啟動的時候 報錯了 ./launcher start app

1b3dd113bfcce18cc29ce63265fcd1ab930400d838396ffea98e1723220c3133
Error response from daemon: Cannot start container 1b3dd113bfcce18cc29ce63265fcd1ab930400d838396ffea98e1723220c3133: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use

80端口不能 kill 掉呀 ，線上還跑著其他web 服務

root@iZ25pamnfsuZ:/var/discourse# docker images

docker run -d -p 8080:80 tutum/lamp

修改80端口 後如下

root@iZ25pamnfsuZ:/var/discourse# docker run -d -p 8080:80 local_discourse/app
f42e59fbb40384e971ade4ead24d93929f7df1fb8bcb74fb6d78ce3a17a52d65
root@iZ25pamnfsuZ:/var/discourse# ./launcher start app

starting up existing container
+ /usr/bin/docker start app
Error response from daemon: Cannot start container app: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use
Error: failed to start containers: [app]

執行後 還是 不對

Answer 1

Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use

沒看到麼？你查一下是什麼東西把80埠給佔用了，然後kill掉。

Answer 2

1. 埠被佔用
   換埠

範例:

docker run -d -p 8080:80 tutum/lamp
