CentOS7创建本地源过程

1）使用yum安装http服务（主节点）

yum -y install httpd

2）将httpd服务加入系统自启动服务并设置开机启动

systemctl start httpd    #启动apache服务器
systemctl stop httpd     #关闭apache服务器
systemctl enable httpd 　#设置开机自动启动
systemctl status httpd.service  #检查httpd服务状态 

3）下载CM5.12.1rpm包（注意：此路径包含的是CentOS7版本的rpm包）

（https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.12.1/RPMS/x86_64/）

将以上7个文件下载/var/www/html/cm5.12.1目录下

mkdir -p /var/www/html/cm5.12.1
cd /var/www/html/cm5.12.1/

4）创建cm本地源

[root@hadoop101 cm5.12.1]# cd /var/www/html/cm5.12.1/
[root@hadoop101 cm5.12.1]# createrepo .
Spawning worker 0 with 7 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete

5）访问http://hadoop101.com/cm5.12.1/确认本地源是否能正常访问

6）配置cm的本地源，在/etc/yum.repo.d/目录下增加cm.repo文件，写入以下配置

[root@hadoop101 cm5.12.1]#  vim /etc/yum.repos.d/cm.repo
[cmrepo]
name=CM5.12.1
baseurl=http://hadoop101.com/cm5.12.1
gpgcheck=false
enabled=true

7）验证CM源是否配置成功

[root@hadoop101 cm5.12.1]# yum repolist

8）将cm.repo分发到其余各节点

[root@hadoop101 cm5.12.1]# xsync /etc/yum.repos.d/cm.repo 
fname=cm.repo
pdir=/etc/yum.repos.d
------------------- hadoop102 --------------
