centos7系統安裝mysql（MariaDB）的教程
1.centos7現狀：
新系統無法直接使用yum install mysql-server來安裝mysql（需要新增mysql yum源），因為已使用mariadb代替mysql。
2.安裝mariadb：
[root@localhost ~]
# yum -y install mariadb*
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.linode.com
* extras: mirrors.linode.com
* updates: mirrors.linode.com

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password
for
the root user. If you've just installed MariaDB, and
you haven't
set
the root password yet, the password will be blank,
so you should just press enter here.
ERROR 1045 (28000): Access denied
for
user
'root'
@
'localhost'
(using password: YES)
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 MariaDB
root user without the proper authorisation.
Set root password? [Y
/n
] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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, MariaDB 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 MariaDB
installation should now be secure.
Thanks
for
using MariaDB!
