首先，查找原因

1.先看srs服务在哪

find / -type f -name srs 2>/dev/null

运行结果：

/var/lib/docker/overlay2/5347867cc0ffed43f1ae24eba609637bfa3cc7cf5f8c660976d2286fa6a88d2b/diff/usr/local/srs/objs/srs
/var/lib/docker/overlay2/5347867cc0ffed43f1ae24eba609637bfa3cc7cf5f8c660976d2286fa6a88d2b/diff/usr/local/srs/etc/init.d/srs
/var/lib/docker/overlay2/1055a7db13201f6d360446bb7e82cd1af5149547b96d906430ac5780bfb12b8b/diff/usr/local/srs/objs/srs
/var/lib/docker/overlay2/1055a7db13201f6d360446bb7e82cd1af5149547b96d906430ac5780bfb12b8b/diff/usr/local/srs/etc/init.d/srs

2.查看所有docker应用

docker ps -a

运行结果：

CONTAINER ID   IMAGE                                                        COMMAND                  CREATED         STATUS                     PORTS     NAMES
f26ee488e3d4   registry.cn-hangzhou.aliyuncs.com/ossrs/srs-stack:v5.12.17   "./bootstrap"            7 minutes ago   Created                              srs-stack
fc4fa444888d   tiangolo/nginx-rtmp                                          "nginx -g 'daemon of…"   2 hours ago     Exited (0) 7 minutes ago             dk_rtmp-nginx-rtmp-1

找打了name为srs-stack的应用

3.在docker里面运行srs

docker start srs-stack

运行结果：

Error response from daemon: driver failed programming external connectivity on endpoint srs-stack (e14ce5129c6c3068f14bbbb406cb3688bc8232238e3dc290d3650ad114b69252): Error starting userland proxy: listen tcp4 0.0.0.0:8080: bind: address already in use
Error: failed to start containers: srs-stack片

找到原因了，端口8080被占用

4.修改修改占用端口，我的是frp的 vhost_http_port=8080占用了，我将它注释掉

# vhost_http_port=8080

每个人根据自己的服务进程修改掉占用端口的程序即可

再次启动

docker start srs-stack

报错：

Error response from daemon: driver failed programming external connectivity on endpoint srs-stack (2f9ade46a5f6d4b971622986c8304b34488c0a5440082a190a190f1a4467cba9): Bind for 0.0.0.0:1935 failed: port is already allocated

5.修改配置文件docker-compose.yml，首先查找该文件

find / -name docker-compose.yml 2>/dev/null

运行结果：

/www/dk_project/dk_app/dk_rtmp/docker-compose.yml

用ftp工具下载该配置文件，打开，内容如下：

version: '3'
services:
  nginx-rtmp:
    image: tiangolo/nginx-rtmp
    ports:
      - ${RTMP_PORT}:1935
    volumes:
      - ./data:/data
    restart: unless-stopped

将1935改成1936

6.修改.env文件

在相同目录下可以找到，同样的，下载打开

RTMP_PORT=1935
RTMP_PATH=/www/dk_project/dk_app/dk_rtmp

将1935改成1936

7.执行修改

cd /www/dk_project/dk_app/dk_rtmp
docker-compose down
docker-compose up -d

8.再次运行srs-stack

docker start srs-stack

没有报错，结果如下：

[root@VM-0-14-tencentos dk_rtmp]# docker start srs-stack
srs-stack

再去启动看看，启动成功！

进入后台管理面板，成功~
