CentOS7 下 Docker 安装、启动
发布于: 2020 年 08 月 12 日
1、检查系统内核
Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。
通过 uname -r 命令查看你当前的内核版本。
[xcbeyond@docker ~]$ uname -r3.10.0-327.10.1.el7.x86_
2、安装Docker
安装过程及其坎坷，出现了各种问题，并进行记录整个过程，与大家进行分享。2.1 节记录安装过程中出现的各种问题，2.2节整理的是安装成功过程，作为正常安装步骤。
2.1 安装失败
（1）Docker 软件包和依赖包已经包含在默认的 CentOS-Extras 软件源里。执行命令yum install docker
安装过程如下：
[xcbeyond@docker etc]$ sudo yum install dockerLoaded plugins: fastestmirror, langpacksbase | 3.6 kB 00:00:00 docker-ce-stable | 2.9 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 docker-ce-stable/x86_64/primar FAILED https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/repodata/251ca0bf128072f68c0ccae90067d231841488501814e0b0b6f492c17c069daa-primary.sqlite.bz2: [Errno 14] curl#60 - "Peer's Certificate issuer is not recognized."Trying other mirror.It was impossible to connect to the CentOS servers.This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,or a transparent proxy that tampers with TLS security, or an incorrect system clock.You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errorsIf above article doesn't help to resolve this issue please use https://bugs.centos.org/.

（2）查看Docker版本。执行命令docker version
[xcbeyond@docker etc]$ docker versionClient: Version: 1.13.1 API version: 1.26 Package version: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
(3)启动Docker。执行命令 service docker start.
[xcbeyond@docker ~]$ sudo service docker startRedirecting to /bin/systemctl start docker.serviceJob for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
哎，启动失败了。查看下docker状态，如下所示：
[xcbeyond@docker ~]$ systemctl status docker● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Wed 2018-08-29 23:07:19 CST; 1min 13s ago Docs: http://docs.docker.com Process: 18527 ExecStart=/usr/bin/dockerd-current --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current --default-runtime=docker-runc --exec-opt native.cgroupdriver=systemd --userland-proxy-path=/usr/libexec/docker/docker-proxy-current --init-path=/usr/libexec/docker/docker-init-current --seccomp-profile=/etc/docker/seccomp.json $OPTIONS $DOCKER_STORAGE_OPTIONS $DOCKER_NETWORK_OPTIONS $ADD_REGISTRY $BLOCK_REGISTRY $INSECURE_REGISTRY $REGISTRIES (code=exited, status=1/FAILURE) Main PID: 18527 (code=exited, status=1/FAILURE) Aug 29 23:07:17 docker systemd[1]: Starting Docker Application Container Engine...Aug 29 23:07:18 docker dockerd-current[18527]: time="2018-08-29T23:07:18.066916004+...d"Aug 29 23:07:18 docker dockerd-current[18527]: time="2018-08-29T23:07:18.071982389+...1"Aug 29 23:07:19 docker dockerd-current[18527]: time="2018-08-29T23:07:19.085154395+08...Aug 29 23:07:19 docker dockerd-current[18527]: Error starting daemon: SELinux is no...e)Aug 29 23:07:19 docker systemd[1]: docker.service: main process exited, code=exite...UREAug 29 23:07:19 docker systemd[1]: Failed to start Docker Application Container Engine.Aug 29 23:07:19 docker systemd[1]: Unit docker.service entered failed state.Aug 29 23:07:19 docker systemd[1]: docker.service failed.Hint: Some lines were ellipsized, use -l to show in full.
网上查阅了大量资料，进行配置的修改等，尝试都未能解决，最终决定还是卸载掉，重新换种方式来安装吧。
2.2 安装成功
（1）卸载docker，并配置docker.repo，如下所示：
[xcbeyond@docker run]$ sudo yum remove docker……[xcbeyond@docker run]$ sudo yum remove docker-selinux……[xcbeyond@docker run]$ sudo vi /etc/yum.repos.d/docker.repo[dockerrepo]name=Docker Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/enabled=1gpgcheck=1gpgkey=https://yum.dockerproject.org/gpg
（2）安装docker，执行命令yum install docker-engine，如下所示：
（如失败，则可多执行几次便可。安装过程，因需下载安装包，请耐心等待）

（3）启动docker。执行命令systemctl start docker，如下所示：
[xcbeyond@docker run]$ sudo systemctl start docker
哈哈，大功告成，终于安装成功啦。睡觉喽！
如果在检索镜像时，出现如下类似错误：
[docker@docker xcbeyond]$ docker search redisError response from daemon: Get https://index.docker.io/v1/search?q=redis&n=25: x509: certificate signed by unknown authority
这是由于无法访问国外docker镜像仓库的原因，或者访问比较慢，可修改为国内docker仓库。docker在中国已经有了仓库：https://www.docker-cn.com/registry-mirror，访问速度还不错。
修改方法：
（如果没有daemon.json文件，则创建）
[docker@docker xcbeyond]$ sudo vi /etc/docker/daemon.json{ "registry-mirrors": ["https://registry.docker-cn.com"]}
重启docker，就可以了。
