# 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](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 :
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
```
