mongod没有停止(docker debian:wheezy)

标签: mongodb docker

我有以下Dockerfile:

FROM debian:wheezy

RUN apt-get update

RUN apt-get install -y apt-utils

RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
RUN echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.2 main" | tee /etc/apt/sources.list.d/mongodb-org-3.2.list
RUN apt-get update
RUN apt-get install -y mongodb-org

然后我建立了图像:

docker build -t my/image .

并尝试启动和停止服务器:

$ docker run -it my/image
root@35ba8193f979:/# service mongod start
[ ok ] Starting database: mongod.
root@35ba8193f979:/# service mongod stop
[FAIL] Stopping database: mongod failed!

如你所见,mongod未能停止。我可以通过运行ps和grepping for mongod进程来验证这一点;它还在那里。

这是日志:

我已经用Google搜索了解决方案;我发现的大部分帖子都很旧,或者没有描述与我相同的问题。非常感谢任何帮助。

service mongod stop似乎存在问题,因为它在内部调用的命令类似于:

start-stop-daemon --stop --pidfile /var/run/mongod.pid --user mongodb --exec /usr/bin/mongod

start-stop-daemon命令以某种方式找不到可执行文件/usr/bin/mongod,因此无法停止该过程。您可以在/etc/init.d/mongod

中查看服务脚本

我发现工作的解决方案是直接从命令行调用它而不是--exec

start-stop-daemon --stop --pidfile /var/run/mongod.pid

这似乎能够正常停止服务。

我认为这个问题不仅限于MongoDB,因为我发现了多个关于服务无法停止的引用。
