Rails Stack on Leopard

October 28th, 2007

Yes, Leopard is that great, but getting a full Rails Stack working again is a lot of work….

(work in progress)

### Ruby / Rails

* Ruby and Rails are bundled with Leopard. Be sure to read about the Apple modifications [What's new in Leopard][6]
* The rails command defaults to sqlite as it’s database. Use:

$ rails -d mysql project_name

### MySQL

* Download 10.4 package from [MySQL][2] and install both the mysql and the startupitem.
* Start/Stop doesn’t work, use [these instructions][4]
* apply the fixes from [AngryFly][5]

### MacPorts

* Download and install [MacPorts 1.5.0-10.5.dmg][3]

### Git

$ sudo port install git-core

### SSH

I have strange errors when the MacPorts version of SSH was being used (no connections, git didn’t pull from remote servers). I “solved” it by renaming it:

$ sudo mv /opt/local/bin/ssh /opt/local/bin/ssh_old

### Subversion

* SVN is bundled in Leopard

### ImageMagic

* following the instructions at [NullStyle][1]

### Postgres

Here’s the [secret sauce to not only make Postgres compile, but also include DTrace support][7] – alas it still doesn’t work for me…

Here’s the munged ./configure line, in case you want to try it:

$ sudo ./configure –sysconfdir=/opt/local/etc/postgresql82 –bindir=/opt/local/lib/postgresql82/bin –libdir=/opt/local/lib/postgresql82 –includedir=/opt/local/include/postgresql82 –datadir=/opt/local/share/postgresql82 –mandir=/opt/local/share/man –without-docdir –with-includes=/opt/local/include –with-libraries=/opt/local/lib –with-openssl –with-bonjour –with-readline –with-zlib –enable-thread-safety –enable-integer-datetimes –enable-dtrace

I have exactly the same error as [here][8]. Hmm, download the Postgres sources?

Finally: A [combination][7] of [instructions][9] got me up and running: (get the DTrace patches and the Postgres Source. Unpack the DTrace patch)

$ sudo port install postgresql82 postgresql82-server

fails as expected

$ cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_databases_postgresql82/work/postgresql-8.2.5
$ cat ~/Desktop/Inbox/postgresql-825-fixosxdtracediff | patch -p1
$ tar xvjf ~/Desktop/Inbox/postgresql-8.2.5.tar.bz2
$ sudo cp -r postgresql-8.2.5/src/ src/
$ sudo ./configure –sysconfdir=/opt/local/etc/postgresql82 –bindir=/opt/local/lib/postgresql82/bin –libdir=/opt/local/lib/postgresql82 –includedir=/opt/local/include/postgresql82 –datadir=/opt/local/share/postgresql82 –mandir=/opt/local/share/man –without-docdir –with-includes=/opt/local/include –with-libraries=/opt/local/lib –with-openssl –without-bonjour –with-readline –with-zlib –enable-thread-safety –enable-integer-datetimes
$ sudo make
$ cd ~
$ sudo port install postgresql82
$ sudo port install postgresql82-server

notice that even though I apply the DTrace patch, I overwrite it in the next line. The ./configure does not enable DTrace. Maybe that part wouldn’t be necessary? Dunno – that was the sequence that compiled and installed for me.

Configure the server:

$ sudo mkdir -p /opt/local/var/db/postgresql82/defaultdb
$ sudo chown postgres:postgres /opt/local/var/db/postgresql82/defaultdb
$ sudo su postgres -c ‘/opt/local/lib/postgresql82/bin/initdb -D /opt/local/var/db/postgresql82/defaultdb’
$ sudo launchctl load -w /Library/LaunchDaemons/org.macports.postgresql82-server.plist

### Ruby Postgres Gem

Home stretch… Based on [Carl Gaywoods instructions][10], here are the commands to install the Postgres Gem with Apples Ruby and the MacPorts Postgres:

$ sudo gem install postgres
$ cd /Library/Ruby/Gems/1.8/gems/postgres-0.7.1/
$ sudo ruby extconf.rb –with-pgsql-include=/opt/local/include/postgresql82 –with-pgsql-lib=/opt/local/lib/postgresql82
$ sudo make
$ sudo make install
$ sudo gem install postgres
