squid安装笔记

一、安装

wget http://www.squid-cache.org/Versions/v2/2.5/squid-2.5.STABLE13.tar.gz tar zxf squid-2.5.STABLE13.tar.gz cd squid-2.5.STABLE13 ./configure –prefix=/usr/local make make install vi /usr/local/squid/etc/squid.conf mkdir /var/squid/cache chown -R nobody:nobody /var/squid/cache chmod 0777 /var/squid/cache -R /usr/local/squid/sbin/squid -z /usr/local/squid/sbin/squid -NCd1

 

二、配置文件

# 默认端口 http_port 80 # 缓存暂用内存大小 cache_mem 512 MB maximum_object_size_in_memory 4128 KB # 缓存目录,及其大小 cache_dir ufs /var/squid/cache 2048 16 256 # 关闭访问日志 cache_access_log none cache_log none cache_store_log none auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off #hierarchy_stoplist cgi-bin admin # 禁止缓存策略 acl nocache urlpath_regex cookie.*/.php no_cache deny nocache # 缓存更新策略 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i /.xml 60 20% 440 ignore-reload refresh_pattern -i /.jpg 60 20% 440 ignore-reload refresh_pattern -i /.css 60 20% 440 ignore-reload refresh_pattern -i /.js 60 20% 440 ignore-reload refresh_pattern -i /.gif 60 20% 440 ignore-reload refresh_pattern -i /.png 60 20% 440 ignore-reload refresh_pattern -i /.html 5 20% 60 ignore-reload refresh_pattern -i /.exe 60 20% 440 ignore-reload refresh_pattern -i /.mp3 60 20% 440 ignore-reload refresh_pattern -i /.php 5 20% 440 ignore-reload refresh_pattern . 5 20% 30 # 访问策略 acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 acl Self referer_regex -i ^http://blog/.yening/.cn$ acl has_referer referer_regex . acl purge method PURGE acl CONNECT method CONNECT acl www_visitor dstdomain .win .yening.cn .verycd.com acl OverConnLimit maxconn 30 acl Purge method PURGE http_access allow Purge http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny OverConnLimit http_access allow www_visitor http_access allow Self http_access deny !has_referer http_access deny all http_reply_access allow all icp_access allow all visible_hostname onion httpd_accel_host virtual httpd_accel_port 80 httpd_accel_uses_host_header on coredump_dir /var/squid/cache

 

三、其它

linux有同时打开文件数限制,在访问量比较大的网站需要使用ulimit 增加同时打开文件数数.

ulimit 65533
/usr/local/sbin/squid -V

重新读取配置文件而不关闭squid.

/usr/local/sbin/squid -k reconfigure
