docker设置了端口映射，不能访问

#docker ps 查看，所有端口都做了映射，

但是无法访问
原因： docker里面的host不能配置127.0.0.1 或者192.168.0.1 或则宿主机器将无法访问端口

修改配置文件—（涉及到的，需要外部访问的都需要修改）

[root@ubuntu-10 open-falcon]# vim transfer/config/cfg.json
{
    "debug": true,
    "minStep": 30,
    "http": {
        "enabled": true,
        "listen": "0.0.0.0:6060"
    },
    "rpc": {
        "enabled": true,
        "listen": "0.0.0.0:8433"  **#此处监听外面8433. 改成0.0.0.0**
    },
    "socket": {
        "enabled": true,
        "listen": "0.0.0.0:4444",
        "timeout": 3600
    },
    "judge": {
        "enabled": true,
        "batch": 200,
        "connTimeout": 1000,
        "callTimeout": 5000,
        "maxConns": 32,
        "maxIdle": 32,
        "replicas": 500,
        "cluster": {
            "judge-00" : "127.0.0.1:6080"
        }
    },
    "graph": {
        "enabled": true,
        "batch": 200,
        "connTimeout": 1000,
        "callTimeout": 5000,
        "maxConns": 32,
        "maxIdle": 32,
        "replicas": 500,
        "cluster": {
            "graph-00" : "127.0.0.1:6070"

        }
    },
    "tsdb": {
        "enabled": false,
        "batch": 200,
        "connTimeout": 1000,
        "callTimeout": 5000,
        "maxConns": 32,
        "maxIdle": 32,
        "retry": 3,
        "address": "127.0.0.1:8088"
    }

修改好之后重启 docker里的服务，
[root@ubuntu-10 open-falcon]# ./open-falcon restart transfer

再次查看日志，

查看端口的连接性

test@ubuntu-10:/tmp/bak$ telnet 10.0.10.103 8433
Trying 10.0.10.103...
Connected to 10.0.10.103.
Escape character is '^]'.      #这就是ok的

能连接成功，
