|
|
|
## Web Server ##
|
|
|
|
### Configure PHP
|
|
|
|
Ensure date.timezone is set in php.ini to your preferred time zone. See http://php.net/manual/en/timezones.php for a list of supported timezones. Valid examples are: "America/New_York", "Australia/Brisbane", "Etc/UTC".
|
|
|
|
vi /etc/php/7.0/apache2/php.ini
|
|
vi /etc/php/7.0/cli/php.ini
|
|
|
|
a2enmod php7.0
|
|
a2dismod mpm_event
|
|
a2enmod mpm_prefork
|
|
phpenmod mcrypt
|
|
|
|
### Configure Apache
|
|
|
|
vi /etc/apache2/sites-available/librenms.conf
|
|
|
|
Add the following config, edit `ServerName` as required:
|
|
|
|
```apache
|
|
<VirtualHost *:80>
|
|
DocumentRoot /opt/librenms/html/
|
|
ServerName librenms.example.com
|
|
|
|
AllowEncodedSlashes NoDecode
|
|
<Directory "/opt/librenms/html/">
|
|
Require all granted
|
|
AllowOverride All
|
|
Options FollowSymLinks MultiViews
|
|
</Directory>
|
|
</VirtualHost>
|
|
```
|
|
|
|
> NOTE: If this is the only site you are hosting on this server (it should be :)) then you will need to disable the default site.
|
|
`a2dissite 000-default`
|
|
|
|
a2ensite librenms.conf
|
|
a2enmod rewrite
|
|
systemctl restart apache2
|
|
|
|
#### Configure snmpd
|
|
|
|
cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf
|
|
vi /etc/snmp/snmpd.conf
|
|
|
|
Edit the text which says `RANDOMSTRINGGOESHERE` and set your own community string.
|
|
|
|
curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro
|
|
chmod +x /usr/bin/distro
|
|
systemctl restart snmpd
|
|
|
|
### Cron job
|
|
|
|
cp /opt/librenms/librenms.nonroot.cron /etc/cron.d/librenms
|
|
|
|
#### Copy logrotate config
|
|
|
|
LibreNMS keeps logs in `/opt/librenms/logs`. Over time these can become large and be rotated out. To rotate out the old logs you can use the provided logrotate config file:
|
|
|
|
cp /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms
|
|
|
|
### Set permissions
|
|
|
|
chown -R librenms:librenms /opt/librenms
|
|
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
|
|
setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
|
|
|
|
## Web installer ##
|
|
|
|
Now head to the web installer and follow the on-screen instructions.
|
|
|
|
http://librenms.example.com/install.php
|
|
|
|
The web installer might prompt you to create a `config.php` file in your librenms install location manually, copying the content displayed on-screen to the file. If you have to do this, please remember to set the permissions on config.php after you copied the on-screen contents to the file. Run:
|
|
|
|
chown librenms:librenms /opt/librenms/config.php
|
|
|
|
### Final steps
|
|
|
|
That's it! You now should be able to log in to http://librenms.example.com/. Please note that we have not covered HTTPS setup in this example, so your LibreNMS install is not secure by default. Please do not expose it to the public Internet unless you have configured HTTPS and taken appropriate web server hardening steps.
|
|
|
|
#### Add the first device
|
|
|
|
We now suggest that you add localhost as your first device from within the WebUI.
|
|
|
|
#### Troubleshooting
|
|
|
|
If you ever have issues with your install, run validate.php as root in the librenms directory:
|
|
|
|
cd /opt/librenms
|
|
./validate.php
|
|
|
|
