# mysql_conf
|
|
|
|
Use the `mysql_conf` InSpec audit resource to test the contents of the configuration file for MySQL, typically located at `/etc/mysql/my.cnf` or `/etc/my.cnf`.
|
|
|
|
## Syntax
|
|
|
|
A `mysql_conf` resource block declares one (or more) settings in the `my.cnf` file, and then compares the setting in the configuration file to the value stated in the test:
|
|
|
|
describe mysql_conf('path') do
|
|
its('setting') { should eq 'value' }
|
|
end
|
|
|
|
where
|
|
|
|
* `'setting'` specifies a setting in the `my.cnf` file, such as `max_connections`
|
|
* `('path')` is the non-default path to the `my.cnf` file
|
|
* `should eq 'value'` is the value that is expected
|
|
|
|
|
|
## Matchers
|
|
|
|
This InSpec audit resource has the following matchers:
|
|
|
|
### be
|
|
|
|
<%= partial "/shared/matcher_be" %>
|
|
|
|
### cmp
|
|
|
|
<%= partial "/shared/matcher_cmp" %>
|
|
|
|
### eq
|
|
|
|
<%= partial "/shared/matcher_eq" %>
|
|
|
|
### include
|
|
|
|
<%= partial "/shared/matcher_include" %>
|
|
|
|
### match
|
|
|
|
<%= partial "/shared/matcher_match" %>
|
|
|
|
### setting
|
|
|
|
The `setting` matcher tests specific, named settings in the `my.cnf` file:
|
|
|
|
its('setting') { should eq 'value' }
|
|
|
|
Use a `setting` matcher for each setting to be tested.
|
|
|
|
## Examples

|
|
|
### Test the maximum number of allowed connections
|
|
|
|
describe mysql_conf do
|
|
its('max_connections') { should eq '505' }
|
|
its('max_user_connections') { should eq '500' }
|
|
end
|
|
|
|
### Test slow query logging**

|
|
|
describe mysql_conf do
|
|
its('slow_query_log_file') { should eq 'hostname_slow.log' }
|
|
its('slow_query_log') { should eq '0' }
|
|
its('log_queries_not_using_indexes') { should eq '1' }
|
|
its('long_query_time') { should eq '0.5' }

|
its('min_examined_row_limit') { should eq '100' }
|
|
end
|
|
|
|
### Test the port and socket on which MySQL listens
|

|
|
describe mysql_conf do
|
|
its('port') { should eq '3306' }

|
its('socket') { should eq '/var/run/mysqld/mysql.sock' }
|
|
end
|
|
|
|
### Test connection and thread variables
