解决 /usr/bin/env: ruby

1、需要准备redis-trib.rb的运行环境

wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz
yum -y install zlib-devel
tar xvf ruby-2.5.1.tar.gz
cd ruby-2.5.1/
./configure -prefix=/usr/local/ruby
make
make install
cd /usr/local/ruby/
cp bin/ruby /usr/local/bin
cp bin/gem /usr/local/bin

2、安装redis-trib依赖

wget http://rubygems.org/downloads/redis-3.3.0.gem
gem install -l redis-3.3.0.gem

3、启动

./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006
