For simple one server deployments and tests, we have a deploy script available you can run on a fresh CentOS (or Red Hat Enterprise Linux) 7 installation. It will configure all components and will be ready for use after running!
An additional script is available after deployment:
- Use Let's Encrypt for automatic web server certificate management;
- Clean CentOS (or Red Hat Enterprise Linux) 7 installation with all updates installed;
- For Red Hat Enterprise Linux the system should be registered at Red Hat with the subscription manager (not required for CentOS);
- SELinux MUST be enabled (CentOS SELinux);
- Network equipment/VM platform allows access to the very least
tcp/80
,tcp/443
,udp/1194
andtcp/1194
for basic functionality, the deploy script will take care of the host firewall; - Working DNS entry for your VPN server, e.g.
vpn.example.org
.
We test only with the official CentOS
Minimal ISO and the official
Cloud images. For Red Hat Enterprise Linux
we test with the official Red Hat Enterprise Linux ISO, e.g.
rhel-server-7.5-x86_64-dvd.iso
.
If you have a more complicated setup, we recommend to manually walk through the deploy script and follow the steps.
Perform these steps on the host where you want to deploy:
$ curl -L -O https://github.com/eduvpn/documentation/archive/master.tar.gz
$ tar -xzf master.tar.gz
$ cd documentation-master
Run the script (as root):
$ sudo -s
# ./deploy_centos.sh
Specify the hostname you want to use for your VPN server. Both the "Web" and "OpenVPN" DNS names can be identical for simple 1 machine setups.
NOTE: you can NOT use localhost
as a hostname, nor an IP address!
Periodically install updates!
See PROFILE_CONFIG on how to update the VPN server settings.
By default there is a user me
with a generated password for the User Portal
and a user admin
with a generated password for the Admin Portal. Those are
printed at the end of the deploy script.
If you want to update/add users you can use the vpn-user-portal-add-user
and
vpn-admin-portal-add-user
scripts. Provide an existing account to update
the password:
$ sudo vpn-user-portal-add-user
User ID: foo
Setting password for user "foo"
Password:
Password (repeat):
It is easy to enable LDAP authentication. This is documented separately. See LDAP.
It is easy to enable RADIUS authentication. This is documented separately. See RADIUS.
It is easy to enable SAML authentication for identity federations, this is documented separately. See SAML.
For connecting to the VPN service by default only certificates are used, no additional user name/password authentication. It is possible to enable 2FA to require an additional TOTP or YubiKey.
If you want to restrict the use of the VPN a bit more than on whether someone has an account or not, e.g. to limit certain profiles to certain (groups of) users, see ACL.
Run the script (as root):
$ sudo -s
# ./lets_encrypt_centos.sh
Make sure you use the exact same DNS name you used when running
deploy_centos.sh
!
After completing the script, the certificate will be installed and the system will automatically replace the certificate before it expires.
If you also want to allow clients to connect with the VPN over tcp/443
, see
Port Sharing.
See BRANDING.
