A weird question

Hello. I had to use VPS on my site, then I bought one, but I have no idea on how to install and configure. So, a guy that I know (not in person) installed and configured everything for me, he is really good at it, its his job.
Everything is running fine, but I´m kinda affraid.. what if, after he sees how much money im making, he copies everything on my site, create another one and delete mine?

So the question is:

What do I need to change, like password, port, etc, to make it completely secure?

Here is what he installed:
Nginx, php, php-fpm, mysql (I´m using wordpress), ssh, ftp.


What I´m looking for is an answer like that:

You need to change the password of your Mysql, the password and port of your ftp, and so on.


Thanks!

 

i think you need to change password ( vps/cpanel password, wordpress admin password, database password, ftp ), turn off ssh.

 

change the password on the VPS to make sure he is unable to re connect via ssh/sftp
type: passwd
In the cmd and you will be prompted to change your password, Make sure your logged in as root also make sure you
type: Users
and see if their is anything other then root logged in, If so remove their user account if its not a wheel users or anything.

Use your text editor and edit the file at
/etc/ssh/sshd_config

Where is says port change it to your desired port and then do

/etc/init.d/ssh restart

If your interested I could help you out more, But I am sure you want to do this yourself unless you wanted to team viewer or something so im able to show you

 

Thanks man that was really helpful. What about the other stuff, like MySQL, etc? Does it have a password too?

 

your able to change your mysqls root password by
mysqladmin -u root -pcurrentpassword password 'newpassword'

 

Thanks. Is there any other password to change?

 

that should be it Unless you have any other software installed that requires its own pass?

 

I think there is not another software.. is there a command to check?

 

Nothing I can think of tbh, Maybe your postfix mail stuff but that would be it, Also you can just google that if you have it installed.

 

Hummm, thanks man! You really helped

 

No Problem

 

Hey @MonsteRNaruto , when I type /etc/ssh/sshd_config I get permission denied, how do I change the port? And what numbers can I choose, and how will it affect my site? Thanks!

 

depends what OS your using, Install nano
centos - yum install nano
ubuntu/debian - apt-get install nano

Then do - nano /etc/ssh/sshd_config

Look for the line that says
# port 22
remove the # and change the port to the desired port and then reboot ssh with - /etc/init.d/ssh restart

 

Thanks I´ll try it. What exactly is Nano?

 

nano is a text editor on the command line.

 

It worked, thanks!

Btw, do you know how to set an automatic backup?
For example, every sunday at midnight.
Thanks!

 

if you like pm me and ill send you my skype will be much faster + That way I can send you a script for backups i coded if needed.
