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)
编译安装
./configure --prefix=/usr/local/squid --disable-carp --with-aufs-threads=32 --with-pthreads --enable-storeio='ufs,aufs,null' --enable-removal-policies='heap,lru' --enable-linux-tproxy --disable-wccp --enable-kill-parent-hack --disable-snmp --disable-poll --disable-select --enable-auth=basic --with-aio --enable-large-cache-files --enable-default-err-language=Simplify_Chinese --enable-epoll --enable-cache-digests --with-maxfd=65535
[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* gcc+* yum groupinstall 'Development Libraries' yum groupinstall 'Development Tools'
安装后,再次make就可以了。至此,squid就安装到服务器上了,接下来配置反向代理。
Squid反向代理配置:
