mongodb 简单操作
# 可以通过 kubectl -n klvhcen exec -it POD_NAME /bin/bash 进入容器
# 进入 mongodb 客户端
mongo admin
# 认证
db.auth('root','klvu9chen123')
# mongodb 创建 test 数据库,创建用户和密码
use test
db.createUser(
{
user: "test",
pwd: "test123",
roles: [ { role: "readWrite", db: "test" } ]
}
)
# 备份,会在当前目录下默认创建名为 dump 的备份文件夹
mongodump --host 127.0.0.1 --port 27017 -u test --authenticationDatabase test
# 恢复
mongorestore --host 127.0.0.1 --port 27017 -u test --authenticationDatabase recommend dump
