Deploy Self-Managed Sharded Cluster with Keyfile Authentication部署具有键文件身份验证的自我管理分片集群

Overview概述

Enforcing access control on a sharded cluster requires configuring:分片集群上实施访问控制需要配置:

For this tutorial, each member of the sharded cluster must use the same internal authentication mechanism and settings. 对于本教程,分片集群的每个成员都必须使用相同的内部身份验证机制和设置。This means enforcing internal authentication on each mongos and mongod in the cluster.这意味着对集群中的每个mongosmongod强制执行内部身份验证。

The following tutorial uses a keyfile to enable internal authentication.以下教程使用键文件启用内部身份验证。

Enforcing internal authentication also enforces user access control. 强制内部身份验证也会强制用户访问控制。To connect to the replica set, clients like mongosh need to use a user account. See Access Control.要连接到副本集,像mongosh这样的客户端需要使用用户帐户。请参阅访问控制

CloudManager and OpsManagerCloudManager和OpsManager

If you are using Cloud Manager or Ops Manager to manage your deployment, see the respective Cloud Manager manual or the Ops Manager manual to enforce authentication.如果您使用Cloud Manager或Ops Manager来管理部署,请参阅相应的Cloud Manager手册Ops Manager手册以强制执行身份验证。

Considerations注意事项

Important

To avoid configuration updates due to IP address changes, use DNS hostnames instead of IP addresses. It is particularly important to use a DNS hostname instead of an IP address when configuring replica set members or sharded cluster members.为避免因IP地址更改而进行配置更新,请使用DNS主机名而不是IP地址。在配置副本集成员或分片集群成员时,使用DNS主机名而不是IP地址尤为重要。

Use hostnames instead of IP addresses to configure clusters across a split network horizon. Starting in MongoDB 5.0, nodes that are only configured with an IP address fail startup validation and do not start.使用主机名而不是IP地址来配置跨拆分网络范围的集群。从MongoDB 5.0开始,仅配置了IP地址的节点无法启动验证,也无法启动。

IP BindingIP绑定

MongoDB binaries, mongod and mongos, bind to localhost by default.MongoDB二进制文件mongodmongos默认绑定到localhost

Keyfile Security键文件安全

Keyfiles are bare-minimum forms of security and are best suited for testing or development environments. For production environments we recommend using X.509 certificates.键文件是最低限度的安全形式,最适合测试或开发环境。对于生产环境,我们建议使用X.509证书

Access Control访问控制

This tutorial covers creating the minimum number of administrative users on the admin database only. For the user authentication, the tutorial uses the default SCRAM authentication mechanism. 本教程仅介绍在admin数据库上创建最小数量的管理用户。对于用户身份验证,本教程使用默认的SCRAM身份验证机制。Challenge-response security mechanisms are best suited for testing or development environments. 挑战响应安全机制最适合测试或开发环境。For production environments, we recommend using X.509 certificates or Self-Managed LDAP Proxy Authentication (available for MongoDB Enterprise only) or Kerberos Authentication on Self-Managed Deployments (available for MongoDB Enterprise only).对于生产环境,我们建议在自我管理部署上使用X.509证书自我管理LDAP代理身份验证(仅适用于MongoDB Enterprise)或Kerberos身份验证(仅供MongoDB Enterprise)。

For details on creating users for specific authentication mechanism, refer to the specific authentication mechanism pages.有关为特定身份验证机制创建用户的详细信息,请参阅特定的身份验证机制页面。

See ➤ Configure Role-Based Access Control for best practices for user creation and management.有关用户创建和管理的最佳实践,请参阅➤ 配置基于角色的访问控制

Users用户

In general, to create users for a sharded clusters, connect to the mongos and add the sharded cluster users.一般来说,要为分片集群创建用户,请连接到mongos并添加分片集群用户。

However, some maintenance operations require direct connections to specific shards in a sharded cluster. To perform these operations, you must connect directly to the shard and authenticate as a shard-local administrative user.然而,一些维护操作需要直接连接到分片集群中的特定分片。要执行这些操作,您必须直接连接到分片,并作为分片本地管理用户进行身份验证。

Shard-local users exist only in the specific shard and should only be used for shard-specific maintenance and configuration. You cannot connect to the mongos with shard-local users.分片本地用户只存在于特定的分片中,只应用于分片特定的维护和配置。您无法使用分片本地用户连接到mongos

