Docker安装Nginx问题及错误分析
作者:菠了个白了个菜
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/
