1、mariadb安裝
[root@localhost ~]# yum -y install mariadb mariadb-server
#安裝完成後啓動mariadb並添加到自啓動
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# systemctl enable mariadb
#mariadb設置:root密碼等
[root@localhost ~]# mysql_secure_installation
1、設置密碼，首次進入無密碼，直接回車
Enter current password for root (enter for none): 回車
OK, successfully used password, moving on...
2、設置root密碼
Set root password? [Y/n] y
New password: 輸入root密碼
Re-enter new password: 輸入root密碼
Password updated successfully!
Reloading privilege tables..
... Success!
3、是否刪除匿名用戶
Remove anonymous users? [Y/n] 回車
... Success!
4、是否禁止root遠程登錄
Disallow root login remotely? [Y/n]
... Success!
5、是否刪除test數據庫

- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
6、是否重新加載權限表
Reload privilege tables now? [Y/n]
... Success!
Cleaning up...
mariadb安裝完成，使用mysql -uroot -p登錄測試
2、mariadbz字符集配置
修改/etx/my.cnf,在[mysqld]下添加
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
修改/etc/my.cnf.d/client.cnf，在[client]中添加
default-character-set=utf8
修改/etc/my.cnf.d/mysql-clients.cnf，在[mysql]中添加
default-character-set=utf8
重啓mariadb
[root@localhost ~]# systemctl restart mariadb
進入mariadb查看字符集
MariaDB [(none)]> show variables like "%character%";show variables like "%collat ion%";
+--------------------------+----------------------------+
| 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/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database | utf8_unicode_ci |
| collation_server | utf8_unicode_ci |
+----------------------+-----------------+
3 rows in set (0.01 sec)
3、用戶、權限設置
配置root允許遠程訪問
MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'root' WITH GRANT OPTION;
Query OK, 0 rows affected (0.03 sec)
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
創建用戶命令
create user username@localhost identified by 'password';
直接創建用戶並授權的命令
grant all privileges on *.* to test@'%' identified by 'test';
授予外網登陸權限
grant all privileges on *.* to username@'%' identified by 'password';
授予權限並且可以授權
grant all privileges on *.* to username@'192.168.100.200' identified by 'password' with grant option;
