小編為您推薦: Varnish 服務器

Varnish cache是一款功能強大專業(yè)的高性能反向代理服務器和HTTP加速器的工具,幫助朋友輕松的進行http相關的加速服務器的建立,有需要這款反向代理服務器的朋友就來IT貓撲下載吧!

Varnish Cache功能特色

初步流支持,無論是在錯過和通行證

壓縮和解壓縮的支持,包括縫合在一起

壓縮ESI片段

插件(vmods)

改進的文件

參數(shù)的默認值

Varnishncsa現(xiàn)在有自定義日志格式的支持

Varnishlog,varnishncsa和varnishhist現(xiàn)在可以過濾掉的記錄

匹配多個表達式。

Varnish cache

Varnish的結構特點

Varnish把數(shù)據(jù)存放在服務器的內(nèi)存中,這種模式的效率是最高的,不過重啟后數(shù)據(jù)會消失,官方透露3.0版本可以解決這個問題。Varnish可以設置0~60秒的精確緩存時間,不過32位的機器支持的緩存文件最大為2 GB。Varnish采用VCL的配置,而且具有強大的管理功能,如top、stat、admin、lis,所以管理方式比較靈活。Varnish的狀態(tài)機設計不僅巧妙,結構也很清晰,利用二叉堆管理緩存文件,即可達到隨時刪除的目的。

與傳統(tǒng)的Squid 相比,Varnish具有性能更高、速度更快、管理更加方便等諸多優(yōu)點:

Varnish采用了“Visual Page Cache”技術,所有緩存的數(shù)據(jù)都直接從內(nèi)存讀取,而Squid從硬盤讀取緩存的數(shù)據(jù),它避免了Squid頻繁在內(nèi)存、磁盤中交換文件,性能要比Squid高。

Varnish穩(wěn)定性比Squid高,宕機率很低。

通過Varnish管理端口,可以使用正則表達式快速、批量地清除部分緩存,這一點是Squid不能具備的。

Varnish Cache使用方法

如果您是 RedHat/CentOS 系統(tǒng)想安裝 varnish,您需要安裝以下軟件包:

automake

autoconf

libtool

ncurses-devel

libxslt

groff

pcre-devel

pkgconfig

Varnish可以支持更多的并發(fā)連接。因為Varnish的TCP連接與釋放比Squid快,所以在高并發(fā)連接情況下可以支持更多的TCP連接。

以下是在配置好 yum 包管理器的情況下運行

yum install -y automake autoconf libtool ncurses-devel libxslt groff pcre-devel pkgconfig

[root@node18 ~]# yum install -y automake autoconf libtool ncurses-devel libxslt groff pcre-devel pkgconfig
