Nginx在嘗試安裝其他軟件包時遇到問題

Question

我嘗試在我的ubuntu服務器上安裝某些應用程序，並且一直運行到像這樣的nginx問題。

我想解決這個問題。我剛開始使用nginx，所以我是新手。

這裏是 「systemctl狀態nginx.service」 結果

Answer 1

第一個日誌是說，你應該安裝以下軟件包： nginx的滿，nginx的光，nginx-臨時演員。

嘗試（使用root權限）：

apt-get install nginx-full nginx-light nginx-extras 

第二日誌說，已經被使用的端口80。你可以用命令檢查：

netstat -putan | grep 80 

所以還是有其他進程運行的是該端口或nginx的已在運行。
