安装docker
卸载旧版本（没有则不用）：
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
复制安装包到服务器：
[root@localhost dockerPackage]# ls
containerd.io-1.4.4-3.1.el7.x86_64.rpm docker-ce-rootless-extras-20.10.6-3.el7.x86_64.rpm libseccomp-2.3.1-4.el7.x86_64.rpm
docker-ce-20.10.6-3.el7.x86_64.rpm docker-ce-selinux-17.03.3.ce-1.el7.noarch.rpm
docker-ce-cli-20.10.6-3.el7.x86_64.rpm docker-scan-plugin-0.7.0-3.el7.x86_64.rpm installDocker.sh
[root@localhost dockerPackage]# rpm -ivh ./*.rpm --force --nodeps
开机自启动：
systemctl enable docker 或 chkconfig docker on
启动docker：
systemctl start docker 或者 service start docker
测试成功否（有网络）：
docker run hello-world
使用docker-compose时出现问题
[root@localhost init]# ./init.sh
dir: dzzjwithdocker id: 30ff214768b8
Starting dzzjwithdocker_zhgl_6.1_dzzj_1 ... error

[root@localhost init]#
最后通过安装 解决
https://centos.pkgs.org/7/centos-x86_64/libseccomp-2.3.1-4.el7.x86_64.rpm.html
yum install libseccomp
