Install MongoDB Enterprise on macOS在macOS上安装MongoDB企业版

Create the data directory.创建数据目录。

Before you start MongoDB for the first time, you must create the directory to which the mongod process will write data.在首次启动MongoDB之前，您必须创建mongod进程将写入数据的目录。

For example, to create the ~/data/db directory:

sudo mkdir -p ~/data/db

Create the log directory.创建日志目录。

You must also create the directory in which the mongod process will write its log file:您还必须创建mongod进程将在其中写入日志文件的目录：

For example, to create the ~/data/log/mongodb directory:例如，要创建~/data/log/mongodb目录：

sudo mkdir -p ~/data/log/mongodb

Set permissions for the data and log directories.设置数据和日志目录的权限。

Ensure that the user account running mongod has read and write permissions for these two directories. 确保运行mongod的用户帐户对这两个目录具有读写权限。If you are running mongod as your own user account, and you just created the two directories above, they should already accessible to your user. 如果你以自己的用户帐户运行mongod，并且你刚刚创建了上面的两个目录，那么用户应该已经可以访问它们了。Otherwise, you can use chown to set ownership, substituting the appropriate user:否则，您可以使用chown设置所有权，替换相应的用户：

sudo chown <user> ~/data/db
sudo chown <user> ~/data/log/mongodb

Run MongoDB.运行MongoDB。

To run MongoDB, run the mongod process at the system prompt, providing the two parameters dbpath and logpath from above, and the nohup command to run mongod in the background. 要运行MongoDB，请在系统提示符下运行mongod进程，提供上面的dbpath和logpath两个参数，并在后台运行nohup命令。Alternatively, you may choose to store the values for dbpath, logpath, and many other parameters in a configuration file.或者，您可以选择将dbpath、logpath和许多其他参数的值存储在配置文件中。

nohup mongod --dbpath ~/path/to/dbdir --logpath ~/path/to/mongodb.log >/dev/null &

mongod --config /usr/local/etc/mongod.conf

macOS may prevent mongod from running after installation. macOS可能会阻止mongod在安装后运行。If you receive a security error when starting mongod indicating that the developer could not be identified or verified, do the following to grant mongod access to run:如果在启动mongod时收到安全错误，表明无法识别或验证开发人员，请执行以下操作以授予mongod运行权限：

• Open System Preferences打开系统首选项
• Select the Security and Privacy pane.选择“安全和隐私”窗格。
• Under the General tab, click the button to the right of the message about mongod, labelled either Open Anyway or Allow Anyway depending on your version of macOS.在“常规”选项卡下，单击有关mongod的消息右侧的按钮，根据macOS版本，标记为“无论如何打开”或“无论如何允许”。

Verify that MongoDB has started successfully.验证MongoDB是否已成功启动。

Verify that MongoDB has started successfully:验证MongoDB是否已成功启动：

ps aux | grep -v grep | grep mongod

If you do not see a mongod process running, check the logfile for any error messages.如果您没有看到mongod进程正在运行，请检查日志文件中是否有任何错误消息。

Begin using MongoDB.开始使用MongoDB。

Start a mongosh session on the same host machine as the mongod. 在与mongod相同的主机上启动mongosh会话。You can run mongosh without any command-line options to connect to a mongod that is running on your localhost with the default port of 27017:您可以在没有任何命令行选项的情况下运行mongosh，以连接到在本地主机上运行的mongod，默认端口为27017：

mongosh

For more information on connecting using mongosh, such as to connect to a mongod instance running on a different host and/or port, see the mongosh documentation.有关使用mongosh连接的更多信息，例如连接到在不同主机和/或端口上运行的mongod实例，请参阅mongosh文档。

To help you start using MongoDB, MongoDB provides Getting Started Guides in various driver editions. See Getting Started with MongoDB for the available editions.为了帮助您开始使用MongoDB，MongoDB提供了各种驱动程序版本的入门指南。有关可用版本，请参阅MongoDB入门。
