docker安装、升级、以及sudo dockerd --debug查看启动失败的问题

1、docker安装包tar下载地址

Index of linux/static/stable/x86_64/

2、下载tgz文件并解压

tar -zxvf docker-24.0.8.tgz

解压后docker文件夹下位docker相关文件

3、将老版本docker相关文件，备份

将 /usr/bin/docker下docker相关的文件，mv到备份目录

4、将新版本docker二进制文件，复制到/usr/bin/目录下

docker version验证版本

5、修改相关配置文件，以及解决docker启动失败的问题

/etc/docker/daemon.json 

{
        "data-root": "/work/docker/yourRootdir",
        "registry-mirrors": [
        "https://dockerproxy.com",
        "https://mirror.baidubce.com",
        "https://docker.m.daocloud.io",
        "https://docker.nju.edu.cn",
        "https://docker.mirrors.sjtug.sjtu.edu.cn"
        ]
}

升级前的docker18，配置文件中rootdir参数是 graph

升级到docker20后，将graph改为data-root，否则docker启动会报错
 

通过命令查看docker启动的具体异常日志  

sudo dockerd --debug

6. 将docker注册为系统服务

vim /usr/lib/systemd/system/docker.service
