Vuze requiring root access to update4/17/2024 Next I’m going to create the ssh-keys and make it possible to login without using a password. Now it doesn’t allow me to log in as a root user anymore. Next, I’ll test, what happens if I try to login as root via ssh password: Now, I have to restart the daemon to apply the changes Here, I have to uncomment the following line and change the value to ”no”: Ssh it works, now we can safely prevent login of the root user Next we try to login with this new user via ssh A good password is at least 12 digits long and contains at least one of lower case letters, upper case letters, numbers and special characters.Īnd finally, add the user into sudoers group In centos, it’s possible to do by following the steps taken from this guide:įor the new user, I need to initialize a password. Okay, now the firewall is set, it is time to create a new user and block remote access to root for security reasons. If that –permanent-annotation would have been left out, the rould had dropped during the next boot. Next part is where I set the port 22 to be permanently allowed in public-zone. What I did was first setting the firewalld to run and confirming it (state says ”running”). Redirecting to /bin/systemctl start ~]# firewall-cmd ~]# sudo firewall-cmd -zone=public -permanent ~]# sudo firewall-cmd -list-all Luckily there’s good tutorial about configuring it and I’ll be referencing to it during this setup ~]# sudo service firewalld start Apparently Firewalld is a new replacement of the iptables on centos-side, so I need to study it a little bit. Next thing to do, would be setting up a firewall to prevent any unwanted access to the server. Ssh very first thing is to change your root password, because emailed passwords will bring a serious security risk, even though I’m going to disable the use of root user. So first, I’ll establish an ssh connection to the server Now it’s time to login and follow these steps Now the VPS is created and I have my root user’s password sent to my email. I change the hostname to be wordpress-centos-vps and hit ”create” When that is accomplished, the following management page opens:įirst I click the green ”create” button and from the dropdown-menu, I pick ”droplets” which is a term on DigitalOcean’s service catalogue for these VPS packages. Since the cheapest server pack is $5/month, I can run that server for 10 months without need to pay.įirst thing of course is to register to the service and create an account. I choose DigitalOcean, because it’s pretty cheap, but also I happen to have a github education pack, which provides me $50 for free. If there’s a need for more complex tools, like load balancing multiple servers and hosting server containers, there’s Amazon’s AWS, Google Cloud Platform and Microsoft Azure to mention the biggest ones. The recommended ones, that are cheapest, are DigitalOcean, Linode and Tilaa (limited in the netherlands). Renting a vpsįirst I need to choose a VPS provider. On the security key generation part, I’ll be using the same laptop I used in my post Xubuntu boot stick creation. – install CA-authorized certificates to enable HTTPS – initialize domain name to our WP service – check the security logs for bot traffic This time I’m going to do the following steps: Tero Karvinen’s Linux course is stepping into a world of servers and I got some homeworks revolving around the topic.
