The typical Unix startup/shutdown cycle for a MySQL server with the MySQL Instance Manager
enabled is as follows:
1. The
/etc/init.d/mysql
2. Instance Manager starts the guarded server instances and monitors them.
3. If a server instance fails, Instance Manager restarts it.
4. If Instance Manager is shut down (for example, with the

4.6.10.4. Instance Manager User and Password Management
The Instance Manager stores its user information in a password file. On Windows, the default is
mysqlmanager.passwd
file is /etc/mysqlmanager.passwd. To specify a different location for the password file, use the
password-file
If the password file does not exist or contains no password entries, you cannot connect to the Instance
Manager.
Entries in the password file have the following format, where the two fields are the account user name
and encrypted password, separated by a colon:
petr:*35110DC9B4D8140F5DE667E28C72DD2597B5C848

operation; no means are provided for decrypting encrypted passwords.

• MySQL Server accounts are associated with a host name, user name, and password (see
Section 6.3.1, "User Names and
• Instance Manager accounts are associated with a user name and password only.
