步骤

有时需要进行数据的备份和恢复, 涉及到大量的小文件拷贝, 速度很慢,找了一个速度相对较快的命令来操作, 记录下

1
cd source/; tar cf - . | (cd target/; tar xvf -)

解决

问题原因是 kibana_system 的用户名密码不正确

修改密码方式

进入 elasticsearch docker 容器内部, 执行

1
2
curl -X POST --cacert config/certs/ca/ca.crt -u "elastic:${ES_PASS}" -H "Content-Type: application/json" 
http://es01:9200/_security/user/kibana_system/_password -d "{\"password\":\"${KIBANA_PASS}\"}"

修改密码
