环境
- 系统:Ubuntu 20.04
- 虚拟平台:Vmware Workstation 16 PRO
- 软件版本:Zabbix 6.0 LTS
- 数据库:PostgreSQL
- Web服务:Apache
新建虚拟机(物理机跳过)
Ubuntu安装优化
安装Zabbix仓库
- wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-4%2Bubuntu20.04_all.deb
- sudo dpkg -i zabbix-release_6.0-4+ubuntu20.04_all.deb
- sudo apt update
复制代码 安装Zabbix server,Web前端,agent
- sudo apt install zabbix-server-pgsql zabbix-frontend-php php7.4-pgsql zabbix-apache-conf zabbix-sql-scripts zabbix-agent
复制代码 创建初始数据库
安装PostgreSQL数据库
- sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
- wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
- sudo apt-get update
- sudo apt-get -y install postgresql
复制代码 确保数据库服务启动并正常运行。
在数据库主机运行以下代码- sudo -u postgres createuser --pwprompt zabbix
- sudo -u postgres createdb -O zabbix zabbix
复制代码 导入初始架构和数据。- zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix
复制代码 为Zabbix server配置数据库
将password改为你设置的数据库密码。- sudo vim /etc/zabbix/zabbix_server.conf
- DBPassword=password
复制代码 启动Zabbix server和agent进程
启动Zabbix server和agent进程,并为它们设置开机自启。- sudo systemctl restart zabbix-server zabbix-agent apache2
- sudo systemctl enable zabbix-server zabbix-agent apache2
复制代码 打开Zabbix前端页面配置
虚拟机运行的可以通过ifconfig查看IP地址,并通过http://host/zabbix访问。- ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
- inet 192.168.31.193 netmask 255.255.255.0 broadcast 192.168.31.255

复制代码 选择好语言,点下一步。
检测没问题,点下一步。
输入数据库密码,点下一步。
设置Zabbix主机名称,点下一步。
点下一步,完成安装。
默认账号:Admin
默认密码:zabbix
登录
输入访问地址,账号密码,就可以正常使用Zabbix了。
使用Mariadb数据库
安装mariadb数据库(要求版本10.5以上)
Download MariaDB Server - MariaDB.org
根据文档命令进行安装
mariadb:create test file /usr/local/mysql/data/ubuntu20.lower-test
错误提示:- Jul 14 10:14:00 ubuntu20 mariadbd[2813]: 2022-07-14 10:14:00 0 [Note] /usr/sbin/mariadbd (mysqld 10.5.16-MariaDB-1:10.5.16+maria~focal-log) starting as process 2813 ...
- Jul 14 10:14:00 ubuntu20 mariadbd[2813]: 2022-07-14 10:14:00 0 [Warning] Can't create test file /usr/local/mysql/data/ubuntu20.lower-test
- Jul 14 10:14:00 ubuntu20 mariadbd[2813]: 2022-07-14 10:14:00 0 [ERROR] mariadbd: File './mysql-bin.index' not found (Errcode: 30 "Read-only file system")
复制代码 解决办法:
MariaDB cannot start after update: [Warning] Can't create test file /home/mysql/beta.lower-test
mariadb fails to start on raw drive filesystem

错误
zabbix-server 停止服务

复制代码 日志显示需要增加CacheSize的容量。
修改配置文件,增加缓存大小。
vim /etc/zabbix/zabbix_server.conf- # 根据机器配置修改容量
- CacheSize=8G```
