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

测试：

在本地/mydata/nginx/html/下放入一个index.html，

重启：docker restart nginx

访问http://localhost/
