一、前言
最近正在学习redis，但是在安装redis的时候遇到很多坎，在此记录一下。
硬件环境：我用 VMware Workstation Pro 12 安装 Red Hat Enterprise Linux 7
终端工具：SecureCRT 5
软件版本：redis-3.0.0.tar.gz
二、遇到的问题及解决
当进入解压（tar -zxvf *）后的 redis-3.0.0，执行 make 编译命令时，提示 gcc 未安装。所以开始着手安装 gcc ，通过搜索网上相关资料，
尝试用 yum install gcc 进行安装，但提示我未找到相关的源。后来通过 http://blog.chinaunix.net/uid-20729583-id-2972852.html，
该博文进行设置，如下：
检查yum是否安装，默认情况下都是安装好的
[root@linux-a ~]# rpm -qa |grep yum
配置yum更新源
创建/etc/yum.repos.d/CentOS-Base.repo文件，定义yum更新源，这里使用的是上海交大的CentOS更新源 [root@linux-a ~]# vi /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS-5-Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/ gpgcheck=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #released updates [update] name=CentOS-5-Updates #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/ gpgcheck=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #packages used/produced in the build but not released [addons] name=CentOS-5-Addons #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/ gpgcheck=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that may be useful [extras] name=CentOS-5-Extras #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/ gpgcheck=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-5-Plus #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/ gpgcheck=0 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #contrib - packages by Centos Users [contrib] name=CentOS-5-Contrib #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/ gpgcheck=0 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 # vi dag.repo [dag] name=Dag RPM Repository for RHEL5 baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/ enabled=1 gpgcheck=0 gpgkey=http://ftp.riken.jp/Linux/dag/packages/RPM-GPG-KEY.dag.txt
导入key配置yum
[root@linux-a ~]# rpm --import http://ftp.sjtu.edu.cn/centos/5/os/i386/RPM-GPG-KEY-CentOS-5
以上配置好yum，然后通过yum进行安装。
