docker設置瞭端口映射,不能訪問的解決方案
#docker ps 查看, 所有端口都 做瞭映射

但是無法訪問
原因:
docker裡面的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" }
修改好之後重啟 docker裡的服務
[root@ubuntu-10 open-falcon]# ./open-falcon restart transfer
再次查看日志
test@ubuntu-10:/tmp/bak$ tail -40 /home/work/open-falcon/agent/logs/agent.log 2018/10/15 02:52:48 var.go:88: => <Total=1> <Endpoint:test-endpoint, Metric:test-metric-97, Type:GAUGE, Tags:idc=lgi-test,loc=beijing-test, Step:20, Time:1539597168, Value:33> 2018/10/15 02:52:48 var.go:95: <= <Total=1, Invalid:0, Latency=0ms, Message:ok> 2018/10/15 02:52:48 var.go:88: => <Total=1> <Endpoint:test-endpoint, Metric:test-metric-97, Type:GAUGE, Tags:idc=lgi-test,loc=beijing-test, Step:20, Time:1539597168, Value:33> 2018/10/15 02:52:48 var.go:95: <= <Total=1, Invalid:0, Latency=0ms, Message:ok> 2018/10/15 02:52:48 var.go:88: => <Total=1> <Endpoint:test-endpoint, Metric:test-metric-97, Type:GAUGE, Tags:idc=lgi-test,loc=beijing-test, Step:20, Time:1539597168, Value:33> 2018/10/15 02:52:48 var.go:95: <= <Total=1, Invalid:0, Latency=0ms, Message:ok> #連接成功,數據傳入。
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”則表示成功瞭
以上為個人經驗,希望能給大傢一個參考,也希望大傢多多支持WalkonNet。如有錯誤或未考慮完全的地方,望不吝賜教。
