Configure yum  server on Linux for Package 

installation.


Step 1:-

[root@oem pub]#

[root@oem ~]# cd /media

[root@oem media]# ls

OL6.8 x86_64 Disc 1 20160518

[root@oem media]# cd OL*

[root@oem OL6.8 x86_64 Disc 1 20160518]# pwd

/media/OL6.8 x86_64 Disc 1 20160518

[root@oem OL6.8 x86_64 Disc 1 20160518]# ls

[root@oem OL6.8 x86_64 Disc 1 20160518]# cd Server/

[root@oem Server]# pwd

[root@oem Server]# ls

listing  oracle_updated  Packages  repodata  TRANS.TBL

[root@oem Server]# cd Packages/

[root@oem Packages]# pwd

/media/OL6.8 x86_64 Disc 1 20160518/Server/Packages

[root@oem Packages]#

here we have all necessary packages available which is required to install on the Linux server.

Step 2:

create or user  /var/ftp/pub directory 

[root@oem Packages]# ls -ld /var/ftp/pub

drwxr-xr-x. 2 root root 4096 May 11  2016 /var/ftp/pub

[root@oem Packages]#

copy the all packages  to  /var/ftp/pub location using cp command.

[root@oem Packages]# ls -ld /var/ftp/pub

drwxr-xr-x. 2 root root 4096 May 11  2016 /var/ftp/pub

[root@oem Packages]# cp * /var/ftp/pub

[root@oem Packages]# cd /var/ftp/pub

[root@oem ftp]# du -sh pub

3.5G    pub

createrepo -v /var/ftp/pub

Step 3.

[root@oem ftp]# yum clean all

Loaded plugins: refresh-packagekit, security, ulninfo

Cleaning repos: InstallMedia public_ol6_UEKR4 public_ol6_latest

Cleaning up Everything

Go to create client file configuration 

[root@oem ftp]# cd /etc/yum.repos.d/

[root@oem yum.repos.d]# ls

packagekit-media.repo  public-yum-ol6.repo

Create your custom repo.

[root@oem yum.repos.d]# vi localserver.repo

[root@oem yum.repos.d]# cat localserver.repo

[rhel]

name=station

baseurl=file:///var/ftp/pub

gpgcheck=0

enabled=1

Step 4:

Now your ready  to check yum list all

[root@oem yum.repos.d]# yum list all

Loaded plugins: refresh-packagekit, security, ulninfo

http://yum.oracle.com/repo/OracleLinux/OL6/UEKR4/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'yum.oracle.com'"

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: public_ol6_UEKR4. Please verify its path and try again

[root@oem yum.repos.d]#

I got this error lest check what i did wrong?

[root@oem yum.repos.d]# mv packagekit-media.repo packagekit-media-bkp

[root@oem yum.repos.d]# mv public-yum-ol6.repo public-yum-ol6-bkp

[root@oem yum.repos.d]#

[root@oem yum.repos.d]# yum list all

still same error now i got  it now ,what i forgot

createrepo -v /var/ftp/pub

[root@oem yum.repos.d]# createrepo -v /var/ftp/pub

lets verify check rpm available from  yum repository 

[root@oem ~]# yum list | grep oracle*

lets install one package which is required For oracle 12c Database installtion.

[root@oem yum.repos.d]# rpm -qa | grep oracle-rdbms-server-12cR1-preinstall

oracle-rdbms-server-12cR1-preinstall-1.0-14.el6.x86_64

[root@oem yum.repos.d]#

STEP 5:- Install the  packages with below command.

[root@oem yum.repos.d]#   yum install oracle-rdbms-server-12cR1-preinstall

Loaded plugins: refresh-packagekit, security, ulninfo

Setting up Install Process

Package oracle-rdbms-server-12cR1-preinstall-1.0-14.el6.x86_64 already installed and latest version

Nothing to do

[root@oem yum.repos.d]#

[root@oem ~]# cat /etc/sysctl.conf

some snippets from this files .

net.core.rmem_max = 4194304

# oracle-rdbms-server-11gR2-preinstall setting for net.core.wmem_default is 262144
net.core.wmem_default = 262144

# oracle-rdbms-server-11gR2-preinstall setting for net.core.wmem_max is 1048576
net.core.wmem_max = 1048576

# oracle-rdbms-server-11gR2-preinstall setting for fs.aio-max-nr is 1048576
fs.aio-max-nr = 1048576

# oracle-rdbms-server-11gR2-preinstall setting for net.ipv4.ip_local_port_range is 9000 65500
net.ipv4.ip_local_port_range = 9000 65500

Another configuration file.

oracle   hard   nproc    16384

# oracle-rdbms-server-11gR2-preinstall setting for stack soft limit is 10240KB

oracle   soft   stack    10240

# oracle-rdbms-server-11gR2-preinstall setting for stack hard limit is 32768KB

oracle   hard   stack    32768

# oracle-rdbms-server-11gR2-preinstall setting for memlock hard limit is maximum of {128GB (x86_64) / 3GB (x86) or 90 % of RAM}

oracle   hard   memlock    134217728

# oracle-rdbms-server-11gR2-preinstall setting for memlock soft limit is maximum of {128GB (x86_64) / 3GB (x86) or 90% of RAM}

oracle   soft   memlock    134217728

This is the advantage of this oracle-rdbms-server-12cR1-preinstall packages.No manul way like we did in earliear version 9i,10G 

I am lucky here i already installed the packages.Due this packages the basic kernel parameter  which are required for Oracle Database software installation are already set automatically.
