- 1、vm.max_map_count参数的修改
- 2、su: cannot open session: Permission denied
- 3、启动报错
echo “vm.max_map_count=655360” >> /etc/sysctl.conf
sysctl -p
容器内执行无效，仅能在主机上执行
参考https://stackoverflow.com/questions/41064572/docker-elk-vm-max-map-count
2、su: cannot open session: Permission denied注释文件/etc/pam.d/su中的“session include system-auth”一行即可。
3、启动报错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 file descriptors [4096] for elasticsearch process is too low, increase to at least [65535] ERROR: Elasticsearch did not exit normally - check the logs at /opt/install/elasticsearch-7.13.1/logs/elasticsearch.log
解决方案：
docker run --ulimit nofile=65535:65535
