Installation of Nexus is to /opt/sonatype/nexus. Notably: /opt/sonatype/nexus/conf/nexus.properties is the properties file. Parameters (nexus-work and nexus-webapp-context-path) defined here are overridden in the JVM invocation. A persistent directory, /sonatype-work, is used for configuration, logs, and storage. This directory needs to be writeable by the Nexus process, which runs as UID 200.
