Like ramlog for systemd (on debian 8 jessie for example).
Usefull for RaspberryPi for not writing on the SD card all the time. You need it because your SD card doesn't want to suffer anymore!
The script log2ram can work on every linux system. So you can use it with your own daemon manager if you don't have systemd.
Log2Ram is based on transient log for Systemd here : A transient /var/log
curl -Lo log2ram.tar.gz https://github.com/azlux/log2ram/archive/master.tar.gz tar xf log2ram.tar.gz cd log2ram-master chmod +x install.sh && sudo ./install.sh cd .. rm -r log2ram-master
REBOOT before installing anything else (for example apache2)
You need to stop log2ram (
service log2ram stop) and start the install.
In the file
/etc/log2ram.conf, there are three variables:
SIZE: defines the size the log folder will reserve into the RAM (default is 40M).
USE_RSYNC: Can be set to
trueif you prefer ´rsync´ rather than ´cp´. I use the command
rsync -X, I don't copy the all folder every time for optimization.
By default Log2Ram writes to the HardDisk every hour. If you think this is too much, you can make the write every day by moving the cron file to daily:
sudo mv /etc/cron.hourly/log2ram /etc/cron.daily/log2ram.
It is working?
You can now check the mount folder in ram with (You will see lines with log2ram if working)
# df -h … log2ram 40M 532K 40M 2% /var/log … # mount … log2ram on /var/log type tmpfs (rw,nosuid,nodev,noexec,relatime,size=40960k,mode=755) …
If you have issue with apache2, you can try to add
apache2.service next to other services on the
Before parameter in
/etc/systemd/system/log2ram.service it will solve the pb
The log for log2ram will be written at:
Now, muffins for everyone!
(Because sometime we need it)
chmod +x /usr/local/bin/uninstall-log2ram.sh && sudo /usr/local/bin/uninstall-log2ram.sh
