centos源码编译docker，centos源码docker

安装golang centos7 直接安装golang

yum install golang

centos6需添加软件源，然后再安装

rpm -ivh http://ftp.riken.jp/Linux/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
yum install golang

安装依赖包

yum groupinstall 'Development tools'
yum install glibc-static ?sqlite-devel.x86_64 libselinux-static libsepol-static
yum install libuuid-devel libattr-devel zlib-devel libacl-devel e2fsprogs-devel libblkid-devel lzo-devel  asciidoc xmlto

编译device mapper

git clone --no-checkout https://git.fedorahosted.org/git/lvm2.git /usr/local/lvm2 && cd /usr/local/lvm2 && git checkout -q v2_02_103  
#如果下载超时，使用https://github.com/steven676/lvm2.git代替，或直接从https://git.fedorahosted.org/cgit/lvm2.git/refs/tags下载
cd /usr/local/lvm2 && ./configure --enable-static_link && make  && make install

此处要注意别用./configure --enable-static_link && make device-mapper && make install_device-mapper只编译device mapper，这样有可能因为lvm与device mapper不匹配，而导致lvm无法运行，在物理机下次重启时，所有lvm文件系统都不可用，只能重装操作系统了。

编译安装sqlite

wget http://www.sqlite.org/2015/sqlite-autoconf-3080803.tar.gz
./configure
make
make install

安装btrfs-progs centos7

yum install btrfs-progs

centos6

git clone git://git.kernel.org/pub/scm/linux/kernel/git/kdave/btrfs-progs.git 
cd btrfs-progs
./autogen.sh 
./configure
make
make install

设置环境变量

export GOPATH=/path/to/go   #docker目录放在/path/to/go/docker
export AUTO_GOPATH=1

编译docker
静态编译

 ./hack/make.sh binary

动态编译docker

./hack/make.sh dynbinary

TroubleShooting

•  执行lvm --version出错：

lvm: relocation error: lvm: symbol dm_get_status_cache, version Base not defined in file libdevmapper.so.1.02 with link time reference
这是由于之更新了device mapper，没有更新lvm导致，直接运行：

cd /usr/local/lvm2 && ./configure --enable-udev_sync && make && make install

• 启动docker时报如下警告

 level="warning" msg="WARNING: Udev sync is not supported. This will lead to unexpected behavior, data loss and errors"
原因在于编译device mapper时没有添加对 udev sync的支持，执行如下命令重新编译：

yum install libudev-devel
cd /usr/local/lvm2 && ./configure --enable-udev_sync && make && make install
cd docker && ./hack/make.sh dynbinary  

由于现在udev没有可用静态库，所以只能编译device mapper的动态链接库，也就只能编译动态链接版的docker。

• centos7编译device mapper出错，错误信息如下，未解决，求助？
