Nacos 0.8.0 cluster environment occurred to find local peer: 127.0.0.1:8848 error

The nacos.log information is as follows:
java.lang.IllegalStateException: unable to find local peer: 127.0.0.1:8848, all peers: [192.168.0.20:8848, 192.168.0.21:8848, 192.168.0.19:8848]

The naming-raft.log information is as follows:
2019-02-15 16:14:45,001 WARN [IS LEADER] no leader is available now!

The host file is as follows:

The cluster.conf file is as follows:
#it is ip

192.168.0.20:8848

当我将每个节点的cluster.conf中对应自身ip的配置换成127.0.0.1，如下：
192.168.0.19机器的cluster.conf配置：
127.0.0.1:8848
192.168.0.20:8848
192.168.0.21:8848

192.168.0.20机器的cluster.conf配置：
192.168.0.19:8848
127.0.0.1:8848
192.168.0.21:8848

192.168.0.21机器的cluster.conf配置：
192.168.0.19:8848
192.168.0.20:8848
127.0.0.1:8848

此时nacos.log无报错信息：

naming-raft.log依然有报错信息：

[polluxxing]

必须保证InetAddress.getLocalHost().getHostAddress()或者hostname -i打印的结果是192.xxx.xxx.xxx而不是127.0.0.1才行。希望文档中某些问题能详细说明，或者优化
