One-way MySQL DB Syncing for Dummies

To ease my development while on the move, I have local development copies of my websites running on my MacBook Pro. This has always worked pretty well for me, as content for my websites was created, predominantly, by myself, and when new content was created at a single site I could sync that database manually and get an up to date local content set.

With my recent efforts into lifestreaming, this is no longer the case. My content now comes in whenever I post content on any website. I’m a fairly frequent user of the internet services that feed my lifestream (Twitter, Delicious, Flickr, etc), and keeping the content on my local version up to date was turned into a troublesome task, forcing manual, tedious syncing each time I went to work.

Without further explanation, here are the steps I took to make a one line MySQL database syncing command. There may be better ways to do this and if you know them, please comment.

1. Setup a MySQL “dump” user. Mine is cleverly named “dump” and is passwordless, although if you are more security conscious than I am, you can add a password of your choosing. On the server, log into mysql and issue this GRANT statement from a user with the proper permissions.

1	GRANT SELECT, LOCK TABLES ON `dbname_remote`.* TO 'dump'@'localhost';

2. Create a bash alias
~/.bashrc :

1	ALIAS clone_lifestream='ssh -q -t hostname "mysqldump -u dump dbname_remote" \| mysql -u root dbname_local'

Notes: For this example, you need to replace a few things.

dbname = the remote database name
hostname = the remote hostname
dbname_local = the local database name
clone_lifestream = the name of the alias, can be anything.

I always forget this… so this is as much a note for me as anything else.

Especially because I’m basically just lifting this info from here.

sudo gem install mysql -- \
--with-mysql-include=/opt/local/include/mysql5 \
--with-mysql-lib=/opt/local/lib/mysql5 \
--with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config

Despite what the linked website says, it appears that this command works on leopard just fine… no need for any changes.
