cent os 上的 Squid 代理会阻止一切

问题描述 投票:0回答:1

当我在 centos 7 虚拟机上安装鱿鱼转发代理,然后告诉 ubuntu 虚拟机使用 centos 虚拟机作为代理时,鱿鱼会阻止一切,即使我创建一个新的 centos 虚拟机并安装新版本的鱿鱼,也会发生这种情况。如果我不对鱿鱼进行任何更改,问题仍然存在。我在 esxi 8 中创建了这些虚拟机

我尝试在squid.conf文件中写入http_access允许所有。

centos squid esxi

你可以发布你的配置吗?您是否在启用了

SELinux
的 CentOS 7 上使用 Squid?执行命令
getenforce
即可找出答案。如果其输出显示
Enforcing
,则 SELinux 已启用,您应该与 Squid 进行交互(启动/停止/进行更改)与 RedHat 文档指定的方式相同

使用 Squid,您应该在引用您的 Ubuntu 服务器 IP 的配置中添加新的 acl
示例:

acl ubuntu src 216.128.143.117/32

然后,您应该添加一个新的 http_access 指令,允许您的 acl 访问 Squid。
示例:

http_access allow ubuntu

在 Ubuntu 上,您可以通过以下方式启用 http/s 代理:
export http_proxy="http://{host}:{port}/"

 用于 http 代理,并且

export https_proxy="https://{host}:{port}/"
 用于 https 代理。
这会将所有 http 和 https 请求转发到指定的服务器。

将这些指令添加到用户

.bashrc

 文件中,使其对 
that 用户永久生效,或将它们添加到 /etc/environment
 中,使其在系统范围内永久生效。



如果您仍然遇到困难,我自己测试了它并在几分钟内就开始工作了。

我在德克萨斯州达拉斯的 Vultr 上部署了 2 台服务器:
一个正在运行
CentOS 7 SELinux

,另一个 
Ubuntu 22.04 LTS

在CentOS服务器上,我做了以下操作:


sudo yum update



sudo yum install squid


sudo firewall-cmd --add-port=3128/tcp --permanent


sudo firewall-cmd --reload


nano /etc/squid/squid.conf
并补充:

acl ubuntu src 216.128.143.117/32
http_access allow ubuntu

然后我就做了
systemctl start squid.service

我的

squid.conf

看起来像这样:

# # Recommended minimum configuration: # # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed ########## acl ubuntu src 216.128.143.117/32 ########## 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 ########## http_access allow ubuntu ########## # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # # Add any of your own refresh_pattern entries above these. # refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320
在 Ubuntu 服务器上,我做了:


sudo apt-get update



export http_proxy="http://216.128.131.111:3128/"


export https_proxy="https://216.128.131.111:3128/"

然后我做了 
curl ipinfo.io/ip
,响应是 
216.128.131.111
,我的 CentOS 服务器 ip。
