Installing eZ Publish on a Linux/UNIX based system

The requirements for doing a normal installation must be met! Read the "Requirements for doing a normal installation" section first. Proceed only if you have access to a Linux/UNIX based system with Apache, PHP, MySQL or PostgreSQL already installed and running. As mentioned earlier, the database server may run on a different computer than the web server. This section will guide you through the following steps:

Setting up a database (MySQL or PostgreSQL)
Downloading eZ Publish
Unpacking eZ Publish
Initiating the setup wizard

Setting up a database

A database must be created before running the setup wizard. The following text explains how to set up a database using either MySQL or PostgreSQL.

MySQL

Log in as the root user (or any other MySQL user that has the CREATE, CREATE USER and GRANT OPTION privileges):
```
$ mysql --host=<mysql_host> --port=<port> -u <mysql_user> -p<mysql_password>
```
Note that if MySQL is installed on the same server, the "--host" parameter can be omitted. If the "--port" parameter is omitted, the default port for MySQL traffic will be used (port 3306).
The MySQL client should display a "mysql>" prompt.

Create a new database:

mysql> CREATE DATABASE <database> CHARACTER SET utf8;

Grant access permissions:
```
mysql> GRANT ALL ON <database>.* TO <user>@<ezp_host> IDENTIFIED BY '<password>';
```
Note that if the specified user account does not exist, it will be created.

<mysql_host>	The hostname of the MySQL database server.
<port>	The port number that will be used to connect to the MySQL database server.
<mysql_user>	The MySQL user (if no user is set up, use "root").
<mysql_password>	The password that belongs to the <mysql_user>.
<database>	The name of the database, for example "my_new_database".
<user>	The username that will be used to access the database.
<ezp_host>	The hostname of the server on which eZ Publish will be running. (may be 'localhost' if MySQL is installed on the same server).
<password>	The password you wish to set in order to limit access to the database.

PostgreSQL

Log in as the postgres user (or any other PostgreSQL user that has sufficient privileges to create roles and databases):
```
$ psql -h <psql_host> -p <port> -U <psql_user> -W
```
Note that if PostgreSQL is installed on the same server, the "-h" parameter can be omitted. If the "-p" parameter is omitted, the default port for PostgreSQL traffic will be used (in most cases, port 5432).
The PostgreSQL client will ask you to specify the password that belongs to the <psql_user>. If the password is correct, the client should display a "<psql_user>=#" prompt.

Create a new database:

postgres=# CREATE DATABASE <database> ENCODING='utf8';

Create a new user:

postgres=# CREATE USER <user> PASSWORD '<password>';

Grant access permissions:

postgres=# GRANT ALL PRIVILEGES ON DATABASE <database> TO <user>;

Import the "pgcrypto" module into the new database:

postgres=# \c <database>
<database>=# \i '<path_to_pgcrypto>'

<psql_host>	The hostname of the PostgreSQL database server.
<port>	The port number that will be used to connect to the PostgreSQL database server.
<psql_user>	The PostgreSQL user (if no user is set up, use "postgresql").
<database>	The name of the database, for example "my_new_database".
<user>	The username that will be used to access the database.
<password>	The password you wish to set in order to limit access to the database.
<path_to_pgcrypto>	The path to the "pgcrypto.sql" file, for example "/usr/share/pgsql/contrib/pgcrypto.sql".

Note for version 9.1 of PostgreSQL users: The following changes might be necessary for these users:

postgres=# \c <database>
<database>=# CREATE EXTENSION pgcrypto;

Downloading eZ Publish

The latest community version of eZ Publish can be downloaded from http://share.ez.no/download-develop/downloads.

Unpacking eZ Publish

Use your favorite tool to unpack the downloaded eZ Publish distribution to a web-served directory (a directory that is reachable using a web browser). The following example shows how to do this using the tar utility (to unpack a tar.gz file, assuming that the "tar" and the "gzip" utilities are installed on the system):

$ tar zxvf ezpublish-<version_number>-gpl.tar.gz -C <web_served_directory>

<version_number>	The version number of eZ Publish that was downloaded.
<web_served_directory>	Full path to a directory that is served by the web server. This can be the path to the document root of the web server, or a personal web-directory (usually called "public_html" or "www", and located inside a user's home directory).

The extraction utility will unpack eZ Publish into a sub-directory called "ezpublish-<version_number>". Feel free to rename this directory to something more meaningful, for example "my_site".

Initiating the setup wizard

The setup wizard can be started using a web browser immediately after the previous steps (described in this section) are completed. It will be automatically run the first time someone tries to access/browse the index.php file located in the eZ Publish directory. Let's assume that we are using a server with the host name "www.example.com" and that after unpacking, the eZ Publish directory was renamed to "my_site".

Document root example

If eZ Publish was unpacked into a directory called "my_site" under the document root, the setup wizard can be initiated by browsing the following URL: http://www.example.com/my_site/index.php.

Home directory example

If eZ Publish was unpacked to a web-served directory located inside the home directory of a user with the user name "peter", (usually called "public_html", "www", "http", "html" or "web"), the setup wizard can be initiated by browsing the following URL: http://www.example.com/~peter/my_site/index.php.

Refer to the "The setup wizard" section for a detailed description of the web based setup wizard.
