CentOS6.X下Docker如何安裝

小編給大家分享一下CentOS6.X下Docker如何安裝，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

專注于為中小企業(yè)提供成都做網(wǎng)站、網(wǎng)站制作服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)徐匯免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了上1000家企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過(guò)網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

[X] 一、禁用selinux

由于Selinux和LXC有沖突,所以需要禁用selinux.編輯/etc/selinux/config,設(shè)置兩個(gè)關(guān)鍵變量.

SELINUX=disabled
SELINUXTYPE=targeted
[X] 二、安裝Fedora EPEL源
rpm -ivh ./epel-release-6-8.noarch.rpm  
或者:  
#yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
[X] 三、添加hop5.repo源
cp ./hop5.repo /etc/yum.repos.d        
或者:  
#cd /etc/yum.repos.d        
#wget http://www.hop5.in/yum/el6/hop5.repo
[X] 四、安裝Docker
yum安裝
[X] 升級(jí)帶aufs模塊的3.10內(nèi)核((可選)
yum install kernel-ml-aufs kernel-ml-aufs-devel

  1. 修改grub的主配置文件/etc/grub.conf，設(shè)置default=0，表示第一個(gè)title下的內(nèi)容為默認(rèn)啟動(dòng)的kernel（一般新安裝的內(nèi)核在第一個(gè)位置）。

  2. 重啟系統(tǒng)reboot now,

  3. 然后執(zhí)行uname -r,查看是否已經(jīng)是3.10內(nèi)核!

[root@localhost ~]# uname -r
3.10.5-3.el6.x86_64

  1. 執(zhí)行grep aufs /proc/filesystems,查看內(nèi)核是否支持aufs!

[root@localhost ~]# grep aufs /proc/filesystems
nodev aufs

[X] 安裝docker
yum install redhat-lsb

yum install iptables
chkconfig ip6tables off
chkconfig iptables off
service ip6tables stop
service iptables stop

yum install device-mapper-libs
yum install libcgroup*
yum install docker-io

如果報(bào)錯(cuò):Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

解決辦法是編輯/etc/yum.repos.d/epel.repo，把基礎(chǔ)的恢復(fù)，鏡像的地址注釋掉

#baseurl
mirrorlist

改成

baseurl
#mirrorlist

然后執(zhí)行: yum clean all

rpm手工安裝:

先執(zhí)行

rpm --nodeps -ev $(rpm -qa | grep -i 'device-mapper-libs-')
rpm --nodeps -ev $(rpm -qa | grep -i 'device-mapper-')
rpm --nodeps -ev $(rpm -qa | grep -i 'device-mapper-event-libs-')
rpm --nodeps -ev $(rpm -qa | grep -i 'device-mapper-event-')

rpm -ivh ./device-mapper-event-1.02.90-2.el6.x86_64.rpm ./device-mapper-event-libs-1.02.90-2.el6.x86_64.rpm ./device-mapper-1.02.90-2.el6.x86_64.rpm ./device-mapper-libs-1.02.90-2.el6.x86_64.rpm

再執(zhí)行

rpm -ivh ./lxc-libs-1.0.6-1.el6.x86_64.rpm
rpm -ivh ./lua-alt-getopt-0.7.0-1.el6.noarch.rpm
rpm -ivh ./lua-filesystem-1.4.2-1.el6.x86_64.rpm
rpm -ivh ./lua-lxc-1.0.6-1.el6.x86_64.rpm
rpm -ivh ./lxc-1.0.6-1.el6.x86_64.rpm
#6.4版本以下需要 rpm -ivh ./libcgroup-0.40.rc1-5.el6.x86_64.rpm
rpm -ivh ./docker-io-1.3.2-2.el6.x86_64.rpm
[X] 五、初步驗(yàn)證docker

輸入docker -h,如果有如下輸出,就證明docker在形式上已經(jīng)安裝成功.

# docker -h 
Usage of docker: 
  -D=false: Enable debug mode 
  -H=[]: Multiple tcp://host:port or unix://path/to/socket to bind in daemon mode, single connection otherwise 
  -api-enable-cors=false: Enable CORS headers in the remote API 
  -b="": Attach containers to a pre-existing network bridge; use 'none' to disable container networking
  -bip="": Use this CIDR notation address for the network bridge's IP, not compatible with -b 
  -d=false: Enable daemon mode 
  -DNS=[]: Force docker to use specific DNS servers 
  -g="/var/lib/docker": Path to use as the root of the docker runtime 
  -icc=true: Enable inter-container communication 
  -ip="0.0.0.0": Default IP address to use when binding container ports 
  -iptables=true: Disable docker's addition of iptables rules 
  -p="/var/run/docker.pid": Path to use for daemon PID file
  -r=true: Restart previously running containers 
  -s="": Force the docker runtime to use a specific storage driver 
  -v=false: Print version information and quit
[X] 六 、啟動(dòng)docker服務(wù):
service docker start
#docker -d -H unix:///var/run/docker.sock
[X] 七 、查找映象:

docker search 映象名字 從index.docker.io搜尋所需鏡像. 去https://index.docker.io獲取鏡像相關(guān)的信息.

[X] 八 、進(jìn)入 Docker 容器:

創(chuàng)建vi /bin/docker-enter.sh

#!/bin/sh

if [ -e $(dirname "$0")/nsenter ]; then
  # with boot2docker, nsenter is not in the PATH but it is in the same folder
  NSENTER=$(dirname "$0")/nsenter
else
  NSENTER=nsenter
fi

if [ -z "$1" ]; then
  echo "Usage: `basename "$0"` CONTAINER [COMMAND [ARG]...]"
  echo ""
  echo "Enters the Docker CONTAINER and executes the specified COMMAND."
  echo "If COMMAND is not specified, runs an interactive shell in CONTAINER."
else
  PID=$(docker inspect --format "{{.State.Pid}}" "$1")
  if [ -z "$PID" ]; then
    exit 1
  fi
  shift

  OPTS="--target $PID --mount --uts --ipc --net --pid --"

  if [ -z "$1" ]; then
    # No command given.
    # Use su to clear all host environment variables except for TERM,
    # initialize the environment variables HOME, SHELL, USER, LOGNAME, PATH,
    # and start a login shell.
    "$NSENTER" $OPTS su - root
  else
    # Use env to clear all host environment variables.
    "$NSENTER" $OPTS env --ignore-environment -- "$@"
  fi
fi

加上可執(zhí)行chmod +x /bin/docker-enter.sh 運(yùn)行docker-enter.sh <container id>,這樣就進(jìn)入到指定的容器中!

[X] 附錄:低版本的Redhat(6.3)可能要手動(dòng)掛載cgroup

我們首選禁用cgroup對(duì)應(yīng)服務(wù)cgconfig.

  service cgconfig stop # 關(guān)閉服務(wù) 
  chkconfig cgconfig off # 取消開(kāi)機(jī)啟動(dòng)

然后掛載cgroup,可以命令行掛載

  mount -t cgroup none /cgroup  #僅本次有效

或者修改配置文件,編輯/etc/fstab,加入

none                    /cgroup                 cgroup  defaults        0 0
