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）

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

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

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

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

导入初始架构和数据。

zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix

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

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

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。

点下一步，完成安装。

默认账号：Admin

默认密码：zabbix

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：

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

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```
