docker設置了端口映射,不能訪問的解決方案
#docker ps 查看， 所有端口都 做了映射

但是無法訪問
原因：docker里面的host不能配置127.0.0.1 或者192.168.0.1 或則宿主機器將無法訪問端口
修改配置文件—（涉及到的，需要外部訪問的都需要修改）
[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' **#此處監聽外面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' }
修改好之后重啟 docker里的服務
[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 8433Trying 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。
補充：docker 鏡像啟動成功但是無法訪問
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
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
以上為個人經驗，希望能給大家一個參考，也希望大家多多支持好吧啦網。如有錯誤或未考慮完全的地方，望不吝賜教。