This tutorial requires creating sharded cluster users, but includes optional steps for adding shard-local users.本教程要求创建分片集群用户,但包括添加分片本地用户的可选步骤。

See the Users in Self-Managed Deployments security documentation for more information.有关更多信息,请参阅自我管理部署中的用户安全文档。

Operating System操作系统

This tutorial uses the mongod and mongos programs. 本教程使用mongodmongos程序。Windows users should use the mongod.exe and mongos.exe programs instead.Windows用户应该使用mongod.exemongos.exe程序。

Before You Begin开始之前

Starting in MongoDB 8.0, you can use the directShardOperations role to perform maintenance operations that require you to execute commands directly against a shard.从MongoDB 8.0开始,您可以使用directShardOperations角色执行维护操作,这些操作要求您直接对分片执行命令。

Warning

Running commands using the directShardOperations role can cause your cluster to stop working correctly and may cause data corruption. 使用directShardOperations角色运行命令可能会导致集群停止正常工作,并可能导致数据损坏。Only use the directShardOperations role for maintenance purposes or under the guidance of MongoDB support. 仅将directShardOperations角色用于维护目的或在MongoDB支持的指导下使用。Once you are done performing maintenance operations, stop using the directShardOperations role.完成维护操作后,停止使用directShardOperations角色。

Deploy Sharded Cluster with Keyfile Access Control部署具有键文件访问控制的分片集群

The following procedures involve creating a new sharded cluster that consists of a mongos, the config servers, and two shards.以下过程涉及创建一个新的分片集群,该集群由一个mongos、配置服务器和两个分片组成。

Important

To avoid configuration updates due to IP address changes, use DNS hostnames instead of IP addresses. It is particularly important to use a DNS hostname instead of an IP address when configuring replica set members or sharded cluster members.为避免因IP地址更改而进行配置更新,请使用DNS主机名而不是IP地址。在配置副本集成员或分片集群成员时,使用DNS主机名而不是IP地址尤为重要。

Use hostnames instead of IP addresses to configure clusters across a split network horizon. Starting in MongoDB 5.0, nodes that are only configured with an IP address fail startup validation and do not start.使用主机名而不是IP地址来配置跨拆分网络范围的集群。从MongoDB 5.0开始,仅配置了IP地址的节点无法启动验证,也无法启动。

Create the Keyfile创建键文件

With keyfile authentication, each mongod or mongos instances in the sharded cluster uses the contents of the keyfile as the shared password for authenticating other members in the deployment. Only mongod or mongos instances with the correct keyfile can join the sharded cluster.通过键文件身份验证,分片集群中的每个mongodmongos实例都使用键文件的内容作为共享密码,用于对部署中的其他成员进行身份验证。只有具有正确键文件的mongodmongos实例才能加入分片集群。

Note

Keyfiles for internal membership authentication用于内部成员身份验证的键文件 use YAML format to allow for multiple keys in a keyfile. The YAML format accepts either:使用YAML格式允许键文件中有多个键。YAML格式接受以下任一格式:

  • A single key string (same as in earlier versions)单个键字符串(与早期版本相同)
  • A sequence of key strings一串键串

The YAML format is compatible with the existing single-key keyfiles that use the text file format.YAML格式与使用文本文件格式的现有单键键文件兼容。

A key's length must be between 6 and 1024 characters and may only contain characters in the base64 set. All members of the sharded cluster must share at least one common key.键的长度必须在6到1024个字符之间,并且只能包含base64集合中的字符。分片集群的所有成员必须至少共享一个公共键。

Note

On UNIX systems, the keyfile must not have group or world permissions. On Windows systems, keyfile permissions are not checked.在UNIX系统上,键文件不得具有组或世界权限。在Windows系统上,不检查键文件权限。

You can generate a keyfile using any method you choose. For example, the following operation uses openssl to generate a complex pseudo-random 1024 character string to use as a shared password. It then uses chmod to change file permissions to provide read permissions for the file owner only:您可以使用您选择的任何方法生成键文件。例如,以下操作使用openssl生成一个复杂的伪随机1024字符串,用作共享密码。然后,它使用chmod更改文件权限,仅为文件所有者提供读取权限:

openssl rand -base64 756 > <path-to-keyfile>
chmod 400 <path-to-keyfile>

See Keyfiles for additional details and requirements for using keyfiles.有关使用键文件的其他详细信息和要求,请参阅键文件

