CentOS下配置Squid节点(CDN)

/usr/include/bits/typesizes.h

/usr/include/linux/posix_types.h

找到#define __FD_SETSIZE 1024

把1024改为65536

并执行

ulimit -Hs 65536

ulimit -n 65536

下载Squid

wget http://www.linuxidc.com/system/systemfiles/2010/6/squid-2.6.STABLE13.tar.gz

解压

tar zxvf squid-2.6.STABLE13.tar.gz

进入目录

cd squid-2.6.STABLE13

在configure之前先设置cflags

进入http://gentoo-wiki.com/Safe_Cflags

查看机器所用CPU对应的优化参数

用export设置

export CHOST="i686-pc-linux-gnu"

export CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"

export CXXFLAGS="${CFLAGS}"

开始configure

./configure --prefix=/usr/local/squid --enable-follow-x-forwarded-for --enable-storeio=aufs,ufs --with-maxfd=65536 --with-pthreads --enable-dlmalloc --enable-poll --enable-stacktraces --enable-removal-policies=heap,lru --enable-delay-pools

然后Make

出现

make[1]: Nothing to be done for `all-am'.

make[1]: Leaving directory `/root/squid-2.6.STABLE13'

[root@cnc squid-2.6.STABLE13]#

为Make成功

make install安装

make[2]: Leaving directory `/root/squid-2.6.STABLE13'

make[1]: Leaving directory `/root/squid-2.6.STABLE13'

[root@cnc squid-2.6.STABLE13]#

结束

如果出现报错则需要make clean再重新Make

配置Squid.conf

RM掉Squid.conf

vi squid.conf创建新文件

并把以下内容粘贴进去

保存退出

设置文件夹权限

mkdir /var/log/squid

chown nobody:nobody /var/log/squid

chown nobody:nobody /var/spool/squid

在/usr/local/squid/sbin目录下运行

./squid -z

没有报错的话说明目录创建成功

./squid -Nd 10

让Squid跑起来

curl -I http://www.6688.cc/

看一下有没有缓存

没有的话

X-Cache: MISS from 6688.cc

然后再

curl -I http://www.6688.cc/

ulimit -Hs 65536

ulimit -n 65536

./squid

上面的命令可以让Squid正式跑起来

编辑/etc/rc.local

在文件最后添加

ulimit -Hs 65536

ulimit -n 65536

/usr/local/squid/sbin/squid

让Squid随系统启动
