How To Create Local YUM Repository On RHEL 6

In this post, I will by showing how to create a yum local repository on RHEL 6


1) You must be having a RHEL cd with you for creating the YUM repository
-- Load the physical CD to your CD ROM, In case its a physical server, Mount the CD into a mount point (/mnt/cdrom)
-- In my case it is a VM so I have an ISO image (Virtual CD), which is loaded and mounted into a mount point (/mnt/cdrom)

[root@ajithpathiyil_MT1 rhel64]# cd /mnt/cdrom
[root@ajithpathiyil_MT1 cdrom]# ls -ltr

2) Make a local directory and copy the contents of (/mnt/cdrom/Server) to this newly created local directory

[root@ajithpathiyil_MT1 cdrom]# mkdir -p /opt/yum/rhel64
[root@ajithpathiyil_MT1 cdrom]# cd /opt/yum/rhel64


[root@ajithpathiyil_MT1 Server]# cp -a *.rpm /opt/yum/rhel64/
[root@ajithpathiyil_MT1 Server]# uname -a

3) Copy the comps-rhel5-server-core.xml file to your local directory as (/opt/yum/rhel64/repodata/comps.xml)

[root@ajithpathiyil_MT1 Server]# cd ..
[root@ajithpathiyil_MT1 Server]# cd repodata
[root@ajithpathiyil_MT1 repodata]# mkdir -p /opt/yum/rhel64/repodata
[root@ajithpathiyil_MT1 repodata]# ls -ltr *comps*xml

[root@ajithpathiyil_MT1 repodata]# cp *comps*xml /opt/yum/rhel64/repodata/comps.xml

4) Install the createrepo-0.4.11-3.el5.noarch rpm if not installed already.

[root@ajithpathiyil_MT1 repodata]# cd /opt/yum/rhel64/

How To Cleanup Grid Infrastructure After Installtion Failure

This blogpost is about how to clean up the failed Grid Infrastructure installation,When Grid Infrastructure installation fails, especially while running the root.sh script, Failure maybe due to various reasons. My failure reason was that, I was installing GI and in my VM I had allocated very little memory, due to which the root.sh script hanged, patiently waited for 3 hours, nothing moved, had to abruptly shutdown the VM and go home.

C:\>"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list hdds

1)      When checked, it was a half baked situation, In node “ajithn1” ASM instance was up and running and all crs services were up

Using username "oracle".

[root@ajithn1 ~]#

2)      In node “ajithn2”, again ASM instance was up but cluster services were not.
Using username "oracle".
Last login: Sun Apr 10 16:58:58 2016
[oracle@ajithn2 ~]$ ps -ef|grep pmon

3)      Now, how to cleanup your GI installation? To do a cleanup execute the below perl command on all the nodes but not the last node (I have only 2 nodes, so second node will have a slightly different command)

[oracle@ajithn1 ~]$ perl /u01/grid/oracle/product/11.2.0/grid_1/crs/install/rootcrs.pl -verbose -deconfig -force

5)      My ASM instance was also up, But when I try to reinstall the GI, I will not be able to use the already used ASM devices (sdb1, sdc1), So, let’s scribble something on the headers of the devices to erase the details of ASM DG and make it reusable. (Using dd command to erase the ASM diskgroup details from device headers)

[root@ajithn1 ~]# /etc/init.d/oracleasm listdisks
BACKUP
DATA
[root@ajithn1 ~]# dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100
100+0 records in
100+0 records out
102400 bytes (102 kB) copied, 0.267837 seconds, 382 kB/s
[root@ajithn1 ~]# dd if=/dev/zero of=/dev/sdc1 bs=1024 count=100

6)      Removing the ASM Diskgroups

[root@ajithn1 ~]# /etc/init.d/oracleasm deletedisk DATA /dev/sdb1
Removing ASM disk "DATA":                                  [  OK  ]
[root@ajithn1 ~]# /etc/init.d/oracleasm deletedisk BACKUP /dev/sdc1
Removing ASM disk "BACKUP":                                [  OK  ]
[root@ajithn1 ~]# /etc/init.d/oracleasm listdisks
[root@ajithn1 ~]#

7)      Recreating the ASM diskgroups.

[root@ajithn1 ~]# /etc/init.d/oracleasm createdisk data /dev/sdb1
Marking disk "data" as an ASM disk:                        [  OK  ]
[root@ajithn1 ~]# /etc/init.d/oracleasm createdisk backup /dev/sdc1
Marking disk "backup" as an ASM disk:                      [  OK  ]
[root@ajithn1 ~]# /etc/init.d/oracleasm listdisks
BACKUP
DATA
[root@ajithn1 ~]#


Once the ASM Diskgroups are recreated, we can restart the GI installation and it should be successful, and I had a successful installation after I increased my VM memory.



HAPPY LEARNING!