Distribute the Keyfile分发键文件

Copy the keyfile to each server hosting the sharded cluster members. 将键文件复制到托管分片集群成员的每个服务器。Ensure that the user running the mongod or mongos instances is the owner of the file and can access the keyfile.确保运行mongodmongos实例的用户是文件的所有者,并且可以访问键文件。

Avoid storing the keyfile on storage mediums that can be easily disconnected from the hardware hosting the mongod or mongos instances, such as a USB drive or a network attached storage device.避免将键文件存储在容易与托管mongodmongos实例的硬件断开连接的存储介质上,例如USB驱动器或网络连接的存储设备。

Create the Config Server Replica Set创建配置服务器副本集

The following steps deploys a config server replica set.以下步骤部署配置服务器副本集。

For a production deployment, deploys a config server replica set with at least three members. For testing purposes, you can create a single-member replica set.对于生产部署,部署一个至少有三个成员的配置服务器副本集。出于测试目的,您可以创建单个成员副本集。

1

Start each mongod in the config server replica set. Include the keyFile setting. 启动配置服务器副本集中的每个mongod。包括keyFile设置。The keyFile setting enforces both Self-Managed Internal/Membership Authentication and Role-Based Access Control in Self-Managed Deployments.keyFile设置在自我管理部署中强制执行自我管理内部/成员身份验证基于角色的访问控制

You can specify the mongod settings either via a configuration file or the command line.您可以通过配置文件或命令行指定mongod设置。

Configuration File配置文件

If using a configuration file, set security.keyFile to the keyfile's path, sharding.clusterRole to configsvr, and replication.replSetName to the desired name of the config server replica set.如果使用配置文件,请将security.keyFile设置为键文件的路径,将sharding.clusterRole设置为configsvr,并将replication.replSetName设置为配置服务器副本集的所需名称。

security:
keyFile: <path-to-keyfile>
sharding:
clusterRole: configsvr
replication:
replSetName: <setname>

Include additional options as required for your configuration. For instance, if you wish remote clients to connect to your deployment or your deployment members are run on different hosts, specify the net.bindIp setting.根据配置要求,包括其他选项。例如,如果您希望远程客户端连接到部署,或者部署成员在不同的主机上运行,请指定net.bindIp设置。

Start the mongod specifying the --config option and the path to the configuration file.启动mongod,指定--config选项和配置文件的路径。

mongod --config <path-to-config-file>

Command Line

If using the command line parameters, start the mongod with the --keyFile, --configsvr, and --replSet parameters.如果使用命令行参数,请使用--keyFile--configsvr--replSet参数启动mongod

mongod --keyFile <path-to-keyfile> --configsvr --replSet <setname> --dbpath <path>

Include additional options as required for your configuration. For instance, if you wish remote clients to connect to your deployment or your deployment members are run on different hosts, specify the --bind_ip.根据配置要求,包括其他选项。例如,如果您希望远程客户端连接到部署,或者部署成员在不同的主机上运行,请指定--bind_ip

2

Connect to a member of the replica set over the localhost interface.通过localhost接口连接到副本集的成员。

Connect mongosh to one of the mongod instances over the localhost interface. 通过localhost接口mongosh连接到mongod实例之一。You must run mongosh on the same physical machine as the mongod instance.您必须在与mongod实例相同的物理机器上运行mongosh

The localhost interface is only available since no users have been created for the deployment. The localhost interface closes after the creation of the first user.由于没有为部署创建用户,因此只能使用localhost接口。创建第一个用户后,localhost接口关闭。

3

The rs.initiate() method initiates the replica set and can take an optional replica set configuration document. rs.initiate()方法启动副本集,并可以获取可选的副本集配置文档In the replica set configuration document, include:副本集配置文档中,包括:

  • The _id. _idThe _id must match the --replSet parameter passed to the mongod.必须与传递给mongod--replSet参数匹配。

]
}
)

Once the config server replica set (CSRS) is initiated and up, proceed to creating the shard replica sets.启动并启动配置服务器副本集(CSRS)后,继续创建分片副本集。

