Nginx
    nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, originally written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VK, and Rambler. According to Netcraft, nginx served or proxied 25.64% busiest sites in April 2016. Here are some of the success stories: Netflix, Wordpress.com, FastMail.FM.
    The sources and documentation are distributed under the 2-clause BSD-like license.
    Commercial support is available from Nginx, Inc.

Nginx是一款輕量級的Web處事器/反向署理處事器及電子郵件(IMAP/POP3)署理處事器,由俄羅斯工程師Igor
Sysoev開拓,供俄國大型進(jìn)口網(wǎng)站及搜索引擎Rambler利用.其源代碼以BSD-like協(xié)議宣布.
其特點是內(nèi)存占用少,并發(fā)本領(lǐng)強,
因此被海內(nèi)許多大型網(wǎng)站(如京東/淘寶)回收.

編譯安裝

/usr/local/nginx/sbin/nginx
啟動, Nginx默認(rèn)占用80端口,可在nginx.conf中變動.

Nginx信號

關(guān)于Linux信號相關(guān)常識, 可參考系列博客Linux信號實踐, 在此, 我們僅先容Nginx捕捉的幾個信號.

nginx can be controlled with signals.

以上信號浸染亦可通過編譯出的nginx二進(jìn)制文件實現(xiàn):

To start nginx, run the executable file. Once nginx is started,
it can be controlled by invoking the executable with the -s
parameter. Use the following syntax:
nginx -s signal

Server

在Nginx內(nèi)可設(shè)置虛擬主機, 只需在nginx.conf中添加一個server元素:
