【问题描述】：
我在 ubuntu 14.04 上安装了新版 Neo4j 3.0 企业版。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，但如果我这样做 #service neo4j status 我会得到 neo4j is not running
neo4j 似乎已经在运行，但不是来自同一个 init.d neo4j 脚本。
当我运行#service neo4j start 时，我得到了
Starting Neo4j.
/usr/share/neo4j/bin/neo4j: line 149: /var/run/neo4j/neo4j.pid: No such file or directory
来自 neo4j 的日志：

尝试删除
/var/lib/neo4j/data/databases/graph.db/store_lock文件并重启neo4j。
