CentOS7創建本地源過程

1）使用yum安裝http服務（主節點）

yum -y install httpd

2）將httpd服務加入系統自啟動服務並設置開機啟動

systemctl start httpd    #啟動apache服務器
systemctl stop httpd     #關閉apache服務器
systemctl enable httpd 　#設置開機自動啟動
systemctl status httpd.service  #檢查httpd服務狀態 

3）下載CM5.12.1rpm包（注意：此路徑包含的是CentOS7版本的rpm包）

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

將以上7個文件下載/var/www/html/cm5.12.1目錄下

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

4）創建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）訪問http://hadoop101.com/cm5.12.1/確認本地源是否能正常訪問

6）配置cm的本地源，在/etc/yum.repo.d/目錄下增加cm.repo文件，寫入以下配置

[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）驗證CM源是否配置成功

[root@hadoop101 cm5.12.1]# yum repolist
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.nju.edu.cn * extras: mirrors.njupt.edu.cn * updates: mirrors.njupt.edu.cn cmrepo | 2.9 kB 00:00:00 cmrepo/primary_db | 1.1 kB 00:00:00 repo id repo name status base/7/x86_64 CentOS-7 - Base 10,019 cmrepo CM5.12.1 0 extras/7/x86_64 CentOS-7 - Extras 435 updates/7/x86_64 CentOS-7 - Updates 2,500 repolist: 12,954

8）將cm.repo分發到其余各節點

[root@hadoop101 cm5.12.1]# xsync /etc/yum.repos.d/cm.repo 
fname=cm.repo pdir=/etc/yum.repos.d ------------------- hadoop102 -------------- sending incremental file list cm.repo sent 181 bytes received 35 bytes 144.00 bytes/sec total size is 89 speedup is 0.41 ------------------- hadoop103 -------------- sending incremental file list cm.repo sent 181 bytes received 35 bytes 432.00 bytes/sec total size is 89 speedup is 0.41
