centos6.7 安裝Docker，centos6.7docker

centos6.7 安裝Docker，centos6.7docker
 一、查看系統版本

 

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

 

　　

 

二、安裝EPEL

1.進入centos6系列EPEL

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

　　

2. wget下載

[root@localhost ~]# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm--2015-09-10 17:50:49--  http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm正在解析主機 download.fedoraproject.org... 67.219.144.68, 209.132.181.16, 66.35.62.162, ...正在串連 download.fedoraproject.org|67.219.144.68|:80... 已串連。已發出 HTTP 要求，正在等待回應... 302 Found位置：http://mirrors.opencas.cn/epel/6/i386/epel-release-6-8.noarch.rpm [跟隨至新的 URL]--2015-09-10 17:50:50--  http://mirrors.opencas.cn/epel/6/i386/epel-release-6-8.noarch.rpm正在解析主機 mirrors.opencas.cn... 159.226.11.160, 2001:cc0:2004:1:225:90ff:fe00:fe8b, 2001:cc0:2004:1:225:90ff:fe3a:e6b5正在串連 mirrors.opencas.cn|159.226.11.160|:80... 已串連。已發出 HTTP 要求，正在等待回應... 200 OK長度：14540 (14K) [application/x-redhat-package-manager]正在儲存至: “epel-release-6-8.noarch.rpm”100%[=======================================================================================================>] 14,540      12.9K/s   in 1.1s    2015-09-10 17:50:56 (12.9 KB/s) - 已儲存 “epel-release-6-8.noarch.rpm” [14540/14540])

3.rpm安裝EPEL(我已經安裝過了，所以顯示已經安裝了)

[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.安裝好EPEL 源後，用yum 命令來檢查是否添加到源列表

root@localhost ~]#  yum repolist已載入外掛程式：fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * epel: mirror01.idc.hinet.net * extras: mirrors.163.com * updates: mirrors.163.com倉庫標識                                          倉庫名稱                                                                                 狀態base                                              CentOS-6 - Base                                                                           6,575*epel                                             Extra Packages for Enterprise Linux 6 - x86_64                                           11,766extras                                            CentOS-6 - Extras                                                                            35updates                                           CentOS-6 - Updates                                                                          298repolist: 18,674

5.bingo，已經添加。進行緩衝。

[root@localhost ~]# yum makecache已載入外掛程式：fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfileCould not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64 error was12: Timeout on https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64: (28, 'Operation too slow.

三、禁用selinux

1.查看selinux狀態

[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.修改該設定檔中將enforcing替換為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.reboot重啟一下系統，使生效。

四、準備就緒，安裝docker-io，摸摸噠。

[root@localhost ~]# yum install docker-io已載入外掛程式：fastestmirror, refresh-packagekit, security設定安裝進程Loading mirror speeds from cached hostfile * base: mirrors.hust.edu.cn * epel: ftp.cuhk.edu.hk * extras: mirrors.163.com * updates: mirrors.163.com解決依賴關係--> 執行事務檢查---> Package docker-io.x86_64 0:1.7.1-2.el6 will be 安裝--> 處理依賴關係 lxc，它被軟體包 docker-io-1.7.1-2.el6.x86_64 需要--> 處理依賴關係 libcgroup，它被軟體包 docker-io-1.7.1-2.el6.x86_64 需要--> 執行事務檢查---> Package libcgroup.x86_64 0:0.40.rc1-16.el6 will be 安裝---> Package lxc.x86_64 0:1.0.7-2.el6 will be 安裝--> 處理依賴關係 lua-lxc(x86-64) = 1.0.7-2.el6，它被軟體包 lxc-1.0.7-2.el6.x86_64 需要--> 處理依賴關係 lua-alt-getopt，它被軟體包 lxc-1.0.7-2.el6.x86_64 需要--> 處理依賴關係 liblxc.so.1()(64bit)，它被軟體包 lxc-1.0.7-2.el6.x86_64 需要--> 執行事務檢查---> Package lua-alt-getopt.noarch 0:0.7.0-1.el6 will be 安裝---> Package lua-lxc.x86_64 0:1.0.7-2.el6 will be 安裝--> 處理依賴關係 lua-filesystem，它被軟體包 lua-lxc-1.0.7-2.el6.x86_64 需要---> Package lxc-libs.x86_64 0:1.0.7-2.el6 will be 安裝--> 執行事務檢查---> Package lua-filesystem.x86_64 0:1.4.2-1.el6 will be 安裝--> 完成依賴關係計算依賴關係解決================================================================================================================================================= 軟體包                                架構                          版本                                      倉庫                         大小=================================================================================================================================================正在安裝: docker-io                             x86_64                        1.7.1-2.el6                               epel                        4.6 M為依賴而安裝: libcgroup                             x86_64                        0.40.rc1-16.el6                           base                        129 k lua-alt-getopt                        noarch                        0.7.0-1.el6                               epel                        6.9 k lua-filesystem                        x86_64                        1.4.2-1.el6                               epel                         24 k lua-lxc                               x86_64                        1.0.7-2.el6                               epel                         15 k lxc                                   x86_64                        1.0.7-2.el6                               epel                        120 k lxc-libs                              x86_64                        1.0.7-2.el6                               epel                        250 k事務概要=================================================================================================================================================Install       7 Package(s)總下載量：5.1 MInstalled size: 20 M確定嗎？[y/N]：

還需要我解釋麼，一路y下去。

啟動我們的寶貝docker

[root@localhost ~]# /etc/init.d/docker startStarting cgconfig service:                                 [確定]Starting docker:                                   [確定]

查看docker進程

[root@localhost ~]# ps -ef | grep dockerroot       3602      1  0 18:26 pts/0    00:00:00 /usr/bin/docker -droot       3745   3429  0 18:27 pts/0    00:00:00 grep docker

查看安裝的docker版本

Status: Downloaded newer image for centos:latest[root@localhost ~]# docker versionClient version: 1.7.1Client API version: 1.19Go version (client): go1.4.2Git commit (client): 786b29d/1.7.1OS/Arch (client): linux/amd64Server version: 1.7.1Server API version: 1.19Go version (server): go1.4.2Git commit (server): 786b29d/1.7.1OS/Arch (server): linux/amd64

注意：

我在這裡並沒有升級系統核心

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

docker官方文檔說要求Linux kernel至少3.8以上。

在一個新的終端裡守護模式運行docker時，會出現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. 

但是目前表示我可以正常使用。
