Adjust the mysql-log-rotate script in several ways:
|
|
|
9c7c797 |
|
|
|
9c7c797 |
* Use the correct log file pathname for Red Hat installations.
|
|
|
9c7c797 |
* Enable creation of the log file by logrotate (needed since
|
|
|
9c7c797 |
/var/log/ isn't writable by mysql user); and set the same 640
|
|
|
9c7c797 |
permissions we normally use.
|
|
|
9c7c797 |
* Comment out the actual rotation commands, so that user must edit
|
|
|
9c7c797 |
the file to enable rotation. This is unfortunate, but the fact
|
|
|
9c7c797 |
that the script will probably fail without manual configuration
|
|
|
9c7c797 |
(to set a root password) means that we can't really have it turned
|
|
|
9c7c797 |
on by default. Fortunately, in most configurations the log file
|
|
|
9c7c797 |
is low-volume and so rotation is not critical functionality.

Update 3/2017
|
|
|
7998c8e |
* it would be big unexpected change for anyone upgrading, if we start shipping it now.
|
|
|
7998c8e |
Maybe it is good candidate for shipping with MariaDB 10.2 ?
|
|
|
7998c8e |
* the 'mysqladmin flush logs' doesn´t guarantee, no entries are lost
|
|
|
7998c8e |
during flushing, the operation is not atomic.
|
|
|
7998c8e |
We should not ship it in that state

* the SIGHUP causes server to flush all logs. No password admin needed, the only constraint is
|
|
|
5007ecd |
beeing able to send the SIGHUP to the process and read the mysqld pid file, which root can.
