长安链使用技巧总结

长安链获取新增节点nodeId方式

节点id用于在新增节点时执行某些cmc命令时带入。节点id是通过证书目录下node/consensus1里边的tls证书。

[[email protected] cmc]# ./cmc cert nid --node-cert-path ./testdata/crypto-config/ljh-org2.qianjinlian.com/node/consensus1/consensus1.tls.crt
node id : Qmcgik9z8Hsbzn2UKetjfPur9t3U5ukdMMTHHLyb3ekTxx

长安链区块链浏览器的数据清理

首先删掉mysql容器

#查看mysql容器
[[email protected] _data]# docker ps -a|grep mysql
5ea89d5fd755        mysql:5.7                                                              "docker-entrypoint.s…"   7 minutes ago       Exited (0) 2 minutes ago                       chainmaker-explorer-cm_db-1
#查看mysql容器的挂载目录
[[email protected] _data]# docker inspect chainmaker-explorer-cm_db-1 | grep Mounts -A 20

                "/proc/scsi",
                "/sys/firmware"
            ],
            "ReadonlyPaths": [

        "Mounts": [

                "RW": true,
                "Propagation": ""
            }
        ],
        "Config": {
            "Hostname": "5ea89d5fd755",

删掉挂载目录/var/lib/docker/volumes/chainmaker-explorer_explorer_db_data/_data下的所有文件。然后重启长安链浏览器即可。
