Ready to work
The main function of yum (Yellow dog Updater, Modified) is to facilitate adding, deleting and updating rpm packages. It can solve the problem of package dependencies and make it easier to manage a large number of system update problems. It can configure multiple repositories or repositories at the same time, which is where updated and dependent packages are stored.
Experimental environment:
[root@cache ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)
host: cache ip address: 192.168.4.2
host: db1 ip address: 192.168.4.3
Note: two hosts Both yum sources can handle other dependencies.
The following link is the prepared source package and the prepared rpm package, which can be downloaded and used directly if necessary.

First, the source code is made into an RPM package
Make the source code into an RMP package on the host cache
[root@cache ~]# yum -y install rpm-build //用于做rpm包的工具
[root@cache ~]# rpmbuild -ba nginx-1.8.0.tar.gz //故意让这个命令报错，用于生成6个文件
[root@cache ~]# ls //查看/root下会生成rpmbuild目录
anaconda-ks.cfg Downloads nginx-1.8.0.tar.gz rpmbuild
[root@cache ~]# ls /root/rpmbuild/ //查看6个自动生成的目录
BUILD BUILDROOT RPMS SOURCES SPECS SRPMS
[root@cache ~]# cp /root/nginx-1.8.0.tar.gz /root/rpmbuild/SOURCES/ //将下载好的源码包拷贝到SOURCES目录下
[root@cache ~]# ls /root/rpmbuild/SOURCES/
nginx-1.8.0.tar.gz
[root@cache ~]# cd /root/rpmbuild/SPECS/ //存放spec文件的目录
[root@cache SPECS]# vim nginx.spec //创建nginx.spec文件，文件内会自动在文件生成一些内容，以下是删除一部分的内容
Name:nginx //不能任意，为软件名
Version:1.8.0 //不能任意，为软件版本号
Release:1 //第几次打rpm包

Add the prepared rpm package to the local yum source on the host db1, and install it for testing
[root@db1 ~]# mkdir /nginx //创建nginx目录，用于做本地的yum源，目录名字任意
[root@db1 ~]# cp nginx-1.8.0-1.x86_64.rpm /nginx/ 将做好的rmp包拷贝到yum源目录
[root@db1 ~]# createrepo /nginx/ //创建yum仓库的，createrepo 目录
[root@db1 ~]# ls /nginx/ //查看，会多个自动生成的repodata目录
nginx-1.8.0-1.x86_64.rpm repodata
[root@db1 ~]# yum-config-manager --add file:///nginx //添加本地yum仓库
[root@db1 ~]# yum clean all //清除

[root@db1 ~]# yum -y install nginx //用yum安装nginx
