kylin-v10安装docker和docker-compose ​

预先检查下linux上是否有docker和docker-compose还有podman ​

bash
which docker
which docker-compose
which podman

podman会导致docker无法运行，需要卸载podman

当然也要确认podman没有被使用

bash
podman ps -a
bash
yum remove podman -y

查看cpu类型

bash
arch

安装docker和docker-compose ​

首先去下载docker和docker-compose 根据cpu类型下载 https://download.docker.com/linux/static/stable/

本次选择x86_64

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

选择linux 64的

获取之后将文件上传到服务器上

将二进制复制到系统的bin目录下 ​

解压docker安装包并将二进制复制到系统bin目录下

bash
tar -zxvf docker-20.10.17.tgz
mv docker/* /usr/bin/
bash
mv docker-compose-linux-x86_64 /usr/bin/docker-compose
chmod +x /usr/bin/docker-compose

编辑systemd文件 ​

bash
vi  /usr/lib/systemd/system/docker.service
text
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target nss-lookup.target docker.socket firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service
Requires=docker.socket

[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 fd:// --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNPROC=infinity
LimitCORE=infinity

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# 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
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

添加docker用户组 ​

bash
groupadd docker
usermod -aG docker 用户1 用户2
usermod -aG docker root

创建daemon.json文件 ​

bash
vi /etc/daemon.json

内容如下

json
{
    "registry-mirrors": ["https://registry.docker-cn.com"],
    "exec-opts": ["native.cgroupdriver=systemd"]
}

启动docker ​

bash
systemctl daemon-reload
systemctl enable docker
systemctl start docker
systemctl status docker

测试docker是否安装成功 ​

bash
docker run hello-world
