Computer !
Previously we discussed about how to install Apache and PHP from source. Installing LAMP stack from source will give you full control to configure different parameters.Installing LAMP stack using yum is very easy and takes only minutes. This is a good option for beginners who don’t feel comfortable installing from source. Also, Installing LAMP stack using yum is a good choice, if you want to keep things simple and just use the default configuration.
1. Install Apache using Yum
# rpm -qa | grep httpd
[Note: If the above command did not return anything,
install apache as shown below]
# yum install httpdVerify that Apache got installed successfully# rpm -qa | grep -i http httpd-tools-2.2.9-1.fc9.i386 httpd-2.2.9-1.fc9.i386Enable httpd service to start automatically during system startup using chkconfig. Start the Apache as shown below.
# chkconfig httpd on # service httpd start Starting httpd: [ OK ]
2. Upgrade Apache using Yum
If you’ve selected web server package during Linux installation, Apache is already installed on your Linux. In which case, you can upgrade Apache to the latest version as shown below.Check whether Apache is already installed.
# 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]Check whether latest version of Apache is available for installation using 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]Upgrade Apache to latest version using yum.# yum update httpdOutput of the yum update httpd command:

# chkconfig mysqld onStart MySQL service.
# service mysqld startThe first time when you start mysqld, it will give additional information message indicating to perform post-install configuration as shown below.
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_installationwhich 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! The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com Starting MySQL: [ OK ]
4. Perform MySQL post-installation activities
After the mysql installation, you can login to mysql root account without providing any password as shown below.# 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>To fix this problem, you need to assign a password to mysql root account as shown below. Execute mysql_secure_installation script, which performs the following activities:
- Assign the root password
- Remove the anonymous user
- Disallow root login from remote machines
- Remove the default sample test database
# /usr/bin/mysql_secure_installationOutput of mysql_secure_installation script:
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!Verify the MySQL post-install activities:# mysql -u root ERROR 1045 (28000):Access denied for user 'root'@'localhost'(using password:NO) [Note: root access without password is denied] # mysql -u root -p Enter password: Welcome to the MySQL monitor.
