=创建Mysql Compose=
<pre>

2.1、创建Mysql管理目录

mkdir mysql
mkdir mysql/data
cd mysql
mkdir conf
cd conf

2.2、创建mysql配置文件

vi my.cnf #要优化
[mysqld]
user=mysql
port=3306
datadir=/var/lib/mysql
socket=/var/run/mysqld/mysqld.sock
pid-file=/var/run/mysqld/mysqld.pid

# 1、进入nginx管理界面
docker container exec -it e7c9152c93ac /bin/bash

nameserver 8.8.4.4

修改Docker配置文件/etc/default/docker如下：

DOCKER_OPTS="--registry-mirror=http://aad0405c.m.daocloud.io"
使用service docker restart重启Docker服务即可。

现在使用docker pull拉取镜像真是特别爽，速度很快，再次感谢DaoCloud公司

要加apt update

apt 可以改源的呢

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

#注意
# 添加解压nginx包到/tmp目录下自带了解压功能了哦老是一时忘记
ADD nginx-1.12.1.tar.gz /tmp
