环境Ubuntu安装优化安装PostgreSQL数据库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

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 

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。

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")  

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

查看日志cat /var/log/zabbix/zabbix_server.log

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```
