zabbix server、Web 前端、数据库
- Zabbix 的所有配置信息都存储在 Server 和 Web 前端进行交互的数据库中。例如，当你通过 Web 前端（或者API）新增一个监控项时， 它会被添加到数据库的监控项表里。然后，Zabbix server 以每分钟一次的频率查询监控项表中的有效项，接着将它存储在 Zabbix server 中的缓存里。 这就是为什么 Zabbix 前端所做的任何更改需要花费两分钟左右才能显示在最新的数据段的原因
（2）数据库
- 所有配置信息以及 Zabbix 采集到的数据都被持久存储在数据库中
- 可以支持 MySQL、PostgreSQL、Oracle、DB2、TimescaleDB 等多种数据库
（3）Web 界面
- Web 界面是 Zabbix Server 的一部分，用于实现展示和配置的界面。通常（但不一定）和 Zabbix server 运行在同一台物理机器上
- 基于 Apache/Nginx + PHP 实现，早期只支持 LAMP 架构，从 Zabbix5.0 开始支持 LNMP
（4）Zabbix Agent
- 客户端守护进程，部署在被监控目标上，用于主动监控本地资源和应用程序，并将收集的数据发送给 Zabbix Server。从 Zabbix5.0 开始支技 Zabbix Agent2
（5）Zabbix Proxy
- zabbix 分布式代理守护进程，可以代替 Zabbix Server 采集性能和可用性数据。Zabbix Proxy 在 Zabbix 的部署是可选部分
- Zabbix Proxy 的部署可以很好的分担单个 Zabbix Server 的负载
- 通常监控大于 500 台主机时使用，需要进行分布式监控架构部署
（6）Java Gateway
- Zabbix 要监控 Tomcat 服务或其它 JAVA 程序（比例 Elasticsearch、ZooKeeper），需要使用 Java Gateway 做为代理，才能从 JAVA 程序中获取数据
三.Zabbix 6.0 部署
-
系统：CentOS 7 不支持 yum 方式安装 Zabbix 6.0 服务端
-
安装方式：Zabbix 服务端采用编译安装的方式，zabbix 客户端采用 yum 安装的方式
1.部署 zabbix 服务端
（1）关闭 selinux 与防火墙
systemctl disable --now firewalld
setenforce 0
hostnamectl set-hostname zbx-server
[root@localhost ~]# systemctl disable --now firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0
[root@localhost ~]# hostnamectl set-hostname zbx-server2.部署 Nginx + PHP 环境并测试
（1）安装 nginx
cd /etc/yum.repos.d/
vim nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
yum install -y nginx
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim nginx.repo
[root@localhost yum.repos.d]# mount /dev/sr0 /mnt
mount: /dev/sr0 写保护，将以只读方式挂载
[root@localhost yum.repos.d]# yum install -y nginx

}
（4）修改 php 配置
vim /etc/php-fpm.d/www.conf
user = nginx
group = nginx
vim /etc/php.ini

vim /var/www/zbx/index.php<?phpphpinfo();?>
（6）启动服务
systemctl enable --now nginx php-fpm
（7）测试访问（hosts解析）
修改 C:\Windows\System32\drivers\etc\hosts
192.168.80.20 moonlight
（8）浏览器访问：http://moonlight/index.php
3.部署数据库，要求 MySQL 5.7 或 Mariadb 10.5 及以上版本
（1）配置 Mariadb yum源
cd /etc/yum.repos.d/
vim mariadb.repo [mariadb]name = MariaDBbaseurl = http://mirrors.aliyun.com/mariadb/yum/10.5/centos7-amd64/gpgkey = http://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDBgpgcheck = 1enabled=1EOF
yum install -y mariadb-server mariadb
systemctl enable --now mariadb

......
[root@localhost yum.repos.d]# systemctl enable --now mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
（2）初始化数据库
mysql_secure_installation分别输入 回车 -> n -> Y (设置root密码，如abc123) -> 后面一路 Y
mysql -u root -pabc123
[root@localhost yum.repos.d]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
You already have your root account protected, so you can safely answer 'n'.
Switch to unix_socket authentication [Y/n] n... skipping.
You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
[root@localhost yum.repos.d]# mysql -u root -pabc123
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 11
Server version: 10.5.21-MariaDB MariaDB Server
......
（3）创建数据库并指定字符集
CREATE DATABASE zabbix character set utf8 collate utf8_bin;
MariaDB [(none)]> CREATE DATABASE zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.002 sec)（4）创建 zabbix 数据库用户并授权
GRANT all ON zabbix.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix';
GRANT all ON zabbix.* TO 'zabbix'@'%' IDENTIFIED BY 'zabbix';
flush privileges;
MariaDB [(none)]> GRANT all ON zabbix.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix';
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> GRANT all ON zabbix.* TO 'zabbix'@'%' IDENTIFIED BY 'zabbix';
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> quit
Bye
（5）向数据库导入 zabbix 数据（上传源码包 zabbix-6.0.13.tar.gz 到 /opt 目录）
cd /opt
tar xf zabbix-6.0.13.tar.gz
ls /opt/zabbix-6.0.13/database/mysqldata.sql double.sql history_pk_prepare.sql images.sql Makefile.am Makefile.in schema.sql
[root@localhost yum.repos.d]# cd /opt
[root@localhost opt]# tar xf zabbix-6.0.13.tar.gz
[root@localhost opt]# ls /opt/zabbix-6.0.13/database/mysql
data.sql double.sql history_pk_prepare.sql images.sql Makefile.am Makefile.in schema.sql
（6）按照顺利导入数据库
