修改redis.conf 中的内容如下：

pidfile  /var/run/redis_7000.pid          //pidfile文件对应7000,7001,7002,7003
port  7000                                //端口7000,7002,7003
cluster-enabled  yes                      //开启集群  把注释#去掉
cluster-config-file  nodes_7000.conf      //集群的配置  配置文件首次启动自动生成 7000,7001,7002
cluster-node-timeout  5000                //请求超时  设置5秒够了
bind 192.168.6.24 127.0.0.1               //绑定id (注意本机id一定是第一个)
appendonly  yes                           //aof日志开启  有需要就开启，它会每次写操作都记录一条日志
logfile "/var/log/redis/7000.log"

7001  7002  7003  7004  7005  操作与7000相同

GPG signature verification failed for '/usr/local/rvm/archives/rvm-1.29.3.tgz' - 'https://github.com/rvm/rvm/releases/download/1.29.3/1.29.3.tar.gz.asc'! Try to install GPG v2 and then fetch the public key:

the key can be compared with:

Creating group 'rvm'

Installing RVM to /usr/local/rvm/
            source /etc/profile
Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
