制作rpm包，可以免除多次编译安装

步骤一：安装rpm-build软件

1）安装rpm-build软件包

[root@root ~]# yum -y install rpm-build

2）生成rpmbuild目录结构

[root@root ~]# rpmbuild -ba nginx.spec                //会报错，没有文件或目录

[root@root ~]# ls /root/rpmbuild                    //自动生成的目录结构

BUILD BUILDROOT RPMS SOURCES SPECS SRPMS

3）准备工作，将源码软件复制到SOURCES目录

[root@root ~]# cp nginx-1.12.2.tar.gz /root/rpmbuild/SOURCES/

4）创建并修改SPEC配置文件

[root@root ~]# vim /root/rpmbuild/SPECS/nginx.spec

Name:nginx                                        #源码包软件名称

Version:1.12.2                                    #源码包软件的版本号

Release:    10                                        #制作的RPM包版本号

%install

make install DESTDIR=%{buildroot}

步骤二：使用配置文件创建RPM包

1）安装依赖软件包

[root@root ~]# yum -y install gcc pcre-devel openssl-devel

2）rpmbuild创建RPM软件包

[root@root ~]# rpmbuild -ba /root/rpmbuild/SPECS/nginx.spec

[root@root ~]# ls /root/rpmbuild/RPMS/x86_64/nginx-1.12.2-10.x86_64.rpm

步骤三：安装、卸载软件

[root@root ~]# rpm -ivh /root/rpmbuild/RPMS/x86_64/nginx-1.12.2-10.x86_64.rpm

[root@root ~]# rpm -qa |grep nginx

[root@root ~]# /usr/local/nginx/sbin/nginx

[root@root ~]# curl http://127.0.0.1/
