CentOS7 上学习使用docker 【安装Nginx】

下载镜像

docker pull nginx

启动容器

docker run -d -p 8080:80 nginx

把容器内的nginx的80端口，映射到当前服务器的8080端口，浏览器输入http://192.168.1.120:8080/，就可以看到nginx已启动，

删除nginx容器

1. 先查看在运行的容器

[root@izbp1e0h5tks006vnlaro4z bin]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
94db415a384f        nginx               "nginx -g 'daemon ..."   About an hour ago   Exited (0) 18 minutes ago                       affectionate_kowalevski
b136815d5dfc        nginx               "nginx -g 'daemon ..."   About an hour ago   Created                                         sad_heisenberg

2. 停止容器

[root@izbp1e0h5tks006vnlaro4z bin]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                  NAMES
4e882347dfec        nginx               "nginx -g 'daemon ..."   About a minute ago   Up About a minute   0.0.0.0:8081->80/tcp   ecstatic_noyce
[root@izbp1e0h5tks006vnlaro4z bin]# docker stop 4e882347dfec
4e882347dfec

3. 删除容器

[root@izbp1e0h5tks006vnlaro4z bin]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
94db415a384f        nginx               "nginx -g 'daemon ..."   About an hour ago   Exited (0) 23 minutes ago                       affectionate_kowalevski
b136815d5dfc        nginx               "nginx -g 'daemon ..."   About an hour ago   Created                                         sad_heisenberg
[root@izbp1e0h5tks006vnlaro4z bin]# docker rm b136815d5dfc
b136815d5dfc
[root@izbp1e0h5tks006vnlaro4z bin]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
94db415a384f        nginx               "nginx -g 'daemon ..."   About an hour ago   Exited (0) 23 minutes ago                       affectionate_kowalevski
[root@izbp1e0h5tks006vnlaro4z bin]# docker rm 94db415a384f
94db415a384f
[root@izbp1e0h5tks006vnlaro4z bin]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

指定容器nginx的参数

docker run --name nginx-001 -d -p 8080:80 -v /home/docker/nginx/html:/usr/share/nginx/html nginx

-p 参数是把 宿主的8080端口映射到容器的80端口 这里要注意-v是数据卷，可以主机和容器之间共享/home/docker/nginx/html这个目录，在容器里面就是/usr/share/nginx/html。其实这就是我们的代码目录，调试代码就是靠共享目录实现的，很方便！！

修改容器里面的配置文件

#进入容器
$docker exec -it nginx-001 bash
#安装工具
apt-get update
apt-get install vim
#查看和修改nginx的配置信息
vim /etc/nginx/conf.d/default.conf
