docker 二进制安装

首先所属环境为内网并且服务器拥有的开发环境不确定，需要跑当前服务所需代码，所以优先选择使用docker

docker 文档地址
https://docs.docker.com

在 install 中存在 Install Docker Engine from binaries 二进制安装
https://download.docker.com/linux/static/stable/x86_64/  选择自己所需的docker 版本。
下载下来之后是一个 tar 压缩包。之后可以按照官网指令进行。

此时的docker 无法跟随服务器进行自启动，所以需要继续进行配置。

vi /usr/lib/systemd/system/docker.service #复制docker.service 内容

systemctl daemon-reload

systemctl start docker
systemctl status docker
systemctl enable docker

docker.service 内容 此内容为 https://www.runoob.com/docker/centos-docker-install.html 中 curl -sSL https://get.daocloud.io/docker | sh 安装的docker 所拥有的，更改了下 docker 镜像内容

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
# 此处需要删除 docker.socket 
# 参考此篇文章 https://www.cnblogs.com/fat-girl-spring/p/14236356.html
Requires=containerd.service

[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

# 服务器存储时最大存储空间为 /home 路径下，所以需要修改docker 镜像的存储位置
# 参考此篇文章修改 docker.service 的镜像存储位置 https://www.modb.pro/db/47890
ExecStart=/usr/bin/dockerd  --graph=/usr/local/docker/dockerd --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=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.
LimitNOFILE=infinity
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
