Log2Ram

Like ramlog for systemd (on debian 8 jessie for example).

Usefull for Raspberry for not writing all the time on the SD card. You need it because your SD card don’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

into /usr/local/bin/log2ram

• You can change the SIZE variable if necessary
• If you prefer to use rsync, you can set the USE_RSYNC variable to true

Customize

services :

If you open the file /etc/systemd/system/log2ram.service , you will see a line starting by Before=, you can list here the services who need to start after log2ram. You will need to change this line when a service start too fast and stop running because log2ram mount a ram folder where it has start to write log.

For example, If you use apache instead of nginx, add apache2.service into this line.

variables :

Into the file log2ram (or /usr/local/bin/log2ram if you have already installed it), there are two variables into the script : SIZE=40M and USE_RSYNC=false

The first variable define the size the log folder will reserve into the RAM.

The second variable can be set to true if you prefer “rsync” than “cp”.

###It is working ? You can now check the mount folder in ram with

df -h
mount

By default, the program will write log into the HardDisk every hour and the log for log2ram will be write here : /var/log.hdd/log2ram.log
