我尝试在本地计算机上安装MongoDB 3.2,运行Ubuntu 16.10。
在安装过程中,没有错误;然后,当我运行mongod
时,我收到以下错误:
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,设置功能兼容性的唯一方法是通过mongo
shell。然而,正如我之前提到的那样,我甚至无法访问它,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:

也许在卸载过程中我还没有完全删除的文件?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mongo
shell的情况下设置功能兼容性?
谢谢。
P.S。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?
答案 0 :(得分:6)
您正尝试从/var/lib/mongodb
删除文件,但根据您的日志文件,数据文件位于/data/db
。
尝试从/data/db/
删除文件以解决问题:
sudo rm -rf /data/db*
