问题：
在Docker中装Nginx时遇到了如下错误： docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused “process_linux.go:424: container init caused “rootfs_linux.go:58: mounting /”/docker/nginx/conf/” to rootfs /"/var/lib/docker/overlay2/126c244dc6ee7095b1501a503eb361bade4fc255601ec0b0fe96238b58178958/merged/" at /"/var/lib/docker/overlay2/126c244dc6ee7095b1501a503eb361bade4fc255601ec0b0fe96238b58178958/merged/etc/nginx/nginx.conf/" caused /“not a directory/”"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type.
我是安装了镜像后直接就去 docker run / -p 80:80 / --name nginx / -d --restart=always / -v /mydata/nginx/html:/usr/share/nginx/html / -v /mydata/nginx/conf/nginx.conf:/etc/nginx/nginx.conf / -v /mydata/nginx/logs:/var/log/nginx / nginx
之后就出现了错误。
错误分析：
错误中我看的懂的地方说：尝试把目录装载到文件夹上，/nginx/nginx.conf/" caused /“not a directory/”",哒哒哒…什么的，这里我看了主机上的文件路径，发现本地创建的nginx.conf是个文件夹nginx.conf/，不是我想要的文件nginx.conf。
正确的操作方法：
创建文件 mkdir -p /mydata/nginx/conftouch /mydata/nginx/conf/nginx.confvim /mydata/nginx/conf/nginx.conf 在nginx.conf中写入官方初始的内容 #user nobody;worker_processes 1;#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#pid logs/nginx.pid;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }}然后运行 docker run / -p 80:80 / --name nginx / -d --restart=always / -v /mydata/nginx/html:/usr/share/nginx/html / -v /mydata/nginx/conf.d:/etc/nginx/conf.d / -v /mydata/nginx/conf/nginx.conf:/etc/nginx/nginx.conf / -v /mydata/nginx/logs:/var/log/nginx / nginx 测试：在本地/mydata/nginx/html/下放入一个index.html， 重启：docker restart nginx 访问http://localhost/
