A very cool thing: Install MYSQL from source without root access on LINUX

# Here is entries for some specific programs # The following values assume you have at least 32M ram # This was formally known as [safe_mysqld]. Both versions are currently parsed.

六、启动

./mysqld_safe --defaults-file=/home/guofeng/local/etc/mysql/my.cnf --skip-grant-tables&

ps -ef | grep mysql

七、进入数据库

mysql -u root -p

随便输入一个密码

进去之后创建一个新的用户[2]

创建用户，授权.
Sql代码
create user lzquan identified by ‘123456‘;

 grant all privileges on *.* to ‘lzquan‘@‘localhost‘ identified by ‘123456‘;

 flush privileges;

Sql代码
 删除用户,收回权限
Sql代码
delete from mysql.user where user=‘lzquan‘ and host=‘localhost‘;

 revoke all on testuser .* from ‘lzquan‘@localhost;
