自定义centos

1 修改 rootfs.img

1.安装工具
[root@localhost ~]# yum install -y squashfs-tools
2.用unsuqashfs命令直接解压缩squashfs.img
[root@localhost ~]# unsquashfs squashfs.img
3.挂载文件系统
[root@localhost ~]# cd squashfs-root/LiveOS/
[root@localhost LiveOS]# mount rootfs.img /mnt/rootfs/
[root@localhost LiveOS]# ls /mnt/rootfs/
bin  boot  dev  etc  firmware  lib  lib64  lost+found  mnt  modules  proc  root  run  sbin  sys  tmp  usr  var
4.根据需要可以修改/mnt/rootfs目录下文件
5.修改后重新打包
[root@localhost ~]# mksquashfs squashfs-root/ squashfs.img -comp xz -Xbcj x86 -e boot

2 创建rpm包

rpmdev-setuptree
mkdir -p BUILDROOT/hequan-1.0-1.1.x86_64

[root@test SPECS]# cat temp.spec

cp -r --parents /usr/local/hequan/*  BUILDROOT/hequan-1.0-1.1.x86_64/
cd SPECS/
rpmbuild -bb temp.spec
