升级docker至最新版本

1.查找主机上关于Docker的软件包

[root@pre1 ~]# rpm -qa | grep docker

docker-1.13.1-88.git07f3374.el7.centos.x86_64

docker-common-1.13.1-88.git07f3374.el7.centos.x86_64

docker-client-1.13.1-88.git07f3374.el7.centos.x86_64

2.使用yum remove卸载软件

[root@pre1 ~]# yum remove -y docker-1.13.1-88.git07f3374.el7.centos.x86_64

[root@pre1 ~]# yum remove –y docker-common-1.13.1-88.git07f3374.el7.centos.x86_64

[root@pre1 ~]# yum remove -y docker-client-1.13.1-88.git07f3374.el7.centos.x86_64

在使用docker命令会提示docker不存在

[root@pre1 ~]# docker version

-bash: /usr/bin/docker: No such file or directory

3.使用curl升级到最新版

[root@pre1 ~]# curl -fsSL https://get.docker.com/ | sh

# Executing docker install script, commit: 2f4ae48

+ sh -c 'yum install -y -q yum-utils'

Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

+ sh -c 'yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo'

…

+ sh -c 'yum install -y -q docker-ce'

If you would like to use Docker as a non-root user, you should now consider

adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user 

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.

4.查看一下安装的版本

[root@pre1 ~]# docker version

Client:

 Version:           18.09.6

 API version:       1.39

 Go version:        go1.10.8

 Git commit:        481bc77156

 Built:             Sat May  4 02:34:58 2019

 OS/Arch:           linux/amd64

 Experimental:      false

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

5.启动docker

[root@pre1 ~]# systemctl start docker.service

6.加入开机自启动

[root@pre1 ~]# systemctl enable docker

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

7.查看Docker系统信息
