我已经在 Linux CentOS 服务器上安装了mongo-10gen mongo-10gen- server。

我按照Link的步骤进行操作。

我已将/etc/mongod.conf配置为 -

logpath=/var/log/mongo/mongod.log
port=27017
dbpath=/var/lib/mongo

我在iptables中为 mongo 设置了端口 27017 。要启动 mongo，我使用了命令 -

service mongod start and
mongo

它开始很好，但几天后我收到错误 -

当我执行命令时 -

service mongod status

它给出了错误 -

mongod dead but subsys locked

请帮我解决mongod dead but subsys locked和Insufficient free space for journals, termination的问题

您可以将以下内容添加到运行时提供的配置文件中mongod --config mongod.conf

对于 MongoDB 3.x（最新版本）

storage:
   mmapv1:
      smallFiles: true

对于版本2.6+

storage:
   smallFiles: true

对于2.4及更低版本

smallfiles = true

然后只需执行 mongod 以接受您的配置文件（这里假设配置的位置是/etc/mongodb.conf）：

mongod -f /etc/mongodb.conf

smallfiles参数的文档：

Set to true to modify MongoDB to use a smaller default data file size. 
Specifically, smallfiles reduces the initial size for data files and
limits them to 512 megabytes. The smallfiles setting also reduces the
size of each journal files from 1 gigabyte to 128 megabytes.

我在http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/遵循官方指南

使用后

$sudo service mongod start

我通过查看此日志来验证 MongoDB 是否已成功启动：

/var/log/mongodb/mongod.log

这是我发现的问题：

2014-11-11T12:54:05.814-0500 [initandlisten] dbexit: really exiting now

解决方案：

在文件 /etc/mongod.conf 的末尾，我添加了这一行：

smallfiles = true

之后，我重新启动了 mongod 服务：

$sudo service mongod restart

然后当我去查看日志时，我意识到一切都很完美，并且问题得到了解决：

对于任何有此问题的人，尽管有足够的空间来创建日志文件。

我的问题：我有足够的空间来创建日志文件。Mongo 给了我一个连接失败的问题。我使用 kill 命令杀死了 mongod 进程，这反过来又给了我 subsys 问题。这对我有用：

转到/var/lock/subsys并删除文件mongod

时不时service mongod stop地service mongod start

现在启动了 mongo shell，一切似乎都运行良好。

第一的

cd /usr/local/src/mongo/bin/<br>

然后

./mongod --dbpath /usr/local/src/mongo/data/db/ --smallfiles

只是一个笔记，这对我有帮助。虽然没有与 mongo 相关的技术问题。只是系统空间不够。清除系统的缓存对我来说很有效，mongo 又恢复了平稳运行。

yum clean all

问题背景：我在不停止数据库服务的情况下将数据库服务器从 t2.micro 升级到更大的实例。作为回报，它创建了这个锁文件并抛出了这个错误， mongod dead but subsys locked 在此之后我无法使用 mongo shell。

如果你有足够的磁盘空间。然后按照这些步骤，

1. sudo mongod （如果您发现以下失败原因）

Failed to unlink socket file /tmp/mongodb-27017.sock Operation not permitted)

  1. 转到/tmp/目录

  2. 删除mongodb-27017.sock文件

  3. 使用sudo service mongod restart 重启 mongod
