quid cache(简称为Squid)是一个流行的自由软件(GNU通用公共许可证)的代理服务器和Web缓存服务器。Squid有广泛的用途,从作为网页服务器的前置cache服务器缓存相关请求来提高Web服务器的速度,到为一组人共享网络资源而缓存万维网,域名系统和其他网络搜索,到通过过滤流量帮助网络安全,到局域网通过代理上网。Squid主要设计用于在Unix一类系统运行,下面我们来看看squid3(高命中率)缓存服务器配置教程。
今天对我的varnish进行了下小小的压力测试,40s里的8000并发,没有失败一个,估计还可以承受更大的并发,先不说varnish了,我最近找到个命中率很高的squid的配置文件,当然是squid3.0的配置文件,有需要的可以copy回去自己改.
系统:centos 5.x
需要的软件:squid-3.0.STABLE25.tar.gz
1.下载squid
- 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.编译squid,代码如下:
- ./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,代码如下:
- 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里的内容,代码如下:
- #accel listen port
- http_port 80 accel vhost vport
- #accel domain
- cache_peer xx.xx.xx.xx parent 80 0 no-query originserver no-digest name=a
- cache_peer_domain a www.phpfensi.com
- #acl

- cache_log /var/log/squid/cache.log
- logfile_rotate 12
- # MISCELLANEOUS

- client_db off
4.创建目录,代码如下:
- /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目录:
/usr/local/squid/sbin/squid -z
启动squid:
/usr/local/squid/sbin/squid -D
如果大家不喜欢这样的启动方式,可以自己去找个squid的启动脚本,这里就不放出了.当squid运行起来了之后,大家可以使用下面这个命令来查看命中率:
/usr/local/squid/bin/squidclient -p 80 mgr:info
好了,具体其他squid的使用命令就只能你们自己去搜了,就到这里了.
