* Update Install-LibreNMS.md Composer complains that neither unzip nor 7z is installed so it would unzip using PHP which may or may not corrupt the results file. This has always worked fine for me but I guess it might be a better idea to use the "real" unzipper. ``` librenms@librenms1:~$ ./scripts/composer_wrapper.php install --no-dev Could not scan for classes inside "vendor/dapphp/radius" which does not appear to be a file nor a folder > LibreNMS\ComposerHelper::preInstall Installing dependencies from lock file Verifying lock file contents can be installed on current platform. Package operations: 118 installs, 0 updates, 0 removals As there is no 'unzip' nor '7z' command installed zip files are being unpacked using the PHP zip extension. This may cause invalid reports of corrupted archives. Besides, any UNIX permissions (e.g. executable) defined in the archives will be lost. Installing 'unzip' or '7z' (21.01+) may remediate them. ``` * Update Install-LibreNMS.md Sorted 'unzip' package alphabetically in Debian, Ubuntu and CentOS installation steps.

# Install LibreNMS
|
|
|
|
## Prepare Linux Server
|
|
|
|
You should have an installed Linux server running one of the supported OS.
|
|
Make sure you select your server's OS in the tabbed options below.
|
|
Choice of web server is your preference, NGINX is recommended.
|
|
|
|
Connect to the server command line and follow the instructions below.
|
|
!!! note
|
|
|
|
These instructions assume you are the **root** user.
|
|
If you are not, prepend `sudo` to the shell commands (the ones that aren't
|
|
at `mysql>` prompts) or temporarily become a user with root
|
|
privileges with `sudo -s` or `sudo -i`.
|
|
|
|
**Please note the minimum supported PHP version is @= php.version_min =@**
|
|

## Add librenms user
|
|
|
|
```
|
|
useradd librenms -d /opt/librenms -M -r -s "$(which bash)"
|
|
```
|
|
|
|
## Download LibreNMS
|
|
|
|
```
|
|
cd /opt
|
|
git clone https://github.com/librenms/librenms.git
|
|
```
|
|
|
|
## Set permissions
|
|
|
|
```
|
|
chown -R librenms:librenms /opt/librenms
|
|
chmod 771 /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/
|
|
```
|
|
|
|
## Install PHP dependencies
|
|
|
|
```
|
|
su - librenms
|
|
./scripts/composer_wrapper.php install --no-dev
|
|
exit
|
|
```
|
|
Sometimes when there is a proxy used to gain internet access, the above script may fail. The workaround is to install the `composer` package manually. For a global installation:
|
|
```
|
|
wget https://getcomposer.org/composer-stable.phar
|
|
mv composer-stable.phar /usr/bin/composer
|
|
chmod +x /usr/bin/composer
|
|
```
|
|
|
|
## Set timezone
|
|
|
|
See <https://php.net/manual/en/timezones.php> for a list of supported
|
|
timezones. Valid examples are: "America/New_York", "Australia/Brisbane", "Etc/UTC".
|
|
Ensure date.timezone is set in php.ini to your preferred time zone.
|
|
|
|
=== "Ubuntu 22.04"
|
|
```bash
|
|
vi /etc/php/8.1/fpm/php.ini
|
|
vi /etc/php/8.1/cli/php.ini
|
|
```
|
|
|
|
=== "Ubuntu 20.04"
|
|
```bash
|
|
vi /etc/php/8.1/fpm/php.ini
|
|
vi /etc/php/8.1/cli/php.ini
|
|
```
|
|

