官网下载的windows版本，默认是要放c:\squid中，如果需要改默认路径的话，需要etc\squid.conf文件中至少增加如下配置
# Uncomment and adjust the following to add a disk cache directory. cache_dir ufs G:/apps/squid2/var/cache/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir G:/apps/squid2/var/cache/squid mime_table G:/apps/squid2/etc/mime.conf logformat squid %tl %ts.%03tu %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt logfile_daemon G:/apps/squid2/libexec/logfile-daemon.exe diskd_program G:/apps/squid2/libexec/diskd-daemon.exe unlinkd_program G:/apps/squid2/libexec/unlinkd.exe #pinger_program G:/apps/squid2/libexec/pinger.exe #cache_dns_program G:/apps/squid2/libexec/dnsserver.exe icon_directory G:/apps/squid2/share/icons error_directory G:/apps/squid2/share/errors/English cache_log G:/apps/squid2/var/logs/cache.log cache_store_log G:/apps/squid2/var/logs/store.log access_log G:/apps/squid2/var/logs/access.log squid 首次运行的时候需要手工创建cache目录 mkdirG:\apps\squid2\var\cache\squid 执行 squid.exe -fG:/apps/squid2/etc/squid.conf -z 然后执行squid.exe -fG:/apps/squid2/etc/squid.conf -i 安装windows服务，安装的时候需要使用管理员命令行窗口，否则无法安装 然后就可以使用net start squid来启动了
