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
./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
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:
#accel listen port

4.创建目录
/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.