|
|
```
|
|
|
|

|
|
```bash
|
|
vi /etc/php/8.2/fpm/php.ini
|
|
vi /etc/php/8.2/cli/php.ini
|
|
```
|
|
|
|
Remember to set the system timezone as well.
|
|
|
|
```
|
|
timedatectl set-timezone Etc/UTC
|
|
```
|
|
|
|
|
|
## Configure MariaDB
|
|
|
|
=== "Ubuntu 22.04"
|
|
```
|
|
vi /etc/mysql/mariadb.conf.d/50-server.cnf
|
|
```
|
|
|
|
=== "Ubuntu 20.04"
|
|
```
|
|
vi /etc/mysql/mariadb.conf.d/50-server.cnf
|
|
```
|
|
|
|
=== "CentOS 8"
|
|
```
|
|
vi /etc/my.cnf.d/mariadb-server.cnf
|
|
```
|
|
|
|
=== "Debian 11"
|
|
```
|
|
vi /etc/mysql/mariadb.conf.d/50-server.cnf
|
|
```
|
|
|
|
Within the `[mysqld]` section add:
|
|
|
|
```
|
|
innodb_file_per_table=1
|
|
lower_case_table_names=0
|
|
```
|
|
|
|
Then restart MariaDB
|
|
|
|
```
|
|
systemctl enable mariadb
|
|
systemctl restart mariadb
|
|
```
|
|
Start MariaDB client
|
|
|
|
```
|
|
mysql -u root
|
|
```
|
|
|
|
> NOTE: Change the 'password' below to something secure.
|
|
|
|
```sql
|
|
CREATE DATABASE librenms CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
|
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'password';
|
|
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost';
|
|
exit
|
|
```
|
|
|
|
## Configure PHP-FPM
|
|
|
|
=== "Ubuntu 22.04"
|
|
```bash
|
|
cp /etc/php/8.1/fpm/pool.d/www.conf /etc/php/8.1/fpm/pool.d/librenms.conf
|
|
vi /etc/php/8.1/fpm/pool.d/librenms.conf
|
|
```
|
|
|
|
=== "Ubuntu 20.04"
|
|
```bash
|
|
cp /etc/php/8.1/fpm/pool.d/www.conf /etc/php/8.1/fpm/pool.d/librenms.conf
|
|
vi /etc/php/8.1/fpm/pool.d/librenms.conf
|
|
```
|
|
|
|
=== "CentOS 8"
|
|
```bash
|
|
cp /etc/php-fpm.d/www.conf /etc/php-fpm.d/librenms.conf
|
|
vi /etc/php-fpm.d/librenms.conf
|
|
```
|
|
|
|
=== "Debian 11"
|
|
```bash
|
|
cp /etc/php/8.2/fpm/pool.d/www.conf /etc/php/8.2/fpm/pool.d/librenms.conf
|
|
vi /etc/php/8.2/fpm/pool.d/librenms.conf
|
|
```
|
|
|
|
Change `[www]` to `[librenms]`:
|
|
```
|
|
[librenms]
|
|
```
|
|
|
|
Change `user` and `group` to "librenms":
|
|
```
|
|
user = librenms
|
|
group = librenms
|
|
```
|
|
|
|
Change `listen` to a unique path that must match your webserver's config (`fastcgi_pass` for NGINX and `SetHandler` for Apache) :
|
|
```
|
|
listen = /run/php-fpm-librenms.sock
|
|
```
|
|
|
|
If there are no other PHP web applications on this server, you may remove www.conf to save some resources.
|
|
Feel free to tune the performance settings in librenms.conf to meet your needs.

create this file anywhere, as it is a throw-away file. The last step
|
|
in this install procedure will install the module in the proper
|
|
location.
|
|
|
|
```
|
|
module http_fping 1.0;
|
|
|
|
require {
|
|
type httpd_t;
|
|
class capability net_raw;
|
|
class rawip_socket { getopt create setopt write read };
|
|
}
|
|
|
|
#============= httpd_t ==============
|
|
allow httpd_t self:capability net_raw;
|
|
allow httpd_t self:rawip_socket { getopt create setopt write read };
|
|
```
|
|
|
|
Then run these commands
|
|
|
|
```
|
|
checkmodule -M -m -o http_fping.mod http_fping.tt
|
|
semodule_package -o http_fping.pp -m http_fping.mod
|
|
semodule -i http_fping.pp
|
|
```

## Enable lnms command completion
|
|
|
|
This feature grants you the opportunity to use tab for completion on lnms commands as you would
|
|
for normal linux commands.
|
|
|
|
```
|
|
ln -s /opt/librenms/lnms /usr/bin/lnms
|
|
cp /opt/librenms/misc/lnms-completion.bash /etc/bash_completion.d/
|
|
```
|
|
|
|
## 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 enable snmpd
|
|
systemctl restart snmpd
|
|
```
|
|
|
|
## Cron job
|
|
|
|
```
|
|
cp /opt/librenms/dist/librenms.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:
|
|
> <@= config.site_url =@/Support/Configuration/#proxy-support>
|
|
|
|
## Enable the scheduler
|
|
|
|
```
|
|
cp /opt/librenms/dist/librenms-scheduler.service /opt/librenms/dist/librenms-scheduler.timer /etc/systemd/system/
|
|
|
|
systemctl enable librenms-scheduler.timer
|
|
systemctl start librenms-scheduler.timer
|
|
```
|
|
|
|
## 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
|
|
```
|
|
|
|
## Web installer
|
|
|
|
Now head to the web installer and follow the on-screen instructions.
|
|
|
|
<http://librenms.example.com/install>
|
|
|
|
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:
|
|
|
|
```
|
|
sudo su - librenms
|
|
./validate.php
|
|
```
|
|
|
|
There are various options for getting help listed on the LibreNMS web
|
|
site: <https://www.librenms.org/#support>
|
|
|
|
## What next?
|
|
|
|
Now that you've installed LibreNMS, we'd suggest that you have a read
|
|
of a few other docs to get you going:
|
|
|
|
- [Performance tuning](../Support/Performance.md)
|
|
- [Alerting](../Alerting/index.md)
