还有个软件叫tinyproxy也很好用
有时候内网很多机器都不能上外网,只能开放几个特定ip访问外网, 那么可以在这个可以上外网的机器上面搭建代理服务器,其他机器配置好代理就能上网了。

不管是测试用途还是自己使用,squid都是一个很不错的代理工具。支持正向代理、反向代理、还有透明代理。 本篇演示搭建了一个简单的squid的正向代理,同时支持认证,随便记记笔记。

安装
yum install squid -y
yum install httpd-tools -y

生成密码文件
mkdir /etc/squid3/

xiongneng 是用户名

htpasswd -cd /etc/squid3/passwords xiongneng

提示输入密码,在这里我设的密码为 123456

注意密码不要超过8位

测试密码文件
/usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
红帽(/usr/lib64/squid/ncsa_auth /etc/squid3/passwords)

输入 用户名 密码

xiongneng 123456

提示OK说明成功,ERR是有问题,请检查一下之前步骤

OK

测试完成,crtl + c 打断

配置
vim /etc/squid/squid.conf

在最后添加

auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
红帽(auth_param basic program /usr/lib64/squid/ncsa_auth /etc/squid3/passwords)
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

这里是端口号,可以按需修改

http_port 3128 这样写会同时监听ipv6和ipv4的端口,推荐适应下面的配置方法。

http_port 0.0.0.0:3128
权限控制
squid的权限控制很灵活,具体配置方法可以参考 官方文档, 或者 Squid中文权威指南, 具体工作原理有点像iptables,用规则去卡控流量。默认的配置只能允许内网用户访问,如果有更多需求,你还可以指定很多规则!

下面是我的配置实例:

Example rule allowing access from your local networks.

Adapt to list your (internal) IP networks from where browsing

should be allowed

acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT

#

Recommended minimum Access Permission configuration:

#

Deny requests to certain unsafe ports

http_access deny !Safe_ports

Deny CONNECT to other than secure SSL ports

http_access deny CONNECT !SSL_ports

Only allow cachemgr access from localhost

http_access allow localhost manager
http_access deny manager

We strongly recommend the following be uncommented to protect innocent

web applications running on the proxy server who think the only

one who can access services on "localhost" is a local user

http_access deny to_localhost

#

INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

#

Example rule allowing access from your local networks.

Adapt localnet in the ACL section to list your (internal) IP networks

from where browsing should be allowed

http_access allow localnet
http_access allow localhost

And finally deny all other access to this proxy

http_access deny all
日志
squid的日志默认是打开的,位于目录/var/log/squid/,当然这个地址还有日志的格式都是可以完全自定义的

[root@controller161 ~]# ll /var/log/squid/
total 496
-rw-r----- 1 squid squid 355208 May 6 12:17 access.log
-rw-r----- 1 squid squid 1846 Jul 10 2016 access.log-20160710.gz
-rw-r----- 1 squid squid 3710 Jul 15 2016 access.log-20160718.gz
-rw-r----- 1 squid squid 125341 May 4 15:19 cache.log
-rw-r----- 1 squid squid 1325 Jul 9 2016 cache.log-20160710.gz
-rw-r----- 1 squid squid 1110 Jul 14 2016 cache.log-20160718.gz
启动服务

开启启动

systemctl enable squid.service

启动

systemctl start squid.service

停止

systemctl stop squid.service

重启

systemctl restart squid.service
红帽命令

开启启动

service squid enable

启动

service squid start

停止

service squid stop

重启

service squid restart

代理服务器设置
在其他CentOS机器上面配置各种代理方法

全局代理
vim /etc/profile,在最后加入

export http_proxy="http://username:password@proxy_ip:port"
export https_proxy="http://username:password@proxy_ip:port"
Copy

yum代理设置
编辑/etc/yum.conf,在最后加入

Proxy

proxy=http://username:password@proxy_ip:port/
wget的代理设置
编辑/etc/wgetrc,在最后加入

Proxy

http_proxy=http://username:password@proxy_ip:port/
https_proxy=http://username:password@proxy_ip:port/
ftp_proxy=http://username:password@proxy_ip:port/
curl的代理设置
在~/.bashrc里面增加一个别名:

alias curl="curl -x http://username:password@proxy_ip:port"
Copy

另外一种方法是编辑~/.curlrc文件 (没有就创建一个):

proxy = http://username:password@proxy_ip:port

Anaconda的代理设置
修改anaconda的配置文件,位置在path-for-install目录下.condarc文件,添加代理

1、如果公司代理不使用用户名密码

proxy_servers:
http: http://xxxx:8080
2、代理需要用户名

proxy_servers:
http: http://user:password@xxxx:8080
https: https://user:password@xxxx:8080
