# linux上用docker部署nginx
#### 拉取nginx官方镜像
```
docker pull nginx
```
#### 运行nginx镜像并进入容器
```
docker run -ti nginx /bin/bash
```
/bin/bash的只能用一下很基本的unix命令，我们ls一下发现nginx容器有以下目录
其中nginx的配置目录在/etc/nginx
这样我们就运行了一个基本的nginx容器了，但是怎么样才能外部能访问到呢，我们可以映射容器的端口到外部主机端口。
```
docker run -p 8888:80 -d nginx
```
这样我们就将外部的8888端口指向nginx容器的80端口了，OK，打开浏览器测试一下
可是我们每次要修改nginx的配置都要进入到容器内部去修改是不是太麻烦了，ok，目录也来映射一下。 先停止刚刚启动的容器
```
docker stop 268527ecab7c
```
在主机上创建目录/disk2/docker/nginx,在该目录下创建conf，logs，www三个目录，分别是干什么的也不用我多说了吧。 然后执行
```
docker run -p 8888:80 -v /disk2/docker/nginx/conf:/etc/nginx/conf.d -v /disk2/docker/nginx/www:/usr/share/nginx/html -v /disk2/docker/nginx/logs:/var/log/nginx -d nginx
```
在/disk2/docker/nginx/conf目录下新增文件default.conf,写入
```
server {
listen 80;
server_name localhost;
#charset koi8-r;
access_log /var/log/nginx/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 /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;
#}
}
```
然后在/disk2/docker/nginx/www目录下新增文件index.html,写入
```
Welcome to nginx in docker!
docker!!!!
```
查看结果
这样就能将容器内的目录映射到外部的目录去了，修改配置或查看日志便不用进入容器中去修改了
