Neo4j企业3.0启动失败

Question

我已经在ubuntu14.04上安装了一个新版本的Neo4j 3.0企业。还安装了java 8..

重新启动服务器后，我看到neo4j正在进程中运行，但如果我运行#service neo4j status，则会得到neo4j is not running

neo4j似乎已经在运行，但不是从相同的init.d neo4j脚本中运行的。

当我运行#service neo4j start时

Starting Neo4j.
/usr/share/neo4j/bin/neo4j: line 149: /var/run/neo4j/neo4j.pid: No such file or directory

安装了Java版本：

java版本"1.8.0_91“Java(TM) SE运行时环境(build 1.8.0_91-b14) Java HotSpot(TM) 64位服务器VM (Build25.91-b14，混合模式)

有什么建议吗？我试着安装了两次，却遇到了同样的问题。

(请帮助:)

Answer 1

发现了问题..。neo4j安装过程没有手动为/var/run/ created中的pid创建目录，现在它运行良好。

Answer 2

检查是否使用jps或ps aux | grep java运行java进程。确保没有进程正在为给定的db位置运行。
