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.squid-cache.org/Versions/v2/2.6/squid-2.6.STABLE13.tar.gz
解压
tar zxvf squid-2.6.STABLE13.tar.gz
**目录
cd squid-2.6.STABLE13
在configure之前先设置cflags
**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.yongchuibuxiu.cn/
看一下有没有缓存
没有的话
X-Cache: MISS from yongchuibuxiu.cn
然后再
curl -I http://www.yongchuibuxiu.cn/



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
