I found that there are some installation problems?

  Temporarily unresolved.

It may be due not take effect library, reboot reboot, perform the discovery again

[root@hadoop02 redis-client]# ls
redis-4.1.3.gem
[root@hadoop02 redis-client]# gem install redis-4.1.3.gem 
ERROR:  Error installing redis-4.1.3.gem:
	redis requires Ruby version >= 2.3.0.

It is a different version, so to upgrade ruby ​​version. This is relatively easy to handle, go to the official website to download the latest version, and use the source code installation.

wget https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.5.tar.gz

#解压后
[root@hadoop02 ruby-2.6.5]# ./configure --prefix=/usr/local/ruby
