设置开机启动
systemctl enable mariadb
MariaDB的相关简单配置
- 初始化
mysql_secure_installation
- 首先是设置密码，会提示先输入密码

Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车
Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车
- 初始化MariaDB完成，接下来测试登录
mysql -uroot -ppassword
配置MariaDB的字符集
- 文件/etc/my.cnf
vi /etc/my.cnf
在[mysqld]标签下添加
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，重启mariadb
systemctl restart mariadb
- 进入MariaDB查看字符集
mysql> show variables like "%character%";show variables like "%collation%";
显示为
| 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。
添加用户，设置权限
创建用户命令
mysql>create user username@localhost identified by 'password';
直接创建用户并授权的命令
mysql>grant all on \*.\* to username@localhost indentified by 'password';
授予外网登陆权限
mysql>grant all privileges on \*.\* to username@'%' identified by 'password';
授予权限并且可以授权
mysql>grant all privileges on \*.\* to username@'hostname' identified by 'password' with grant option;
简单的用户和权限配置基本就这样了。
其中只授予部分权限把 其中 all privileges或者all改为select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file其中一部分。
远程连接授权：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
授权后执行
flush privileges
