Install or Uninstall mongot on Linux

Download the mongot tarball.

单击以下链接下载社区搜索 tarball。

(Optional). Verify the integrity of the tarball package.

See Verify Integrity of mongot Packages for more information.

Extract the mongot tarball.

运行以下命令以提取 tarball：

tar -zxvf mongot_community_0.53.0_linux_aarch64.tgz

tar -zxvf mongot_community_0.53.0_linux_x86_64.tgz

The tarball contains a sample configuration file, the mongot launcher script, and MongoDB Search and Vector Search license information.

Configure mongod to communicate with mongot.

如果您有要使用的现有副本集，请配置以下 mongod 参数来路由搜索和MongoDB Vector Search 查询并托管索引。

示例，您可以将以下行添加到 mongod 配置文件中，然后重新启动 mongod：

setParameter:
   searchIndexManagementHostAndPort: localhost:27028
   mongotHost: localhost:27028
   skipAuthenticationToSearchIndexManagementServer: false
   useGrpcForSearch: true

See MongoDB Server Parameters for a Self-Managed Deployment for more information on setting mongod parameters. For detailed information about search-specific setParameter options, see MongoDB Search Options.

If you want to deploy a new replica set with keyfile authentication, follow the steps in Deploy Self-Managed Replica Set With Keyfile Authentication.

Create a user for the mongot process on your MongoDB deployment.

mongot must be able to connect to your MongoDB deployment through a user with the searchCoordinator role.

1. 以管理员用户身份连接到 mongosh。

   mongosh --port 27017 -u <your_admin_username> -p <your_admin_password>

2. 连接到 admin 数据库。

   运行以下命令以连接到 admin数据库：

   use admin

3. 创建 mongot 用户。

   要创建具有 searchCoordinator角色的用户：

   • 将 <your-mongot-username> 替换为 mongot 用户的用户名

   • 将 <your-mongot-password> 替换为您在 passwordFile 中指定的密码

   • 运行命令

   db.createUser(
      {
         user: <mongot_username>,
         pwd: <mongot_password>,
         roles: [ "searchCoordinator"]
      }
   )

创建密码文件。

为 mongot 创建密码文件，以连接到 mongod。

示例，选择您的操作系统并将 <mongot_password> 替换为您的密码。然后运行以下命令，创建名为 passwordFile 的文件：

echo -n "mongotPassword" > passwordFile
chmod 400 passwordFile

echo|set /p="mongotPassword" > passwordFile

[System.IO.File]::WriteAllText("passwordFile", "mongotPassword")

Specify your mongot configuration options.

You can configure mongot with a YAML configuration file. Use the included sample configuration file named config.default.yml or a new configuration file to define the configuration. For more information on mongot configuration options, see mongot Options.

The tarball contains the following sample configuration file, config.default.yml, with the default mongot settings. You can modify the settings for your deployment:

syncSource:
   replicaSet:
      hostAndPort: "localhost:27017" # Replace with the mongod host and port.
      username: mongotUser # Replace with mongod username enabled with "searchCoordinator" role.
      passwordFile: "/etc/mongot/secrets/passwordFile" # Replace with path to password file for the above user.
      tls: false
storage:
   dataPath: "/var/lib/mongot"  # Replace with the path where you want mongot to store search data.
server:
grpc:
   address: "localhost:27028" # Replace with the address and port for mongot listen server
   tls:
      mode: "disabled"
metrics:
   enabled: true
   address: "localhost:9946"
healthCheck:
   address: "localhost:8080"
logging:
   verbosity: INFO

启动mongot进程。

运行随 Tarball 下载的 mongot 启动器脚本。该脚本位于 mongot-community 文件夹中。

更改为 mongot-community 文件夹：

cd <path-to-mongot>

要使用示例配置文件启动 mongot，请发出以下命令：

./mongot --config config.default.yml

Verify the health of the mongot process.

To verify, send a request by using a HTTP client or curl to the /health endpoint. For example, send a curl request similar to the following sample request:

curl localhost:8080/health

端点在响应中返回以下内容之一：

• SERVING, if the mongot process is running

  mongot might not serve queries as it doesn't check the status of the indexes, which must be in Ready state to serve queries.

• NOT_SERVING, if the mongot process isn't running

Drop the mongotUser user

要删除 mongotUser 用户，运行以下命令：

use admin
db.dropUser("mongotUser")

For details, see db.dropUser().

停止 mongot

要停止 mongot 二进制文件，请在运行该二进制文件的终端会话中使用 Ctrl + C。

删除所有配置文件

To remove the mongot and mongod configuration files, run the following commands as root or with sudo by using the full path to your configuration files:

sudo rm /path/to/config.default.yml
sudo rm /path/to/mongod.conf

删除密钥文件和密码文件

要删除密钥文件和密码文件，请使用密钥文件和密码文件的完整路径运行以下命令：

rm /path/to/keyfile
rm /path/to/passwordFile

Remove any logs and the log directory for mongot

要删除mongot 的日志和日志目录，请使用日志目录的完整路径运行以下命令：

rm -rf /path/to/mongot-logs

Remove the data directory for mongot

要删除存储 mongot 数据的数据目录，请使用 mongot数据目录的完整路径运行以下命令：

rm /path/to/mongot/data
