工作井后neo4j 2启动失败

我的neo4j服务器工作正常，但我的服务器重新启动，neo4j没有启动

服务器：Ubuntu 13.10
jdk:oraclejdk

这是错误：

严重：无法在端口[7474]上启动Neo服务器

我以前遇到过这个问题。后来，我发现了一些需要确保正确处理的问题

如果处于嵌入式模式，请确保一次使用一个实例

正确注册关机挂钩

重新启动时，查看服务器是否仍在运行索引

从neo4j db文件夹中删除tm_tx_log.1文件，然后重新启动 现在，前3个不太可能导致您的问题，因此我捕获了抛出的异常，然后删除了tm_tx_log.1文件，然后初始化了服务。不是傻瓜式的，而是一种变通方法

     public class GraphDB {



        private static GraphDB graph = null;
        private static final String DB_PATH = "target/neo4j-db";
        private static GraphDatabaseService graphService = null;

        protected GraphDB() {
            try{
            graphService = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);
            registerShutdownHook(graphService);
            }catch(Exception e){
                File file = new File(DB_PATH+"/tm_tx_log.1");
                file.delete();
            }
        }

        public static GraphDB getInstance() {
            if (graph == null) {
                graph = new GraphDB();
            }
            return graph;
        }

        public GraphDatabaseService getGraphDbService() {
            return graphService;

        }

        public void clearDb() {
            try {
                // FileUtils.deleteRecursively();
                File files = new File(DB_PATH);
                for(File file : files.listFiles()){
                    FileDeleteStrategy.FORCE.delete(file);
                }
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }

        public void shutDown() {
            System.out.println();
            System.out.println("Shutting down database ...");
            graphService.shutdown();
        }

        private static void registerShutdownHook(final GraphDatabaseService graphDb) {
            Runtime.getRuntime().addShutdownHook(new Thread() {
                @Override
                public void run() {
                    graphDb.shutdown();
                }
            });
        }    
        }

在您的main部分中，调用handle时处理graphService为null的情况

public static void main(String[] args) {
        GraphDB graphDb = GraphDB.getInstance();
        if(graphDb == null){
            graphDb = GraphDB.getInstance();
        }
}

这是Neo4j 2.0.0最终版本吗？您能否与我们共享您的数据库以供检查？请给我发一封电子邮件到michael的neotechnology.com这个数据库是用来测试的，我从neo4j库中删除了graph.db文件夹，现在我认为这是一个由neo4j创建的干净的数据库startup@MichaelHunger我下载neo4j-community-1.8.3-unix.tar.gz并运行它，它运行得很好，wtf？看看这个答案：（为我工作）
