Zabbix 6.0 监控部署与配置

一、Zabbix安装

# 安装Zabbix仓库
rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm

# 安装Zabbix服务器和Agent
dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf

# 安装数据库
dnf install mariadb-server
systemctl enable mariadb --now

# 创建数据库
mysql -uroot -p
CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'zabbix_password';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
FLUSH PRIVILEGES;

二、配置Zabbix服务器

# 导入数据库
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

# 配置Zabbix服务器
vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix_password

# 启动服务
systemctl enable zabbix-server --now
systemctl enable httpd --now
systemctl enable php-fpm --now

三、添加被监控主机

# 1. 在被监控主机安装Agent
dnf install zabbix-agent

# 2. 配置Agent
vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.1.100       # Zabbix服务器IP
ServerActive=192.168.1.100
Hostname=web-server-1

# 3. 启动Agent
systemctl enable zabbix-agent --now

# 4. 在Web界面添加主机
# Configuration -> Hosts -> Create host
# Host name: web-server-1
# Groups: Linux servers
# Agent interfaces: 192.168.1.10:10050

四、创建监控项和触发器

# 创建监控项 (Item)
# Configuration -> Hosts -> Items -> Create item
# Name: CPU Usage
# Key: system.cpu.util
# Type: Zabbix agent
# Update interval: 30s

# 创建触发器 (Trigger)
# Configuration -> Hosts -> Triggers -> Create trigger
# Name: CPU High Usage
# Expression: avg(/Linux server/system.cpu.util,5m)>80
# Severity: Warning

# 创建图形 (Graph)
# Configuration -> Hosts -> Graphs -> Create graph
# Add Items: CPU Usage

五、报警配置

# 配置媒介类型
# Administration -> Media types -> Email
# SMTP server: smtp.example.com
# SMTP helo: example.com
# SMTP email: zabbix@example.com

# 配置用户报警媒介
# Administration -> Users -> Media
# Add: Email: admin@example.com

# 创建动作
# Configuration -> Actions -> Trigger actions -> Create action
# Conditions: Trigger = CPU High Usage
# Operations: Send message to Admin
