環境
- 系統：Ubuntu 20.04
- 虛擬平臺：Vmware Workstation 16 PRO
- 軟體版本：Zabbix 6.0 LTS
- 資料庫：PostgreSQL
- Web服務：Apache
新建虛擬機（物理機跳過）
安裝Zabbix倉庫
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
安裝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
創建初始資料庫
安裝PostgreSQL資料庫
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
確保資料庫服務啟動並正常運行。
在資料庫主機運行以下代碼
sudo -u postgres createuser --pwprompt zabbix
sudo -u postgres createdb -O zabbix zabbix
導入初始架構和數據。
zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix
為Zabbix server配置資料庫
將password改為你設置的資料庫密碼。
sudo vim /etc/zabbix/zabbix_server.conf
DBPassword=password
啟動Zabbix server和agent進程
啟動Zabbix server和agent進程，併為它們設置開機自啟。
sudo systemctl restart zabbix-server zabbix-agent apache2
sudo systemctl enable zabbix-server zabbix-agent apache2
打開Zabbix前端頁面配置
虛擬機運行的可以通過ifconfig查看IP地址，並通過http://host/zabbix訪問。

選擇好語言，點下一步。
檢測沒問題，點下一步。
輸入資料庫密碼，點下一步。
設置Zabbix主機名稱，點下一步。
點下一步，完成安裝。
預設賬號：Admin
預設密碼：zabbix
登錄
輸入訪問地址，賬號密碼，就可以正常使用Zabbix了。
使用Mariadb資料庫
安裝mariadb資料庫（要求版本10.5以上）
Download MariaDB Server - MariaDB.org
根據文檔命令進行安裝
mariadb：create test file /usr/local/mysql/data/ubuntu20.lower-test
錯誤提示：

解決辦法：
MariaDB cannot start after update: [Warning] Can't create test file /home/mysql/beta.lower-test
mariadb fails to start on raw drive filesystem

日誌顯示需要增加CacheSize的容量。
修改配置文件，增加緩存大小。
vim /etc/zabbix/zabbix_server.conf
# 根據機器配置修改容量
CacheSize=8G```本文來自博客園，作者：Solita1y，轉載請註明原文鏈接：https://www.cnblogs.com/solita1y/p/17153976.html
