Build and configure squid Proxy Server and squid Proxy Server

Build and configure squid Proxy Server and squid Proxy Server

System Environment: CentOS release 6.5 (Final) (minimal installation)

1. Install squid

# Yum-y install squid

2. Edit the configuration file (Forward proxy)

# Vim/etc/squid. conf

Add the following content:

Cache_dir ufs/var/spool/squid 1000 16 256

Cache_mem 128 MB

Refresh_pattern \. (jpg | png | gif | js | css | mp3 | mp4) 1440 20% 2880 ignore-reload

Visible_hostname rhel

Start squid service

#/Etc/init. d/squid start

Test whether the configuration is successful first in the browser:

Configure Internet Options, connections, LAN Settings, and proxy servers in the browser. Enter ip Address: 10.10.162 and port: 3128.

Use tcpdump on the squid side to check whether the squid configuration has taken effect. If a large number of data flow packets are generated, it indicates that the squid configuration is successful.

# Tcpdump-nn port 3128

Use curl for testing:

# Curl-x127.0.0.1: 3128 www.aminglinux.com-I

3. Restrict Website access

# Vim/etc/squid. conf

Add the following content:

Acl httpd proto HTTP

Acl good_domain dstdomain .baidu.com .aminglinux.com .lishiming.net

Http_access allow good_domain

Http_access deny! Good_domain

Check the syntax of the configuration file:

# Squid-kcheck

No problem restarting squid

# Service squid restart

Or reload the configuration file.

# Squid-kre
