1、安装MariaDB
安装命令
yum -y install mariadb mariadb-server
安装完成MariaDB,首先启动MariaDBsystemctl start mariadb
设置开机启动systemctl enable mariadb
接下来进行MariaDB的相关简单配置mysql_secure_installation
首先是设置密码,会提示先输入密码Enter current password for root (enter for none):<–初次运行直接回车
设置密码
Set root password? [Y/n] <– 是否设置root用户密码,输入y并回车或直接回车
New password: <– 设置root用户的密码 Re-enter new password: <– 再输入一次你设置的密码其他配置
Remove anonymous users? [Y/n] <– 是否删除匿名用户,回车
Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,
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
完成。2、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.cnfvi /etc/my.cnf.d/client.cnf
在[client]中添加default-character-set=utf8
文件/etc/my.cnf.d/mysql-clients.cnfvi /etc/my.cnf.d/mysql-clients.cnf
在[mysql]中添加default-character-set=utf8
全部配置完成,重启mariadbsystemctl restart mariadb
之后进入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。
3、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。
