We have a Virtuoso installation on an AWS VM, working on default port 8890, that we would like to create a subdomain, e.g., rdf.example.com:8890. The problem is that the guy that is responsible for the subdomains created a record on the service we use (don't know which), but it is not working.
Is there something that needs to be done in order for virtuoso to work under a subdomain?
I used the AWS's Route53, with no luck as well.
Seems you want to setup a multi-homing setup for hosting multiple subdomains on the same Virtuoso instance, which Virtuoso supports as in the link above.
Failing that I would suggest posting your question on the OpenLink Community Forum, to get more expert responses ...

I have tried various ways which is available on stack overflow but not single one works .i was getting error everytime whenever i tried to register my gitlab runner everytime please provide descriptive answer
error: first path segment in URL cannot contain colon error
Since you did not provide a description of your setup, it is hard to pin down the problem. I'm also not an expert on GitLab and I just recently started tinkering around with my own local GitLab instance installed via Docker.
For me I wanted to connect a GitLab-Runner to my GitLab in the local network. That's where I tumbled upon the error you are mentioning. I am using a different port for the GitLab server, which was neccessary because some other services are already using the default ports. The solution for me was to add the prefix http:// in front of the ip. After that, the registration went flawlessly.
So instead of writing for example
123.456.789.XXX:YYYY
I had to write
http://123.456.789.XXX:YYYY
Of course the ip can be different according to your network.
If you provide more information, it would be easier to solve your problem.
And in case you solved it on your own, feel free to share your solution.
Finally i completed my first full project using server, client, data
i would like to know few things about how to host and upload full website include(server ,react, mysql)
i so wondering how that is work, for now i understand that to upload a simple website you need a domain and to hosting, just do npm run build and upload it..., this is something that i know but, when that is not just a simple website like
when i have such as
server side with Node.js + express that have requests (on localhost) *probably need to change the localhost to something else but what
Database running with MySql
React app that have many request to (localhost)
how can i hosting all of them and running my website for everyone, i mean that my sql will still running, CRUD Data will update normal, and the server will still get request and send or update them to mysql data.
and if I'll want to make some change on mysql, server, client
i want to change it like i change it now
Actually i'm not a FullStack developer if i don’t know it... 🥶 so i really interesting to understand all of that issues
i hope you guys havק An understandable answer for me, thanks 🙏 and just take your time :)
Well, where to start hehe. There are a lot of different ways to host a web app. Heroku for example makes this process really simple.
Personally, I use Digital Ocean to host my apps. This is generally how that goes:
I have a project with a folder structure that seperates the server logic and the client logic.
Since you're using Node, you build your client with npm run build. Next make sure the dist/build folder is inside your server folder. That is the folder you are going to 'host'. On Digital Ocean, you make a new droplet (which basically is just a tiny part of a server).
You install Node, Git, Pm2 and (for example) Nginx. You clone your project from Github to the server and install all the dependencies.
You have to do a few configurations with nginx (specifying a domain name for example) to make everything work. This article goes into more detail about that.
Also, a database is frequently hosted seperately. You should read more about that.
If you have everything setup, you can just code on your project as usual. Push new updates to github, and pull in the changes on the server.
Here is another post on Stackoverflow talking about hosting MySql with react.
My Laravel database got hacked for the second time. the hacker deleted all tables and left a table threatening to delete it If I didn't send bitcoin. That's not a problem since I do have a backup but what can I do to prevent it?
This is for Laravel 6. the first time I had debugging mode ON in the .env file so I thought this might be the problem. after turning debugging off I still got hacked am I missing anything?
Hello Mohamed Elmoniry,
I would check your server database configuration for the following security settings I mean this is pretty basic and normally done automatically if you are not self hosting and using a service like forge or digital ocean, but here you go:
Update the password plugin
Change the root password
Remove anonymous users
Disallow remote root login
Remove test database
If you are new to this and you are using MYSQL on your server you can run the following command/script that will automatically guide you through that process
sudo mysql_secure_installation
Additionally:
If you are using a web server I would also enable SSH and deactivate password login.
If you are using a firewall I would check that only the necessary ports to your application are allowed by the UTM (Unified threat management) if it is a hardware firewall. (same applies to a software firewall)
It would be great if you know how the hacker got into the database. Maybe you have an old database version? Maybe you have an easy-to-crack password and have exposed your database to the internet. Laravel by default blocks SQL injection, so that can't be it.
If you have exposed your database, a good first step is to block all requests and allow only ones from certain IP addresses, like your server and IP addresses where you often work. This way, hackers can only get to your database if they are on one of those IP's.
Do you publish your code to GitHub? Maybe the hacker got the password from your repository (this is only possible if this is public). You should make sure you NEVER EVER publish your .env file to the internet and only keep local copies.
But the best solution would be to find out how he got in. Then you can block that entrance. You should certainly check your database version and update it if necessary.
it seems your website has some shell (malware) stored. Virus take palace with following reasons :
Old version framework (but you are using v6, that is updated)
A shell/virus already in code (check if a php shell exist, & scan with antivirus)
You have public git repo, where attacker placed his malware
You have credentials hardcoded that leaked, either through git repo or JS files.
You have unrestricted file upload option in your code, which allow hacker to upload shell.
your database server is publicly exposed,allowing anyone to access.
If you are using older jenkins or other automation tool, which exploit used.
SQL injection, (check logs)
Thanks, Jaikey
Check whether your .env or .env.sample files expose to public for some reason?
https://yourdomain.com/system/.env
If yes, block the public access of .env by adding the code below to the .htaccess file.
<FilesMatch "^\.env">
Order allow,deny
Deny from all
</FilesMatch>
This may sound like a silly question, but my client had me working on a dev version of his website, and now wants me to push changes to the live AWS server.
He's given me access, however I can't for the life of me find the MySQL database in AWS. I am given to understand it should be located under RDS but there seems to be nothing there:
Can someone tell me where to find it then? Did the client send me to the wrong server or something? He is not technical at all so not of any help.
You can use the tag editor to find all the resources that are running in the aws account (which can be tagged). Go to the tag editor and then select all region and resources to see where the db is running. Maybe its running under some other region and you are looking in the wrong region. Hope that helps
I need to make a development version of a cakePHP app with its own db so that a developer can work on it without disturbing the current users.
I thought it would be simple, I just copied the entire director /project to /project_dev and then copied the DB "project_db" to "project_db_dev". Then I went into /project_dev/config/database.php and changed the db to "project_db_dev".
When I went to see what I had done, I saw the app was still connecting to the same db, as if I'd changed nothing. I realized that the original folder name was referenced in /app/webroot/.htaccess so do I need to find/replace all instances of that folder name?
What steps should I follow to duplicate an existing cakePHP app?
You need to setup some kind of development lifecycle.
Generally speaking the developer shouldn't be doing any development on the server. The best way to handle it is locally using a stack of some kind such as Lamp (Linux, Apache, Mysql, PHP) switch out linux with other OS's. There are multiple cloud solution to these environments to such as Koding.com
Using something like Git for version control the developer can develop locally then push the code through to the server after is being thoroughly tested locally or on a dev server or some kind.
Keeping Dev work and Live work away from each other is key.
Could do with a bit more information.
If both databases are hosted on the same server and you have permission to access them both with the same user then all you have to do is change the name of the database in your database.php
If not you will also have to update the IP and any other additional settings port etc.
