5-2 7 yum更换国内源 下载rpm包 源码安装

7.6 yum 更换国内源

备份，清空

[root@axiang-02 ~]# ls /etc/yum.repos.d
CentOS-Base.repo       CentOS-Media.repo    epel.repo
CentOS-CR.repo         CentOS-Sources.repo  epel-testing.repo
CentOS-Debuginfo.repo  CentOS-Vault.repo    percona-release.repo
CentOS-fasttrack.repo  epel-7.repo
[root@axiang-02 ~]# cp /etc/yum.repos.d /etc/yum.repos.d.bak 
[root@axiang-02 ~]# rm -f /etc/yum.repos.d/*

下载阿里源

[root@axiang-02 ~]# cd /etc/yum.repos.d
[root@axiang-02 yum.repos.d]# wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@axiang-02 yum.repos.d]# wget http://mirrors.aliyun.com/repo/epel-7.repo    //添加EPEL源
[root@axiang-02 yum.repos.d]# ls
CentOS-Base.repo  epel-7.repo

清理缓存并生成新的缓存

[root@axiang-02 yum.repos.d]# yum clean all
[root@axiang-02 yum.repos.d]# yum makecache

• http://mirrors.aliyun.com/repo/
• http://mirrors.163.com/.help/centos.html
• curl -O url 也能够下载

7.7 yum下载rpm包

不少东西yum没有，须要安装扩展源epel

[root@axiang-03 ~]# yum install -y epel-release 
yum list |grep epel  //查看 有不少

[root@axiang-03 ~]# yum install -y zmap --downloadonly
[root@axiang-03 ~]# find / -type f -name zmap-2.1.1-1.el7.x86_64.rpm
/var/cache/yum/x86_64/7/epel/packages/zmap-2.1.1-1.el7.x86_64.rpm    //默认下载到这里

将安装过的rpm包下载到指定位置

[root@axiang-03 ~]# yum reinstall -y epel-release --downloadonly --downloaddir=/root/

7.8 - 7.9 源码包安装

[root@axiang-03 ~]# cd /usr/local/src
[root@axiang-03 src]# wget https://mirrors.cnnic.cn/apache/httpd/httpd-2.4.27.tar.bz2

[root@axiang-03 src]# tar jxvf httpd-2.4.27.tar.bz2 //注意解压会直接覆盖同名目录
[root@axiang-03 src]# cd httpd-2.4.27/  
[root@axiang-03 httpd-2.4.27]# ./configure --prefix=/usr/local/apache2.4  //安装初始化，指定位置等信息
[root@axiang-03 httpd-2.4.27]# echo $?  //检查
0
[root@axiang-03 httpd-2.4.27]# make && make install  //源码封装，安装

• 卸载就是中止进程后删除安装的文件目录

扩展

1. 配置yum源优先级 http://ask.apelearn.com/question/7168
2. 把源码包打包成rpm包 http://www.linuxidc.com/Linux/2012-09/70096.htm
