Error installing redis: redis requires Ruby Version > = 2.3.0

Error installing redis: redis requires Ruby Version & gt= 2.3.0.

Error installing redis: redis requires Ruby Version & gt= 2.3.0.

Recently, the following error was reported when installing redis cluster:
the version of ruby in centos7 Yum library supports 2.0.0, but gem needs at least 2.3.0 to install redis, and uses RVM to update ruby

Follow the steps below

1. Install curl

yum -y install curl

2. Install RVM

curl - L get.rvm.io | bash - s stable
this is an installation failure error

this situation mostly occurs in self signed certificates. The error report means that the issuing certificate authority is not authenticated and cannot be identified.

3. Modify hosts

VI/etc/hosts
add the following
199.232.28.133 raw.githubusercontent.com

4. Execute curl command and download RVM

curl - L get.rvm.io | bash - s stable

Load shell configuration
source/usr/local/RVM/scripts/RVM

5. Check the known Ruby versions in RVM library

rvm list known

6. Install the ruby version

rvm install 2.6.3

7. Use Ruby Version

rvm use 2.6.3

8. Set the default version

ruby --version

9. Uninstall the old version

rvm remove 2.0.0

10. Install the interface version of redis and ruby

gem install redis

This is the perfect solution~
