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{ "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(jiān)聽(tīng)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(wù)

[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(shù)據(jù)傳入。

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(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

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
