如何设置featureCompatibilityVersion而无需访问Ubuntu 16.10中的Mongo shell？

Question

我正在尝试在我的本地机器上安装MongoDB 3.2,运行Ubuntu 16.10.

在安装过程中,没有错误; 然后,当我跑mongod,我得到以下错误:

Cannot start mongod when the featureCompatibilityVersion is higher than 3.2. See http://dochub.mongodb.org/core/3.4-feature-compatibility.

Fatal Assertion 40352

但是,当我在MongoDB的文档中找到该链接时,它显示设置功能兼容性的唯一方法是通过mongoshell.然而,我甚至无法访问它,正如我之前提到的那样,并在下面的终端输出中显示.

我以前安装了MongoDB 3.4,但我需要3.2,因为这是与mLab兼容的最新版本,我将在转向生产时使用.

所以首先我尝试降级它,我遇到了同样的问题.然后我尝试完全卸载3.4(按照卸载说明)并安装3.2.然后我得到了同样的错误.

这是完整的终端输出:

***aborting after fassert() failure

也许在卸载过程中我还没有完全删除文件？我做了以下卸载(根据他们的安装指南):

sudo apt-get purge mongodb-org*

sudo rm -r /var/log/mongodb

sudo rm -r /var/lib/mongodb

但也许这并没有完全清除一切？

在任何方面,如何在不访问mongoshell的情况下设置功能兼容性？

谢谢.

PS我一直在遵循Ubuntu 16.04的说明,因为16.10还没有.这可能是问题的根源吗？

您正尝试删除文件,/var/lib/mongodb但根据您的日志文件中的数据文件/data/db.

尝试从中删除文件/data/db/以解决问题: sudo rm -rf /data/db*
