1、安装MariaDB 安装命令 yum -y install mariadb mariadb-server 安装完成MariaDB，首先启动MariaDB systemctl 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。 开放root远程权限 GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.148.%' IDENTIFIED BY '12345678' WITH GRANT OPTION; 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。 原文链接：https://www.f2er.com/centos/375849.html
