用法
cluster-config-file nodes-6379.conf
注意事项：
默认文件名nodes.conf，所以不修改的话，所有节点都会是这个。
每一个cluster node都要设置自己的文件名，不然第一个创建的nodes.conf会占位。

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /usr/local/var/run/redis.pid when daemonized.
# When Redis is supervised by upstart or systemd, this parameter has no impact.
daemonize no
