readhalt7.4 安装 docker

Linux系统下docker安装

1.下载docker文件

cd /opt/
wget https://download.docker.com/linux/static/s...

2.解压文件

tar -xvf docker-18.06.1-ce.tgz

3.将解压出来的docker文件内容移动到 /usr/bin/目录下

cp docker/* /usr/bin/

4.将docker注册为服务

vim /etc/systemd/system/docker.service
具体编辑的时候一定去除#前面的单引号
以下是文件内容：
[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
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

5.启动

chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker
systemctl daemon-reload #重新加载配置文件
systemctl start docker #启动Docker
systemctl enable docker.service #设置开机自启

systemctl status docker #查看Docker状态
docker -v #查看Docker版本
