* Split install steps into git clone and composer install This gives the admin a little more knowledge about how to maintain the system, showing them composer_wrapper.php and su - librenms They will get errors if composer_wrapper doesn't work because of a proxy or no internet connection We lose stats on packagist.org (https://packagist.org/packages/librenms/librenms/stats) If we wanted to keep stats, we could use: ``` COMPOSER_ALLOW_SUPERUSER=1 composer create-project --no-dev --no-install --keep-vcs librenms/librenms librenms dev-master ``` not sure that is worth it. * fix composer_wrapper.php path

## Web Server ##
|
|
|
|
### Configure and Start PHP-FPM
|
|
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/7.2/fpm/php.ini
|
|
vi /etc/php/7.2/cli/php.ini
|
|
|
|
systemctl restart php7.2-fpm
|
|
|
|
#### Configure NGINX
|
|
|
|
vi /etc/nginx/conf.d/librenms.conf
|
|
|
|
Add the following config, edit `server_name` as required:
|
|
|
|
```nginx
|
|
server {
|
|
listen 80;
|
|
server_name librenms.example.com;
|
|
root /opt/librenms/html;
|
|
index index.php;
|
|
|
|
charset utf-8;
|
|
gzip on;
|
|
gzip_types text/css application/javascript text/javascript application/x-javascript image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
|
|
location / {
|
|
try_files $uri $uri/ /index.php?$query_string;
|
|
}
|
|
location /api/v0 {
|
|
try_files $uri $uri/ /api_v0.php?$query_string;
|
|
}
|
|
location ~ \.php {
|
|
include fastcgi.conf;
|
|
fastcgi_split_path_info ^(.+\.php)(/.+)$;
|
|
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
|
|
}
|
|
location ~ /\.ht {
|
|
deny all;
|
|
}
|
|
}
|
|
```
|
|
|
|
rm /etc/nginx/sites-enabled/default
|
|
systemctl restart nginx
|
|
|
|
### 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
|
|
|
|
> NOTE: Keep in mind that cron, by default, only uses a very limited set of environment variables. You may need to configure proxy variables for the cron invocation. Alternatively adding the proxy settings in config.php is possible too. The config.php file will be created in the upcoming steps. Review the following URL after you finished librenms install steps: https://docs.librenms.org/Support/Configuration/#proxy-support
|
|
|
|
#### 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
|
|
|
|

### Closing
|
|
|
|
We hope you enjoy using LibreNMS. If you do, it would be great if you would consider opting into the stats system we have, please see [this page](http://docs.librenms.org/General/Callback-Stats-and-Privacy/) on what it is and how to enable it.
