Installing Oracle 12c R1 Grid Infrastructure on Linux 7

You might be interested in installing 12cR1 Grid Infrastructure (for a standalone server) software in order to use ASM and/or Oracle Restart feature of GI. In the following I will explain how to install GI for a standalone server on Linux 7. For this installation, I am using Oracle Linux 7. You might also want to check how to install Oracle 12cR1 GI on Linux 6

1)
Make sure you have entries in the /etc/host file for the name resolution.

127.0.0.1   localhost localhost.localdomain localhost 192.231.231.40 salman1.salman.com salman1

Download and unzip the software 
Download 12c Grid Infrastructure and RDBMS softwares.
First release (12.1.0.1) can be downloaded from www.oracle.com, but since we are installing 12.1.0.2 here, we would need to download patch set 1769377. First 2 zip files are for database and last 2 are for Grid Infrastructure binaries.

2)
Edit /etc/selinux/config and set value for SELINUX to either “permissive” or “disabled”

SELINUX=permissive

3)
As root user, configure Shared Memory File System. Add following line in /etc/fstab file for shared memory file system. Modify the value of “size” based on the amount of memory you will be using for your SGA

tmpfs                                   /dev/shm                tmpfs   rw,exec,size=8g        0 0

4)
Disable the firewall

[root@salman1 ~]# systemctl start firewalld.service [root@salman1 ~]# systemctl stop firewalld.service [root@salman1 ~]# systemctl disable firewalld.service rm '/etc/systemd/system/basic.target.wants/firewalld.service' rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'

5)
Reboot the host

6) 
We can perform automatic configuration of the node using “yum” command. If you want to do manual configuration, skip this step and go to next step (step 7).
Automatic configuration would perform following tasks
- Installation of required RPM packages
- Setup kernel parameters in /etc/sysctl.conf file
- Creation of OS groups (oinstall, dba) and OS user (oracle)
- Setting limits for installation user “oracle” 

For Oracle Linux, follow the steps mentioned in the following documents to access the online yum repository.
http://public-yum.oracle.com/

[root@salman1 ~]# yum install oracle-rdbms-server-12cR1-preinstall –y

As already mentioned, above command will install all required packages which are needed for grid infrastructure and/or RDBMS software installation. If you also plan to install a 32-bit client on this x86_64 server, you would also need to install 32-bit version of these RPM packages manually.

[root@salman1 ~]# yum install glibc-2.17-36.el7.i686 [root@salman1 ~]# yum install glibc-devel-2.17-36.el7.i686 [root@salman1 ~]# yum install libaio-0.3.109-9.el7.i686 [root@salman1 ~]# yum install libaio-devel-0.3.109-9.el7.i686 [root@salman1 ~]# yum install libXi-1.7.2-1.el7.i686 [root@salman1 ~]# yum install libXtst-1.2.2-1.el7.i686 [root@salman1 ~]# yum install libgcc-4.8.2-3.el7.i686 [root@salman1 ~]# yum install libstdc++-4.8.2-3.el7.i686 [root@salman1 ~]# yum install libstdc++-devel-4.8.2-3.el7.i686

If you want to install form Oracle Linux installation media, use “rpm -i” command to install the packages.
If you have performed this step; skip next step and go to step 8

7)
Install following RPM packages (or latest version) from either yum repository or from Linux 7 media

binutils-2.23.52.0.1-12.el7.x86_64 compat-libcap1-1.10-3.el7.x86_64 gcc-4.8.2-3.el7.x86_64 gcc-c++-4.8.2-3.el7.x86_64 glibc-2.17-36.el7.i686 glibc-2.17-36.el7.x86_64 glibc-devel-2.17-36.el7.i686 glibc-devel-2.17-36.el7.x86_64 libaio-0.3.109-9.el7.i686 libaio-0.3.109-9.el7.x86_64 libaio-devel-0.3.109-9.el7.i686 libaio-devel-0.3.109-9.el7.x86_64 ksh make-3.82-19.el7.x86_64 libXi-1.7.2-1.el7.i686 libXi-1.7.2-1.el7.x86_64 libXtst-1.2.2-1.el7.i686 libXtst-1.2.2-1.el7.x86_64 libgcc-4.8.2-3.el7.i686 libgcc-4.8.2-3.el7.x86_64 libstdc++-4.8.2-3.el7.i686 libstdc++-4.8.2-3.el7.x86_64 libstdc++-devel-4.8.2-3.el7.i686 libstdc++-devel-4.8.2-3.el7.x86_64 sysstat-10.1.5-1.el7.x86_64 unixODBC-2.3.1 Example (yum) [root@salman1 ~]# yum install glibc Example (Linux Media) [root@salman1 ~]# rpm -i glibc Example (Check after install) [root@salman1 ~]# rpm -q glibc glibc-2.17-55.el7.x86_64

Edit /etc/sysctl.conf add following entries to set kernel parameters

fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.panic_on_oops = 1 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500

