服务器重启后执行docker-compose up -d报错:

Starting nginx ... 
php is up-to-date
Starting nginx ... errorERROR: for nginx  Cannot start service nginx: driver failed programming external connectivity on endpoint nginx (b2a83540af157cc42157760afe9aec5f8876fbeeb9b495bda3454de89693d70f): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use

原因:
根据提示Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use,知道是端口被占用了, 通过netstat查看占用端口的是本机nginx, 杀掉本机的nginx后重新启动docker的就行了

解决:
1: 找到占用端口的程序netstat -anp|grep 80

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1061/nginx: worker

2: 杀掉进程

kill -9 1061

再执行docker-compose up -d就成功了
