Environement setup for Macintosh

Before install and launch Gisgraphy, you must setup java, postgres, and postgis. It is not, properly speaking, the installation of Gisgraphy, and if you already have Postgresql, Postgis and java installed (you needs JVM >= 1.5), you can go directly to the gisgraphy installation guide

Install and configure java / JVM

Since Mac OS 8, Java is installed. You just have to check that you have, at least, java 5.0. if it is note the case, update your Mac OS.

To see if Java is correctly installed, open a shell and type :

java -version

Install postgresql and postgis

If you already have Postgresql AND Postgis installed, you can skip this section

Install the package

To install Postgres and postgis, you need to download some package backport from Unix. Note that you need to download and install the package in the order bellow :

PROJ_Framework
GEOS_Framework
PostgreSQL
PostGIS

To make the installation easier, you can run the following lines in a terminal (it is in the Applications -> Utilities folder), it will download and install Postgres and Postgis automatically :

    mkdir tempinstall
    cd tempinstall
    curl -O http://www.kyngchaos.com/files/software/unixport/PROJ_Framework-4.7.0-2.dmg
    hdiutil attach PROJ_Framework-4.7.0-2.dmg
    sudo installer -pkg /Volumes/*/*.pkg -target "/"
    hdiutil detach /Volumes/PROJ*
    
    curl -O http://www.kyngchaos.com/files/software/unixport/GEOS_Framework-3.2.0-1.dmg
    hdiutil attach GEOS_Framework-3.2.0-1.dmg
    sudo installer -pkg /Volumes/*/*.pkg -target "/"
    hdiutil detach /Volumes/GEOS*
       
      
    curl -O http://www.kyngchaos.com/files/software/unixport/PostgreSQL-8.4.3-1.dmg
    hdiutil attach PostgreSQL-8.4.3-1.dmg
    sudo installer -pkg /Volumes/*/*.pkg -target "/"
    hdiutil detach /Volumes/Postgr*
    
    curl -O http://www.kyngchaos.com/files/software/unixport/PostGIS-1.5.1-1.dmg
    hdiutil attach PostGIS-1.5.1-1.dmg
    sudo installer -pkg /Volumes/*/*.pkg -target "/"
    hdiutil detach /Volumes/PostGIS*

Configure memory

Postgres need a lot of shared memory to run on Macintosh (read more), so you need to increase it. Run the following lines in a terminal (it is in the Applications -> Utilities folder) :

sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216

But this value will be back to their default values when you will startup your Mac. To make these values stick across reboots, add / modify those lines in /etc/sysctl.conf, like this :

kern.sysv.shmall=65536
kern.sysv.shmmax=16777216

Initialize the server

Sometimes The installation is partial ( it is a known issue) and you need to create a directory, give the correct rights and use this folder to store the database :

#Change postgres (mac) user :
sudo passwd postgres
#you need to log in as "postgres" in order to initialise the database (give the password you've just typed
su -l postgres
#create a directory to hold postgres data
mkdir /usr/local/pgsql/data
#create the Database structure
/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data --encoding=UTF8
#launch postgres
/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start

If you got the following message : "Cannot allocate memory", That's probably because there is something wrong with the step "Configure memory".

Configure the postgres user / password

By default the postgres user can connect to postgres with the same password as the Mac one, but we'd like that postgres ask for a password and not use the Mac one

su - postgres

Define the postgres (postgresql) user's password

/usr/local/pgsql/bin/psql -d template1 -c "alter user postgres with password 'YOURPASSWORD'"

if you got the following message : psql command not found, you have to had the path to your PATH : "setenv PATH ${PATH}:/usr/local/pgsql/bin" or "export PATH=$PATH:/usr/local/pgsql/bin"

Now you've changed the password for your postgresql user, we have to tell postgresql to use this password

Update postgres conf

vim /usr/local/pgsql/data/pg_hba.conf

local  all     all                                        password
host   all     all    127.0.0.1         255.255.255.255   password

Restart postgres

You must restart postgresql to take our changes into account :
as postgres (Mac)'s user, type :

/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data reload

Configure Postgis

Here are the command to install a Database and init the Gisgraphy database

# create the database
psql -U postgres  -h YOURIP -c  "CREATE DATABASE gisgraphy ENCODING = 'UTF8';"

#create language
createlang -U postgres -h YOURIP plpgsql gisgraphy 

#create postgis function
psql -U postgres -h YOURIP -d gisgraphy -f /usr/local/pgsql/share/contrib/postgis-1.5/postgis.sql
psql -U postgres -h YOURIP -d gisgraphy -f /usr/local/pgsql/share/contrib/postgis-1.5/spatial_ref_sys.sql

Where YOURIP is the ip adress of your server(127.0.0.1 in most case)

Tips : Install PGAdmin. It will be more user friendly than command line.

In order to know if Postgis is correctly install, open a PostgreSQL connection or PgAdmin and type :

select version (); or SHOW server_version;. It will give you the PostgreSQL version
select postgis_full_version () ; It will give you the Postgis version

Define Environnement settings

Macintosh systems define a maximum number of files that can be open. solr open a large number of files. to avoid message like "Too many open files" you must increase this limit. open a shell and type

sudo ulimit -n6000

that will set the maximum number of open files to 6000.

Sometimes this is not enough. and you have to edit the /etc/security/limits.conf file and add the two following lines :

* hard nofile 20000
* soft nofile 20000

then close and re-open your Mac session to take changes into account.

type ulimit -aH in a shell to check if the value has been set

And now...

Now that you environement is setup, you can go to the Gisgraphy installation guide
