# 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](https://github.com/azlux/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](https://www.debian-administration.org/article/661/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 :
|
|
Into the file `/etc/log2ram.conf`, there are three variables :
|
|
|
|
- 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". I use the command `cp -u` and `rsync -X`, I don't copy the all folder every time for optimization.
|
|
- The last varibale disable the error system mail if there are no enought place on RAM (if set on false)
|
|
|
|
#### refresh time:
|
|
The default is to write log into the HardDisk every hour. If you think this is too much, you can make the write every day by moving the cron file : `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 into /etc/systemd/system/log2ram.service it will solve the pb
|
|
|
|
The log for log2ram will be write here : `/var/log/log2ram.log`
|
|
|
|
