I am developing an app using ExtJS 7 and have a team of developers.
Each user is getting their external API's from a different source, i.e some localhost, some 192.168.1.100 etc etc
Is it possible to write something like an env file that each developer can add to their directory root and then I can pull in a variable into the app?
There is a way in pretty much every other system these days, but it seems Ext doesnt do this apart from hardcoding the value into the app.json but as this is committed to source control, it gets really messy
Something simple like
API_URL=https://localhost/api
If anyone has developed something like this, could they please share, I haven't been able to find anything
Just let them setup a common local development host-name, either in /etc/hosts or C:\Windows\System32\Drivers\etc\hosts. This file is being queried, before any DNS server will be queried - so it could even be the host-name of the public API, which still would resolve locally.
127.0.0.1 localhost
# 127.0.0.1 api.local
192.168.1.100 api.local

I have configured Nginx with autoindex module to enable Directory Listing. But I want to extend this feature to enable file editing as well and saving it.
The thing is I have some Private IPs which needs to be monitored and I have added those IPs in a file and made a script to take IPs from the file and monitor them by Pinging. Since sometimes these IPs change due to DHCP, Apart from System Admins, No one is much proficient in using Terminal. Hence I wanted to provide a webUI, so that concerned persons change this IP whenever through webpage. I know this can be possible using code, but since am not a developer, I was finding a way through here. Is it possible?
No, it's not possible using nginx alone.
I'm new to OFBiz and having trouble making it work on production. I'd appreciate it very much if you could help me to narrow down or even better solve the problem :-)
I was able to able to run OFbiz successfully at localhost and access data that came with the project (ex: https://localhost:8443/webtools/control/entitymaint)
I went through the steps setting up SSL for the project on production site on my Windows Server (I was able to access https://www.mywebsitedomain.com)
I created a folder called ROOT and put the OFBiz folder(same folder on my localhost) in the ROOT folder
I also have set up an SSL Certificate, then added the following to server.xml under Tomcat 9.
(Connector port="8443" maxThreads="150"
scheme="https" secure="true" SSLEnabled="true"
keystoreFile="C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\apache-ofbiz-17.12.03\keystore.jks" keystorePass="Password"
clientAuth="false" sslProtocol="TLS")
(/Connector)
When running https://www.mywebsitedomain/webtools/control/entitymaint(same URL except for localhost), I got the message.
"404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable."
Edit: Add some additional information
I found the following information on the OFBiz Production SetUP page:
"Configure the ofbiz-containers.xml file to point to your new keystore and password:
If using Tomcat (Catalina), which is the default, find the "catalina-container" -> "https-connector" -> "keystoreFile" and "keystorePass" properties and set them."
I go to apache-ofbiz-17.12.03\framework\base\config\ofbiz-containers.xml
All the entries I have are below. I don't know where I can add "keystoreFile" and "keystorePass" properties
<ofbiz-containers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/ofbiz-containers.xsd">
<!-- load the ofbiz component container (always first) -->
<container name="component-container" loaders="main,rmi,load-data,test" class="org.apache.ofbiz.base.container.ComponentContainer"/>
Thanks in advance.

As you found, OFBiz uses an embedded Tomcat (9.0.31). So server.xml is of no help. This wiki page needed update, done. The file you are looking for is framework\catalina\ofbiz-component.xml.
But I'm not sure you are going the right way doing this. Most of the time, it's easier to use Apache HTTPD, even on Windows. You may refer to https://s.apache.org/vmemj. Also for certificates Let's encrypt is what we use for our demos. It's free and, apart the renewal every 3 months, it's great. With their cerbot that's even not a big deal.
By and large, you should better ask questions in the OFBiz user Mailing List.You need to subscribe, please see https://ofbiz.apache.org/mailing-lists.html

In point 4 you speak about the following, but I see nothing, do I miss something?
