1) 安装数据库
[root@srv1 ~]# yum install mariadb-server -y
[root@srv1 ~]# vim /etc/my.cnf
# 于[mysqld]区段最后追加如下内容(定义字符集为utf8)
......
......
character-set-server=utf8
[root@srv1 ~]# systemctl enable --now mariadb
2) 初始化数据库
[root@srv1 ~]# mysql_secure_installation
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.
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.
# 设定root密码
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.
# 移除匿名账户
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.
# 禁止root远程登录
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.
# 移除test数据库
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.
# 刷新授权
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!
3) 创建Openfire数据库
[root@srv1 ~]# mysql -u root -p
Enter password:
......
......
MariaDB [(none)]> create database openfire;
Query OK, 1 rows affected (0.00 sec)
MariaDB [(none)]> grant all privileges on openfire.* to openfire@'localhost' identified by 'password';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all privileges on openfire.* to openfire@'%' identified by 'password';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> exit
Bye
