记一次docker-compose启动elk的问题

直接贴错

ERROR: [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch.
bootstrap check failure [1] of [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
ERROR: Elasticsearch did not exit normally - check the logs at /usr/share/elasticsearch/logs/es-cluster.log

错误描述是本地虚拟内存太少了，需要增加到262144

所以：
vim /etc/sysctl.conf

写入

vm.max_map_count=655360

保存退出

加载一下：

sysctl -p

重启一下：

docker-compose -f docker-elk.yml up -d
