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/