You could also ditch OFBiz and migrate to the awesome Scipio ERP (based on the same foundation): www.scipioerp.com
We have a documentation on exactly your question right here: https://www.scipioerp.com/community/developer/installation-configuration/clustering/webserver-configuration/
I created a couchDB on my computer, that is I used the Python line server = couchdb.Server('http://localhost:5984')
I want to share this database with two other colleagues. How can I make it available to them? For the moment, I am comfortable giving them full admin privileges until I get a better handle on this.
I tried to read the relevant parts of CouchDB: The Definitive Guide, but I still don't get it.
How would they access it? They can't just type in my computer's IP address?
In order to avoid NAT problems, I would use an external service like Cloudant or Iris Couch. You can replicate your local database against the common DB in the cloud and your colleagues can connect to it.
sure they can.
Start your server like this:
server = couchdb.Server('http://192.168.56.1:5984')
Where the IP address is the IP address of your PC. Find this out via the cmd prompt and ipconfig. Then they type in their python console
server = couchdb.Server('http://192.168.56.1:5984')
Yep, exactly the same. The IP identifies it for both you and everyone else. If you want them to access it in a browser then I guess you'll need to write that front end however.
If you are not on the same local network the the same more or less applies, except you'll have to add port forwarding into the mix.
I would use ngrok (https://ngrok.com/) its free and it will expose your localhost to colleagues in order to access the db.
once you download and execute, in the command line type ngrok http 192.168.56.1:5984 and they should be able to access it when you provide them the url ngrok returns, which exposes your localhost externally
i am trying to figure this out for a long time now, but so far no luck, maybe somebody can help me.
I have a 2.2.2 cakephp installed on my computer (localhost) and everything works perfectly. But now i want that same project to be online on remote server. I upload everything, set mysql path but i get a blank page when trying to access the site.
If i upload a fresh cakephp it works, but my project doesnt. The debug is set to default, think that should be 2? I also deleted files in cache/tmp, but still no errors or anything, just blank page.
Any info would be helpful, thank you.
I hate when that happens :). Usually it does if there is an error somewhere and you can't see it because the errors are turned off, so you should call phpinfo() and see if display_errors is on. Changing the debug mode doesn't work every time since display_errors is set from php.ini.
Unfortunately, if this is the problem and you don't have access to edit the php.ini file, you might need to ask the hosting provider to change it and restart the php service.
You can also try this: error_reporting(E_ALL)
I uploaded changes to my cakephp website and discovered that all actions for a particular controller returned a blank page. I discovered what the error was and was able to reproduce it with another controller.
The problem was that in the first line of my controller file I had a space before the opening php tag.
One space cost me hours.
Just uploading all files won't cut it. Make sure you work through this checklist:
First and foremost, check the error log file located under app/tmp/logs/error.log, this usually holds some very good pointers as to what is wrong.
Make sure you have uploaded the app/Config/database.php file with the proper details. Local installs usually have user root without password. Online servers (obviously) do not!
To that extent, also make sure you actually have a database with your hosting provider (either your host sent you the info or you need to create it yourself using their control panel).
Make sure you also uploaded all .htaccess files (the one under the root directory and /app and /app/webroot), some FTP programs don't show this "hidden" file by default.
If all else fails, contact your hosting provider for further support as they usually have access to more verbose server logs that can also hold clues.
The real problem was only the coding I used in notepad++. All my files were encoded with UTF-8, but they should have been UTF-8 without BOM. After I changed it to UTF-8 withot BOM, everything started to work perfectly.
OK, so I did the dumb thing and released production code (C#, VS2010) that targeted our development database (SQL Server 2008 R2). Luckily we are not using the production database yet so I didn't have the pain of trying to recover and synchronize everything...
But, I want to prevent this from happening again when it could be much more painful. My idea is to add a table I can query at startup and determine what database I am connected to by the value returned. Production would return "PROD" and dev and test would return other values, for example.
If it makes any difference, the application talks to a WCF service to access the database so I have endpoints in the config file, not actual connection strings.
Does this make sense? How have others addressed this problem?