Create the Shard Replica Sets创建分片副本集

For a production deployment, use a replica set with at least three members. For testing purposes, you can create a single-member replica set.对于生产部署,使用至少有三个成员的副本集。出于测试目的,您可以创建单个成员副本集。

These steps include optional procedures for adding shard-local users. Executing them now ensures that there are users available for each shard to perform shard-level maintenance.这些步骤包括添加分片本地用户的可选过程。现在执行它们可以确保每个分片都有用户可以执行分片级维护。

1

Start each member of the replica set with access control enabled.在启用访问控制的情况下启动副本集的每个成员。

Running a mongod with the keyFile parameter enforces both Self-Managed Internal/Membership Authentication and Role-Based Access Control in Self-Managed Deployments.使用keyFile参数运行mongod会在自我管理部署中强制执行自我管理内部/成员身份验证基于角色的访问控制

Start each mongod in the replica set using either a configuration file or the command line.使用配置文件或命令行启动副本集中的每个mongod

Configuration File配置文件

If using a configuration file, set the security.keyFile option to the keyfile's path, the replication.replSetName to the desired name of the replica set, and the sharding.clusterRole option to shardsvr.如果使用配置文件,请将security.keyFile选项设置为键文件的路径,将replication.replSetName设置为副本集的所需名称,将sharding.clusterRole选项设置为shardsvr

security:
keyFile: <path-to-keyfile>
sharding:
clusterRole: shardsvr

2

Connect to a member of the replica set over the localhost interface.通过localhost接口连接到副本集的成员。

Connect mongosh to one of the mongod instances over the localhost interface. 通过localhost接口mongosh连接到mongod实例之一。You must run mongosh on the same physical machine as the mongod instance.您必须在与mongod实例相同的物理机器上运行mongosh

The localhost interface is only available since no users have been created for the deployment. 由于没有为部署创建用户,因此只能使用localhost接口The localhost interface closes after the creation of the first user.创建第一个用户后,localhost接口关闭。

3

Initiate the replica set.启动副本集。

From mongosh, run the rs.initiate() method.mongosh运行rs.initiate()方法。

rs.initiate() can take an optional replica set configuration document. 可以采用可选的副本集配置文档In the replica set configuration document, include:副本集配置文档中,包括:

  • The _id field set to the replica set name specified in either the replication.replSetName or the --replSet option._id字段设置为replication.replSetName--replSet选项中指定的副本集名称。
  • The members array with a document per each member of the replica set.members数组,每个副本集的成员都有一个文档。

The following example initates a three member replica set.以下示例初始化一个由三个成员组成的副本集。

rs.initiate(
{
_id : "myReplSet",
members: [
{ _id : 0, host : "s1-mongo1.example.net:27018" },
{ _id : 1, host : "s1-mongo2.example.net:27018" },
{ _id : 2, host : "s1-mongo3.example.net:27018" }
]
}
)

rs.initiate() triggers an election and elects one of the members to be the primary.触发选举,并选举其中一名成员为primary

Connect to the primary before continuing. Use rs.status() to locate the primary member.请先连接到主服务器,然后再继续。使用rs.status()查找主要成员。

4

Create the shard-local user administrator (optional).创建分片本地用户管理员(可选)。

Important

After you create the first user, the localhost exception is no longer available.创建第一个用户后,localhost异常不再可用。

The first user must have privileges to create other users, such as a user with the userAdminAnyDatabase. 第一个用户必须具有创建其他用户的权限,例如具有userAdminAnyDatabase的用户。This ensures that you can create additional users after the Localhost Exception in Self-Managed Deployments closes.这可确保您可以在自我管理部署中的Localhost异常关闭后创建其他用户。

If at least one user does not have privileges to create users, once the localhost exception closes you may be unable to create or modify users with new privileges, and therefore unable to access necessary operations.

