利用squid给公司内网加速..

公司里的编辑 和 监控人员的工作就是天天再刷帖~~ 一个帖里面又有很多图片罗。 导致公司内部网络 有点牛车。。所以很需要我在公司内部的服务器上做一个 内部CDN 。针对公司的网站进行前端CACHE。 这样的话~~ 哇咔咔 公司内部网速就快罗

还是进行简单的安装吧。

Feebsd 系统

#/usr/ports/www/squid
# make install clean

# echo "squid_user=root" >> /etc/rc.conf 因为要启动 80端口 1024口以下的都必须 root 权限才行啦
# echo "squid_enable=yes" >> /etc/rc.conf

启动前创建存储目录：

/usr/local/sbin/squid -z

squid 的配置：

http_port 80 vhost vport
dns_nameservers 202.103.224.68 202.103.224.69
visible_hostname beihai365
cache_dir ufs /var/spool/squid 2048 16 256
cache_mem 1000 MB
cache_mgr [e-mail]
redirect_children 30
cache_access_log /var/log/squid/access.log
cache_log /var/log/squid/cache.log
cache_store_log /var/log/squid/store.log
cache_peer 222.216.28.180 parent 80 0 no-query originserver name=edns
cache_peer 222.216.28.226 parent 80 0 no-query originserver name=img
cache_peer_domain edns www.beihai365.com
cache_peer_domain img img.beihai365.com
acl webserver dst 222.216.28.180
acl imgserver dst 222.216.28.226
http_access allow imgserver
http_access allow webserver

因为只是测试。我没有给内部的DNS 做 zone 。所以暂时现在hosts文件里面进行 域名映射先。

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
127.0.0.1       localhost
192.168.1.241	www.beihai365.com
192.168.1.241	img.beihai365.com

好了。开始刷新网站。然后看下是否有 HIT 还是 MISS .. 用 firebug 看也行 看 x-cache 标记. 如下：

X-Cache	HIT from beihai365
Via	1.0 beihai365 (squid/3.0.STABLE25)

看到就知道 是经过了 CDN 处理了 而且 命中了

没有 firebug 的朋友就直接看日志啦

beihai365test# cat /var/log/squid/access.log | grep '329_437921_c975259b1f1ed19'
1299919890.545   5074 192.168.1.238 TCP_MISS/200 380347 GET http://img.beihai365.com/bbs/Mon_1103/329_437921_c975259b1f1ed19.jpg - FIRST_UP_PARENT/img image/jpeg

哦也~~ 准备整合到 内部 DNS 里面去~~
