centos7 build bcache-tools

获取源码

centos 本身不提供bcache-tools的rpm，所以需要自己build。
从fedora下载源码，也可以从github社区下载, 从fedora下载主要是需要spec文件,方便build rpm包.
bcache-tools-1.0.8-17.fc32.src.rpm

build

#rpm -ivh bcache-tools-1.0.8-17.fc32.src.rpm

#cd ~/rpmbuild/SPECS/

把下面的diff patch:应用到bcache-tools.spec文件

#rpmbuild -ba bcache-tools.spec

build出bcache-tools的rpm包 bcache-tools-1.0.8-17.el7.centos.x86_64

安装

安装依赖

• yum install libblkid

安装

• rpm -ivh bcache-tools-1.0.8-17.el7.centos.x86_64.rpm
  会出现下面的错误:

preparing... ################################# [100%]
file /usr/lib/dracut/modules.d/90bcache/module-setup.sh from install of bcache-tools-1.0.8-17.el7.centos.x86_64 conflicts with file from package dracut-033-502.el7.x86_64
是因为bcache-tools安装的module-setup.sh和dracut里的冲突, 直接覆盖安装即可

• rpm -ivh bcache-tools-1.0.8-17.el7.centos.x86_64.rpm --replacefiles
