Automatic Plone (re)starts
(Plone の自動(再)起動)¶
再起動スクリプト¶
Restart command for Plone installations is yourbuildoutfolder/bin/instance restart.
It is best practice to run Plone under non-root user. Thus you need a special restart script which will sudo to this user to perform the restart command. Due to egg cache problems, HOME environment variable must be considered when switching users.
Example /srv/plone/yoursite/restart-all.sh:
#!/bin/sh
echo Going to user yourploneuser
cd /srv/plone/yoursite
sudo -H -u yourploneuser bin/instance restart
ノート
restart-all.sh must be modded chmod u+x.
Start on boot¶
It is best practice to start Plone service if the server is rebooted. This way your site will automatically recover from power loss etc.
rc.local script¶
For Debian based Linuxes, put the following line to /etc/rc.local script:
/srv/plone/yoursite/restart-all.sh
Nightly restart¶
Plone 3 leaks memory. It is best practice to restart the instance nightly, or eventually you will run out of swap space. Before running out of swap space, everything will come to grinding halt.
If nightly restart is not an option and you need high-availability instance, consider using ZEO clustering and restart instances one-by-one with certain intervals.
Cron restart script¶
Cron is UNIX scheduled taks daemon,
There instructions apply for Debian based Linuxes.
Example /etc/cron.d/site script:
# Restart varnish + deliverance + plone
# run every night
0 22 * * * root /srv/plone/yoursite/restart-all.sh
