ipfs 状态查看，修改配置文件，修改API

1，ipfs 状态

• ipfs stats repo 仓库状态
• ipfs stats bw网络状态

$ ipfs stats repo
NumObjects: 145
RepoSize:   689856
StorageMax: 10000000000
RepoPath:   /Users/y50/.ipfs
Version:    fs-repo@7
$ ipfs stats bw
Bandwidth
TotalIn: 23 MB
TotalOut: 14 MB
RateIn: 3.4 kB/s
RateOut: 3.0 kB/s

• ipfs bootstrap信任引导节点

$ ipfs bootstrap list

• ipfs swarm peers连接节点

$ ipfs swarm peers

• ipfs dht findpeer查看其它节点的信息

$ ipfs dht findpeer QmQamgdAXCCf6xxHUMRZCgv8qJJdrtXWCzfxTL1JdNe3xh
/ip4/192.168.1.7/tcp/4001
/ip4/192.168.122.1/tcp/4001
/ip6/::1/tcp/4001
/ip6/240e:fa:c676:2b00:21c:42ff:fe25:db22/tcp/4001
/ip4/113.104.227.178/tcp/9407
/ip4/127.0.0.1/tcp/4001

2，修改配置文件

• ipfs config show显示配置信息
• "StorageMax": "10GB"存储空间

$ ipfs config show

• 修改配置，EDITOR设置编辑器

$ which vim
/usr/bin/vim
$ export EDITOR=/usr/bin/vim
$ ipfs config edit

• 或者添加到环境变量里

# vim .bashrc
export EDITOR=/usr/bin/vim

# source .bashrc
# echo $EDITOR
/usr/bin/vim

3，修改API

• API 查看

$ ipfs config Addresses.API
/ip4/127.0.0.1/tcp/5001

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

• Addresses.API 修改

$ ipfs config Addresses.API
/ip4/127.0.0.1/tcp/5001
[y50@192 ~]$ ipfs config Addresses.API /ip4/0.0.0.0/tcp/5001

• Gateway修改

$ ipfs config Addresses.Gateway
/ip4/127.0.0.1/tcp/8080
[y50@192 ~]$ ipfs config Addresses.Gateway /ip4/0.0.0.0/tcp/8080
[y50@192 ~]$ ipfs config Addresses.Gateway
/ip4/0.0.0.0/tcp/8080

4，配置CORS

• API.HTTPHeaders查看

$ ipfs config --json API.HTTPHeaders
{}

• API.HTTPHeaders修改配置

$ ipfs config show
$ ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST", "OPTIONS"]'
$ ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
$ ipfs config --json API.HTTPHeaders.Access-Control-Allow-Credentials '["true"]'
$ ipfs config show

$ ipfs config --json API.HTTPHeaders
{
  "Access-Control-Allow-Credentials": [
    "true"
  ],
  "Access-Control-Allow-Methods": [
    "PUT",
    "GET",
    "POST",
    "OPTIONS"
  ],
  "Access-Control-Allow-Origin": [
    "*"
  ]
}
