docker实验一：在docker运行nginx-起风网

教程参考http://www.runoob.com/docker/docker-install-nginx.html
由于菜鸟上的教程很多细节都没写出来，在这里尽量把细节都记录下来。

目标：通过docker运行nginx
前提：了解nginx的基本用法，了解docker基本指令

step1：宿主机准备

root@c-pc:/opt/docker_nginx# docker pull nginx
...
root@c-pc:/opt/docker_nginx# ls
conf  log  www

conf存放nginx的配置文件，log存放nginx的日志，www存放模板文件，见下图

root@c-pc:/opt/docker_nginx# tree 
.
├── conf
│   └── nginx.conf
├── log
│   ├── access.log
│   └── error.log
└── www
    └── index.html

以下是nginx.conf内容

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /opt/nginx/log/access.log;
    error_log /opt/nginx/log/error.log;

    ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    ##
    # Virtual Host Configs
    ##

    server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /opt/nginx/www;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
        }

    }
}

以上这个配置从nginx的默认配置文件复制出来的，改动log、root相关内容，即：

...
access_log /opt/nginx/log/access.log;
error_log /opt/nginx/log/error.log;
...
root /opt/nginx/www;
...

index.html

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
</head>
<body>
<h2>Hello docker nginx</h1>
</body>
</html>

step2:

启动容器

root@c-pc:/opt/docker_nginx# docker run -p 8093:80 --name mynginx  -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/www:/opt/nginx/www -v $PWD/log:/opt/nginx/log  -d nginx
026f7dc3dfa4362210a5273775e01222c6b622a9298ec20e9d53f46d9bc72f20

命令说明：

  -p 8093:80：将容器的80端口映射到主机的8093端口
  -name mynginx：将容器命名为mynginx
  -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：将主机中当前目录下的nginx.conf挂载到容器的/etc/nginx/nginx.conf
  -v $PWD/www:/opt/nginx/www：将主机中当前目录下的www挂载到容器的/opt/nginx/www，参考nginx.conf的root配置
  -v $PWD/log:/opt/nginx/log：将主机中当前目录下的log挂载到容器的/opt/nginx/log，参考nginx.conf的log配置

step3:测试是否正常

在主机浏览器打开
