[root@hadoop001 local]# groupadd -g 101 dba

[root@hadoop001 local]# id mysqladmin

## 一般不需要设置mysqladmin的密码，直接从root或者LDAP用户sudo切换
[root@hadoop001 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password: 
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password: 
passwd: all authentication tokens updated successfully.
## 如果mysqladmin用户存在 使用下面的命令
[root@hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
