打包辅助工具

实际开发过程中必须模拟用户的环境或是构建一个“干净”的环境（一个仅仅满足编译构建的最小系统环境）使用mock命令就达到在一个“干净”的环境重新编译构建。

• 安装软件包： yum install mock -y

YUM仓库的配置

使用 mock 工具编译软件包，需要在yum仓库中建立了一个sysbuild分组，该分组包含了一个最小化系统所需的基础软件包。以下是 comps.xml 参考：

mock工具的配置

根据需要修改默认配置 /etc/mock/default.cfg，配置文件中config_opts['chroot_setup_cmd'] = 'install @sysbuild' 分组名称sysbuild需要和仓库配置保持一致，参考配置如下：

config_opts['root'] = 'deepin-15-x86_64'
config_opts['target_arch'] = 'x86_64'
config_opts['legal_host_arches'] = ('x86_64',)
config_opts['chroot_setup_cmd'] = 'install @sysbuild'
config_opts['dist'] = 'deepin15'  # only useful for --resultdir variable subst
config_opts['yum.conf'] = """
[main]
keepcache=1
debuglevel=2
reposdir=/dev/null
logfile=/var/log/yum.log
retries=20
obsoletes=1
gpgcheck=0
assumeyes=1
syslog_ident=mock
syslog_device=
mdpolicy=group:primary
best=1

# repos
[deepin]
name=deepin server enterprise linux repo - amd64 
baseurl=http://10.1.10.21/server-dev/dsee-15-amd64/main/ 
enabled=1 
gpgcheck=0 
"""

mock的基本使用

一切准备就绪，开始使用mock 重新编译一个软件包。

• mock --init
• mock --rebuild pkg.src.rpm

小技巧：使用mock编译辅助脚本，并行编译软件包

#！/bin/bash
pkg=$1

cat > /etc/mock/$1.cfg <<EOF
config_opts['dist'] = 'deepin15'
config_opts['root'] = '$pkg'
config_opts['target_arch'] = 'x86_64'
config_opts['legal_host_arches'] = ('x86_64',)
config_opts['chroot_setup_cmd'] = 'install @buildsys-build'
config_opts['yum.conf'] = """
