问题：

在配置redis的时候执行：

lilongjiu@bogon:~/redis/redis-3.0.7/src$ ./redis-trib.rb create --replicas 0 127.0.0.1:9001 127.0.0.1:9002 127.0.0.1:9003

报错：

redis-trib.rb: command not found

解决方法：

1.安装ruby：

lilongjiu@bogon:~/redis/redis-3.0.7/src$ sudo apt-get install ruby

2.安装完查看ruby版本:

lilongjiu@bogon:~/redis/redis-3.0.7/src$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]

3.安装redis的gem

root@bogon:/home/lilongjiu/redis/redis-3.0.7# gem install redis
Fetching: redis-3.2.2.gem (100%)
