收集整理的這篇文章主要介紹了
Nginx Web服务应用
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
Nginx（“engine x”）是一個開源的，支持高性能、高并發(fā)的WWW服務(wù)和代理服務(wù)軟件。它還具有反向代理負載均衡功能和緩存服務(wù)功能。
?
1 Nginx的幾個常見的重要特性
1、支持高并發(fā)：能支持幾萬并發(fā)連接（特別是靜態(tài)小文件業(yè)務(wù)環(huán)境）
2、資源消耗少：在3萬并發(fā)連接下，開啟10個Nginx線程消耗的內(nèi)存不到200MB
3、可以做HTTP反向代理及加速緩存，即負載均衡功能，內(nèi)置對RS節(jié)點服務(wù)器健康檢查功能，這相當于專業(yè)的Haproxy軟件或LVS的功能
4、具備Squid等專業(yè)緩存軟件等的緩存功能
5、支持異步網(wǎng)絡(luò)I/O事件模型epoll（linux2.6+）
2 Nginx軟件的主要企業(yè)功能應(yīng)用
1）作為web服務(wù)軟件
支持高性能、高并發(fā)，與Apache相比，Nginx能夠支持更多的并發(fā)連接訪問，但占用的資源卻更少，效率更高，幾乎不遜色于Apache
2）反向代理或負載均衡服務(wù)
在方向代理或負載均衡服務(wù)方面，Nginx可以作為web服務(wù)、PHP等動態(tài)服務(wù)及Memcached緩存的代理服務(wù)器，它具有類似專業(yè)反向代理軟件（如Haproxy）的功能，也是一個郵件代理服務(wù)軟件，支持TCP的代理。
3）前端業(yè)務(wù)數(shù)據(jù)緩存服務(wù)
在web緩存服務(wù)方面，Nginx可以通過自身的proxy_cache模塊實現(xiàn)類Squid等專業(yè)緩存軟件的功能
3 Nginx Web服務(wù)
3.1 Nginx Web服務(wù)介紹
作為web服務(wù)器的主要應(yīng)用場景：
1）使用Nginx運行HTML、JS、CSS、小圖片等靜態(tài)數(shù)據(jù)（類似Lighttpd）
2）Nginx結(jié)合FastCGI運行PHP等動態(tài)程序（使用fastcgi_pass方式）
3）Nginx結(jié)合Tomcat/Resin等支持Java動態(tài)程序（常用proxy_pass方式）
3.2 為什么Nginx總體性能比Apache高
Nginx使用epoll和kqueue（freebsd）異步網(wǎng)絡(luò)I/O模型，而Apache使用的是傳統(tǒng)的select模型。目前Linux下能夠承受高并發(fā)訪問的Squid、Memcached軟件采用的都是epoll模型
處理大量連接的讀寫時，select網(wǎng)絡(luò)I/O模型比較低效。而epoll卻很高效
宿管比喻：
Select：帶著你到各個房間挨個去找人，知道找到人為止。
Epoll：會先記下每個人住的房間號，當你找人時，只需要告訴你住哪個房間即可，不用親自帶著你滿宿舍樓找人了。
如果同時來了100個人找人，效率差別就很明顯了。
3.3 如何正確選擇web服務(wù)器
靜態(tài)業(yè)務(wù)：若是高并發(fā)場景，盡量采用Nginx或Lighttpd，二者首選Ngingx
動態(tài)業(yè)務(wù)：理論上采用Nginx和Apache均可，建議選擇Nginx，為了避免相同業(yè)務(wù)的服務(wù)軟件多樣化，增加維護成本。動態(tài)業(yè)務(wù)可以由Nginx兼做前端代理，再轉(zhuǎn)發(fā)到后端相應(yīng)的服務(wù)器進行處理。
既有靜態(tài)業(yè)務(wù)又有動態(tài)業(yè)務(wù)：采用Nginx
如果并發(fā)不是很大，又對Apache熟悉，也可以選擇Apache，總之選擇熟悉的。
4 編譯安裝Nginx
