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。
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。
.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。
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
和
http_access allow ubuntu
然后我就做了systemctl start squid.service
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

# And finally deny all other access to this proxy
http_access deny all
# Squid normally listens to port 3128

# Uncomment and adjust the following to add a disk cache directory.

# Leave coredumps in the first cache dir

#
# Add any of your own refresh_pattern entries above these.

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。
