利用Nginx替代apache實現(xiàn)高性能的Web環(huán)境

1、.：.；利用Nginx替代apache實現(xiàn)高性能的Web環(huán)境利用Nginx替代apache實現(xiàn)高性能的Web環(huán)境Nginx引見:Nginx發(fā)音為engine x，是由俄羅斯人Igor Sysoev建立的工程,基于BSD答應。聽說他當初是F5的成員之一，英文主頁： HYPERLINK t _blank 。俄羅斯的一些大網(wǎng)站曾經(jīng)運用它超越兩年多了， 不斷表現(xiàn)非凡,置信想了解nginx的朋友都讀過阿葉大哥的利用nginx實現(xiàn)負載平衡的文章相關鏈接見(六)。測試環(huán)境:紅動中國(redocn)提供運營效力器環(huán)境.關于紅動效力環(huán)境:紅動中國在早期利用apache環(huán)境，再加上一些優(yōu)化的任務，不斷是相對很穩(wěn)定

2、，但是最近由于網(wǎng)站開展，訪問量越來越大，在線人數(shù)一多經(jīng)常出現(xiàn)，負載過高，性能急劇下降，經(jīng)過雙木站長的贊同，思索能否能利用nginx來替代apache，經(jīng)過長時間的察看目前nginx任務很穩(wěn)定，系統(tǒng)也不會再說現(xiàn)高負載的情況，占用內存也很低,訪問速率從用戶體驗來看明顯有提升.關于紅動中國:紅動中國redocn)論壇經(jīng)過近1年的快速開展，目前日均頁面訪問量超越100萬，位居全球設計論壇(中文)第1位，是國內最具影響力的設計論壇之一。目前論壇擁有近20萬會員，包括眾多設計界領軍人物在內的行業(yè)中堅力量、相關藝術院校師生以及部分設計喜好者等。遷移目的:實現(xiàn)網(wǎng)站論壇靜態(tài)化，防盜鏈，下載并發(fā)數(shù)和速率限制,實現(xiàn)
