MySQL anonymous accounts – User=”, Host=’%’ – CODE RED
+0 Vote Up -0Vote Down

I want to highlight the importance of reviewing mysql’s initial set of accounts.
Say you have a mysql on abc.def.ghi.jkl running on port 3306 anonymous account with privileges without a password, then:

2. mysql -h abc.def.ghi.jkl
3. mysql -u ” -h abc.def.ghi.jkl
4. mysql -u ” -h abc.def.ghi.jkl -P 3306
5. mysql -u user_which_does_not_exist -h abc.def.ghi.jkl

instance 1 has a datadir of /data/mysql/instance1
instance 2 has a datadir of /data/mysql/instance2

Now, the unix tool strings can be used against many types of files. In particular, though, you can use …

MySQL Proxy: Roles
Employee +2 Vote Up -0Vote Down

On the MySQL Proxy channel we get questions from time to time if the authentication can be intercepted and replaced data from a external source.

From now on, you can. For example if you want to get data from a external source (like LDAP) or want to implement roles.

Mapping Accounts to “Roles”

There isn’t much needed to implement Roles for MySQL with the help of the MySQL Proxy.

  • mysql.user doesn’t contain users, but roles instead
  • the proxy maps user-accounts to role-accounts with a script like above

It works like this:

  1. login to the proxy
