Added by Daniel Dehennin almost 2 years ago

MySQL must start only when time is synchronised

  • systemd/mysql.service.d/override.conf: start after
    “network-online.target” and “time-sync.target”
  • eole-mysql.mk: install systemd unit override file.

Ref: #25565

Revision 376da523 (diff)
Added by Daniel Dehennin almost 2 years ago

Package “mysql.service” override in “eole-mysql-pkg”

  • debian/eole-mysql.install: specify the installation of
    /etc/logrotate.d/ to avoid packaging the systemd override file.
  • debian/eole-mysql-pkg.install: install the systemd unit override
    file.
  • debian/eole-mysql-pkg.postinst: reload the systemd configuration.

Ref: #25565

Revision 7735ae8e (diff)
Added by Daniel Dehennin almost 2 years ago

The “mysql.service” override is under “/etc/systemd/system/”
