1、准备Centos环境

     groupadd squid

     useradd -s /sbin/nologin -d /dev/null -g squid squid

     mkdir /dev/shm/tmp

     chmod 1777 /dev/shm/tmp

     mount --bind /dev/shm/tmp

2、安装squid

 

./configure --prefix=/usr/squid /
--enable-debug-cbdata /
--enable-async-io=100 /
--with-pthreads /
--enable-storeio="aufs,diskd,ufs" /
--enable-removal-policies="heap,lru" /
--enable-icmp /
--enable-delay-pools /
--enable-useragent-log /
--enable-referer-log /
--enable-kill-parent-hack /
--enable-arp-acl /
--enable-default-err-language=Simplify_Chinese /
--enable-err-languages="Simplify_Chinese English" /
--disable-poll /
--disable-wccp /
--disable-wccpv2 /
--disable-ident-lookups /
--disable-internal-dns /
--enable-basic-auth-helpers="NCSA" /
--enable-stacktrace /
--with-large-files /
--disable-mempools /
--with-filedescriptors=65535 /
--enable-ssl /
--enable-x-accelerator-var
make
make install
