Docker安装Nginx教程实现图例讲解

这里来安装下Nginx试下。

注意要明确一点，镜像是类，容器是对象。

查看当前的镜像

看到只有一个测试的镜像。

拉取镜像：

下载成功后查看，镜像已经被下载下来了：

使用 nginx 镜像

运行容器：

查看容器运行情况：

然后在浏览器输入网址：

修改文件：

[root@VM_0_4_centos bin]# docker ps
CONTAINER ID    IMAGE        COMMAND         CREATED       STATUS       PORTS        NAMES

8bf811453641    nginx        "nginx -g 'daemon of…"  4 minutes ago    Up 4 minutes    0.0.0.0:80->80/tcp  nginx_test

记住这里的 CONTAINER ID ，这是容器的ID

进入容器，修改：

[root@VM_0_4_centos bin]# docker exec -it 8bf811453641 /bin/bash
root@8bf811453641:/# cd /usr/share/nginx/html
root@8bf811453641:/usr/share/nginx/html# echo "hello docker">index.html
root@8bf811453641:/usr/share/nginx/html# exit

这是查看，修改的已经生效了。

如果想停止容器：

docker stop containerId // containerId 是容器的ID
[root@VM_0_4_centos bin]# docker stop 8bf811453641

然后用docker ps 看容器运行状态就行。

到此，容器运行完毕，总体来说非常的简单。

下面追加挂载方法先创建目录

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

nginx配置文件

/data/nginx/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;

  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;
    }

  }

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

/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;

    #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;
  #}
}

/data/nginx/html/index.html

<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
  <title>系统时间</title>
</head>
<body>
<h1 id="datetime">
  <script>
    setInterval("document.getElementById('datetime').innerHTML=new Date().toLocaleString();", 1000);
  </script>
</h1>
</body>

删除容器

docker rm -f nginx-test

重新映射启动容器

docker run --name nginx-test -d -p 80:80 -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

再次运行