如果至少有一个用户没有创建用户的权限,一旦localhost异常关闭,您可能无法创建或修改具有新权限的用户,因此无法访问必要的操作。

Add a user using the db.createUser() method. 使用db.createUser()方法添加用户。The user should have at minimum the userAdminAnyDatabase role on the admin database.用户在admin数据库上至少应具有userAdminAnyDatabase角色。

You must be connected to the primary to create users.您必须连接到primary才能创建用户。

The following example creates the user fred with the userAdminAnyDatabase role on the admin database.以下示例在admin数据库上创建了具有userAdminAnyDatabase角色的用户fred

Important

Passwords should be random, long, and complex to ensure system security and to prevent or delay malicious access.密码应该是随机的、长的和复杂的,以确保系统安全,防止或延迟恶意访问。

Tip

You can use the passwordPrompt() method in conjunction with various user authentication management methods and commands to prompt for the password instead of specifying the password directly in the method or command call. 您可以将passwordPrompt()方法与各种用户身份验证管理方法和命令结合使用,以提示输入密码,而不是直接在方法或命令调用中指定密码。However, you can still specify the password directly as you would with earlier versions of the mongo shell.但是,您仍然可以像使用早期版本的mongo shell一样直接指定密码。

admin = db.getSiblingDB("admin")
admin.createUser(
{
user: "fred",
pwd: passwordPrompt(), // or cleartext password
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)

Enter the password when prompted. 出现提示时输入密码。See Database User Roles for a full list of built-in roles related to database administration operations.有关与数据库管理操作相关的内置角色的完整列表,请参阅数据库用户角色

To create additional users, you must authenticate as a user with userAdminAnyDatabase or userAdmin roles.要创建其他用户,您必须以userAdminAnyDatabaseuserAdmin角色的用户身份进行身份验证。

Add Shards to the Cluster将分片添加到集群

To proceed, you must be connected to the mongos and authenticated as the cluster administrator user for the sharded cluster.要继续,您必须连接到mongos,并作为分片集群的集群管理员用户进行身份验证。

Note

This is the cluster administrator for the sharded cluster and not the shard-local cluster administrator.这是分片集群的集群管理员,而不是分片本地集群管理员。

To add each shard to the cluster, use the sh.addShard() method. 要将每个分片添加到集群中,请使用sh.addShard()方法。If the shard is a replica set, specify the name of the replica set and specify a member of the set. In production deployments, all shards should be replica sets.如果分片是副本集,请指定副本集的名称并指定该集的一个成员。在生产部署中,所有分片都应该是副本集。

The following operation adds a single shard replica set to the cluster:以下操作将单个分片副本集添加到集群中:

sh.addShard( "<replSetName>/s1-mongo1.example.net:27017")

The following operation is an example of adding a standalone mongod shard to the cluster:以下操作是向集群添加独立mongod分片的示例:

sh.addShard( "s1-mongo1.example.net:27017")

Repeat these steps until the cluster includes all shards. At this point, the sharded cluster enforces access control for the cluster as well as for internal communications between each sharded cluster component.重复这些步骤,直到集群包含所有分片。此时,分片集群对集群以及每个分片集群组件之间的内部通信实施访问控制。

Shard a Collection分片集合

To proceed, you must be connected to the mongos and authenticated as the cluster administrator user for the sharded cluster.要继续,您必须连接到mongos,并作为分片集群的集群管理员用户进行身份验证。

Note

This is the cluster administrator for the sharded cluster and not the shard-local cluster administrator.这是分片集群的集群管理员,而不是分片本地集群管理员。

To shard a collection, use the sh.shardCollection() method. You must specify the full namespace of the collection and a document containing the shard key.要对集合进行分片,请使用sh.shardCollection()方法。您必须指定集合的完整命名空间和包含分片键的文档。

Your selection of shard key affects the efficiency of sharding, as well as your ability to take advantage of certain sharding features such as zones. 您对分片键的选择会影响分片的效率,以及您利用某些分片功能(如区域)的能力。See the selection considerations listed in the Choose a Shard Key.请参阅选择分片键中列出的选择注意事项。

If the collection already contains data, you must create an index on the shard key using the db.collection.createIndex() method before using shardCollection().如果集合已经包含数据,则必须在使用shardCollection()之前使用db.collection.createIndex()方法在分片键上创建索引。

If the collection is empty, MongoDB creates the index as part of sh.shardCollection().如果集合为空,MongoDB将创建索引作为sh.shardCollection()的一部分。

The following is an example of the sh.shardCollection() method:以下是sh.shardCollection()方法的示例:

sh.shardCollection("<database>.<collection>", { <key> : <direction> } )
