MySQL创建数据库时指定编码utf8mb4和添加用户
CREATE DATABASE `wordpress` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE DATABASE `wordpress` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
- 修改/etc/my.cnf 文件
[client]
default-character-set = utf8mb4
[mysqld]
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
[mysql]
default-character-set = utf8mb4
- 重启Mysql服务 /etc/init.d/mysqld stop /etc/init.d/mysqld start
####添加用户及授权部分
Mysql创建、删除用户
授权test用户拥有testDB数据库的所有权限(某个数据库的所有权限):
mysql>grant all privileges on testDB.* to test@localhost identified by ‘1234’;
mysql>flush privileges;//刷新系统权限表
格式:grant权限 on 数据库.* to 用户名@登录主机 identified by “密码”;
- 如果想指定部分权限给一用户,可以这样来写:
mysql>grant select,update on testDB.* to test@localhost identified by ‘1234’;
- 授权test用户拥有所有数据库的某些权限:
mysql>grant select,delete,update,create,drop on . to test@”%” identified by “1234”;
//test用户对所有数据库都有select,delete,update,create,drop 权限。
//对localhost授权:加上一句grant all privileges on testDB.* to test@localhost identified by ‘1234’;即可。
