CentOS7中Docker的安装与配置：

在上面安装Docker时，CentOS是可以访问外网安装的。

如果是在内网服务器上，即这台服务器没法访问外网应该如何安装Docker。

# 实现 #

首先下载docker的离线安装包

[https://download.docker.com/linux/static/stable/x86\_64/][https_download.docker.com_linux_static_stable_x86_64]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

这里选择20.10.7下载

下载之后将其上传到服务器上某路径下进行解压

tar -zvxf docker-20.10.7.tgz

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

解压之后将docker目录复制到/usr/bin目录下

cp docker/* /usr/bin/

然后新建一个docker.service系统配置文件

[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
    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

将此文件复制到服务器上

这里是在本地Windows系统上新建文件然后使用xftp将其上传到CentOS服务器

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

然后在服务器上将其复制到/etc/systemd/system/下

cp docker.service /etc/systemd/system/

添加文件权限

chmod +x /etc/systemd/system/docker.service

重新加载配置文件

systemctl daemon-reload

启动docker

systemctl start docker

验证docker版本

docker version

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

##  卸载Docker ##

停止docker服务

systemctl stop docker

删除配置文件

rm -f /etc/systemd/system/docker.service

删除docker文件

rm -rf /usr/bin/docker*

重新加载配置文件

systemctl daemon-reload
