windows下面mongodb数据库备份和恢复
我可以讲数据备份到c:\data\dump目录下面,首先创建这个路径。然后进入到mongodb的bin目录下面
我的是:
C:\Program Files\mongodb\bin
备份脚本是:
//备份 mongodump -h 127.0.0.1:27017 -d test -o c:\data\dump
恢复脚本是:
//恢复 mongorestore -h 127.0.0.1:27017 -d test --directoryperdb c:\data\dump\test
解释一下用到的命令
原始解释:
-v [ --verbose ] be more verbose (include multiple times for more verbosity e.g. -vvvvv) --version print the program's version and exit -h [ --host ] arg mongo host to connect to ( <set name>/s1,s2 for sets) --port arg server port. Can also use --host hostname:port --ipv6 enable IPv6 support (disabled by default) -u [ --username ] arg username -p [ --password ] arg password --authenticationDatabase arg user source (defaults to dbname) --authenticationMechanism arg (=MONGODB-CR) authentication mechanism --dbpath arg directly access mongod database files in the given path, instead of connecting to a mongod server - needs to lock the data directory, so cannot be used if a mongod is currently accessing the same path --directoryperdb each db is in a separate directly (relevant only if dbpath specified) --journal enable journaling (relevant only if dbpath specified) -d [ --db ] arg database to use -c [ --collection ] arg collection to use (some commands) --objcheck validate object before inserting (default) --noobjcheck don't validate object before inserting --filter arg filter to apply before inserting --drop drop each collection before import --oplogReplay replay oplog for point-in-time restore --oplogLimit arg include oplog entries before the provided Timestamp (seconds[:ordinal]) during the oplog replay; the ordinal value is optional --keepIndexVersion don't upgrade indexes to newest version --noOptionsRestore don't restore collection options --noIndexRestore don't restore indexes --w arg (=0) minimum number of replicas per write
linux下面mongodb数据库备份和恢复
linux下面我们可以创建一个自动备份脚本,可以设置定时任务,也可以手动备份。我是手动备份的。
首先创建一个sh命令,我是放在home下面的。
vim /home/mongoBeiFen.sh
输入如下内容:
#!/bin/bash shijie=`date +%Y%m%d%H` backmongodbFile=mongodb$shijie.tar.gz cd /home/mongoDbback/ /usr/local/mongo/bin/mongodump -h 127.0.0.1 --port 27017 -u mongo -p 123456 -d my_mongodb -o my_mongodb_dump/ tar czf $backmongodbFile my_mongodb_dump/ rm my_mongodb_dump -rf
解释:
存放备份的文件夹是/home/mongoDbback/
-u是数据库名用户名 -p是密码 -d是数据库名 具体和window差不多,大家可以看下上面windows的解释。
备份的时候只要运行一下
./mongoBeiFen.sh
就可以了。
数据库恢复:
/usr/local/mongo/bin/mongorestore -d my_mongodb my_mongodb_dump/my_mongodb/*
指向每个文件
复制代码 代码如下:
/usr/local/mongo/bin/mongorestore -h 127.0.0.1 --port 27017 -- drop --directoryperdb my_mongodb_dump/my_mongodb
指向一个目录
有问题的话可以尝试window的写法:
复制代码 代码如下:
/usr/local/mongo/bin/mongorestore -h 127.0.0.1:27017 -d test --drop --directoryperdb my_mongodb_dump/my_mongodb
