Install Webpy 0.1 via darwinports.
Adapted from macdevlog
sudo port selfupdate
sudo port install python24
sudo port install postgresql81
curl -O "http://webpy.org/web.py"
curl -O "http://jaist.dl.sourceforge.net/sourceforge/cheetahtemplate/Cheetah-1.0.tar.gz" gunzip Cheetah-1.0.tar.gz tar -xvf Cheetah-1.0.tar rm Cheetah-1.0.tar cd Cheetah-1.0 sudo python ./setup.py install cd .. sudo rm -Rf Cheetah-1.0
The version in darwinports is the older 1.x code branch. Since we’ve installed Postgres in to a non-standard location, we have to nugde the setup.cfg file just a little bit.
curl -O "http://initd.org/pub/software/psycopg/psycopg2-latest.tar.gz" tar -xzvf psycopg2-latest.tar.gz rm psycopg2-latest.tar.gz cd psycopg2-2.0.4 echo library_dirs=/opt/local/lib/postgresql81 >> setup.cfg echo include_dirs=/opt/local/include/postgresql81 >> setup.cfg sudo python setup.py install cd .. sudo rm -Rf psycopg2-2.0.4
Download pgadmin (optional)
To create a postgre user and group, we are going to use netinfo. According to reports, Mas OS X 10.5 Leopard will be stripped of netinfo. These commands are likely to be Tiger only.
First, find an unused userID and groupID. typically anything in the 200s or 300s will be unused on most Mac OS X non-server systems. Let’s assumes uid 206 and gid 207 If you need to check which uid and gid are in use, the following netinfo commands can be used:
nireport / /users name uid nireport / /groups name gid
Make the users and groups:
sudo niutil -create / /groups/postgres sudo niutil -createprop / /groups/postgres gid 207 sudo niutil -create / /users/postgres sudo niutil -createprop / /users/postgres uid 206 sudo niutil -createprop / /users/postgres gid 207 sudo niutil -destroyprop / /users/postgres passwd changeme
Now, we need a data store. We can use the Users/Shared directory for this.
mkdir /Users/Shared/PostgreSQL sudo mkdir /Users/Shared/PostgreSQL/data sudo chown postgres /Users/Shared/PostgreSQL/data sudo chgrp postgres /Users/Shared/PostgreSQL/data sudo -u postgres /opt/local/lib/postgresql81/bin/initdb -D /Users/Shared/PostgreSQL/data
The initdb comnmand will take a moment, but output the status and notify you of success at the end.
Starting and stopping postgreSQL
The -b will launch the process in the backgroud.
sudo -b -u postgres /opt/local/lib/postgresql81/bin/postmaster -D /Users/Shared/PostgreSQL/data >/Users/Shared/PostgreSQL/logfile 2>&1
This is how you stop a postgres process.
sudo -u postgres /opt/local/lib/postgresql81/bin/pg_ctl -D /Users/Shared/PostgreSQL/data stop
Create a user and a test db. Our user is called webpy and the name of the database is webpydb.
sudo -u postgres /opt/local/lib/postgresql81/bin/createuser --no-superuser --createdb --no-createrole webpy sudo -u postgres /opt/local/lib/postgresql81/bin/createdb --username=webpy webpydb sudo -u postgres /opt/local/lib/postgresql81/bin/createlang plpgsql webpydb sudo -u postgres /opt/local/lib/postgresql81/bin/psql -c "create group webpydb" sudo -u postgres /opt/local/lib/postgresql81/bin/psql -c "alter group webpydb add user webpy"
If these commands are successful, you should see ‘CREATE ROLE’, ‘CREATE DATABASE’, ‘CREATE LANGUAGE’, ‘CREATE ROLE’, and ‘ALTER ROLE’ printed out for the respective commands.
During most of these steps, we shell into root. Be careful or your could break something.
cd /Users/Shared/PostgreSQL/ sudo sh cd data
Backup the pg_hba.conf file and then remove the 1 line that starts with local and the 2 lines that start with host. These default values are way to insecure.
mv pg_hba.conf pg_hba.conf.bak sed -e '/^local/ d' -e '/^host / d' pg_hba.conf.bak > pg_hba.conf
Make the conf file secure. These are based off of the Apple recommended settings. Feel free to customize if you know what you are doing.
echo 'local all all md5' >> pg_hba.conf echo 'host all postgres 127.0.0.1/32 md5' >> pg_hba.conf echo 'host samegroup all 127.0.0.1/32 md5' >> pg_hba.conf echo 'host all postgres ::1/128 md5' >> pg_hba.conf echo 'host samegroup all ::1/128 md5' >> pg_hba.conf chown postgres pg_hba.conf exit
Done with root. All that remains is to assign passwords to the username. Have you have ever had that dream where you go to school or work but have forgotten your pants?. Skipping this step is kind of like that part of the dream where the cute girl is laughing and pointing at your open port. Make sure the command outputs ‘ALTER ROLE’ to verify success.
sudo -u postgres /opt/local/lib/postgresql81/bin/psql -c "alter user postgres with password 'changeme1'" sudo -u postgres /opt/local/lib/postgresql81/bin/psql -c "alter user webpy with password 'changeme2'" Time to reload and restart pgSQL sudo -u postgres /opt/local/lib/postgresql81/bin/pg_ctl -D /Users/Shared/PostgreSQL/data reload
You can follow the webpy tutorial as long as you make the following change:
web.db_parameters = dict(dbn='postgres', user='webpy', pw='changeme2', db='webpydb')
Also, you can use the following command to send database SELECT and INSERT querys:
/opt/local/lib/postgresql81/bin/psql webpy webpy SOME_QUERY
These folowing two items are for production deployment. You won’t not need them if you are just taking a quick look at web.py. If you do want to play with around with a simple server setup, the following commands will get you started.
sudo port install lighttpd curl -O http://www.saddi.com/software/flup/dist/flup-r2028.tar.gz
