docker部署nginx，通过宿主机配置控制nginx容器

操作步骤如下：
#搜索镜像

docker search nginx 
docker search nginx 
docker search nginx 

#拉去镜像

docker pull nginx 
docker pull nginx 
docker pull nginx 

#查看本地镜像

docker images 
docker images 
docker images 

#启动nginx容器

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

以上步骤可查看我的上一个博客，对其讲解比较详细

本节主要操作通过宿主机配置控制nginx容器
#在宿主机中创建挂载目录

<span class="token function">mkdir</span> -p /home/nginx/<span class="token punctuation">{<!-- --></span>conf,conf.d,html,log<span class="token punctuation">}</span> 
<span class="token function">mkdir</span> -p /home/nginx/<span class="token punctuation">{<!-- --></span>conf,conf.d,html,log<span class="token punctuation">}</span> 
mkdir -p /home/nginx/{conf,conf.d,html,log} 

#将容器里的配置信息远程复制到宿主机

<span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> 
<span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> <span class="token punctuation">[</span>root@localhost ~<span class="token punctuation">]</span> 
[root@localhost ~] [root@localhost ~] [root@localhost ~] [root@localhost ~] 

#启动nginx容器

<span class="token punctuation">[</span>root@localhost conf.d<span class="token punctuation">]</span> 
<span class="token punctuation">[</span>root@localhost conf.d<span class="token punctuation">]</span> 
[root@localhost conf.d] 

第一个-v：挂载nginx的主配置文件，以方便在宿主机上直接修改容器的配置文件
第二个-v：挂载容器内nginx的日志，容器运行起来之后，可以直接在宿主机的这个目录中查看nginx日志
第三个-v：挂载静态页面目录
第四个-v：挂载nginx子配置文件

#验证：通过修改宿主机的nginx配置文件来控制nginx容器
#复制index.html重命名为main.html,并编辑此页面区别于index.html页面内容

<span class="token function">cd</span> /home/nginx/html/ <span class="token function">cp</span> index.html main.html 
<span class="token function">cd</span> /home/nginx/html/ <span class="token function">cp</span> index.html main.html 
cd /home/nginx/html/ cp index.html main.html 

#编辑main.html区别于index.html页面内容

<span class="token function">vi</span> main.html 
<span class="token function">vi</span> main.html 
vi main.html 

#修改配置文件/conf.d/default.conf

<span class="token function">vi</span> default.conf 
<span class="token function">vi</span> default.conf 
vi default.conf 

#修改后如下：

server <span class="token punctuation">{<!-- --></span> listen 80<span class="token punctuation">;</span> listen <span class="token punctuation">[</span>::<span class="token punctuation">]</span>:80<span class="token punctuation">;</span> server_name localhost<span class="token punctuation">;</span>   location <span class="token operator">/</span> <span class="token punctuation">{<!-- --></span> root <span class="token operator">/</span>usr<span class="token operator">/</span>share<span class="token operator">/</span>nginx<span class="token operator">/</span>html<span class="token punctuation">;</span> index main<span class="token punctuation">.</span>html<span class="token punctuation">;</span> <span class="token punctuation">}</span>    error_page 500 502 503 504 <span class="token operator">/</span>50x<span class="token punctuation">.</span>html<span class="token punctuation">;</span> location = <span class="token operator">/</span>50x<span class="token punctuation">.</span>html <span class="token punctuation">{<!-- --></span> root <span class="token operator">/</span>usr<span class="token operator">/</span>share<span class="token operator">/</span>nginx<span class="token operator">/</span>html<span class="token punctuation">;</span> <span class="token punctuation">}</span>                     <span class="token punctuation">}</span>

#重启nginx容器

docker restart nginx 
docker restart nginx 
docker restart nginx 

#在浏览器中输入http://宿主机ip + nginx端口/ ，正常打开的页面应该是main.html
