我看网上很多说是 Kafka在启动一段时间后，如果出现服务自动关闭情况，可在启动kafka的时使用守护进程模式启动，即在原启动命令中加 -daemon nohup /home/kafka_2.11-1.0.0/bin/kafka-server-start.sh -daemon /home/kafka_2.11-1.0.0/config/server.properties1 & 可是我加上也不行 ，还有的说是内存不够 ， 以上问题可能会存在吧 ，网上都参考不如自己看下log日志， 到自己定义的kafka 日志输出的目录下找到 server.log 然后查看下

看以上的错 说是Socket server 无法绑定 192.168.252.11:9092 无法获取地址 遇到这个错 可能是server.properties 配置错了 然后找到 server.properties 配置下
listeners=PLAINTEXT://192.168.252.12:9092 或 advertised.listeners=PLAINTEXT://your.host.name:9092
配置完后重新启动就ok 了
