一、安装MariaDB1、安装$ yum -y install mariadb mariadb-server2、启动MariaDB$ systemctl start mariadb3、设置开机启动$
一、安装MariaDB
1、安装
$ yum -y install mariadb mariadb-server
2、启动MariaDB
$ systemctl start mariadb
3、设置开机启动
$ systemctl enable mariadb
4、配置安全策略
$ mysql_secure_installation首先设置密码,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
5、登陆
$ mysql -uroot -p <– 回车后输入密码
二、配置MariaDB的字符集
1、文件/etc/my.cnf
$ vim /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
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,重启mariadb
systemctl restart mariadb
5、进入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、添加用户,设置权限
1、创建用户命令
mysql>create user username@localhost identified by 'password';
2、直接创建用户并授权的命令
mysql>grant all on *.* to username@localhost indentified by 'password';
3、授予外网登陆权限
mysql>grant all privileges on *.* to username@'%' identified by 'password';
4、授予权限并且可以授权
mysql>grant all privileges on *.* to username@'hostname' identified by 'password' with grant option;
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;
多个用逗号。
