What you will want
To efficiently set up Pritunl on AlmaLinux, you will want a working/up to date occasion of the OS and a consumer with sudo privileges. You will additionally want a website title that factors to the internet hosting server (so customers can entry the VPN from outdoors your community).
configure the firewall
The very first thing we’ll do is configure the AlmaLinux firewall. Let’s begin by permitting each HTTP and HTTPS site visitors in with the instructions:
sudo firewall-cmd --permanent --add-service=http sudo firewall-cmd --permanent --add-service=https
Then, we’ll reload the firewall with:
sudo firewall-cmd --reload
set up MongoDB
Subsequent, we’ll set up the MongoDB database. Create a brand new repo file with:
sudo nano /and so on/yum.repos.d/mongodb-org-4.4.repo
Paste the next into the brand new file:
[mongodb-org-4.4] title=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc
Word: There is a newer model of MongoDB (model 5), however I’ve but to efficiently get it to put in on AlmaLinux. Due to that, I am going with model 4.4.
Save and shut the file.
Set up MongoDB with:
sudo dnf set up mongodb-org -y
Begin and allow MongoDB with:
sudo systemctl allow --now mongod
set up Pritunl Server
Subsequent, we’ll set up Pritunl. Create the repo file with:
sudo nano /and so on/yum.repos.d/pritunl.repo
In that file, paste the next:
[pritunl] title=Pritunl Repository baseurl=https://repo.pritunl.com/secure/yum/centos/8/ gpgcheck=1 enabled=1
Save and shut the file.
Set up the EPEL repository with:
sudo dnf set up epel-release -y
Import the Pritunl GPG keys with:
gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 7568D9BB55FF9E5287D586017AE645C0CF8E292A gpg --armor --export 7568D9BB55FF9E5287D586017AE645C0CF8E292A > key.tmp; sudo rpm --import key.tmp; rm -f key.tmp
Set up Pritunl with the command:
sudo dnf set up pritunl -y
When the set up completes, begin and allow the service with:
sudo systemctl allow pritunl --now
enhance the Open File Restrict
To forestall connection points to the Pritunl server when it is underneath the next load, we have to enhance the open file restrict. To do that, challenge the next instructions:
sudo sh -c 'echo "* arduous nofile 64000" >> /and so on/safety/limits.conf' sudo sh -c 'echo "* tender nofile 64000" >> /and so on/safety/limits.conf' sudo sh -c 'echo "root arduous nofile 64000" >> /and so on/safety/limits.conf' sudo sh -c 'echo "root tender nofile 64000" >> /and so on/safety/limits.conf'
entry the Pritunl internet UI
Give the service a second to begin after which level an internet browser to https://SERVER (the place SERVER is both the IP handle or area of the internet hosting server). You have to be greeted by the Pritunl database setup window (Determine A).
To proceed, you need to generate a setup key with the command (run on the internet hosting server):
sudo pritunl setup-key
This may generate a random string of characters that you just copy and paste into the Setup Key textual content space of the Pritunl database setup window. After pasting the important thing, click on Save and anticipate the database to be upgraded. You’ll then be introduced with the Pritunl login window. Earlier than you log in, you need to retrieve the default login credentials with the command:
sudo pritunl default-password
The above command will print out each the username and password so that you can use to log into the Pritunl internet UI. Be sure that to save lots of these credentials. As soon as you’ve got efficiently logged in, you will be prompted to alter the admin consumer’s password and full the preliminary setup (Determine B).
And there you go. You now have the Pritunl VPN server up and working on AlmaLinux 8.5. At this level, you possibly can configure the server to fulfill the wants of your enterprise and customers.
