一时失言乱红尘 2022-05-25 05:12 103阅读 0赞

fabric-ca 有两个子项目：一个是fabric-ca-client,另一个是fabric-ca-server  
**启动一个fabric-ca-server**

fabric-ca-server start -b admin:admin //会在当前目录生成证书相关的信息
    [root@fabric-cli server01]# ls -l
    总用量 60
    -rw-r--r-- 1 root root   786 5月   8 15:52 ca-cert.pem
    -rw-r--r-- 1 root root 15875 5月   8 15:52 fabric-ca-server-config.yaml
    -rw-r--r-- 1 root root 40960 5月   8 16:21 fabric-ca-server.db
    drwxr-xr-x 3 root root    22 5月   8 15:52 msp

enroll 启动用户，要不数据库里面没有相关的证书  
enroll之前

enroll之后

用admin注册一个用户admin2

[root@fabric-cli client-01]# fabric-ca-client register --id.name admin2 --id.type user --id.affiliation org1.department1 --id.attrs 'hf.Revoker=true,foo=bar' -H $PWD/admin 
    2018/05/08 16:06:05 [INFO] Configuration file location: /root/client-01/admin/fabric-ca-client-config.yaml
