#docker ps 查看， 所有端口都 做了映射

但是無(wú)法訪問(wèn)
原因：
docker里面的host不能配置127.0.0.1 或者192.168.0.1 或則宿主機(jī)器將無(wú)法訪問(wèn)端口
修改配置文件—（涉及到的，需要外部訪問(wèn)的都需要修改）
[root@ubuntu-10 open-falcon]# vim transfer/config/cfg.json
{

"minStep": 30,
"http": {
"enabled": true,
"listen": "0.0.0.0:6060"
},
"rpc": {

},

}
修改好之后重啟 docker里的服務(wù)
[root@ubuntu-10 open-falcon]# ./open-falcon restart transfer
再次查看日志

查看端口的連接性
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 '^]'. #這就是ok的
好啦~ 可以連接成功。
補(bǔ)充：docker 鏡像啟動(dòng)成功但是無(wú)法訪問(wèn)
解決辦法：
vi /etc/sysctl.conf 或者
vi /usr/lib/sysctl.d/00-system.conf 添加如下代碼：
net.ipv4.ip_forward=1
重啟network服務(wù)
systemctl restart network 查看是否修改成功
sysctl net.ipv4.ip_forward 如果返回為“net.ipv4.ip_forward = 1”則表示成功了
