Chroot 环境打包利器 Mock(安装和简单应用)

Mock – Chroot Build Tools
Mock creates chroots and builds packages in them. Its only task is to reliably populate a chroot and attempt to build a package in that chroot.
更多信息请查看Wiki
一.安装
最简单的安装方法(yum ) 因为是Fedora发行的包,yum中不一定有.如果没有请安装epel或rpmforge源.安装方法不介绍
yum -y install mock

mock 为了安全,不能使用root用户,所以添加一个新的用户,并指定组为mock
useradd bulid -G mock
查看用户组
cat /etc/group|grep mock
mock:x:489:bulid
切换到bulid 用户.开始我们的打包操作
su bulid

2.应用
先介绍一个配置文件

初始化chroot配置环境
mock –init -r fedora-10-i386
提示如下:——->原因是没有指定路径

[bulid@builder mock]$ /usr/bin/mock –init -r fedora-15-i386
INFO: mock.py version 1.1.9 starting…
State Changed: init plugins

完成初始化.

/usr/bin/mock –shell -r fedora-15-i386
mock-chroot> chmod u+s bin/bash
/var/lib/mock/fedora-15-i386/root/bin/bash -p
cat /etc/shadow

把src.rpm 编译为指定平台
/usr/bin/mock -v -r epel-5-x86_64 –no-clean mtr-0.71-3.1.src.rpm
安装指定的包到chroot环境中
/usr/bin/mock –install -r epel-5-x86_64 /var/lib/mock/epel-5-x86_64/result/wget-1.11.4-2.el5.1.x8
