通过定制nginx的rpm包学习如何制作rpm安装包

      RPM是RedHat Package Manager(RedHat软件包管理工具)的缩写,是一种用于互联网下载包的打包及安装工具,它包含在某些Linux分发版中。它生成具有.RPM扩展名的文件。使用rpm安装软件和管理软件非常的方便。

1.安装rpm-build

#yum -y install rpm-build redhat-rpm-config

2.建立目录结构

#mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
# tree -n ~/rpmbuild/
/root/rpmbuild/
├── BUILD        存放源代码
├── RPMS         存放用于管理rpm制作进程的spec文件
├── SOURCES      解压后的文件存放在这里
├── SPECS        存放由rpmbuild制作好的二进制包
└── SRPMS        存放由rpmbuild制作好的源码包
5 directories, 0 files

3.下载源码包

将nginx、nginx-rtmp-module放在SOURCE目录下

SOURCES]# ll
总用量 71320
-rw-r--r--.  1 root root 69195965 8月  15 09:09 nginx-1.15.3.tar.gz
-rw-r--r--.  1 root root     4876 8月  15 09:59 nginx.conf-rw-r--r--.  1 root root  3821160 8月  14 16:39 nginx-rtmp-module.tar.gz

4.制作.spec文件

在SPECS下执行:vim nginx.spec

# cat nginx.spec
Name: nginx
Version: 1.15.3
Release: 1%{?dist}

5.spec文件解释

#:以#开头是注释,rpm会忽略它。
Summary:   简单描述软件。
Name :    定义rpm的名称。
Version:   定义软件版本
Release:   发行版本
License:   定义许可证
Group:    软件分类
Source:   源码下载地址
URL:      源码相关网站
Distribution: 发行版系列
Packager: 打包人的信息
%description:软件详细描述,可多行
%prep :软件编译之前的处理,如解压。
%build :开始编译软件,如make
%install :开始安装软件,如make install
%files :指定哪些文件需要被打包,如/usr/local/nginx
%preun :定义卸载之前的动作,如杀掉进程。
这里只介绍了几个常用的tag,更详细的请参考:http://www.rpm.org/max-rpm/ch-rpm-inside.html

6.开始RPM制作

# rpmbuild -bb nginx.spec
rpmbuild -bp nginx.spec 制作到%prep段
rpmbuild -bc nginx.spec 制作到%build段
rpmbuild -bi nginx.spec 执行 spec 文件的 "%install" 阶段 (在执行了 %prep 和 %build 阶段之后)。这通常等价于执行了一次 "make install"
rpmbuild -bb nginx.spec 制作二进制包
rpmbuild -ba nginx.spec 表示既制作二进制包又制作src格式包

以下未验证

9.生成密钥并验证

9.1.使用gpg方式生成签名密钥

# gpg --gen-key
Your selection?1<Enter>  #默认即可
What keysize do you want? (2048) 1024<Enter>  #选择密钥长度
Key is valid for? (0) 1y<Enter>  #有效期
Is this correct? (y/N) y<Enter>  #确认
Real name: nmshuishui<Enter>  #密钥名称
Email address: 353025240@qq.com<Enter>  #邮件
Comment: GPG-RPM-KEY<Enter>  #备注
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O<ENTER> #okay确认
Enter passphrase  OK <Enter>  #按Enter输入密码                    
<Take this one anyway> <Enter> #确认使用此密码
#####
在生成密钥的时候,会报这么一个信息:can't connect to `/root/.gnupg/S.gpg-agent': No such file or directory,可以不用理会它。
接下来就是一些随机数的说明了:We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
就狂敲键盘和移动鼠标吧,也可以链接一个伪随机数(不过不安全),接下来的活儿就是等了
生成密钥后会是这样的:
gpg: checking the trustdb
gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
pub   2048R/DF63EDFB 2014-11-26
      Key fingerprint = 338D 476F 29C9 E2D6 6604  1D96 6F73 1E81 DF63 EDFB
uid                  nmshuishui (gen-key) <353025240@qq.com>
sub   2048R/263FB359 2014-11-26

9.2.查看生成的密钥

# gpg --list-keys
/root/.gnupg/pubring.gpg
------------------------
pub   2048R/DF63EDFB 2014-11-26
uid                  nmshuishui (gen-key) <353025240@qq.com>
sub   2048R/263FB359 2014-11-26

9.3.导出公钥以供验证

# gpg --export -a "nmshuishui" > RPM-GPG-KEY-nmshuishui

9.4.在~/.rpmmacros宏中定义加密密钥

# vim ~/.rpmmacros
%_gpg_name nmshuishui

9.5.为rpm包签名

# rpm --addsign /home/hero/rpmbuild/RPMS/x86_64/nginx-1.7.7-3.el6.x86_64.rpm 
Enter pass phrase: 
Pass phrase is good.
/home/hero/rpmbuild/RPMS/x86_64/nginx-1.7.7-3.el6.x86_64.rpm:

9.6.将公钥导入rpm包

# rpm --import RPM-GPG-KEY-nmshuishui

9.7.验证

# rpm --checksig /home/hero/rpmbuild/RPMS/x86_64/nginx-1.7.7-3.el6.x86_64.rpm
/home/hero/rpmbuild/RPMS/x86_64/nginx-1.7.7-3.el6.x86_64.rpm: rsa sha1 (md5) pgp md5 OK

9.8.重新安装nginx,验证安装包的签名信息

# rpm -ivh /home/hero/rpmbuild/RPMS/x86_64/nginx-1.7.7-3.el6.x86_64.rpm
