mysql>grant select on *.* to read@'%' identified by 'j'; //给予read用户只读全部库的权限
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。
mysql>flush privileges; //刷新系统权限表
//@"%" 表示对所有非本地主机授权,不包括localhost。
//对localhost授权:加上一句grant all privileges on testDB.* to test@localhost identified by '1234';即可。
格式:grant 权限 on 数据库.* to 用户名@登录主机 identified by "密码";
开启慢查询my.cnf 加入下来代码
slow_query_log=1 //开启慢查询
long_query_time=1 //超过1s记录
slow_query_log_file=/usr/local/mysql/slowquery.log //记录的log文件地址
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.60.17' IDENTIFIED BY 'cc.123' WITH GRANT OPTION;
执行上面命令还是不能远程连接
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.60.17' IDENTIFIED BY 'cc.123';
再执行上面的命令,就可以用客户端连接了!
SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
给与授权权限:
GRANT USAGE ON *.* TO 'root'@'%' WITH GRANT OPTION;
SET GLOBAL slow_query_log=ON SET long_query_time=4;