Execute following command after adding above lines

/sbin/sysctl -p

8)
Add OS groups and “grid” user

Add groups [root@salman1 ~]#  groupadd -g 54325 asmdba [root@salman1 ~]#  groupadd -g 54328 asmadmin [root@salman1 ~]#  groupadd -g 54329 asmoper Add user [root@salman1 ~]# useradd -u 54322 -g oinstall -G dba,asmdba,asmadmin,asmoper grid Set passwords for the grid user [root@salman1 ~]# passwd grid

9)
As root, create a file under /etc/security/limits.d directory and  set limits for user grid. File name could be any, for example grid_user.conf. Add following lines in this file

grid soft nofile 1024 grid hard nofile 65536 grid soft nproc 16384 grid hard nproc 16384 grid soft stack 10240 grid hard stack 32768 grid hard memlock 134217728 grid soft memlock 134217728

10) 

Install oracleasm-support and oracleasmlib, and then configure oracleasm.
oracleasm kernel driver is built in Oracle Linux and does not need to be installed. After installing oracleasm-support and oracleasmlib packages, oracleasm driver starts working.

If you are using some other flavour of Linux, for example RedHat Linux, then you would need to install all 3 packages (oracleasm driver, oracleasm-support and oracleasmlib).

As root, install oracleasm-support from yum repository or from Linux media, then download oracleasmlib package form the following URL, and install.
http://www.oracle.com/technetwork/server-storage/linux/asmlib/ol7-2352094.html

Install oracleasmlib and oracleasm-support [root@salman1 ~]#  yum install oracleasm-support [root@salman1 ~]#  rpm -i oracleasm-lib* Configure oracleasm (highlighted in red are the inputs during configuration) [root@salman1 ~]# /etc/init.d/oracleasm configure Configuring the Oracle ASM library driver. This will configure the on-boot properties of the Oracle ASM library driver.  The following questions will determine whether the driver is loaded on boot and what permissions it will have.  The current values will be shown in brackets ('[]').  Hitting <ENTER> without typing an answer will keep that current value.  Ctrl-C will abort. Default user to own the driver interface []: grid Default group to own the driver interface []: asmadmin Scan for Oracle ASM disks on boot (y/n) [y]:y Writing Oracle ASM library driver configuration: done Initializing the Oracle ASMLib driver:                     [  OK  ] Scanning the system for Oracle ASMLib disks:               [  OK  ] Check Configuration [root@salman1 ~]# /usr/sbin/oracleasm configure ORACLEASM_UID=grid ORACLEASM_GID=asmadmin ORACLEASM_SCANBOOT=true ORACLEASM_SCANORDER="" ORACLEASM_SCANEXCLUDE="" ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"

11)
As root user, add following lines in /etc/pam.d/login file if not present already

session required /lib64/security/pam_limits.so session required pam_limits.so

12)
As root, partition your disks that you will be using for CRS and other file diskgroups (to be used later for database) and create ASM disks using oracleASMLib. Following document explains how to do this.
Creating ASM disks using ASMLib
For this installation, I have created 3 ASM disks, CRS1, CRS2 and CRS3 which I will use for CRS diskgroup to store OCR.

13)
As root, create directories and change ownership to grid user. 

[root@salman1 ~]# mkdir -p /u01/app/12.1.0/grid [root@salman1 ~]# mkdir -p /u01/app/grid [root@salman1 ~]# chown -R grid:oinstall /u01

14)

Add IO scheduler for ASM disks. Modify highlighted disks names to match your environment as you may have different disks/paths.

[root@salman1 ~]# echo deadline > /sys/block/sdb/queue/scheduler [root@salman1 ~]# echo deadline > /sys/block/sdc/queue/scheduler [root@salman1 ~]# echo deadline > /sys/block/sdd/queue/scheduler

15)
Add following in /home/<username>/.bash_profile file of grid user. At this point, we do no need to set other environment variables i.e. ORACLE_BASE or ORACLE_HOME.

umask 022

16)
As grid user, extrac the binaries downloaded for GI. For this installation, I extracted the binaries under /u02 directory.
Log in as grid user using Linux desktop, or you may also use any X server software. Start installation
$ cd /u02/grid
$ ./runInstaller

17)
Select second option for installing GI for standalone server.

18)
Click Next

19)
Select disks and provide name for ASM diskgroup to store OCR. I have selected 3 ASM disks which are mentioned in step 12 above.

20)
Enter passwords for SYS password.

21)
Click Next

22)
OS groups are already selected on this screen.

23)
Provide oracle base and oracle home directories locations.

24)
Click Next

25)
Click Next. After this screen Prerequisite Check screen will come and will automatically move to next screen if no problems found. If Prerequisites Check screen stops and displays some issue, resolve that before moving forward.

26)
Click Next

27)
Monitor the progress

28)
Log in as root from a terminal windows and execute the scripts one my one as mentioned in the following screen. Click OK after executing both scripts.

After running above script, output should be as follows (copied from command prompt)

[root@salman1 u01]# /u01/app/oraInventory/orainstRoot.sh Changing permissions of /u01/app/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world.
