配置Cobra（Cobra配置方法）
mysql> update mysql.user set authentication_string=password('new_password') where user='root' and Host ='localhost';
mysql> flush privileges;
mysql> quit;
GBK: create database cobra DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;
UTF8: CREATE DATABASE `cobra` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
cp config.example config
vim config
初始化数据库表结构和数据
python cobra.py install
启动Cobra
python cobra.py start &
日志信息
tail -f logs/cobra.log
*查看容器ip
sudo docker inspect da8609d69f7d
*给运行中的容器，添加端口映射;把80端口映射到主机的8000端口
docker run -d -p 8000:80 cobra /bin/bash
*查看运行过的docker
sudo docker ps -a
*保存操作过的容器为镜像
sudo docker commit da8609d69f7d cobra
*查看是否已保存
sudo docker images
*对于 run 命令可以使用 -it 参数进入 bash 来 -d保持容器后台运行
$docker run -d -i -t -p 5000:5000 cobra /bin/bash
*直接进入容器终端
docker attach 2aadecbc816f
*vim Dockerfile
FROM cobra
ADD mysite.tar /tmp/
RUN mv /tmp/mysite/* /var/www/html
EXPOSE 5000
CMD ["/root/start.sh"]
*生成新的镜像，退出时删除
docker build -rm -t mysite
