MacのMongoDB2.4系を3.2にバージョンアップした

WARNING!!

3.2にあげるには3.0.7以降にしといたほうがいいっぽい

To upgrade an existing MongoDB deployment to 3.2, you must be running 3.0.7 or later.

To upgrade from version 2.6-series, you must upgrade to version 3.0.7 or later before upgrading to 3.2. For the procedure to upgrade from 2.6-series to 3.0-series, see Upgrade MongoDB to 3.0.

3.0にあげるには2.6以降にしといたほうがいいっぽい

To upgrade an existing MongoDB deployment to 3.0, you must be running 2.6. If you’re running a version of MongoDB before 2.6, you must upgrade to 2.6 before upgrading to 3.0. See Upgrade MongoDB to 2.6 for the procedure to upgrade from 2.4 to 2.6. Once upgraded to MongoDB 2.6, you cannot downgrade to any version earlier than MongoDB 2.4.

とりあえず2.4から直接3.2にあげてみて、動いたの確認したからいいかなぁって。

インストールと既存の置き換え

$ tar xvfz mongodb-osx-x86_64-3.2.0.tgz
$ mv mongodb-osx-x86_64-3.2.0/bin/ mongodb32/
$ ln -s mongodb32/ mongodb
$ mongod -version

ストレージエンジンを変更する

$ cd ~/Document
$ mkdir mongodb_bk
$ cd mongodb_bk/
$ cp -r /usr/local/var/mongodb .
$ mongodump --out mongodb_dump
$ rm -rf /usr/local/var/mongodb/*
$ cp /usr/local/etc/mongod.conf /usr/local/etc/mongod.conf.24org
$ vim /usr/local/etc/mongod.conf

mongod.conf