Thanks,
Dave
The easiest way to solve this is to not have access to production accounts. Those are stored in the Machine.config file for our .net applications. In non-.net applications this is easily duplicated, by having a config file in a common location, or (dare I say) a registry entry which holds the account information.
Most of our servers are accessed through aliases too, so no one really needs to change the connection string from environment to environment. Just grab the user from the config and the server alias in the hosts file points you to the correct server. This also removes the headache from us having to update all our config files when we switch db instances (change hardware etc.)
So even with the click once deployment and the end points. You can publish the a new endpoint URI in a machine config on the end users desktop (I'm assuming this is an internal application), and then reference that in the code.
If you absolutely can't do this, as this might be a lot of work (last place I worked had 2000 call center people, so this push was a lot more difficult, but still possible). You can always have an automated build server setup which modifies the app.config file for you as a last step of building the application for you. You then ALWAYS publish the compiled code from the automated build server. Never have the change in the app.config for something like this be a manual step in the developer's process. This will always lead to problems at some point.
Now if none of this works, your final option (done this one too), which I hated, but it worked is to look up the value off of a mapped drive. Essentially, everyone in the company has a mapped drive to say R:. This is where you have your production configuration files etc. The prod account people map to one drive location with the production values, and the devs etc. map to another with the development values. I hate this option compared to the others, but it works, and it can save you in a pinch with others become tedious and difficult (due to say office politics, setting up a build server etc.).
I'm assuming your production server has a different name than your development server, so you could simply SELECT ##SERVERNAME AS ServerName.
Not sure if this answer helps you in a assumed .net environment, but within a *nix/PHP environment, this is how I handle the same situation.
OK, so I did the dumb thing and released production code
There are a times where some app behavior is environment dependent, as you eluded to. In order to provide this ability to check between development and production environments I added the following line to global /etc/profile/profile.d/custom.sh config (CentOS):
SERVICE_ENV=dev
And in code I have a wrapper method which will grab an environment variable based on name and localize it's value making it accessible to my application code. Below is a snippet demonstrating how to check the current environment and react accordingly (in PHP):
public function __call($method, $params)
{
// Reduce chatter on production envs
// Only display debug messages if override told us to
if (($method === 'debug') &&
(CoreLib_Api_Environment_Package::getValue(CoreLib_Api_Environment::VAR_LABEL_SERVICE) === CoreLib_Api_Environment::PROD) &&
(!in_array(CoreLib_Api_Log::DEBUG_ON_PROD_OVERRIDE, $params))) {
return;
}
}
Remember, you don't want to pepper your application logic with environment checks, save for a few extreme use cases as demonstrated with snippet. Rather you should be controlling access to your production databases using DNS. For example, within your development environment the following db hostname mydatabase-db would resolve to a local server instead of your actual production server. And when you push your code to the production environment, your DNS will correctly resolve the hostname, so your code should "just work" without any environment checks.
After hours of wading through textbooks and tutorials on MSBuild and app.config manipulation, I stumbled across something called SlowCheetah - XML Transforms http://visualstudiogallery.msdn.microsoft.com/69023d00-a4f9-4a34-a6cd-7e854ba318b5 that did what I needed it to do in less than hour after first stumbling across it. Definitely recommended! From the article:
This package enables you to transform your app.config or any other XML file based on the build configuration. It also adds additional tooling to help you create XML transforms.
This package is created by Sayed Ibrahim Hashimi, Chuck England and Bill Heibert, the same Hashimi who authored THE book on MSBuild. If you're looking for a simple ubiquitous way to transform your app.config, web.config or any other XML fie based on the build configuration, look no further -- this VS package will do the job.
Yeah I know I answered my own question but I already gave points to the answer that eventually pointed me to the real answer. Now I need to go back and edit the question based on my new understanding of the problem...

I' assuming yout production serveur has a different ip address. You can simply use
SELECT CONNECTIONPROPERTY('local_net_address') AS local_net_address
