开始使用新的graph.db文件夹。我使用嵌入式图形db,java和cypher查询来创建节点。它似乎成功地创建了节点。已经调试并检查了结果对象。
我现在想启动neo4j服务器来检查浏览器中的节点。但是,它给出了消息:
bash-4.2 $ ./neo4j-community-2.2.1/bin/neo4j start
警告:最多1024 允许打开文件,建议至少40 000。看看Neo4j 手册。启动Neo4j服务器...
警告:不更改用户进程 [2868] ...等待服务器准备好......无法启动内部 120秒Neo4j服务器可能无法启动,请检查 日志。
我检查了console.log和message.log。但没有错误。我不知道在日志文件中要读什么来放在这里进行诊断。请指教。
CONSOLE.LOG:

我还应该在哪里寻找错误?如何启动neo4j服务器?
编辑:
已检查messages.log。下面的文字。所以看起来它正在通过代码关闭:
