1. view the system version

 

[root@localhost ~]# cat /etc/redhat-release CentOS release 6.7 (Final)

 

　　

 

Ii. Install EPEL

1. Enter the centos6 EPEL Series

http://download.fedoraproject.org/pub/epel/6/i386/repoview/epel-release.html

　　

2. wget download

[Root @ localhost ~] # Wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm--2015-09-10 17:50:49 -- getting started... 67.219.144.68, 209.132.181.16, 66.35.62.162,... connecting download.fedoraproject.org | 67.219.144.68 |: 80... connected.

3. Install EPEL with rpm (I have installed EPEL, so it is displayed that it has been installed)

[root@localhost ~]# rpm -ivh epel-release-6-8.noarch.rpmwarning: epel-release-6-8.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEYPreparing...                ########################################### [100%]package epel-release-6-8.noarch is already installed

4. After the EPEL source is installed, run the yum command to check whether it is added to the source list.

Root @ localhost ~] # Yum repolist loaded plug-ins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: Using * epel: Using 01.idc.hinet.net * extras: mirrors.163.com repository ID repository name status base CentOS-6-Base 6,575 * epel Extra Packages for Enterprise Linux 6-x86_64 11,766 extras CentOS-6-Extras 35 updates CentOS-6-Updates 298 repolist: 18,674

5. bingo, already added. Cache.

3. Disable selinux

1. View selinux status

[root@localhost ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:#     enforcing - SELinux security policy is enforced.#     permissive - SELinux prints warnings instead of enforcing.#     disabled - No SELinux policy is loaded.SELINUX=enforcing# SELINUXTYPE= can take one of these two values:#     targeted - Targeted processes are protected,#     mls - Multi Level Security protection.SELINUXTYPE=targeted 

 

2. modify the configuration file to replace enforcing with disabled.

[root@localhost ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:#     enforcing - SELinux security policy is enforced.#     permissive - SELinux prints warnings instead of enforcing.#     disabled - No SELinux policy is loaded.SELINUX=disabled# SELINUXTYPE= can take one of these two values:#     targeted - Targeted processes are protected,#     mls - Multi Level Security protection.SELINUXTYPE=targeted 

3. restart the system for reboot to take effect.

4. Be ready to install docker-io.

Note:

I have not upgraded the system kernel here.

[root@localhost ~]# uname -r2.6.32-573.3.1.el6.x86_64

According to the official docker documentation, at least 3.8 of Linux kernel is required.

When running docker in the daemon mode on a new terminal, there will be warning

[root@localhost ~]# docker -dWARN[0000] You are running linux kernel version 2.6.32-573.3.1.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.10.0. 

However, it indicates that I can use it normally.
