Automatically install using the official installation script
The installation command is as follows:
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
You can also use the domestic daocloud one-click installation command:
curl -sSL https://get.daocloud.io/docker | sh
Docker offline installation
1. Docker installation
1. Official address of the installation package: https://download.docker.com/linux/static/stable/x86_64/
You can first download it locally and then upload it to the server through the ftp tool, or use the command to download on the server.
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz
2. Unzip
tar -zxvf docker-18.06.3-ce.tgz
3. Copy the decompressed docker file to the /usr/bin/ directory
cp docker/* /usr/bin/
4. Create docker.service file
Enter /etc/systemd/system/the directory and create docker.servicea file with the following content, so that docker can be registered as a service

5. Start 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（每次有修改docker.service文件时都要重新加载下）
systemctl daemon-reload
# 启动
systemctl start docker
# 设置开机启动
systemctl enable docker.service

2. Docker-compose installation
# docker-compose下载并放到/usr/local/bin/下面：
curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 下载好docker-compose的前提下，拷贝到指定位置
sudo cp docker-compose /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
docker-compose -v
# 最后使用 docker-compose -v 命令测试是否安装成功（如果提示“没有那个文件或目录”可以重启下服务器再试试）
question
1. CentOS7 installation docker encounters [Errno 14] curl#35 - "TCP connection reset by peer problem solving:
Install the required software packages. yum-util provides the yum-config-manager function, and the other two are dependent on the devicemapper driver.
yum install -y yum-utils device-mapper-persistent-data lvm2
1. Change to Aliyuan
First of all, this problem is because the official docker image cannot be accessed in China, so we have to use domestic sources to access it. I have also tried the 163 source before, but it has not been able to solve it, but later I changed the Alibaba source and successfully solved this problem. Question, let’s stop talking nonsense and state it directly:
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
If successful, the following prompt will appear:
repo saved to /etc/yum.repos.d/docker-ce.repo
2. View all versions in the docker warehouse and enter the command to see the version information of docker, as follows: (If the kernel version is low and the docker version is high, installation errors will occur)
yum list docker-ce --showduplicates | sort -r
We can install the specified version using sudo yum install <docker的版本>, here I use sudo yum install docker-cethe highest version installed by default. For example
sudo yum install docker-ce.x86_64 3:24.0.2-1.el7
3. Start and join the boot startup
sudo systemctl start docker && sudo systemctl enable docker
4. Check whether docker is installed successfully and check the version information. The following picture appears. Congratulations on the successful installation of docker! You can see the information of Client and Server.
docker version
sudo docker run hello-world
2. Because an old version of docker has been installed before, the following error was reported during installation:
Transaction check error:

Uninstall old versions of packages
$ sudo yum erase docker-common-2:1.12.6-68.gitec8512b.el7.centos.x86_64
Install docker again
$ sudo yum install docker-ce
三、No Presto metadata available for docker-ce-stable
yum install docker-ce -y
四、Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
yum provides '*/applydeltarpm'
yum install deltarpm -y
DOCKER COMPOSE
sudo curl -L "https://github.com/docker/compose/releases/download/1.28.0-rc1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version
docker-compose up / docker-compose up -d 起服务（要有docker-compose.yml）
docker start nginx
docker-compose stop
question:
dlopen: /lib64/libc.so.6: version `GLIBC_2.28’ not found
The error message means that there is no GLIBC_2.28 version, upgrade version:
1. Download glibc-2./28.tar.gz (any directory)
wget https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
2. Decompress and compile other operations (use root to operate with full authority, the last two steps take a long time)
[root@hadoop101 opt]# tar -zxvf glibc-2.28.tar.gz
[root@hadoop101 opt]# cd glibc-2.28
[root@hadoop101 glibc-2.28]# mkdir build
[root@hadoop101 glibc-2.28]# cd build
[root@hadoop101 build]# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
[root@hadoop101 build]# make -j 8
[root@hadoop101 build]# make install
If an error is reported:
These critical programs are missing or too old: make bison compiler
View bison version:
bison -V
Use yum to install bison
yum install -y bison
Then upgrade make:
first ~/.bash_profileaddPATH=$HOME/local/bin:$PATH
source ~/.bash_profile
ln -s $HOME/local/bin/make $HOME/local/bin/gmake
Download first:
wget https://ftp.gnu.org/gnu/make/make-4.3.tar.gz
tar -zvxf make-4.3.tar.gz
cd make-4.3
./configure --prefix=$HOME/local
make && make install
