docker环境安装mongoDB实现平滑迁移实战

docker环境安装mongoDB实现平滑迁移实战

  • 一、备份原始数据（从别的服务器备份到当前服务器）
  • 二、数据迁移
  • 三、迁移过程日志打印
  • 四、验证迁移数据准确性

一、备份原始数据（从别的服务器备份到当前服务器）

使用mongodump工具对原始mongoDB进行全量备份，在备份期间，确保没有新的数据写入，否则这部分数据迁移不到。


docker exec -it 12b9d0ccf6c5 mongodump -h xxx.xxx.xx.xx -u admin -p 123456 -o /data

二、数据迁移

使用mongorestore 工具 将备份的数据文件下载入新的mongDB容器即可：

docker exec -it 502a471acc14 mongorestore -h localhost -u madmin -p 123456 /data

三、迁移过程日志打印

2024-10-16T09:36:03.599+0000    WARNING: On some systems, a password provided directly using --password may be visible to system status programs such as `ps` that may be invoked by other users. Consider omitting the password to provide it via stdin, or using the --config option to specify a configuration file with the password.

到这里数据就迁移到新的容器成功了。

四、验证迁移数据准确性

迁移后验证数据一致性，在两个新旧mongDB环境分别查询集合下的数据量统计，看是否一致，如果一致，则迁移成功。

db.crawler_data.countDocuments();
db.crawler_data_title.countDocuments();
