Create Installation-Ubuntu-1804-Nginx.md (#8630)
* Create Installation-Ubuntu-1804-Nginx.md A few tweaks are required to the Ubuntu 16.04 instructions to install on the newly released 18.04 version mostly relating to php being bumped to 7.2 from 7.0 and no mcrypt module for this php version in the distro repository. * Create Installation-Ubuntu-1804-Apache.md Used instructions from 1604 Apache as template and updated to work on Bionic (18.04). * Update Installation-Ubuntu-1804-Nginx.md Removed instructions for installing mcrypt module as I confirmed it works without it and it was mentioned it was no longer needed. * Update Installation-Ubuntu-1804-Apache.md The 1604 directions had a mixture of vi and vim for editing files. Since this is ubuntu and we want the instructions to be as easy as possible, I updated editor to be nano. I have no personal preference and can make it whatever we prefer, just figured it should be consistent between the two guides. * Update mkdocs.yml Added Ubuntu 18.04 instruction pages * Update Installation-Ubuntu-1804-Apache.md Corrected to libapache2-mod-php7.2 from libapache2-mod-php7.0 * Updated Ubuntu install docs * Added missing mbstring + curl packages

## 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
|
||||
|
||||
#### 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
|
||||
|
||||
