我已经在Linux CentOS服务器上安装了mongo-10gen mongo-10gen-server。
我按照链接中的步骤操作。
我已将/etc/mongod.conf 配置为 -
logpath=/var/log/mongo/mongod.log
port=27017
dbpath=/var/lib/mongo
我已经在iptables中为mongo设置了端口27017。为了启动 mongo，我使用了命令 -
service mongod start and
mongo
它开始得很好，但几天后我收到错误 -

当我执行命令时 -
service mongod status
它给出错误 -
mongod dead but subsys locked
请帮我解决mongod死了但子系统锁定和期刊可用空间不足的问题，终止
您可以将以下内容添加到运行mongod --config mongod.conf时提供的配置文件中
对于MongoDB 3.x（最新版本）
storage:
mmapv1:
smallFiles: true
对于版本 2.6+
storage:
smallFiles: true
对于版本 2.4 及更低
版本smallfiles = true
然后只需执行 mongod 来接受你的配置文件（这里它假设配置的位置是/etc/mongodb.conf）：
mongod -f /etc/mongodb.conf
小文件参数的文档：
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.
使用以下命令启动mongod实例
mongod --dbpath /data/db --smallfiles
我正在遵循官方指南 http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
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：

溶液：
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，问题得到了解决：

对于遇到此问题的任何人，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。蒙戈给了我一个连接失败的问题。我使用 kill 命令来杀死 mongod 进程，这反过来又给了我子系统问题。以下是对我有用的方法：
转到/var/lock/subsys并删除文件mongod
现在service mongod stop，然后service mongod start
现在启动了 mongo shell，一切似乎都运行良好。
first
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。只是系统空间不足。清除系统的缓存对我来说很有效，mongo 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，它创建了这个锁定文件并抛出此错误， 蒙戈德死了，但子系统被锁定了在此之后，我无法使用mongo shell。
如果有足够的磁盘空间。然后按照以下步骤操作，
1.须藤君神（如果您发现以下失败原因）
Failed to unlink socket file /tmp/mongodb-27017.sock Operation not permitted)
转到 /tmp/ 目录
删除 mongodb-27017.sock 文件
使用sudo服务重新启动mongod mongod
