Nous avons précédemment expliqué comment installer Apache et PHP à partir des sources. L'installation de la pile LAMP à partir de la source vous donnera un contrôle total pour configurer différents paramètres.
Installation de la pile LAMP utiliser yum est très facile et ne prend que quelques minutes. C'est une bonne option pour les débutants qui ne se sentent pas à l'aise d'installer à partir de la source. De plus, l'installation de la pile LAMP à l'aide de yum est un bon choix, si vous voulez garder les choses simples et utiliser simplement la configuration par défaut.
1. Installer Apache avec Yum
# rpm -qa | grep httpd
[Note: If the above command did not return anything,
install apache as shown below]
# yum install httpd Vérifiez qu'Apache a bien été installé
# rpm -qa | grep -i http httpd-tools-2.2.9-1.fc9.i386 httpd-2.2.9-1.fc9.i386
Activez le service httpd pour qu'il démarre automatiquement lors du démarrage du système à l'aide de chkconfig. Démarrez Apache comme indiqué ci-dessous.
# chkconfig httpd on # service httpd start Starting httpd: [ OK ]
2. Mettre à jour Apache avec Yum
Si vous avez sélectionné le package de serveur Web lors de l'installation de Linux, Apache est déjà installé sur votre Linux. Dans ce cas, vous pouvez mettre à niveau Apache vers la dernière version comme indiqué ci-dessous.
Vérifiez si Apache est déjà installé.
# rpm -qa | grep -i http httpd-tools-2.2.8-3.i386 httpd-2.2.8-3.i386 [Note: This indicates that Apache 2.2.8 version is installed already]
Vérifiez si la dernière version d'Apache est disponible pour l'installation à l'aide de yum.
# yum check-update httpd
Loaded plugins: refresh-packagekit
httpd.i386 2.2.9-1.fc9 updates
[Note: This indicates that the latest Apache version 2.2.9
is available for upgrade] Mettez à niveau Apache vers la dernière version en utilisant yum.
# yum update httpd
Sortie de la yum update httpd commande :

Configurez MySQL pour qu'il démarre automatiquement au démarrage du système.
# chkconfig mysqld on
Démarrez le service MySQL.
# service mysqld start
La première fois que vous démarrez mysqld, il affichera un message d'information supplémentaire indiquant d'effectuer la configuration post-installation comme indiqué ci-dessous.
Initializing MySQL database: Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h dev-db password 'new-password' Alternatively you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is highly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script!

4. Effectuer des activités de post-installation de MySQL
Après l'installation de mysql, vous pouvez vous connecter au compte mysql root sans fournir de mot de passe, comme indiqué ci-dessous.
# mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.0.51a Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql>
Pour résoudre ce problème, vous devez attribuer un mot de passe au compte mysql root comme indiqué ci-dessous. Exécutez le script mysql_secure_installation, qui effectue les activités suivantes :
- Attribuez le mot de passe root
- Supprimer l'utilisateur anonyme
- Interdire la connexion root à partir de machines distantes
- Supprimer l'exemple de base de données de test par défaut
# /usr/bin/mysql_secure_installation
Sortie du script mysql_secure_installation :
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n] Y New password: [Note: Enter the mysql root password here] Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL!
