# 网络源安装 #

## 配置yum源 ##

*  注：系统最好是 centos的，如果是rhel的系统，可能无法使用。【yum收费的】
 *  流程
    
     *  先进入`/etc/yum.repos.d/`目录，新建一个文件夹，将现在的全部移到文件夹中【删除也行】
     *  然后下载docker的网络源到上面目录中：`wget ftp://ftp.rhce.cc/k8s/* -P /etc/yum.repos.d/`  
        【`ftp://ftp.rhce.cc/k8s/*`这是阿里云的镜像地址】

[root@ccx ~]# 
    [root@ccx ~]# cd /etc/yum.repos.d/
    [root@ccx yum.repos.d]# mkdir bak
    [root@ccx yum.repos.d]# mv * bak
    [root@ccx yum.repos.d]# wget ftp://ftp.rhce.cc/k8s/* -P /etc/yum.repos.d/

# 离线安装 #

## 说明 ##

*  先准备一台能通外网的服务器，通过上面方法配置yum源【最好是centos系统】
 *  下载离线包的主机必须是没有安装docker-ce，如果已经安装，先卸载包及其依赖，方法见下面这个博客  
    [【yum】linux离线安装rpm包及其依赖和卸载包及其依赖][yum_linux_rpm]

## docker的rpm包准备 ##

*  rpm包正常情况一共有9个
 *  需要i使用到下面的2条命令，命令说明如下
    
     *  `mkdir /docker` ：用于存放下载的包
     *  `yum install docker-ce -y --downloaddir=/docker --downloadonly`  
        \- -downloaddir=/docker：存放路径  
        \- -downloadonly：只下载不安装

[root@ccx ~]# mkdir /docker
    [root@ccx ~]# yum install docker-ce -y --downloaddir=/docker --downloadonly

*  载完毕以后就可以将这些包全部拷贝到需要离线安装的文件中了。
 *  如果服务器很多的话，可以写个批量拷贝文件的脚本，然后把下面安装离线包的命令放在后面，一并就解压了哦。

## 离线安装docker包 ##

*  方法很简单：在存放需要docker软件包的目录下，执行下面一行代码即可了  
    `rpm -ivhU * --nodeps --force`
    
     *  \-ivhU：先安装并升级，这个U建议加上，因为有些命令安装是有升级的服务的，如果不加U就失败了【比如java】【如何确定哪些包有升级的包，直接在通外网的服务器上yum安装该服务，看过程即可】
     *  \- -nodeps --force：忽略软件包的依赖关系，忽略软件包及文件的冲突并强行安装

*  启动docker：`systemctl enable docker --now`【加入开机自启并现在启动】  
    能正常启动且能执行`docker ps`则 安装成够。

[root@ccx ~]# systemctl enable docker --now
    Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
