安装必要软件和创建文件夹

sudo yum install zlib-devel -y
sudo yum install openssl-devel -y
sudo mkdir -pv /opt/redis_data
sudo mkdir -pv /usr/local/redis/cluster

安装redis-4.0.14

cd /opt/redis-4.0.14
sudo make  -j 4 && sudo make  install -j 4

安装ruby

tar -xvf ruby-2.3.1.tar.gz
cd /opt/ruby-2.3.1.tar.gz
sudo ./configure -prefix=/usr/local/ruby
sudo make -j 4 && sudo  make -j 4 install
sudo vim /etc/profile.d/ruby.sh
//ruby.sh文件内容如下
RUBY_HOME='/usr/local/ruby'
PATH=$PATH:$RUBY_HOME/bin
export RUBY_HOME PATH
#############################
//上述保存完后执行
source /etc/profile.d/ruby.sh
