SAS 9 on Centos may not be officially supported by SAS Institute, but it is supported by the SAS Apps team! At least, we can support the SASjs Server component.
This is a complete guide to setting up SASjs Server on CentOS 7. A SAS runtime is a prerequisite, and a guide to installing that is available here. A guide to installing SASjs Server on Debian / Ubuntu type images is available here
Before you get started, be sure you can obtain the following:
- The IP address of your VPS, with root SSH access, eg:
- A working installation of SAS (or WPS)
- A domain (and access to the DNS panel), eg
- A MongoDB connection string (you can provision one locally or use a free cloud instance)
Let’s get this machine configured! First we log in as root, eg:
# Enter as sudo-enabled user using YOUR new server IP address ssh [email protected]
Next, we create a unix group (
sas) and create the system user account / home directory:
# Create a sas group sudo addgroup sas # Make the user account (eg sasjssrv) and add to sas group sudo adduser sasjssrv -G sas
TLS / SSL
We can generate https certificates using
certbot is packaged as a snap, we’ll also install
# Add EPEL repository sudo yum install epel-release sudo yum upgrade # Install snapd sudo yum install snapd # Enable snap communication socket sudo systemctl enable --now snapd.socket # Create symbolic link sudo ln -s /var/lib/snapd/snap /snap # Now, log out of the session and log back in
Now we are back in the session we can install certbot:
# Remove any previous installation sudo yum remove certbot # Install Certbot. sudo snap install --classic certbot # Make symlink sudo ln -s /snap/bin/certbot /usr/bin/certbot
Before proceeding further, it is necessary to first update your DNS and add an “A record” pointing to your server IP.
Once this is done, we can launch certbot.
# provide domain to prompt WITHOUT https prefix, eg mysas.mycompany.com sudo certbot certonly --standalone # ensure members of the sas group can access the certs # update the paths below according to the actual domain! mkdir /opt/certificates cd /etc/letsencrypt/live/YOURDOMAIN.com cp fullchain.pem /opt/certificates/fullchain.pem cp privkey.pem /opt/certificates/privkey.pem chgrp -R sas /opt/certificates chmod -R 755 /opt/certificates
SASjs Installation & Configuration
The rest of the installation is exactly as described in this article (from “SASjs Installation & Configuration” onwards).
