本文主要包含docker,yum,源,yum安装docker,配置docker官方源等服务器相关知识,叫我蒋乐哥哥 希望可以进行参考
本文介绍了如何配置docker官方源并用yum安装docker ，分享给大家，希望对各位有帮助
一、docker的官方安装文档：
https://docs.docker.com/engine/installation/linux/centos/
由docker给的文档可以看出它也只是去配置了一个docker的yum源、然后就通过这个源来安装docker了；在这个文档下我们采用手工配置
的方式
二、配置一个docker用的源：
1、为docker 增加一个新的yum配置文件；touch /etc/yum.repos.d/docker.repo
touch /etc/yum.repos.d/docker.repo
2、docker.repo的内容如下
[docker-ce-stable] name=Docker CE Stable - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/stable enabled=1 gpgcheck=0 #我把这里设置成了0、说明我信任了这个源，不对它的rpm进行检察 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-stable-debuginfo] name=Docker CE Stable - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/stable enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-stable-source] name=Docker CE Stable - Sources baseurl=https://download.docker.com/linux/centos/7/source/stable enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge] name=Docker CE Edge - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge-debuginfo] name=Docker CE Edge - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge-source] name=Docker CE Edge - Sources baseurl=https://download.docker.com/linux/centos/7/source/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test] name=Docker CE Test - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test-debuginfo] name=Docker CE Test - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test-source] name=Docker CE Test - Sources baseurl=https://download.docker.com/linux/centos/7/source/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg
三、安装docker:
sudo yum install docker-ce Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package docker-ce.x86_64 0:17.03.1.ce-1.el7.centos will be installed --> Processing Dependency: docker-ce-selinux >= 17.03.1.ce-1.el7.centos for package: docker-ce-17.03.1.ce-1.el7.centos.x86_64 --> Running transaction check ---> Package docker-ce-selinux.noarch 0:17.03.1.ce-1.el7.centos will be installed --> Finished Dependency Resolution Dependencies Resolved ===================================================================================================================================== Package Arch Version Repository Size ===================================================================================================================================== Installing: docker-ce x86_64 17.03.1.ce-1.el7.centos docker-ce-stable 19 M Installing for dependencies: docker-ce-selinux noarch 17.03.1.ce-1.el7.centos docker-ce-stable 28 k Transaction Summary ===================================================================================================================================== Install 1 Package (+1 Dependent package) Total download size: 19 M Installed size: 19 M Is this ok [y/d/N]: y
四、直接下载rpm包的方式来安装：
1、我在安装docker的时候发现下载的速度只有3kB/s 然而文件大小有19M；就在我感觉安装无望的时候、我机智的想到了自己直接把rpm下载下来
看了下docker.repo 、发现centos7的源地址是 https://download.docker.com/linux/centos/7/$basearch/stable 所以我只要去
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
用迅雷(我是会员有加速)把rpm包下载下来就行了
下载如下文件：
docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
五、安装docker:
ll total 19096 -rwxrwxrwx 1 jianglexing jianglexing 19521288 May 30 20:05 docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm -rw-r--r-- 1 jianglexing jianglexing 29108 May 30 20:15 docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm [root@workstudio docker]# yum localinstall * Loaded plugins: fastestmirror, langpacks Examining docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm: docker-ce-17.03.0.ce-1.el7.centos.x86_64 Marking docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm to be installed Examining docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm: docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch Marking docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package docker-ce.x86_64 0:17.03.0.ce-1.el7.centos will be installed ---> Package docker-ce-selinux.noarch 0:17.03.0.ce-1.el7.centos will be installed --> Finished Dependency Resolution Dependencies Resolved ===================================================================================================================================== Package Arch Version Repository Size ===================================================================================================================================== Installing: docker-ce x86_64 17.03.0.ce-1.el7.centos /docker-ce-17.03.0.ce-1.el7.centos.x86_64 65 M docker-ce-selinux noarch 17.03.0.ce-1.el7.centos /docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch 43 k Transaction Summary ===================================================================================================================================== Install 2 Packages Total size: 65 M Installed size: 65 M Is this ok [y/d/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch 1/2 setsebool: SELinux is disabled. libsemanage.semanage_direct_install_info: Overriding docker module at lower priority 100 with module at priority 400.

六、启动docker:
[root@workstudio docker]# systemctl start docker [root@workstudio docker]# ps -ef | grep docker root 4458 1 1 20:22 ? 00:00:00 /usr/bin/dockerd root 4465 4458 0 20:22 ? 00:00:00 docker-containerd -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --metrics-interval=
