作者:久末丶 时间:2021-11-30 08:49:19
安装前将所有的软件包上传到系统的/opt路径,所有的操作都在/opt目录下
一、解压文件
tar -xzvf docker-19.03.0.tgz
二、拷贝解压后的文件到/usr/bin/下面
cp docker/* /usr/bin/
三、加入系统文件
cat >/etc/systemd/system/docker.service <<-EOF
[Unit]
Description=Docker Application Container Engine
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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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
EOF
四、启动Docker
systemctl daemon-reload && systemctl start docker && systemctl enable docker.service
五、Docker配置文件
编辑daemon.json文件输入以下内容
vim /etc/docker/daemon.json
{
"log-driver":"json-file",
"log-opts":{
"max-size" :"10m","max-file":"4"
},
"registry-mirrors": ["https://6kx4zyno.mirror.aliyuncs.com"]
}
六、重启Docker
systemctl restart docker
七、检查Docker是否安装成功
docker --version
