mysql初始化

delete from mysql.user where user=‘‘;

update mysql.user set password=password(‘123‘) where user=‘root‘;delete from mysql.db where user=‘‘;

flush privileges;

2、创建数据库并授权给用户

create database mysqldb default charset utf8;

grant all on mysqldb.* to username@localhost identified by ‘123‘;

3、对于并发数高时需要修改mysql的最大连接数，否则会报错，最大值16384

查看最大连接数
show variables like ‘%max_connections%‘;

修改最大连接数

set GLOBAL max_connections = 1000;
