## 前言 ##

## 1、docker安装Nginx ##

### 1.1、观察nginx是否可下载 ###

healerjean$ docker search nginx

### 1.2、开始安装 ###

healerjean$ docker pull nginx

## 2、先运行这个nginx ##

healerjean$ docker run -it -p 80:80 nginx

### 3.1、查看这个nginx的容器id号 ###

docker ps
    
    healerjean$ docker ps
    CONTAINER ID        IMAGE               COMMAND                  CREATED                  STATUS              PORTS                NAMES
    9fbe362214a6        nginx               "nginx -g 'daemon of…"   Less than a second ago   Up 2 seconds        0.0.0.0:80->80/tcp   objective_chandrasekhar
    healerjean$

## 2、进入这个容器 ##

### 2.1、docker exec ：在运行的容器中执行命令 ###

-d :分离模式: 在后台运行
    		-i :即使没有附加也保持STDIN（标准输入） 打开,以交互模式运行容器，通常与 -t 同时使用；
    		-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；
    
    
    docker exec -it 9fbe362214a6  /bin/bash

docker exec -it 9fbe362214a6  /bin/bash 
    
    
    
    healerjean$ docker exec -it 9fbe362214a6  /bin/bash

## 3、docker cp ##

#### 3.1、将容器29df10f32d44:/etc/nginx/nginx.conf 目录拷贝到主机/Users/healerjean/Desktop目录下 ####

:~ healerjean$  docker cp  29df10f32d44:/etc/nginx/nginx.conf /Users/healerjean/Desktop

#### 3.2、将主机/Users/healerjean/Desktop/AAA.md 拷贝到容器29df10f32d44:/etc/nginx/中 ####

docker cp /Users/healerjean/Desktop/AAA.md 29df10f32d44:/etc/nginx/

:~ healerjean$ docker cp /Users/healerjean/Desktop/AAA.md 29df10f32d44:/etc/nginx/
    
    
    :~ healerjean$ docker exec -it 29df10f32d44 /bin/bash
    root@29df10f32d44:/# cd /etc/nginx/
    root@29df10f32d44:/etc/nginx# ls -l
    total 44
    -rw-r--r-- 1  501 dialout 1519 Jul 27 08:08 AAA.md
    drwxr-xr-x 1 root root    4096 Aug 28 07:10 conf.d
    -rw-r--r-- 1 root root    1007 Jul 24 13:02 fastcgi_params
    -rw-r--r-- 1 root root    2837 Jul 24 13:02 koi-utf

    -rw-r--r-- 1 root root    5231 Jul 24 13:02 mime.types
    lrwxrwxrwx 1 root root      22 Jul 24 13:02 modules -> /usr/lib/nginx/modules
    -rw-r--r-- 1 root root     643 Jul 24 13:02 nginx.conf
    -rw-r--r-- 1 root root     636 Jul 24 13:02 scgi_params
    -rw-r--r-- 1 root root     664 Jul 24 13:02 uwsgi_params
    -rw-r--r-- 1 root root    3610 Jul 24 13:02 win-utf
    root@29df10f32d44:/etc/nginx#

## 4、 -v 挂在本地目录到容器中 ##

#### 4.1、建议启动的时候挂载 ：:ro 表示分配给只读权限（这样容器就可以使用宿主主机的目录了） ####

docker run -p 80:80  -v /Users/healerjean/Desktop:/usr/local/mynginx:ro -d nginx

JeandeMBP:~ healerjean$ docker run -p 80:80 -it -v /Users/healerjean/Desktop:/usr/local/mynginx:ro -d nginx
