docker - 从 docker 容器启动 neo4j 显示 "Neo4j is not running"

Question

我一直在尝试在容器中使用使用 neo4j 社区并且遇到错误。我认为这可能更多是 docker 使用问题而不是 neo4j 使用问题。

我从 https://github.com/neo4j/docker-neo4j-publish 构建了一个容器镜像2.3.9、3.3.3、3.3.4 和 3.3.5(唯一的区别是更高版本中的一些新端口)。我什至从 dockerhub.com 拉了一个原生 3.3.3

mkdir /tmp/data
chmod 777 /tmp/data
docker run --detach=true --name=neo4j --publish=7474:7474 --publish=7687:7687 --publish=7473:7473 --volume=/tmp/data:/data neo4j:3.3.3
docker exec -it neo4j find / -name '*.log'

虽然它似乎正在使用

neo4j> CREATE (n);
0 rows available after 50 ms, consumed after another 0 ms
Added 1 nodes
neo4j> CREATE (m),(o);
0 rows available after 15 ms, consumed after another 0 ms
Added 2 nodes
neo4j> MATCH (n) RETURN n;
+----+
| n  |
+----+
| () |
| () |
| () |
+----+

3 rows available after 21 ms, consumed after another 8 ms

我实际上得到这样的错误:

docker exec -it neo4j neo4j status
Neo4j is not running

现在这个看起来我错误地试图在一个正在运行的实例上启动另一个 Neo4j 实例:

 docker exec -it neo4j neo4j console

有人对 Neo4j 的 docker 实现有经验吗？这是一个单线程问题，意味着我需要以不同于容器的方式调用 CLI 工具吗？

Answer 1

neo4j status仅当您使用 neo4j start 启动 neo4j 时，该命令才有效. Start 创建一个 neo4j.pid 文件，status 使用该文件查看 neo4j 是否正在运行。在 docker 下启动使用控制台选项而不是启动选项。这不会创建 PID 文件，因此状态不起作用。但这并不重要，因为 neo4j 几乎是唯一运行的进程；如果 neo4j 死亡，容器将退出。如果 docker ps -a表示容器已启动，然后 neo4j 已启动。
