Invalid config file template for version 5.7 in installer manifest

[Maxime Therreault]

I have a script that execute the installer console to install the community edition of MySQL Server 5.7.11.

When the product is already installed, the config file still generated (and backuped) using the installer templates coming from the product manifest archive.

Today, the installer decided to update the product manifest by downloading the new archive.

The configuration file generated during the installation process is invalid and prevented MySQL to restart after the installation.

The new template contains new configuration options for INNODB engine that seems unknown to MySQL 5.7.

Here the error in the server '.err' file at startup:

...
2017-04-14T18:27:52.818186Z 0 [ERROR] unknown variable 'innodbclustertypeselection=0.0'
2017-04-14T18:27:52.818186Z 0 [ERROR] Aborting
...


Here what was newly inserted at the end of the 'my.ini' config file:

...
# Indicates how is the InnoDB Cluster configured as (Classic, Sandbox, Master or Slave).
innodbclustertypeselection=0.0

# Indicates how is the InnoDB Cluster is/will be named.
innodbclustername=0.0

innodbclusterinstances=0.0

# Holds the InnoDB Cluster Username.
innodbclusterusername=0.0

# Indicates the InnoDB Cluster URI.
innodbclusteruri=0.0

# Indicates the InnoDB Cluster Port.
innodbclusterport=0.0
