kafka启动报错failed to map 1073741824 bytes for committing reserved memory

kafka启动./bin/kafka-server-start.sh config/server.properties

报错：failed to map 1073741824 bytes for committing reserved memory

服务器内存不够，无法分配内存.

1. 查看服务器空闲内存多少 free -h

2. 修改kafka启动文件bin/kafka-server-start.sh

将Xmx与Xms改为合适的大小，重启kafka即可
