Linux下使用Squid搭建代理服务器

背景介绍：

一般情况下大家会使用CCProxy搭建代理服务器，这种方法简单易用，但是也存在较多问题：1.软件受注册限制只能允许3人使用；2.CCProxy的代理请求仅支持常见的GET和POST等，对于SVN通过代理去update等请求就不支持了；3.代理的认证方式仅有基本的Basic方式，其他的ntlm等认证方式不支持等。为了能够解决以上问题，尝试使用Squid在Linux上搭建了代理服务器，分享其中的搭建方法：

一、安装Squid：

如果系统中还没有装squid，按以下顺序输入命令后即可完成安装

1. 下载Squid安装包

<code class="hljs ruleslanguage has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-array" style="word-break: break-all; box-sizing: border-box;"># wget http</span>:<span class="hljs-comment" style="word-break: break-all; color: rgb(136, 0, 0); box-sizing: border-box;">//www.squid-cache.org/Versi ... 3.0.STABLE18.tar.gz</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

2. 解压Squid安装包

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># tar -zxvf squid-3.0.STABLE18.tar.gz</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

3. 配置Squid

4. 编译

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># make</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

5. 安装

<code class="hljs ruleslanguage has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-array" style="word-break: break-all; box-sizing: border-box;"># make install</span><span class="hljs-comment" style="word-break: break-all; color: rgb(136, 0, 0); box-sizing: border-box;">//安装Squid代理软件</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

二、配置Squid

1. Squid的配置文件保存在/usr/local/squid/etc的squid.conf文件中

2. 配置Squid项：

a. 启动squid时如果不在squid.conf中设置主机名将无法启动，必须要设置visible_hostname这个参数值，本文中，设置的主机名是服务器的真实机器名powersite，在squid.conf中找到该项并修改：

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#visible_hostname linuxserver</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

b. 开启http_access的访问权限

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#http_access allow all</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

三、配置Squid的密码验证功能

1. 创建密码文件。

密码和用户名存放在/etc/squid/squid_passwd文件中，并需要将这个文件的权限设置为其它用户只读。

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># touch /etc/squid/squid_passwd</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># chmod o+r /etc/squid/squid_passwd</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">2</li></ul>

2. 使用htpasswd添加用户，并设置密码。

添加用户不需要对squid进行重启操作，我创建的用户名是setest

<code class="hljs php has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="word-break: break-all; color: rgb(136, 0, 0); box-sizing: border-box;"># htpasswd /etc/squid/squid_passwd setest</span><span class="hljs-keyword" style="word-break: break-all; color: rgb(0, 0, 136); box-sizing: border-box;">New</span>password:
Re-type password<span class="hljs-keyword" style="word-break: break-all; color: rgb(0, 0, 136); box-sizing: border-box;">for</span>user setest</code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">2</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">3</li></ul>

3. 找到ncsa_auth命令的具体位置，后面的配置需要用到绝对路径

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># which ncsa_auth</span>/usr/sbin/ncsa_auth</code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">2</li></ul>

如果找不到ncs_auth的话，可以直接去squid的压缩包解压目录中拷贝一份到/usr/sbin/ncsa_auth，例如：

<code class="hljs autohotkey has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">cp helpers/basic_auth/NCSA/ncs<span class="hljs-built_in" style="word-break: break-all; color: rgb(102, 0, 102); box-sizing: border-box;">a_auth</span>/usr/sbin/ncs<span class="hljs-built_in" style="word-break: break-all; color: rgb(102, 0, 102); box-sizing: border-box;">a_auth</span></code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li></ul>

4. 在squid.conf文件中定义验证程序了，创建名为ncsa_users的ACL并加入关键字REQUIRED来强制让Squid使用NCSA验证方法。

<code class="hljs vala has-numbering" style="word-break: break-all; line-height: normal; display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># 在squid.conf的auth_param部分添加下列内容</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span>auth_param basic program /usr/sbin/ncsa_auth /etc/squid/squid_passwd<span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># 将以下ACL添加到squid.conf的ACL配置部分</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span>acl ncsa_users proxy_auth REQUIRED<span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;"># 将这些内容添加到squid.conf的http_access配置部分</span><span class="hljs-preprocessor" style="word-break: break-all; color: rgb(68, 68, 68); box-sizing: border-box;">#</span>http_access allow ncsa_users</code><ul class="pre-numbering" style="word-break: break-all; line-height: normal; margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-color: rgb(221, 221, 221); text-align: right; background-color: rgb(238, 238, 238);"><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">1</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">2</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">3</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">4</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">5</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">6</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">7</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">8</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">9</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">10</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">11</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">12</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">13</li><li style="word-break: break-all; box-sizing: border-box; padding: 0px 5px;">14</li></ul>

四、启动Squid

1. /usr/local/squid/sbin目录下的squid为运行文件。
2. 第一次运行时，先运行squid -z创建缓存文件夹。缓存文件夹在/usr/local/squid/var下创建，因此创建缓存前还需运行chmod 777 /usr/local/squid/var给该文件夹权限。
再运行squid -d 1开启squid即可。
3. 如果要关闭squid，运行squid -k shutdown则是安全关闭。
