I followed below steps to install Redis on CentOS. But Redis 3.2.x version got downloaded, I want more recent version (i.e 4.0.11 or 5.0.x) to be downloaded.
I need steps how to upgrade the Redis current installation? I used below steps while installation
We can use yum to install EPEL:
sudo yum install epel-release
As soon as we finish installing EPEL, we can use yum once again to install Redis:
sudo yum install redis
After a few minutes this installation will be completed and then you can start the Redis service:
sudo systemctl start redis.service
There is always the chance for Redis to start on boot, all you have to do is enable it through the enable command:
sudo systemctl enable redis
If you want to check Redis`s status you should run the following:
sudo systemctl status redis.service
I have found the Remi repository keeps up with the latest binaries. While you can add them to your repos (see https://rpms.remirepo.net), you can just point yum directly at the rpm file there as well (e.g. yum install -y https://rpms.remirepo.net/enterprise/7/remi/x86_64/redis-5.0.13-1.el7.remi.x86_64.rpm).
Edit: Regarding an upgrade, I assumed you don't have any data at this point, so I would suggest a quick yum uninstall redis before installing the latest. If you really need to upgrade with data and all, you need to just be sure to preserve your persistent data files and replace them before starting the new version.
