虚拟机docker elasticsearch启动失败

使用官方的quickstart Start a single-node cluster in Docker | Elastic Docs 发现elasticsearch启动不起来

使用docker logs es01 查看日志

关键错误信息：bootstrap check failure [1] of [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144];

简单来说max_count 太小了

解决方法：

修改vim /etc/sysctl.conf

插入vm.max_map_count=262144

生效： sysctl -p
 

再重新启动es01 

docker container start es01

成功！
