Erwan Velu 737ffd1c19 install: Fixing code typo
The last bracket shall not be glued to the directory.

The actual code is generating a runtime error like the following :
 erwan@raspberrypi:~/download/log2ram $ sudo ./install.sh
 Created symlink /etc/systemd/system/sysinit.target.wants/log2ram.service → /etc/systemd/system/log2ram.service.
 ./install.sh: 19: [: missing ]
 ##### Reboot to activate log2ram #####

This patch simply adds the missing space to make this script work.

Log2Ram

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

Install

git clone https://github.com/azlux/log2ram.git
cd log2ram
chmod +x install.sh
sudo ./install.sh

REBOOT before installing anything else (for example apache2)

Customize

variables :

In the file /etc/log2ram.conf, there are three variables:

  • SIZE: defines the size the log folder will reserve into the RAM.
  • USE_RSYNC: Can be set to true if you prefer "rsync" rather than "cp". I use the command cp -u and rsync -X, I don't copy the all folder every time for optimization.
  • MAIL: Disables the error system mail if there is not enough place on RAM (if set to false)

refresh time:

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
mount

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: /var/hdd.log/log2ram.log

Now, muffins for everyone!

Uninstall :(

(Because sometime we need it)

cd log2ram
chmod +x uninstall.sh
sudo ./uninstall.sh
