Centos7离线安装Docker和docker-compose

Centos7离线安装Docker和docker-compose

 

1.查看系统环境，内核版本3.10及以上

#cat /etc/redhat-release

#uname -r

2.准备docker安装包和安装脚本

Docker官方下载地址：https://download.docker.com/linux/static/stable/x86_64/

根据自己需要的版本进行下载，这里我选用最新的docker-20.10.9.tgz

3.docker安装脚本

创建install-docker.sh脚本：

#cd /opt/

#vi install-docker.sh

#!/bin/sh

usage(){

echo "使用方法: $0 FILE_NAME_DOCKER_CE_TAR_GZ"

echo " $0 docker-20.10.5.tgz"

echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"

echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.5.tgz"

echo ""

}

SYSTEMDDIR=/usr/lib/systemd/system

SERVICEFILE=docker.service

DOCKERDIR=/usr/bin

DOCKERBIN=docker

SERVICENAME=docker

 

if [ $# -ne 1 ]; then

usage

exit 1

else

FILETARGZ="$1"

fi

 

if [ ! -f ${FILETARGZ} ]; then

echo "Docker binary tgz files does not exist, please check it"

echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"

echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.5.tgz"

exit 1

fi

 

echo "##unzip : tar xvpf ${FILETARGZ}"

tar xvpf ${FILETARGZ}

echo

 

echo "##binary : ${DOCKERBIN} copy to ${DOCKERDIR}"

cp -p ${DOCKERBIN}/* ${DOCKERDIR} >/dev/null 2>&1

which ${DOCKERBIN}

 

echo "##systemd service: ${SERVICEFILE}"

echo "##docker.service: create docker systemd file"

cat >${SYSTEMDDIR}/${SERVICEFILE} <<EOF

授权install-docker.sh为可以执行脚本

#chmod +x install-docker.sh

4.下载好的docker包上传至/opt目录下

5.执行install-docker.sh脚本，进行安装docker

#./install-docker.sh docker-20.10.9.tgz

版本号打印

安装成功

#docker --version

6.安装docker-compose

下载安装包:

https://github.com/docker/compose/releases

下滑到Assets，点击Show all 26 assets，下载如下版本

7.将下载好的docker-compose-Linux-x86_64上传到 /usr/local/bin/目录下

#cd /usr/local/bin/

8.修改名称进行授权即可

#mv docker-compose-linux-x86_64 docker-compose

#chmod +x docker-compose

9.查看docker-compose版本号，安装完成

#docker-compose --version
