关于CentOS 7升级Python到3.5后，yum出现的问题。 lincanbin CentOS 7升级Python到3.5后，我跟以前CentOS 6一样，在/usr/bin/python创建了一个指向Python 3的软连接，然后将/usr/bin/yum的顶部的： !/usr/bin/python 改成了 !/usr/bin/python2.7 后，运行yum，还是出现了以下错误： [root @vps ~]# yum -y install yum-priorities Loaded plugins: fastestmirror, langpacks Determining fastest mirrors base: ftp.iij.ad.jp epel: ftp.kddilabs.jp epel-debuginfo: ftp.kddilabs.jp epel-source: ftp.kddilabs.jp extras: ftp.iij.ad.jp updates: ftp.iij.ad.jp File "/usr/libexec/urlgrabber-ext-down", line 28 except OSError, e: ^ SyntaxError: invalid syntax File "/usr/libexec/urlgrabber-ext-down",

404 when accessing Tomcat with HttpUrlConnection, 200 from browser

由 时间秒杀一切 提交于 2019-12-10 16:04:25
问题 I am getting the weirdest Tomcat error. I have a web app running on my localhost at port 8080 using tomcat and everything appears to running great, no errors etc. However, when I try to access this web app from another app using the HttpURLConnection class, I am getting a 404 error. The weird part is, when I put the same URL in the browser it returns a 200 code and has a valid response. I have tried/checked the following from these posts : post1 and post2 Setting the User Agent and Accept

How to change ngrok's web interface port address (not 4040)?

由 半城伤御伤魂 提交于 2019-12-10 14:43:21
问题 ngrok's awesome web interface is pointed to http://127.0.0.1:4040 by default. I have other applications listening on that port, however, and need to change it so that ngrok listens on, say, http://127.0.0.1:4045 . 回答1: Create a config.yml wherever ngrok is looking for its default config on your platform. If the directory doesn't exist, make it (on windows this is done by entering .ngrok2. as the folder name). OS X /Users/example/.ngrok2/ngrok.yml Linux /home/example/.ngrok2/ngrok.yml Windows

Java. InetAddress.getLocalHost returns strange IP

由 百般思念 提交于 2019-12-10 14:29:53
问题 I'm don't understand, why code below prints 0.0.9.229 instead 127.0.0.1. Can anybody tell me, hot to fix that? String ha = InetAddress.getLocalHost().getHostAddress(); System.out.println(ha); UPD: Code running on Ubuntu /etc/hosts 127.0.0.1 localhost 127.0.1.1 2533 回答1: InetAddress.getLocalHost() doesn't do what most people think that it does. It actually returns the hostname of the machine, and the IP address associated with that hostname. This may be the address used to connect to the

Using an alias for the localhost server in MySQL

由 删除回忆录丶 提交于 2019-12-10 14:10:22
问题 When I am at the office, MySQL runs on a specific server which is called "mysqldev". In my /etc/hosts file I have set "mysqldev" to match the IP of this server. So far, so good. However, when I am out of the office using my laptop, I want to use my local MySQL database, as I clone specific databases there and have no internet to connect to the office database. I do not want to change my scripts, but rather my laptop configuration. So on my laptop I have set in /etc/hosts : 127.0.0.1 localhost

Setting localhost as a Spotify redirect_uri

由 ℡╲_俬逩灬. 提交于 2019-12-10 13:46:39
问题 I've looked here on SO and I've found a few posts about redirect_uri but I can't seem to figure out how I use Localhost as my redirect uri . Hopefully anyone can explain this to me. With kind regards, 回答1: You can follow the steps described in the Spotify's Web API Beginner's Tutorial, which runs a local server and uses localhost as part of the redirect_uri . Localhost URLs are valid as redirect_uri and useful for development purposes, though once you make your project public you will need to

Service Worker not working in Offline mode with node js server

问题 I am trying to build a PWA with an offline first policy. The server for the source files is a NodeJS server . I am currently testing this on a localhost node server (not sure it has an impact ?). Service worker + caching seems fine, but in offline mode I only get the Chrome Offline Page . Let's get into details : The page which is served (through the http://localhost:8080/place/test url) has some client side JS, in which I register a Service Worker : client.js if ('serviceWorker' in navigator

WCF service endpoint localhost confusion

由 一曲冷凌霜 提交于 2019-12-10 13:17:04
问题 I'm confused as to why something works. I'm configuring a wcf service like this: <services> <service name="ClientCommand" behaviorConfiguration="SomeServiceBehavior"> <endpoint contract="IClientCommand" binding="netTcpBinding" BindingConfiguration="TcpPort" address="net.tcp://localhost:1304" /> </service> </services> The BindingConfiguration and behaviorConfiguration are very simple, just configuring some timeouts. In my exe, I start the host like this. _serverHost = new ServiceHost(type); //
