Setup_LAMP_on_CentOS - Jeybla/rathena GitHub Wiki
LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a CentOS server with PHP5 support (mod_php) and MySQL support.
To install MySQL, we do this:
yum install mysql mysql-server
Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
Set passwords for the MySQL root account:
mysql_secure_installation
Then do it like this:
[root@server1 ~]# 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] <-- ENTER
New password: <-- yourrootsqlpassword
Re-enter new password: <-- yourrootsqlpassword
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] <-- ENTER
... 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] <-- ENTER
... 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] <-- ENTER
- 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] <-- ENTER
... 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!
[root@server1 ~]#
Apache2 is available as a CentOS package, therefore we can install it like this:
yum install httpd
Now configure your system to start Apache at boot time...
chkconfig --levels 235 httpd on
... and start Apache:
/etc/init.d/httpd start
Now direct your browser to http://your-ip , and you should see the Apache2 placeholder page.
We can install PHP5 and the Apache PHP5 module as follows:
yum install php
We must restart Apache afterwards:
/etc/init.d/httpd restart
To get MySQL support in PHP, we can install the php-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:
yum search php
Pick the ones you need and install them like this:
yum install php-mysql php-gd php-imap php-ldap php-mbstring php-odbc php-pear php-xml php-xmlrpc
APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It's similar to other PHP opcode cachers, such as eAccelerator and Xcache. It is strongly recommended to have one of these installed to speed up your PHP page.
APC can be installed as follows:
yum install php-pecl-apc
Now restart Apache2:
/etc/init.d/httpd restart
phpMyAdmin is a web interface through which you can manage your MySQL databases.
First we enable the RPMforge repository on our CentOS system as phpMyAdmin is not available in the official CentOS 6.3 repositories:
Import the RPMforge GPG key:
rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
On x86_64 systems:
yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
On i386 systems:
yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
phpMyAdmin can now be installed as follows:
yum install phpmyadmin
Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):
nano /etc/httpd/conf.d/phpmyadmin.conf
#
# Web application to manage MySQL
#
#<Directory "/usr/share/phpmyadmin">
# Order Deny,Allow
# Deny from all
# Allow from 127.0.0.1
#</Directory>
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin
Next we change the authentication in phpMyAdmin from cookie to http:
nano /usr/share/phpmyadmin/config.inc.php
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]
Restart Apache:
/etc/init.d/httpd restart
Afterwards, you can access phpMyAdmin under http://your-ip/phpmyadmin/
That's all folks, I hope that this helps to make Web Server for RO up and running.
