Introduction There are two sections involved in this article: Part 1 covers installation of Apache, MySQL and PHP, while Part 2 deals mainly with installing PostgreSQL. The article assumes that you already installed CentOS52. Assumptions: It’s assumed that you have a good understanding of Linux operating system and its working environment. It’s also assumed that you know how to install and configure Linux CentOS5, if not go ahead and pop over to pdfcoke.com and check out a good HowTo entitled “Install Configure and Upgrade Linux CentOS5 Server v1.1” to get you started. Part 1: Installing Apache, PHP, MySQL These will the basic components for a dynamic, database-driven web site. We use yum to handle of the required packages 1. Install Apache (httpd), PHP, MySQL (server and client), and the component that allows PHP to talk to mysql. yum install httpd* php* mysql* -y Note that: * indicates install all components 2. Configure the service to start automatically /sbin/chkconfig httpd on /sbin/chkconfig --add mysqld /sbin/chkconfig mysqld on /sbin/service httpd start /sbin/service mysqld start 3. IMPORTANT! Set up the mysql database root password. Without a password, ANY user on the box can login to mysql as database root. The mysql root account is a separate password from the machine root account. mysqladmin –u root password 'new-password'

4 Make additional security-related changes to mysql. Mysql –u root –p Mysql> DROP DATABASE test; Mysql> DELETE FROM mysql.user WHERE user =''; Mysql> FLUSH PRIVILEGES;

\\ removes the test dbase \\ removes anonymous across

5. Following the above steps, the document root for Apache is /var/www/hmtl/ 6. Create a test PHP script (test.php) and place in the documents root. A useful test script sample: 7. Create a database and database user for your data. You will use this database and username in your database connection string. The GRANT statement actually creates a new MYSQL user account. Mysql> GREATE DATABASE web_db; Mysql> GRANT ALL PRIVILEGES ON web_db.* TO 'web_user'@'localhost' IDENTIFIED BY 'thepassword'; Part 2: Installing PostgreSQL on Fedora Core (skip MySQL) This will install the PostgreSQL database server and the component required to write PHP scripts that communicate with postgresql. We use yum to handle dependencies and gather all of the required packages. For more information on PostgreSQL, see http://www.postgresql.org 1. Install PostgreSQL and the component that allows PHP to talk to PostgreSQL. # yum -y install postgresql postgresql-server php-pgsql 2. Configure the new service to start automatically on boot # /sbin/chkconfig –-level 345 postgresql on # /sbin/service postgresql start Note: when you start postgresql for the first time, it’ll initialize the database. 3. Start the postgresql interactive shell and create your first user and database. # su - postgres

\\The dash "-" is important!

4. Next, issued the command, "psql template1", to enter the default postgresql database -bash-3.2$ psql template1 Welcome to psql 8.1.11, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit template1=# Note: "template1"is the database that is included by default with PostgreSQL. 5. Check the version of your postgresql: template1=# select version(); version -------------------------------------------------------------------PostgreSQL 8.1.11 on i686-redhat-linux-gnu, compiled by GCC gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-14) (1 row) template1=# \q -bash-3.2$

6. Now create dbase user "webadmin" and make him a superuser: -bash-3.2$ createuser -P webadmin Enter password for new role: Enter it again: Shall the new role be a superuser? (y/n) y CREATE ROLE -bash-3.2$ 7. Next create the database "webdbase" -bash-3.2$ -bash-3.2$ createdb -O webadmin webdbase CREATE DATABASE -bash-3.2$ 8. Now connect into your newly created database: -bash-3.2$ psql webdbase Welcome to psql 8.1.11, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit webdbase=# © April 2007, Kefa Rabah, Global Open Versity, Vancouver Canada

9. Logout of your dbase: webdbase=# \q -bash-3.2$ logout [root@linuxc ~]# 10. Edit the postgres host based access (pg_hba) configuration file: # vi /var/lib/pgsql/data/pg_hba.conf 11. Modify the local line to use "md5" based authentication rather than "ident sameuser". Please review the PostgreSQL documentation before making this change and take the security local

12. Restart the postgresql database service. # /sbin/service postgresql reload

\\restart postgresql

13. Log back into the server # su – postgres 14. Test your connection. \\ or psql webdbase

# psql -U webadmin webdbase

15. Following the above steps, the database location on is /var/lib/pgsql/data. 16. Hooray! – Enjoy LAMP + PostgreSQL Note: You may need to install Webmin from www.webmin.com to ease your server administration pain! 17. Stay tuned! In the coming articles we will show how you use Apache, MySQL/PostgreSQL and PHP, to deploy Moodle LMS, SugarCRM and Drupal.
