====MySQL====
===Install===
==CentOS or [[RedHat Red Hat]] RHEL (Extras)==
Install the MySql package when you install CentOS or [[RedHat Red Hat]] RHEL (Extras)
==Debian, Ubuntu or Xubuntu==
Run Synaptic and choose the mysql package
===Secure===
Initially there are two MySql 'root' accounts (not the same as your *nix root) and two Anonymous accounts
You will probably want to set passwords on the 'root' accounts and delete the anonymous accounts
%%
# service mysqld start
# mysql -u root
mysql> use mysql
mysql> select user,host,password from user;
| user | host                  | password |
| root | localhost             |          |
| root | localhost.localdomain |          |
|      | localhost             |          |
|      | localhost.localdomain |          |
4 rows in set (0.01 sec)
mysql> quit
%%
====MySQL Initialise Passwords====
%%
# mysqladmin -u root password "mypassword"
# mysqladmin -u root -h <localhost.localdomain> password "mypassword"
%%
Now that you've set a password you'll need to use it EVERY time !
====MySQL Initialise Anonymous Passwords====
%%
# mysql -u root -p
Enter password:
mysql> SET PASSWORD FOR ''@'localhost' = PASSWORD('mypassword');
mysql> SET PASSWORD FOR ''@'<localhost.localdomain>' = PASSWORD('mypassword');
mysql> quit
%%
====MySQL Delete Anonymous Accounts====
%%
# mysql -u root -p 
Enter password:
mysql> use mysql
mysql> DELETE FROM mysql.user WHERE User = '';
mysql> FLUSH PRIVILEGES;
mysql> quit
%%
====MySQL verify that root has passwords and anaonymous accounts have been deleted====
%%
# mysql -u root -p 
Enter password:
mysql> use mysql
mysql> select user,host,password from user;
| user | host                  | password         |
| root | localhost             | **************** |
| root | localhost.localdomain | **************** |
2 rows in set (0.01 sec)
mysql> quit
%%

==MySQL 5==
By default MySQL 5 is only bound to listen to and only accept requests from localhost 127.0.0.1
If you want to connect from a separate pc/server
%%
# vi /etc/mysql/my.cnf
bind-address = 127.0.0.1 change to <your.ip.addr>
%%
