## initscripts rely on mysqladmin from a different package
|
||
|
|
We have the problem that "/etc/init.d/mysql stop" relies on mysqladmin which
|
||
|
|
is in another package (mysql-client) and a passwordless access that's maybe
|
||
|
|
only available if the user configured his /root/.my.cnf. Can this be a problem?
|
||
|
|
* normal mode: not because the user is required to have it. Else:
|
||
|
|
* purge/remove: not, same as normal mode
|
||
|
|
* upgrade: not, same as normal mode
|
||
|
|
* first install: not, it depends on mysql-client which at least is unpacked
|
||
|
|
so mysqladmin is there (to ping). It is not yet configured
|
||
|
|
passwordles but if there's a server running then there's a
|
||
|
|
/root/.my.cnf. Anyways, we simply kill anything that's mysqld.
|
||
|
|
|
||
|
|
## Passwordless access for the maintainer scripts
|
||
|
|
Another issue is that the scripts needs passwordless access. To ensure this
|
||
|
|
a debian-sys-maint user is configured which has process and shutdown privs.
|
||
|
|
The file with the randomly (that's important!) generated password must be
|
||
|
|
present as long as the databases remain installed because else a new install
|
||
|
|
would have no access. This file should be used like:
|
||
|
|
mysqladmin --defaults-file=/etc/mysql/debian.cnf restart
|
||
|
|
to avoid providing the password in plaintext on a commandline where it would
|
||
|
|
be visible to any user via the "ps" command.
|
||
|
|
|
||
|
|
## When to start the daemon?
|
||
|
|
We aim to give the admin full control on when MySQL is running.
|
||
|
|
Issues to be faced here:
|
||
|
|
OLD:
|
||
|
|
1. Debconf asks whether MySQL should be started on boot so update-rc.d is
|
||
|
|
only run if the answer has been yes. The admin is likely to forget
|
||
|
|
this decision but update-rc.d checks for an existing line in
|
||
|
|
/etc/runlevel.conf and leaves it intact.
|
||
|
|
2. On initial install, if the answer is yes, the daemon has to be started.
|
||
|
|
3. On upgrades it should only be started if it was already running, everything
|
||
|
|
else is confusing. Especiall relying on an debconf decision made month ago
|
||
|
|
is considered suboptimal. See bug #274264
|
||
|
|
Implementation so far:
|
||
|
|
prerm (called on upgrade before stopping the server):
|
||
|
|
check for a running server and set flag if necessary
|
||
|
|
preinst (called on initial install and before unpacking when upgrading):
|
||
|
|
check for the debconf variable and set flag if necessary
|
||
|
|
postinst (called on initial install and after each upgrade after unpacking):
|
||
|
|
call update-rc.d if debconf says yes
|
||
|
|
call invoce-rc.d if the flag has been set
|
||
|
|
Problems remaining:
|
||
|
|
dpkg-reconfigure and setting mysql start on boot to yes did not start mysql
|
||
|
|
(ok "start on boot" literally does not mean "start now" so that might have been ok)
|
||
|
|
NEW:
|
||
|
|
1. --- no debconf anymore for the sake of simplicity. We have runlevel.conf,
|
||
|
|
the admin should use it
|
||
|
|
2. On initial install the server is started.
|
||
|
|
3. On upgrades the server is started exactly if it was running before so the
|
||
|
|
runlevel configuration is irrelevant. It will be preserved by the mean of
|
||
|
|
update-rc.d's builtin check.
|
||
|
|
Implementation:
|
||
|
|
prerm (called on upgrade before stopping the server):
|
||
|
|
check for a running server and set flag if necessary
|
||
|
|
preinst (called on initial install and before unpacking when upgrading):
|
||
|
|
check for $1 beeing (initial) "install" and set flag
|
||
|
|
postinst (called on initial install and after each upgrade after unpacking):
|
||
|
|
call update-rc.d
|
||
|
|
call invoce-rc.d if the flag has been set
