The following steps will guide you through the installation of MySQL on RedHat / Fedora systems :
* Install MySQL :
{noformat}
# yum install mysql-server mysql
{noformat}
* Launch MySQL
{noformat}
/etc/init.d/mysql start
{noformat}
* Change the default password :
{noformat}
mysqladmin -u root password petals
{noformat}
* Test database connectivity :
{noformat}
mysql -u root -p
{noformat}
* Clean up the installation :
{noformat}
mysql> drop database test;
{noformat}
h2. MySQL use
This chapter will give you some basic commands to launch, stop, reload MySQL. For more advanced documentation, feel free to check the [MySQL website|http://www.mysql.com/].
h3. Linux systems
Checking the MySQL status :
{noformat}
/etc/init.d/mysqld status
{noformat}
Launch MySQL
{noformat}
/etc/init.d/mysql start
{noformat}
Stop MySQL
{noformat}
/etc/init.d/mysql stop
{noformat}
Restart MySQL
{noformat}
/etc/init.d/mysql restart
{noformat}
Reload MySQL configuration
{noformat}
/etc/init.d/mysql reload
{noformat}
Force-Reload MySQL configuration
{noformat}
/etc/init.d/mysql force-reload
{noformat}
h2. Configuring MySQL character set
By default, Petals ESB uses the UTF8 character set, which is not the default character set of MySQL. This chapter will help you to configure MySQL to use this character set.
h3. Linux systems
* Add the following to lines at the end of the section "{{\[mysqld]}}" of the file */etc/my.cnf* (copy */usr/share/mysql/my-huge.cnf* dans */etc/my.cnf*)
{noformat}
character-set-server=utf8
skip-character-set-client-handshake
{noformat}
* Restart MySQL :
{noformat}
/etc/init.d/mysql restart
{noformat}
* Open a new connection to MySQL :
{noformat}
mysql -u root -p
{noformat}
* Execute the following command :
{noformat}
SHOW VARIABLES LIKE 'char%';
{noformat}
* Check if it's result looks like this :
{noformat}
mysqld> SHOW VARIABLES LIKE 'char%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysqld/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
{noformat}
* Done :)
h2. Creating & configuring a new database
* Open a new connection to MySQL :
{noformat}
mysql -u root -p
{noformat}
* Create a new database for Petals :
{noformat}
mysql> create database petals;
{noformat}
* Check whether or not the database has been successfully created you can execute the following command :
{noformat}
mysql> show databases;
{noformat}
* Create a new user to write to the newly created database :
{noformat}
mysql> create user "petals"@"localhost";
mysql> set password for "petals"@"localhost" = password("petals");
{noformat}
* Set up the permissions for this user, so that he can read and write datas to the newly created database :
{noformat}
mysql> grant all on petals.* to petals@localhost;
mysql> exit
{noformat}
* Check if this user can open a new connection to this database :
{noformat}
mysql -u petals -p
mysql> connect petalsRegistry;
mysql> exit
{noformat}
* Done :)
