Nginx (engine x) 是一個高性能的HTTP和反向代理web服務器,同時也提供了IMAP/POP3/SMTP服務。Nginx是由伊戈爾·賽索耶夫爲俄羅斯訪問量第二的Rambler.ru站點(俄文:Рамблер)開發的,第一個公開版本0.1.0發佈於2004年10月4日。
Nginx是一款輕量級的Web 服務器/反向代理服務器及電子郵件(IMAP/POP3)代理服務器,在BSD-like 協議下發行。其特點是佔有內存少,併發能力強,事實上nginx的併發能力在同類型的網頁服務器中表現較好,使用nginx網站用戶有:百度、京東、新浪、網易、騰訊、淘寶等。
在centOs上,是可以直接用yum命令來安裝Nginx。
// 用yum來安裝nginx
yum install nginx -y
// 安裝完畢,啓動nginx
nginx
安裝啓動後,在chrome中輸入對應的服務器ip地址,就可以看到nginx默認頁面
在/etc/nginx/nginx.conf配置文件中配置你自己的項目目錄,並讓nginx正確訪問。
/etc/nginx/nginx.conf文件修改配置(最主要的是server { }內的內容,本人配置了四個網頁地址:訪問爲http://127.0.0.1、http://127.0.0.1/html、http://127.0.0.1/fangjiaqian、http://127.0.0.1/yoyo):

配置完成後,需要重啓nginx
// 重啓nginx
nginx -s reload
