The playbook

The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.

  1. 01recondistribution, version and package manager (apt or dnf)
  2. 02reconNeo4j already installed? which version?
  3. 03reconservice active?
  4. 04reconHTTP 7474 / Bolt 7687 ports free?
  5. 05reconJava 21 or 25 present? RAM (2 GB minimum)

What it verifies

Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

  1. 01Add the Neo4j repositoryVerified byls /etc/apt/sources.list.d/neo4j.list /etc/yum.repos.d/neo4j.repo 2>/dev/null | head -1
  2. 02Install Java 21 + Neo4jVerified byneo4j version
  3. 03Set the initial passwordVerified bytest -s /var/lib/neo4j/data/dbms/auth.ini && echo ok
  4. 04Enable and startVerified bycurl -s -o /dev/null -w '%{http_code}' --retry 10 --retry-connrefused http://127.0.0.1:7474/
  5. 05Check the Bolt connectionVerified byss -tlnH "sport = :7687"

Guardrails

Non-negotiable instructions the run must respect, whatever it finds on the server.

Never leave the default neo4j/neo4j password. If Neo4j is already installed, do not reinstall and do not touch auth.ini. Keep server.default_listen_address on localhost. Less than 2 GB of RAM → stop and report it.

How a recipe runs in Servor

Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.

  • 01Read-only reconnaissance before any change
  • 02Every command signed by your browser, approved by you
  • 03Each step verified before the run moves on, every run kept in the history
