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.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
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 PRIVILEGES ON . TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
授予外网登陆权限
mysql>flush privileges;
刷新权限
