Docker安装Nginx问题及错误分析

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/conf

									touch /mydata/nginx/conf/nginx.conf

									vim /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
