阿里云的LINUX中安装办法

[root@xgblog ~]# yum install docker-compose -y
. . . 
Complete!
[root@xgblog ~]# docker-compose -v
bash: /usr/local/bin/docker-compose: Permission denied
[root@xgblog ~]# chmod +x /usr/local/bin/docker-compose
[root@xgblog ~]# docker-compose -v
docker-compose version 1.23.2, build 1110ad01

不行的话再加软链
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

docker exec -it  xxx（ID）  redis-cli

• 查询最近的20条日志

docker logs -f -t --tail=10 容器名

• 查询指定日期的最近的20条日志

docker logs -f -t --since="2017-05-31" --tail=10 容器名

• 先执行 (需要执行很久很久)

apt-get update

• 再执行

apt-get install vim

上面的失败了, 下面的一种方法继续尝试

在Linux里面依次输入下面的命令：1，下载最新的yum-3.2.28.tar.gz并解压

wget http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz
tar xvf yum-3.2.28.tar.gz  

• 进入目录，运行安装

cd yum-3.2.28 
yummain.py install yum

• 最后更新系统。

yum check-update
yum update
yum clean all
