代理访问是什么意思_国外代理服务器ip推荐

需求：需要抓到客户端访问请求的具体id和其耗时。

解决：1、使用仓库服务器中的一台虚机作为代理，让 *** 作客户端通过代理访问服务端，通过日志记录具体的请求信息和响应耗时。

在代理服务器上安装squidyum -y install squidcat >> /etc/squid/squid.conf << EOFlogformat combined %tl %6tr %>a "%rm %ru %rp HTTP/%rv" %>Hs %<st %Ss:%Sh/%<aaccess_log /var/log/squid/access.log combinedEOFsystemctl enable squid --now具体的logformat释义如下：ts Seconds since epochtu subsecond time (milliseconds)tr Response time (milliseconds)>a Client source IP addressui User name from identun A user name. Expands to the first available namefrom the following list of information sources:– authenticated user name, like %ul– user name supplied by an external ACL, like %ue– SSL client name, like %us– ident user name, like %uitl Local time. Optional strftime format argumentdefault %d/%b/%Y:%H:%M:%S %z[http::]rm Request method (GET/POST etc)[http::]ru Request URL from client (historic, filtered for logging)rp Request URL path excluding hostname[http::]rv Request protocol version[http::]>Hs HTTP status code sent to the client[http::]<st Total size of reply sent to client (after adaptation)[http::]>h Original received request header.Usually differs from the request header sent bySquid, although most fields are often preserved.Accepts optional header field name/value filterargument using name[:[separator]element] format.Ss Squid request status (TCP_MISS etc)Sh Squid hierarchy status (DEFAULT_PARENT etc)在客户端pc上设置代理服务器：l 直接搜索“代理” ，点击“代理服务器设置”。

l 打开使用代理；输入代理服务器设置10.168.79.227 3128，并保存。

关闭代理则将开关置为关即可。

l 打开客户端能进行正常 *** 作即配置成功。

在服务器上/var/log/squid/access.log的输出日志如下，通过filebeat采集到内网elk。

能通过各种维度分析请求的数据，比如分析url请求耗时的统计排序，请求耗时分布等，非常有助于分析系统问题！
