Question

我是MongoDB的初学者，我在服务器中执行此操作时遇到问题。

我的项目托管在hostmonster.com的服务器上，但他们不支持MongoDB数据库，尽管他们说我可以根据自己的责任安装它。

然后，我将MongoDB 2.4.1没有问题安装到Linux 64之后，在MongoDB bin文件夹中（使用：mongo，mongod，mongodump ...）我创建了一个名为'data'和'data / db'的文件夹做一些测试。

从控制台，我通过SSH协议连接到服务器，然后运行

./mongod --dbpath 'data/db'

它有效。

但是，我需要它永远自动运行。

我按照Mongodb can't start的步骤运行下一行：

./mongod --fork --dbpath 'data/db' --smallfiles --logpath 'data/mongodb.log' --logappend

它也有效，它开始了这个过程，我关闭了控制台，这个过程继续运行，我可以在我的域中查看我的数据。

问题是该过程需要一天时间才能完成，即我无法跨域查看我的数据，然后，我需要再次运行mongod。用：

./mongod --fork --dbpath 'data/db' --smallfiles --logpath 'data/mongodb.log' --logappend

我不想每天都这样做，我的问题是：

可能是什么问题？为什么mongod进程每天都会死？

我该怎样才能永远运行这个过程？

抱歉我的英文。

编辑：添加上一个错误日志。我不明白。

Answer 1

你的答案在这里：

Fri Apr 12 04:43:54.002 got signal 15 (Terminated), will terminate after current cmd ends
Fri Apr 12 04:43:54.151 [interruptThread] now exiting

您的进程正在接收信号15，这是默认的终止信号。它们的系统可能会自动杀死长时间运行的进程或类似的东西。如果确实发生了这种情况，那么你的主人必须解决这个问题。

此外，这些错误：

Fri Apr 12 04:43:54.280 [interruptThread] error removing journal files 
boost::filesystem::directory_iterator::construct: No such file or directory: "/home2/anuncio3/bin/mongodb-linux-x86_64-2.4.1/bin/data/db/journal"
Fri Apr 12 04:43:54.280 [interruptThread] error couldn't remove journal file during shutdown boost::filesystem::directory_iterator::construct: No such file or directory: "/home2/anuncio3/bin/mongodb-linux-x86_64-2.4.1/bin/data/db/journal"

表示安装的数据目录有问题。日志文件要么不存在要么丢失;如果系统上的某个进程正在尝试清理，那么如果某些东西正在查找你的日志文件，那就不会让我感到惊讶。

Answer 2

我知道这是一个老问题，但我的经验可能对其他评论者有所帮助。基于我的测试，他们只允许你在杀死它之前运行一个程序5分钟（有时超过这个），所以除非你有一个专用的IP，否则安装MongoDB是没用的。

MongoDB进程每天都在关闭。怎么在服务器上永远运行mongod？
