FreeBSD

This topic describes the steps to install and upgrade NXLog on FreeBSD.

Installing

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

First, download the appropriate NXLog install archive from the NXLog website.

Log in to your account, then click My account at the top of the page.
Under the Downloads > NXLog Enterprise Edition files tab, choose the nxlog-6.4.9638_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 user and group for the installation, set the NXLOG_USER and NXLOG_GROUP environment variables. During installation, a new user and a new group will be created based on these environment variables. They will be used for User and Group directives in nxlog.conf, and for the ownership of some directories under /opt/nxlog. Specifying an already existing user or group is not supported. The created user and group will be deleted on NXLog removal.
```
# setenv NXLOG_USER nxlog2
# setenv NXLOG_GROUP nxlog2
```
Install NXLog with the pkg(7) utility.
```
# pkg add nxlog-6.4.9638_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 will run under this user by default.
Edit the configuration file.
```
# vi /opt/nxlog/etc/nxlog.conf
```
General information about configuring NXLog can be found in Configuration. For more details about configuring NXLog to collect logs on BSD, see the FreeBSD summary.

Verify the configuration file syntax.

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

To enable NXLog, add the line nxlog_enable="YES" to /etc/rc.conf. Then manage the NXLog 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

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

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

# pkg delete nxlog

The uninstall script will remove NXLog along with the user, group, and files. The pkg utility will not remove new or modified files.

Manually remove the base directory. This will remove any new or modified files left behind by the previous step.
```
# rm -rf /opt/nxlog
```
