基于 4 个 8 撸了一个 CDN 友好的 DNS

@q0000x 一年内不会关， prcdns 需要 Python3.5 ，我也不清楚如何安装到 openwrt 上。文档我一点点写吧。

@q0000x 可以将 114 作为备用，
server {
label = "prcdns"; //设置 PRCDNS 作为上游服务器
ip = 23.106.151.177;
timeout = 10;
port = 3535;
}
server {
label = "114dns"; //备用 114DNS 作为上游服务器
ip = 114.114.114.114,114.114.115.115;
timeout = 10;
port = 53;
}

@lbp0200 我先试试把 py 撸到 openwrt 上，如果可以再联系继续

@lbp0200 py3.4 行不行？

@q0000x 不行

@lbp0200 3.6 不知道行不行，看到你 setup 里写了 3.6 路由上已经把 3.6 的 py 撸好运行后提示

我是吧 setup.py 、 setup.config 下载到路由上执行

root@OpenWrt:~# /tmp/setup.py
/tmp/setup.py: line 2: A setuptools based setup module.
: not found
/tmp/setup.py: line 5: from: not found
/tmp/setup.py: line 6: from: not found
/tmp/setup.py: line 8: from: not found
/tmp/setup.py: line 10: syntax error: unexpected "("

@q0000x 3.6 没问题，看错误信息，可能是因为缺少 pip

@lbp0200 python3-pip 已经安装过了， python3-setuptools 这个也有

@q0000x 我也不知道了，你可以尝试修改代码

@lbp0200 问题是我不会 py...

@lbp0200 能撸个 3.4 的吗，我这个 openwrt 上只有 3.4 的能正常运行， 3.6 那个估计是不兼容

遇到一个很尴尬的问题，我在 centos7 上安装 Python3.5.1 然后 pip install PRCDNS 当我用 yum 安装 Supervisor 的时候遇到问题了 Supervisor 启动不起来
pkg_resources.DistributionNotFound: The 'supervisor==3.1.3' distribution was not found and is required by the application

搜了很久也没找到怎么解决这个问题了，然后想试试用 pip install Supervisor 得到以下结果

ollecting supervisor

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-qadut3c0/supervisor/

好像是 supervisor 不支持 python3 这就很尴尬了，怎么搞？

已经解决了，果然把默认 python 换成 3.5 不是个好主意 好多地方要把 #!/usr/bin/python 换成 #!/usr/bin/python2.7

不能支持 udp 吗？这样可以用 dnsmasq 直接访问了

@mike163 不支持

@lbp0200 话说我在你的博客上怎么找不到你的微信

直接 PRCDNS 的话就是一个光标一直在闪，不能进行任何操作了

@lbp0200 debian7 x64

@q0000x 对，这样程序就运行起来了，可以测试下，需要一直运行的话，搭配 supervisor

@lbp0200 晕，没有任何提示我还以为挂了，又重新安装环境坐等你回复呢

@lbp0200 通常情况下不关机重启不用 supervisor 也没关系吧？
