squid3(高命中率)缓存服务器配置
时间:2014-12-11 23:57 来源:linux.it.net.cn 作者:IT
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
01
./configure --prefix=/usr/local/squid \
02
--enable-async-io=100 \
03
--with-pthreads \
04
--enable-storeio="aufs,diskd,ufs" \
05
--enable-removal-policies="heap,lru" \
06
--enable-icmp \
07
--enable-delay-pools \
08
--enable-useragent-log \
09
--enable-referer-log \
10
--enable-kill-parent-hack \
11
--enable-arp-acl \
12
--enable-default-err-language=Simplify_Chinese \
13
--enable-err-languages="Simplify_Chinese English" \
14
--disable-poll \
15
--disable-wccp \
16
--disable-wccpv2 \
17
--disable-ident-lookups \
18
--disable-internal-dns \
19
--enable-basic-auth-helpers="NCSA" \
20
--enable-stacktrace \
21
--with-large-files \
22
--disable-mempools \
23
--with-filedescriptors=65536 \
24
--enable-ssl \
25
--enable-x-accelerator-var
26
27
make
28
make install
29
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

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.
