更新時(shí)間：2014年12月31日 10:35:45 投稿：junjie

這篇文章主要介紹了squid3緩存服務(wù)器編譯安裝和高命中率配置示例,本文講解了下載squid、編譯安裝squid、配置squid等內(nèi)容,需要的朋友可以參考下

今天對(duì)我的varnish進(jìn)行了下小小的壓力測(cè)試,40s里的8000并發(fā),沒(méi)有失敗一個(gè),估計(jì)還可以承受更大的并發(fā),先不說(shuō)varnish了,我最近找到個(gè)命中率很高的squid的配置文件,當(dāng)然是squid3.0的配置文件,有需要的可以copy回去自己改。

系統(tǒng):centos 5.x
需要的軟件:squid-3.0.STABLE25.tar.gz

1.下載squid

復(fù)制代碼代碼如下:

wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE25.tar.gz

tar zxf squid-3.0.STABLE25.tar.gz && cd squid-3.0.STABLE25

2.編譯squid

復(fù)制代碼代碼如下:

./configure --prefix=/usr/local/squid \
--enable-async-io=100 \
--with-pthreads \
--enable-storeio="aufs,diskd,ufs" \
--enable-removal-policies="heap,lru" \
--enable-icmp \
--enable-delay-pools \
--enable-useragent-log \
--enable-referer-log \
--enable-kill-parent-hack \
--enable-arp-acl \
--enable-default-err-language=Simplify_Chinese \
--enable-err-languages="Simplify_Chinese English" \
--disable-poll \
--disable-wccp \
--disable-wccpv2 \
--disable-ident-lookups \
--disable-internal-dns \
--enable-basic-auth-helpers="NCSA" \
--enable-stacktrace \
--with-large-files \
--disable-mempools \
--with-filedescriptors=65536 \
--enable-ssl \
--enable-x-accelerator-var

make
make install
make install-pinger

3.配置squid

復(fù)制代碼代碼如下:

cp /usr/local/squid/etc/squid.conf /usr/local/squid/etc/squid.conf.old

>/usr/local/squid/etc/squid.conf

ln -s /usr/local/squid/etc/squid.conf /etc/squid.conf

squid.conf里的內(nèi)容:

復(fù)制代碼代碼如下:

4.創(chuàng)建目錄

復(fù)制代碼代碼如下:

/usr/sbin/groupadd squid

/usr/sbin/useradd -g squid squid

mkdir -p /var/log/squid

chown -R squid:squid /var/log/squid

mkdir -p /var/{cache1,cache2}

chown -R squid:squid /var/{cache1,cache2}

初始化squid的cache目錄

復(fù)制代碼代碼如下:

/usr/local/squid/sbin/squid -z

啟動(dòng)squid

復(fù)制代碼代碼如下:

/usr/local/squid/sbin/squid -D

如果大家不喜歡這樣的啟動(dòng)方式,可以自己去找個(gè)squid的啟動(dòng)腳本,這里就不放出了.當(dāng)squid運(yùn)行起來(lái)了之后,大家可以使用下面這個(gè)命令來(lái)查看命中率:

復(fù)制代碼代碼如下:

/usr/local/squid/bin/squidclient -p 80 mgr:info

好了,具體其他squid的使用命令就只能你們自己去搜了,就到這里了.
