一鍵安裝通過預設配置最省時省力地將 Plesk 伺服器安裝和運行起來。以下是具體操作步驟：
首先確認您的伺服器是否符合安裝要求： Plesk Obsidian 的軟體要求。
然後以 『root』 用戶的身份通過 SSH 登入伺服器並運行以下命令：
# sh <(curl https://autoinstall.plesk.com/one-click-installer || wget -O - https://autoinstall.plesk.com/one-click-installer)
The Plesk installation will proceed automatically. It takes, on average, around 15 minutes. The exact time can vary depending on the network bandwidth, the network speed, the server OS version, and so on.
The installer will download the latest stable Plesk release, install it with the default set of components and features designed to suit the needs of the majority of users, and apply all available patches and updates for maximum security and performance.
Do not worry that you are missing out on any Plesk features this way—you can add or remove Plesk components later. However, if you would like to have control over what components are installed, take a look at installing via console or the web GUI.
After the installation is complete, you will need to perform the post-install configuration.
