適用場景：
1.大型集羣中的應用服務器只能內網訪問
2.希望保持穩定的本地存儲庫,保證成員服務器統一安裝
3.避免因爲國外yum源或者國內源網絡不佳的情況訪問
服務器配置：
創建應用本地yum源配置文件，確保網絡正常訪問公網源，以CDH爲例
[root@vm03 ~]# cat /etc/yum.repos.d/cdh.repo [cloudera-cdh5] # Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat or CentOS 6 x86_64 name=Cloudera's Distribution for Hadoop, Version 5 baseurl=http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5/ gpgkey = http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/RPM-GPG-KEY-cloudera gpgcheck = 1
2.在RPM服務器上安裝Apache/nginx或者ftp等web文件服務器，能讓其他服務器通過網絡方式訪問源
[root@vm03 ~]# /etc/init.d/httpd start Starting httpd: [ OK ]
3.安裝createrepo，reposync工具
[root@vm03 ~]#yum install yum-utils createrepo -y
4.將源中的rpm同步到本地
[root@vm03 html]# pwd /var/www/html [root@vm03 html~]#reposync -r cloudera-cdh5 #cloudera-cdh5指cdh.repo中的源名稱 [root@vm03 html]# mv cloudera-cdh5 cdh
5.規範目錄及命名方式，/本地目錄/項目名稱/版本號/RPMS/架構平臺
[root@vm03 html]# tree . └── cdh └── 5 └── RPMS ├── noarch │ ├── avro-doc-1.7.6+cdh5.4.8+97-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── avro-libs-1.7.6+cdh5.4.8+97-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── avro-tools-1.7.6+cdh5.4.8+97-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── bigtop-tomcat-0.7.0+cdh5.4.8+0-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── bigtop-utils-0.7.0+cdh5.4.8+0-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── crunch-0.11.0+cdh5.4.8+76-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── crunch-doc-0.11.0+cdh5.4.8+76-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── flume-ng-1.5.0+cdh5.4.8+137-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── flume-ng-agent-1.5.0+cdh5.4.8+137-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── flume-ng-doc-1.5.0+cdh5.4.8+137-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── hbase-solr-1.5+cdh5.4.8+60-1.cdh5.4.8.p0.5.el6.noarch.rpm │ ├── hbase-solr-doc-1.5+cdh5.4.8+60-1.cdh5.4.8.p0.5.el6.noarch.rpm └── x86_64 ├── bigtop-jsvc-0.6.0+cdh5.4.8+684-1.cdh5.4.8.p0.5.el6.x86_64.rpm ├── bigtop-jsvc-debuginfo-0.6.0+cdh5.4.8+684-1.cdh5.4.8.p0.5.el6.x86_64.rpm ├── hadoop-0.20-conf-pseudo-2.6.0+cdh5.4.8+669-1.cdh5.4.8.p0.5.el6.x86_64.rpm ├── hadoop-0.20-mapreduce-2.6.0+cdh5.4.8+669-1.cdh5.4.8.p0.5.el6.x86_64.rpm ├── hadoop-0.20-mapreduce-jobtracker-2.6.0+cdh5.4.8+669-1.cdh5.4.8.p0.5.el6.x86_64.rpm ├── hadoop-0.20-mapreduce-jobtrackerha-2.6.0+cdh5.4.8+669-1.cdh5.4.8.p0.5.el6.x86_64.rpm
6.建立版本倉庫信息
[root@vm03 html]# cd cdh/5/ [root@vm03 5]# createrepo . Spawning worker 0 with 118 pkgs Workers Finished Gathering worker results Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@vm03 5]# ls repodata RPMS
7.客戶端斷網測試
[root@vm02 ~]# cat /etc/yum.repos.d/cdh5.repo [cloudera-cdh5] name=cdh5 baseurl=http://192.168.2.54/cdh/5/ gpgcheck=0 [root@vm02 ~]# yum makecache Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile cloudera-cdh5 | 2.9 kB 00:00 cloudera-cdh5/filelists_db | 390 kB 00:00 cloudera-cdh5/primary_db | 66 kB 00:00 cloudera-cdh5/other_db | 7.7 kB 00:00 Metadata Cache Created
