最近我通过阅读本页(
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/)安装了mongodb软件包.
我使用docker和ubuntu 14.04映像来部署我的服务器.
我使用docker和ubuntu 14.04映像来部署我的服务器.
问题始于首先运行mongod服务：
- # service mongod start
我得到以下内容：
- Rather than invoking init scripts through /etc/init.d,use the service(8)
- utility,e.g. service mongod restart
- Since the script you are attempting to invoke has been converted to an
- Upstart job,you may also use the stop(8) and then start(8) utilities,e.g. stop mongod ; start mongod. The restart(8) utility is also available.
我试过这个：
- # start mongod
但没有输出.
接下来我想查看日志,但没有日志！
- ls /var/log/mongodb -a #empty
好的,接下来我尝试启动mongo shell：
好吧,谷歌搜索后我检查(applaied)从Mongodb in linux server和https://wiki.archlinux.org/index.php/MongoDB(部分故障排除)的所有答案,但仍然没有得到任何结果.
mongo shell只有在我直接在后台运行mongod时才能工作：

这里发生了什么？我很困惑(
解决方法
Docker容器通常没有完整的init系统,并且与upstart的交互在docker容器中不起作用. (从理论上说这是可能的,但它会破坏轻量堆叠的目的)
这意味着你启动一个docker容器,它会运行一个命令“/usr/bin/mongod”
在docker容器中运行mongodb的示例：
https://docs.docker.com/samples/library/mongo/
此外,由于您使用交互式docker容器运行安装命令,因此只要考虑docker,shell解释器就是单个命令.进入交互式会话后,您可以在后台运行mongod(正如您所做的那样)并启动mongo客户端会话.
另一种方法是将这些说明作为Dockerfile的一部分运行.您可以参考mongodb example.
您可能还想考虑已经在docker hub中发布的一些官方mongo db映像：
