[Nginx] CentOS 安裝網頁伺服器 Nginx

前言

相較於 Apache，Nginx 消耗資源少且處理速度快，又支援高併發，是大流量應用的好選擇。

環境

• CentOS 8.2

安裝

開啟 Terminal，使用 dnf 來安裝 Nginx

[user@localhost ~]$ sudo dnf install -y nginx
...
...
...
Complete!    #看到這就行代表完成

啟動並確認

Nginx 預設是沒有開啟的，預設當系統開機時也不會自動開啟，所以通過指令

[user@localhost ~]$ sudo systemctl start nginx   # 現在馬上開啟 nginx 服務
[user@localhost ~]$ sudo systemctl enable nginx  # 之後開機也要自動開啟 nginx 服務

確認 Nginx 的服務狀態，看到 active (running) 代表正在運行囉

[user@localhost ~]$ sudo systemctl status nginx
