尝试编写一个脚本来安装Mongo,如果它不存在,至少在Ubuntu、Red Hat Linux和Mac OSX上安装。
想法是这样的:
#!/bin/bash
if [$mongoDoesntExist]; then
if [ $myOS = "Ubuntu" ]; then
# install Mongo on Ubuntu
else if [ $myOS = "Red Hat Linux"]; then
# install Mongo on Red Hat Linux
else if [ $myOS =
> db.user.find()
terminate called after throwing an instance of 'mongo::UserException'
what(): non ascii character detected

我正在阿尔卑斯Linux上编译Mongo。
有人知道如何克服这个错误吗?

我正试图在我的mongodb docker容器中执行一个命令。在我的linux命令提示符下,这非常简单,并且在我这样做的时候也能正常工作
docker exec -it d886e775dfad mongo --eval 'rs.isMaster()'
上面的代码告诉我转到一个容器并执行以下命令
"mongo --eval 'rs.isMaster()' - This tells mongo to take rs.isMaster() as an input and execute it. This works and gives me the outp
我有一个存储大型数据集的MongoDB数据库。我试图将我的数据库导入到MATLAB中以执行数据可视化,但在这样做的过程中我收到了一些奇怪的错误,我无法对其进行调试。我让我的数据库在端口27017上的本地主机上使用mongod运行。我确实有数据库工具箱为MATLAB添加,以及MongoDB特定的。按照MATLAB文档的示例,我创建了变量:
server = "0.0.0.0" (I have also tried putting localhost here)
port = 27017
dbname = "NYPDData"
conn = mongo(server
