linux – MongoDB进程每天都在关闭.怎么在服务器上永远运行mongod？

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,我在没有问题的情况下将MongoDB 2.4.1安装到了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’的文件夹和’data / db’来做一些试验.

从控制台,我通过SSH协议连接到服务器,然后运行

./mongod --dbpath 'data/db'

它的工作原理.

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关闭,即我无法跨域查看我的数据,然后,我需要再次运行mongod.有：

./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？

我怎么能永远运行这个过程？

对不起我的英语不好.

编辑：添加上一个错误日志.我不明白.

最佳答案

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,那么您的主机必须解决这个问题.

另外,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"

表明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.
