1、安裝MariaDB
安裝命令
yum -y install mariadb mariadb-server
安裝完成MariaDB，首先啓動MariaDB
systemctl start mariadb
設置開機啓動
systemctl enable mariadb
接下來進行MariaDB的相關簡單配置
mysql_secure_installation
首先是設置密碼，會提示先輸入密碼
Enter current password for root (enter for none):<–初次運行直接回車
設置密碼
Set root password? [Y/n] <– 是否設置root用戶密碼，輸入y並回車或直接回車
New password: <– 設置root用戶的密碼
Re-enter new password: <– 再輸入一次你設置的密碼
其他配置
Remove anonymous users? [Y/n] <– 是否刪除匿名用戶，回車
Disallow root login remotely? [Y/n] <–是否禁止root遠程登錄,回車,
Remove test database and access to it? [Y/n] <– 是否刪除test數據庫，回車
Reload privilege tables now? [Y/n] <– 是否重新加載權限表，回車
初始化MariaDB完成，接下來測試登錄
mysql -uroot -ppassword
完成。
2、配置MariaDB的字符集
文件/etc/my.cnf
vi /etc/my.cnf
在[mysqld]標籤下添加
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
文件/etc/my.cnf.d/client.cnf
vi /etc/my.cnf.d/client.cnf
在[client]中添加
default-character-set=utf8
文件/etc/my.cnf.d/mysql-clients.cnf
vi /etc/my.cnf.d/mysql-clients.cnf
在[mysql]中添加
default-character-set=utf8
全部配置完成，重啓mariadb
systemctl restart mariadb
之後進入MariaDB查看字符集
mysql> show variables like "%character%";show variables like "%collation%";
顯示爲
+--------------------------+----------------------------+
| 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 (0.00 sec)
字符集配置完成。
3、添加用戶，設置權限
創建用戶命令
mysql>create user username@localhost identified by 'password';
直接創建用戶並授權的命令
mysql>grant all on *.* to username@localhost indentified by 'password';
授予外網登陸權限
mysql>grant all privileges on *.* to username@'%' identified by 'password';
授予權限並且可以授權
mysql>grant all privileges on *.* to username@'hostname' identified by 'password' with grant option;
簡單的用戶和權限配置基本就這樣了。
其中只授予部分權限把 其中 all privileges或者all改爲select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file其中一部分。
