源码安装docker

下载地址

安装包官方地址：https://download.docker.com/linux/static/stable/x86_64/

1.下载安装包

wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.6.tgz

2.解压到当前文件夹

tar xzvf docker-20.10.6.tgz

3.将解压出来的docker文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

4.在/etc/systemd/system/目录下新增docker.service文件

vim /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
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=127.0.0.1 --graph /data/docker
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
  
[Install]
WantedBy=multi-user.target

记得修改IP地址：–insecure-registry=127.0.0.1（此处改成你的ip） --graph /data/docker 指定docker运行的家目录，默认是在/var/lib/docker

5.启动docker

#给docker.service文件添加执行权限
chmod +x /etc/systemd/system/docker.service

#重新加载配置文件
systemctl daemon-reload 

#启动
systemctl start docker

#设置开机启动
systemctl enable docker.service

#查看docker服务状态
systemctl status docker

6.查看文件存储路径

[root@localhost ncayu]# docker info |grep "Docker Root"
 Docker Root Dir: /data/docker
