Linux 安装包结构 rpm 结构探索

问题

如何在 centos 上离线安装一个 openresty

方案

参照 OpenResty® Linux Packages( openresty.org/en/linux-packages.html) 提供。

1. 下载 openresty-1.15.8.2-6.el7.x86_64.rpm( openresty.org/package/centos/7/x86_64/openresty-1.15.8.2-6.el7.x86_64.rpm)
2. 下载 openresty-openssl-1.1.0k-3.el7.x86_64.rpm( openresty.org/package/centos/7/x86_64/openresty-openssl-1.1.0k-3.el7.x86_64.rpm)
3. 下载 openresty-zlib-1.2.11-3.el7.centos.x86_64.rpm( openresty.org/package/centos/7/x86_64/openresty-zlib-1.2.11-3.el7.centos.x86_64.rpm)
4. 下载 openresty-pcre-8.43-1.el7.x86_64.rpm( openresty.org/package/centos/7/x86_64/openresty-pcre-8.43-1.el7.x86_64.rpm)
5. 上述4个 rpm 包，上传至服务器，rpm -Uvh --force *.rpm 全部安装。
6. 更新版本，可以在 openresty repository to your CentOS system( openresty.org/package/centos/7/x86_64/) 中查找。

什么是 rpm 包？( blog.packagecloud io/eng/2015/10/13/inspect-extract-contents-rpm-packages/)

RPM originally stands for Red Hat Package Manager.( e7z 组织网/open-rpm.htm)

An RPM package is simply a header structure on top of a CPIO archive. The package itself is comprised of four sections: a header with a leading identifier (magic number) that identifies the file as an RPM package, a signature to verify the integrity of the package, the header or ‘tagged’ data containing package information, version numbers, and copyright messaging, and the archive containing the actual program files.

解压 rpm 包

RPM 包括是使用 cpio 格式打包的，因此可以先转成 cpio 然后解压，如下所示：

rpm2cpio xxx.rpm | cpio -div

rpm2cpio 命令用于将 rpm 软件包转换为 cpio 格式的文件。

[vagrant@bogon openresty.centos.el7]$ rpm2cpio openresty-pcre-8.42-1.el7.centos.x86_64.rpm | cpio -div
./usr/local/openresty/pcre/lib/libpcre.so

Summary     : OpenResty, scalable web platform by extending NGINX with Lua
Description :
This package contains the core server for OpenResty. Built for production
uses.

OpenResty is a full-fledged web platform by integrating the standard Nginx
core, LuaJIT, many carefully written Lua libraries, lots of high quality
3rd-party Nginx modules, and most of their external dependencies. It is
designed to help developers easily build scalable web applications, web
services, and dynamic web gateways.

By taking advantage of various well-designed Nginx modules (most of which
are developed by the OpenResty team themselves), OpenResty effectively
turns the nginx server into a powerful web app server, in which the web
developers can use the Lua programming language to script various existing
nginx C modules and Lua modules and construct extremely high-performance
web applications that are capable to handle 10K ~ 1000K+ connections in
a single box.

Check RPM dependencies( stackoverflow 商业网/a/19087701)

In fact that's not a one but four different questions:

1、First you can quickly list a downloaded package's dependencies/requirements by using the following commands:

$ rpm -qp mypackage.rpm --provides
$ rpm -qp mypackage.rpm --requires

2、Second, you can use yum utility in order to satisfy these (somewhat cryptic) dependencies automatically (assuming that all your repositories are set up correctly, and all the dependencies are available):

$ sudo yum install mypackage.rpm

3、Third, there are several RPM search resources, some of them already suggested above. I'd like to list another one, just for the reference - pkgs.org.

4、Fourth, there is an additional popular repository for RHEL5 and RHEL6 distros - EPEL. Note that it's not supported by Red Hat.

常用命令

1. Install RPM File : # rpm -ivh awstats.i386.rpm
2. Upgrade RPM File : # rpm -Uvh awstats.i386.rpm
   1, Erase (Delete) RPM File (package): # rpm -ev packagename
3. To find list of all install packages, enter:
   • # rpm -qa
   • # rpm -qa | less
   • # rpm -qa | grep something
