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 |
