1.原因说明
经常要安装Docker进行测试，安装的过程虽然不复杂，但是会消耗一些时间，故整理了自动化安装脚本，本次安装的文件是docker-20.10.13.tgz其他版本未测试。
2.脚本内容
脚本文件dockerInstall.sh内容如下：
#!/bin/bash echo "(1/6): 解压Docker安装文件..." tar -zxvf docker-20.10.13.tgz sleep 5 echo "(1/6): Docker安装文件解压完毕" echo "(2/6): 迁移Docker文件..." mv docker/* /usr/bin/ echo "(2/6): Docker文件迁移完成" echo "(3/6): 将Docker添加到service服务..." cat <<'EOF' > /etc/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always StartLimitBurst=3 StartLimitInterval=60s LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity TasksMax=infinity Delegate=yes KillMode=process [Install] WantedBy=multi-user.target EOF sleep 2 systemctl daemon-reload echo "(3/6): Docker添加到service服务完成" echo "(4/6): 首次启动Docker..." systemctl start docker sleep 2 echo "(4/6): Docker首次启动完毕" echo "(5/6): 查看Docker状态..." systemctl status docker echo "(5/6): Docker状态查看完毕" echo "(6/6): 查询Docker版本..." docker version echo "(6/6): Docker版本查看完毕"
3.脚本执行
首先要赋可执行权限chmod +x dockerInstall.sh，然后，这里小伙伴要 1注意了、2注意了、3注意了：执行命令的时候要用source dockerInstall.sh，执行结果如下：

4.总结
没有写复杂的可传递参数的脚本，不同版本的Docker安装过程可能有区别。
