vm.max_map_count 报错
grep vm.max_map_count /etc/sysctl.conf # 如果找不到，则在该文件中添加 vm.max_map_count=262144 然后执行 sysctl -p # 临时改变轻执行 sysctl -w vm.max_map_count=262144 -
不能以root权限运行问题
请检查Elasticsearch挂载的目录是否是root用户创建的 -
Kibana链接问题
直接通过docker-compose server name链接即可 -
kibana无法登陆问题
# 添加以下选项： XPACK_SECURITY_ENABLED: "false"
