Docker 安装Nginx

前一章docker安装成功了，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

docker images

看到只有一个测试的镜像。

拉取镜像：

docker pull nginx

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：

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

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

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
