不得不说国内的墙真是太厉害了，好的不好的都给你屏蔽了，这难道不是另外一种形式的闭关锁国？
无形中增加技术人员的难度，这不是为难我胖虎么？

配置国内dnf

1、dnf清除配置

[code lang=”shell”]dnf clean all[/code]

2、备份原dnf配置

[code lang=”shell”]mv /etc/yum.repos.d /etc/yum.repos.d.bak[/code]

3、创建新的dnf配置

[code lang=”shell”]mkdir /etc/yum.repos.d

cd /etc/yum.repos.d

vim CentOS-Base.repo[/code]输入如下内容并保存

[code lang=”shell”]

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

4、重新生成dnf缓存

[code lang=”shell”]dnf makecache[/code]至此dnf配置已经完成

安装yum工具配置国内镜像仓库

1、安转yum工具

[code lang=”shell”]yum install -y yum-utils[/code]

2、配置国内镜像仓库

[code lang=”shell”]yum-config-manager –add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo[/code]

安装docker

1、安装docker

[code lang=”shell”]docker-ce –nobest[/code]

2、配置docker国内国内镜像仓库地址

2.1、进入docker配置文件目录，没有则创建。

[code lang=”shell”]cd /etc/docker[/code]

2.2、编辑配置文件，没有则创建

[code lang=”shell”]vim daemon.json[/code]输入如下内容并保存，其中指定了国内镜像加速地址和容器存放数据目录，这里建议修改成数据盘挂载目录。

[code lang=”shell”]{
"registry-mirrors": ["https://nsybtd8u.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.1.54:8000"],
"data-root":"/home/docker"
}[/code]

启动docker

[code lang=”shell”]systemctl enable docker

systemctl start docker[/code]

安装docker-compose

1、下载

[code lang=”shell”]sudo curl -L "https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose[/code]

2、授权

[code lang=”shell”]sudo chmod +x /usr/local/bin/docker-compose[/code]

3、验证

[code lang=”shell”]docker-compose –version[/code]
