制作docker.service文件

创建docker.service文件

cd /etc/systemd/system/
touch docker.service

编辑docker.service文件

vim docker.service

// 注意，将其中的ip地址，改成您的服务器地址，其它参数不用改。
//--insecure-registry=192.168.88.88

[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=192.168.88.88
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

制作一键安装脚本

touch install.sh

#!/bin/sh
 
echo '解压tar包'
tar -xvf $1
echo '将docker目录下所有文件复制到/usr/bin目录'
cp docker/* /usr/bin
echo '将docker.service 复制到/etc/systemd/system/目录'
cp docker.service /etc/systemd/system/
echo '添加文件可执行权限'
chmod +x /etc/systemd/system/docker.service
echo '重新加载配置文件'
systemctl daemon-reload
echo '启动docker'
systemctl start docker
echo '设置开机自启'
systemctl enable docker.service
echo 'docker安装成功'
docker -v

制作一键卸载脚本

touch uninstall.sh

#!/bin/sh
 
echo '停止docker'
systemctl stop docker
echo '删除docker.service'
rm -f /etc/systemd/system/docker.service
echo '删除docker文件'
rm -rf /usr/bin/docker*
echo '重新加载配置文件'
systemctl daemon-reload
echo '卸载成功'

配置阿里云镜像源

打开阿里云的官网，搜索容器，找到容器与镜像服务

在这里插入图片描述

进入容器与镜像服务页面，点击镜像加速器。
