安装docker
1.下载软件
在CentOS中下载docker,直接运行
yum install -y docke-io
因为使用代理,所以在虚拟机上面使用代理上网,无法连接网络
首先需要配置 /etc/profile
Http_proxy="http://your_proxy_ip:porxy_port"
Https_proxy="http://your_proxy_ip:porxy:port"
设置其生效:
Source /etc/profile
再次运行yum命令,安装成功
2.pull镜像
使用search:
docker search java
出现错误如下:
Pulling repository docker.io/library/busybox
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/busybox/images. You may want to check your internet connection or if you are behind a proxy.
需要设置docker提取的代理:
1.-mkdir
/etc/systemd/system/docker.service.d
2.创建http_proxy.conf文件
[Service]
Environment="HTTP_PROXY=http://10.131.3.10:8080"
3.设置daemon
sudo systemctl daemon-reload
4.重新启动docker
sudo systemctl restart docker
