记录几个有用的网站1：http://segmentfault.com/a/1190000000366923 2：http://yuedu.baidu.com/ebook/d817967416fc700abb68fca1?pn=8&pa=1 3：http://wenku.baidu.com/link?url=AdAOMEMdzjc1BmHEBe_gXE0rKqIh_lgfheUDKNljYA7eJv-HPbdx-Oq4XghEErzBa5aPqwzOGh-sVvId0WlxU9oLyRbqm-Op1GS8gz5NFFq Docker安装笔记
一、禁用selinux由于Selinux和LXC有冲突,所以需要禁用selinux.编辑/etc/selinux/config,设置两个关键变量. SELINUX=disabledSELINUXTYPE=targeted
二、安装Fedora EPEL源yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpmr 或者: #pm -ivh ./epel-release-6-8.noarch.rpm
三、添加hop5.repo源cd /etc/yum.repos.d wget http://www.hop5.in/yum/el6/hop5.repo 或者: # cp ./hop5.repo /etc/yum.repos.d
四、安装Docker
yum安装
[X] 升级带aufs模块的3.10内核((可选)(这个步骤我没做)yum install kernel-ml-aufs kernel-ml-aufs-devel
安装docker（做了）yum install redhat-lsb yum install iptables chkconfig ip6tables offchkconfig iptables offservice ip6tables stop service iptables stop yum install device-mapper-libs yum install libcgroup* yum install docker-io
如果报错（实际安装中没有报错）: 解决办法是编辑/etc/yum.repos.d/epel.repo，把基础的恢复，镜像的地址注释掉#baseurlmirrorlist 改成 baseurl#mirrorlist然后执行: yum clean all ``` ============================================================================================================================================================================================================================================= Package Arch Version Repository Size =============================================================================================================================================================================================================================================Installing: docker-io x86_64 1.2.0-3.el6 epel 4.2 MInstalling for dependencies: 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 1.0.6-1.el6 epel 15 k lxc x86_64 1.0.6-1.el6 epel 120 k lxc-libs x86_64 1.0.6-1.el6 epel 248 kTransaction Summary =============================================================================================================================================================================================================================================Install 6 Package(s) Downloading Packages: (1/6): docker-io-1.2.0-3.el6.x86_64.rpm | 4.2 MB 00:02 (2/6): lua-alt-getopt-0.7.0-1.el6.noarch.rpm | 6.9 kB 00:00 (3/6): lua-filesystem-1.4.2-1.el6.x86_64.rpm | 24 kB 00:00 (4/6): lua-lxc-1.0.6-1.el6.x86_64.rpm | 15 kB 00:00 (5/6): lxc-1.0.6-1.el6.x86_64.rpm | 120 kB 00:00(6/6): lxc-libs-1.0.6-1.el6.x86_64.rpm | 248 kB 00:00 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
rpm手工安装:（没做....）先执行 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 再执行 rpm -ivh ./lxc-libs-1.0.6-1.el6.x86_64.rpmrpm -ivh ./lua-alt-getopt-0.7.0-1.el6.noarch.rpmrpm -ivh ./lua-filesystem-1.4.2-1.el6.x86_64.rpmrpm -ivh ./lua-lxc-1.0.6-1.el6.x86_64.rpmrpm -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.rpmrpm -ivh ./docker-io-1.3.2-2.el6.x86_64.rpm
五、初步验证docker
输入 # 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
六 、启动docker服务:service docker start#docker -d -H unix:///var/run/docker.sock
下载镜像：docker pull fedora:latest下载成功后执行了 docker run -i -t fedora /bin/bash 进入到了容器，执行了一下exit整个终端（putty）就关闭了，目前正在找客服。
[X] 七 、查找映象（没做）:
[X] 八 、进入 Docker 容器（没做）:
创建
#!/bin/shif [ -e $(dirname "$0")/nsenter ]; then
# with boot2docker, nsenter is not in the PATH but it is in the same folder
NSENTER=$(dirname "$0")/nsenterelse
NSENTER=nsenterfiif [ -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" $OPTS env --ignore-environment -- "$@"
fifi
加上可执行
[X] 附录:低版本的Redhat(6.3)可能要手动挂载cgroup（没做）我们首选禁用cgroup对应服务cgconfig. service cgconfig stop # 关闭服务 chkconfig cgconfig off # 取消开机启动 然后挂载cgroup,可以命令行挂载 mount -t cgroup none /cgroup #仅本次有效
或者修改配置文件,编辑 none /cgroup cgroup defaults 0 0 (责任编辑：IT) |
