CentOS 6.2 编译安装Squid 配置反向代理服务器

Linux操作系统:CentOS 6.2
squid安装:
1.下载squid源码安装包
wget http://www.squid-cache.org/Versions/v3/3.2/squid-3.2.3.tar.gz
解压缩
tar zxvf squid-3.2.3.tar.gz
进入解压后的目录
cd squid-3.2.3(目录位置依据个人设定而不同)
安装
[root@localhost squid-3.2.3]# ./configure –prefix=/usr/local/squid –enable-gnuregex –enable-icmp –enable-linux-netfilter –enable-default-err-language=”Simplify_Chinese” –enable-kill-parent-hack –enable-cache-digests –enable-dlmalloc –enable-poll –enable-async-io=240 –enable-delay-pools –with-filedescriptors=65536 –enable-snmp –enable-arp-acl –mandir=/usr/share/man/ –with-large-files
[root@localhost squid-3.2.3]#make && make install
如果你用的是centos系统的最小化安装,可能没有安装c语言编译器,需要手动安装,如安装过程中出现以下错误:
-bash: make: command not found
这是因为没有安装编译器,用以下命令安装:
yum install gcc* ;yum -y install gcc-*
安装后,再次make就可以。至此,squid就安装到服务器上,接下来配置反向代理。
Squid反向代理配置(如下所示):

maximum_object_size_in_memory 2048 KB
