FreeBSD

This page describes the steps for installing and upgrading NXLog Agent on FreeBSD.

Installing NXLog Agent

NXLog Agent is available as a precompiled package for FreeBSD. Follow these steps to install NXLog Agent.

First, download the appropriate NXLog Agent install file from the NXLog website.

Log in to your account, then click My account at the top of the page.
Under the Downloads > NXLog Agent files tab, choose the nxlog-6.4.9634_fbsd_x86_64.tgz package.
Use SFTP or a similar secure method to transfer the archive to the target server.
Log in to the target server as the root user.
Optional: To change the NXLog Agent user and group for the installation, set the NXLOG_USER and NXLOG_GROUP environment variables. During installation, a new user and group will be created from these environment variables. They will be used for the User and Group directives in nxlog.conf, and to set ownership of the /opt/nxlog directory. Specifying an already existing user or group is not supported. The created user and group will be deleted when you uninstall NXLog Agent.
```
# setenv NXLOG_USER nxlog2
# setenv NXLOG_GROUP nxlog2
```
Install NXLog Agent with the pkg(7) utility.
```
# pkg add nxlog-6.4.9634_fbsd_x86_64.tgz

```
The installation path is /opt/nxlog. Configuration files are located in /opt/nxlog/etc. The rc init script is placed in /etc/rc.d/ on installation. An nxlog user account is created, and NXLog Agent will run under this user by default.
Edit the configuration file.
```
# vi /opt/nxlog/etc/nxlog.conf
```
See Log collection in the NXLog Platform User Guide for more information and configuration examples.
For more details about configuring NXLog Agent to collect logs on FreeBSD, see FreeBSD log sources.

Verify the configuration file syntax.

# /opt/nxlog/bin/nxlog -v
2017-03-17 08:05:06 INFO configuration OK

To enable NXLog Agent, add the line nxlog_enable="YES" to /etc/rc.conf. Then manage the NXLog Agent service with the service(8) utility.
```
# service nxlog start
# service nxlog status
nxlog is running as pid 83708.
# service nxlog stop
process 83708 stopped
```

Upgrading NXLog Agent

To upgrade NXLog Agent, first remove the old version and then install the new version. Make a backup of the configuration files before starting this process so you can use them with the new installation.

Remove the installed version of NXLog Agent with the pkg(7) utility.
