kafka啟動時報錯：java.net.UnknownHostException: Name or service not known

今天在用下面的指令啟動kafa的時候報錯了：
# bin/kafka-server-start.sh config/server.properties &
主要是這句：java.net.UnknownHostException: bj1-10-112-179-12: bj1-10-112-179-12: Name or service not known，提示找不到bj1-10-112-179-12這個名字（用hostname指令可以檢視我自己的計算機名就是bj1-10-112-179-12）[2018-04-11 16:27:31,185] ERROR [KafkaServer id=0] Fatal error during KafkaServer startup.

解決方法：
1.開啟/etc/hosts檔案，我的是這樣的
2.改成如下127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 10.112.179.12 VM-10-112-179-12
10.112.179.12 bj1-10-112-179-12 localhost
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
10.112.179.12 VM-10-112-179-12問題解決
