ipython server can't launch: No module named notebook.notebookapp

孤街醉人 提交于 2019-12-04 07:56:28
问题 I've been trying to setup an ipython server following several tutorials (since none was exactly my case). A couple days ago, I did manage to get it to the point where it was launching but then was not able to access it via url. Today it's not launching anymore and I can't find much about this specific error I get: Traceback (most recent call last): File "/usr/local/bin/ipython", line 9, in <module> load_entry_point('ipython==4.0.0-dev', 'console_scripts', 'ipython')() File "/usr/local/lib

How do multiple servers work in sync for web application?

独自空忆成欢 提交于 2019-12-04 07:53:43
问题 My first question is, I often read about people using multiple dedicated servers to run their websites, and process queries from users. But how do they exactly do this? I mean, when I enter a domain name, a DNS resolves maps that to an IP address, but I am lost after that.. is there some kind of master/slave architecture there to load balance incoming requests amongst the (potentially) hundreds of servers? If that's the case, how do the various servers, share data (database for e.g.)? Will

How to connect to a target server via SSH with a key from a GitLab pipeline?

…衆ロ難τιáo~ 提交于 2019-12-04 07:52:50
I want to connect to a server via SSH with a public key when GitLab pipeline succeeds. As I see, I need to generate a key with ssh-keygen on GitLab side and add it to server where I want to connect. I can generate a key during the pipeline but as the public key is not added to the target server, it makes no sense. I suppose it's a common scenario to connect from a CI build to a remote SSH with a key. How can I make it work? You can run ssh-keygen from wherever you want as long as you use the appropriate keys on the appropriate server. Here is what you need: Generate a key pair Copy the private

How to use the optional hostname parameter in Node.js server.listen()

倖福魔咒の 提交于 2019-12-04 07:11:44
From what I've read in tutorials so far, the optional hostname parameter to server.listen(port[, hostname][, backlog][, callback]) has always been either 127.0.0.1 (loopback), 0.0.0.0 ( listen on every available network interface, the default option ), or one of the actual IP addresses available to the server. Everything else will give an Error: listen EADDRNOTAVAIL . Is that the whole picture? (I believe hostname is technically different from IP...) I wasn't able to find out too much about it from the doc ... So, you need a resolvable DNS host name for this to work. For a quick example, I

Create Node JS Server that stores and displays data based on the day of the week

拈花ヽ惹草 提交于 2019-12-04 07:01:30
问题 I need to create a function that can display a metric pulled at different hours of the day from an outside source one week ago. The way I have my server currently set up is using a method that pulls a metric from an outside source at the hours of 6 am and 7 am. I then need to store this data for a week, and then display the data from that day starting at midnight a week from that day. I am trying to store and archive the data I collect over the course of each day so that I can reference the

PHP and ADODB connection fail

微笑、不失礼 提交于 2019-12-04 05:57:46
问题 I have been tasked to migrate servers. This includes moving over apps I did not build, a couple of which have an ADODB.connection that I cannot seem to fix on the new servers (I only get blank screens). I have researched quite extensively ADODB.connection with PHP and cannot find a definite source. Most are related to VB Script, or even Excel documents. I even searched YouTube and the only thing I found wasn't even in English. I took some of the previous developer's code and created a test
