acc lte database -c 安裝 reference enc tab res 一、安裝MariaDB
1、安裝
$ yum -y install mariadb mariadb-server
2、啟動MariaDB
$ systemctl start mariadb
3、設置開機啟動
$ systemctl enable mariadb
4、配置安全策略
$ mysql_secure_installation 首先設置密碼,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
5、登陸
$ mysql -uroot -p <– 回車後輸入密碼
二、配置MariaDB的字符集
1、文件/etc/my.cnf
$ vim /etc/my.cnf 在[mysqld]標簽下添加 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
2、文件/etc/my.cnf.d/client.cnf
$ vim /etc/my.cnf.d/client.cnf
在[client]中添加
default-character-set=utf8
3、文件/etc/my.cnf.d/mysql-clients.cnf
$vim /etc/my.cnf.d/mysql-clients.cnf
在[mysql]中添加
default-character-set=utf8
4、全部配置完成,重啟mariadb
systemctl restart mariadb
5、進入MariaDB查看字符集
mysql> show variables like "%character%";show variables like "%collation%"; +--------------------------+----------------------------+ | 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。
三、添加用戶,設置權限
1、創建用戶命令
mysql>create user username@localhost identified by ‘password‘;
2、直接創建用戶並授權的命令
mysql>grant all on *.* to username@localhost indentified by ‘password‘;
3、授予外網登陸權限
mysql>grant all privileges on *.* to username@‘%‘ identified by ‘password‘;
4、授予權限並且可以授權
mysql>grant all privileges on *.* to username@‘hostname‘ identified by ‘password‘ with grant option;
只授予部分權限
把其中all privileges或者all改為select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file;
多個用逗號。
