Installing MySQL gem on Mac OS X Leopard

schwark — Sat, 04 Jul 2009 15:54:51 +0000

Installing the MySQL gem on Leopard was much more painful than I thought. I had the 64-bit version of MySQL already installed. So I had to uninstall MySQL on Leopard, which was a challenge all on its own. Here is what I did (after stopping MySQL, and backing up my databases first, of course):

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
vi /etc/hostconfig # remove the line MYSQLCOM=-YES-

Then I had to install the 32-bit version of MySQL for Mac OS X. After that is installed, I had to use the following to get the gem to compile:

sudo env ARCHFLAGS="-arch i386" gem install mysql -- \
--with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
--with-mysql-include=/usr/local/mysql/include

I knew something like this should and would exist – nice work.. Will try and incorporate into the next Rails thing we do!

Configuring Gmail as SMTP Relay on Elastix

schwark — Sun, 12 Apr 2009 22:33:25 +0000

Elastix uses Postfix, and getting Postfix configured to use Gmail as a SMTP Relay has been incredibly painful to do. This should not be as difficult as it turned out to be, but here is what I had to do to get things working.

Edit the /etc/postfix/main.cf file

nano /etc/postfix/main.cf

Change these lines to your external domain and the name of your elastix server:

################################
#Ingresado por yb-webadmin
mydomain = myrealdomain.gotdns.org
myhostname = elastix.myrealdomain.gotdns.org

Change the following line

#relayhost = [an.ip.add.ress]

relayhost = [smtp.gmail.com]:587

Create a new file /etc/postfix/sasl_passwd and put the following line in it

[smtp.gmail.com]:587       loginname@gmail.com:password

Then run the following command

postmap hash:/etc/postfix/sasl_passwd

Create a directory /etc/postfix/certs. Generate a self-signed certificate as follows

cd /etc/postfix/certs
openssl req -new -x509 -keyout cakey.pem -out cacert.pem -days 365
openssl genrsa -out gm.key 1024
openssl req -new -key gm.key -out gm.csr
openssl ca -cert cacert.pem -keyfile cakey.pem -out ./gm.pem -infiles gm.csr

If you get an error that says something like

Could not open directory ../../CA/newcerts

then do the following before you run the commands above

mkdir -p ../../CA/newcerts
touch ../../CA/index.txt
echo "01" &gt;&gt; ../../CA/serial

and after you are done, you can remove the above directory using

rm -rf ../../CA

Add the following lines to /etc/postfix/main.cf

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =
 
smtp_use_tls = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_note_starttls_offer = yes
tls_random_source = dev:/dev/urandom
smtp_tls_scert_verifydepth = 5
smtp_tls_key_file=/etc/postfix/certs/gm.key
smtp_tls_cert_file=/etc/postfix/certs/gm.pem
smtpd_tls_ask_ccert = yes
smtpd_tls_req_ccert =no
smtp_tls_enforce_peername = no

And finally run

postfix reload

Check your setup by sending a test email

mail myself@myemail.com

And check the logs for anything going wrong

tail -f /var/log/maillog

Social Networking in a box

schwark — Thu, 08 Jan 2009 06:42:55 +0000

I have been looking for a while for a bunch of social networking functionality to use out of the box – it is ridiculous that you have to build all the same basic things over and over again. I think I found exactly what I was looking for – Community Engine can be used as is, but is designed as a plugin as opposed to as an application. Very nice. One of these days, I might actually try it out. Now this is the kind of stuff that makes it harder to go with Django – community is more vibrant on the Rails side.
