我曾尝试单独安装
mongo
2.6,但导致其他软件包被标记为删除。最终我只卸载了旧软件包并重新安装新版本,并在此提供过程以供参考。
以下步骤中的一些并没有起作用,但我将它们和它们的结果包含在内,作为尝试的记录。我之前已经对所有数据库进行了
mongodump
备份。
最终结果是,除了
admin
数据库恢复外,目前似乎一切都“正常”。
01. 关闭
mongod
。
mongo
use admin
db.shutdownServer()
来自: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/
02. 使用以下方法删除了 mongodb-10gen
的“固定软件包”状态:
echo "mongodb-10gen install" | sudo dpkg --set-selections
来自:https://help.ubuntu.com/community/PinningHowto
03. 然后我尝试使用以下命令安装最新的mongo
:
sudo apt-get install -y mongodb-org-shell
来自:http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
04. Shell 版本似乎已更新:
mongo --version
MongoDB shell version: 2.6.6
05. 但是我无法连接到 mongo
:
mongo
connecting to: test
2015-01-04T00:08:50.482+1000 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-01-04T00:08:50.483+1000 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed
或者mongod
:
mongod
The program 'mongod' is currently not installed. You can install it by typing:
sudo apt-get install mongodb-server
06. 我运行了下面的命令来查看apt-get安装/卸载的历史记录:
less /var/log/apt/history.log
并获得:
Start-Date: 2015-01-04 00:02:08
Commandline: apt-get install -y mongodb-org-shell
Install: mongodb-org-shell:amd64 (2.6.6)
Remove: mongodb-10gen:amd64 (2.4.9)
End-Date: 2015-01-04 00:02:21
07. 我运行了:
dpkg --get-selections
并看到:
mongodb-10gen deinstall
我认为“deinstall”意味着标记为删除。
08. 我决定使用以下命令删除所有的“mongodb-10gen”软件包:
sudo apt-get purge mongodb-10gen

dpkg: warning: while removing mongodb-10gen, directory '/var/lib/mongodb' not empty so not removed
来自:https://askubuntu.com/a/147177
09. 我备份了无法删除的目录,即/var/lib/mongodb
:
sudo cp -avr /var/lib/mongodb/ /home/
10. 然后将其移除。
cd /var/lib/
sudo rm -rf mongodb/
11. 我搜索了一下是否还有任何mongodb-10gen
包留存:
dpkg --get-selections | grep "mongodb-10gen"
返回了空值。
12. 我通过Synaptic软件包管理器安装了版本为2.6.6的mongodb-org
。
13. 我检查了所有的mongodb软件包都是相同的版本:
mongodump --version
mongorestore --version
mongo --version
mongod --version
mongos --version
14. 然后我使用每个数据库转储进行了 mongorestore
操作,例如:
mongorestore --db dname_01 /path/to/dump/dbname_01/
mongorestore --db dname_02 /path/to/dump/dbname_02/
这似乎在所有数据库上都起作用,但在admin
数据库上失败了:
assertion: 17415 Cannot restore users with schema version 1 to a system with server version 2.5.4 or greater
而且users
数据库发生了一些异常,例如:
Restoring to users.pending_registrations without dropping. Restored data will be inserted without raising errors
Restoring to users.roles without dropping. Restored data will be inserted without raising errors
Restoring to users.users without dropping. Restored data will be inserted without raising errors
15. 我运行了 db.upgradeCheckAllDBs()
:
mongo
use admin
db.upgradeCheckAllDBs()
Checking database local
Checking collection local.startup_log
Checking collection local.system.indexes
Checking database dname_01
...
Checking database admin
Everything is ready for the upgrade!
