如何在一台机器上运行多个IPFS节点? [英] How to run several IPFS nodes on a single machine?

问题描述

为了进行测试，我希望能够在一台计算机上运行多个IPFS节点.

For testing, I want to be able to run several IPFS nodes on a single machine.

这是方案: 我在自行创建之后，在IPFS核心库的顶部构建小型服务. IPFS服务指南.当我尝试将客户端和服务器放在同一台计算机上时(请注意，它们中的每个都将创建自己的IPFS节点)，我将得到以下信息:

This is the scenario: I am building small services on top of IPFS core library, following the Making your own IPFS service guide. When I try to put client and server on the same machine (note that each of them will create their own IPFS node), I will get the following:

panic: cannot acquire lock: Lock FcntlFlock of /Users/long/.ipfs/repo.lock failed: resource temporarily unavailable

推荐答案

通常，从IPFS开始时，将使用ipfs init，这将创建一个新节点.为该特定节点存储的默认数据和配置位于~/.ipfs.这是创建新节点并对其进行配置的方法，以便它可以在默认节点之外运行.

Usually, when you start with IPFS, you will use ipfs init, which will create a new node. The default data and config stored for that particular node are located at ~/.ipfs. Here is how you can create a new node and config it so it can run besides your default node.

对于新节点，您必须再次使用ipfs init.例如，使用以下内容:

For a new node you have to use ipfs init again. Use for instance the following:

IPFS_PATH=~/.ipfs2 ipfs init

这将在〜/.ipfs2(不使用默认路径)处创建一个新节点.

This will create a new node at ~/.ipfs2 (not using the default path).

由于两个节点现在都绑定到相同的端口，因此您需要更改端口配置，以便两个节点可以并行运行.为此，打开〜/.ipfs2/config and find Addresses`:

As both of your nodes now bind to the same ports, you need to change the port configuration, so both nodes can run side by side. For this, open ~/.ipfs2/configand findAddresses`:

"Addresses": {
    "API": "/ip4/127.0.0.1/tcp/5001",
    "Gateway": "/ip4/127.0.0.1/tcp/8080",
    "Swarm": [
        "/ip4/0.0.0.0/tcp/4001",
        "/ip6/::/tcp/4001"
    ]
}

例如，以下内容:

"Addresses": {
    "API": "/ip4/127.0.0.1/tcp/5002",
    "Gateway": "/ip4/127.0.0.1/tcp/8081",
    "Swarm": [
        "/ip4/0.0.0.0/tcp/4002",
        "/ip6/::/tcp/4002"
    ]
}

这样，您应该能够在单个计算机上同时运行节点.ipfs和.ipfs2.

With this, you should be able to run both node .ipfs and .ipfs2 on a single machine.

注意:

1. 每当使用.ipfs2时，都需要设置环境变量IPFS_PATH=~/.ipfs2
2. 在您的示例中，您需要将客户端或服务器节点从〜/.ipfs更改为〜/.ipfs2
3. 您还可以使用IPFS_PATH =〜/.ipfs2 ipfs守护程序&
在第二个节点上启动守护程序.

1. Whenever you use .ipfs2, you need to set the env variable IPFS_PATH=~/.ipfs2
2. In your example you need to change either your client or server node from ~/.ipfs to ~/.ipfs2
3. you can also start the daemon on the second node using IPFS_PATH=~/.ipfs2 ipfs daemon &
