How Docker runs nginx and mounts local directories into images

1 Pull the image from hup

docker pull nginx

2 Create the directory to be mounted

mkdir -p /data/nginx/{conf,conf.d,html,logs}

3 You must have a configuration file before you can start the container

3.1 vim /data/ conf/nginx.conf

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid    /var/run/nginx.pid;


events {
  worker_connections 1024;
}


http {
  include    /etc/nginx/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 /var/log/nginx/access.log main;

  sendfile    on;
  #tcp_nopush   on;

  keepalive_timeout 65;

  #gzip on;

  include /etc/nginx/conf.d/*.conf;
}

3.2 vim /data/nginx/conf.d/default.conf

server { 
  listen    80; 
  server_name localhost; 
 
  #charset koi8-r; 
  #access_log /var/log/nginx/log/host.access.log main; 
 
  location / { 
    root  /data/nginx/html; 
    # root  /usr/nginx/html; 
    index index.html index.htm; 
    autoindex on; 
  try_files $uri /index/index/page.html; 
    #try_files $uri /index/map/page.html; 
  } 
 
  #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  /usr/share/nginx/html; 
  } 
 
  # proxy the php scripts to apache listening on 127.0.0.1:80 
  # 
  #location ~ \.php$ { 
  #  proxy_pass  http://127.0.0.1; 
  #} 
 
  # pass the php scripts to fastcgi server listening on 127.0.0.1:9000 
  # 
  #location ~ \.php$ { 
  #  root      html; 
  #  fastcgi_pass  127.0.0.1:9000; 
  #  fastcgi_index index.php; 
  #  fastcgi_param script_filename /scripts$fastcgi_script_name; 
  #  include    fastcgi_params; 
  #} 
 
  # deny access to .htaccess files, if apache's document root 
  # concurs with nginx's one 
  # 
  #location ~ /\.ht { 
  #  deny all; 
  #} 
}

4 Start the container

#将容器中nginx的80端口映射到本地的81端口
docker run --name nginx81 -d -p 81:80 -v /data/nginx/html:/usr/share/nginx/html -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/logs:/var/log/nginx -v /data/nginx/conf.d:/etc/nginx/conf.d -d nginx:latest

5 View the started Container

[root@dc01 ~]# docker ps
container id image command created status ports names
