In this tutorial, we will show you how to Install Oracle Database 12c On CentOS 7
OS information:
[root@ora-c7 ~]# cat /etc/centos-release CentOS Linux release 7.0.1406 (Core)
Network:
[root@ora-c7 ~]# ip a | grep inet inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host inet 192.168.119.139/24 brd 192.168.119.255 scope global dynamic eno16777736 inet6 fe80::20c:29ff:fe41:1494/64 scope link
Login as root and add required groups:
/usr/sbin/groupadd -g 501 oinstall /usr/sbin/groupadd -g 502 dba /usr/sbin/groupadd -g 503 oper
Add user Oracle:
/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle
Change password for user:
passwd oracle
Add kernel parameters to /etc/sysctl.conf.
kernel.shmmni = 4096 kernel.shmmax = 4398046511104 kernel.shmall = 1073741824 kernel.sem = 250 32000 100 128 fs.aio-max-nr = 1048576 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586
Apply kernel parameters:
/sbin/sysctl -p
Add following lines to set shell limits for user oracle in file /etc/security/limits.conf
oracle soft nproc 131072 oracle hard nproc 131072 oracle soft nofile 131072 oracle hard nofile 131072 oracle soft core unlimited oracle hard core unlimited oracle soft memlock 50000000 oracle hard memlock 50000000
Edit /etc/hosts file:
[root@ora-c7 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.119.139 ora-c7.unixmen.local
Verify your network settings:
[root@ora-c7 ~]# ping -c 1 O7-unixmen PING ora-c7.unixmen.local (192.168.119.139) 56(84) bytes of data. 64 bytes from ora-c7.unixmen.local (192.168.119.139): icmp_seq=1 ttl=64 time=0.017 ms

Modify .bash_profile for user oracle in his home directory add at the end file /home/oralce/.bash_profile.

Check which packages are installed and which are missing.
as root copy this and execute this:
yum groupinstall "GNOME Desktop" -y yum groupinstall "Development Tools" -y
yum install binutils -y yum install compat-libstdc++-33 -y yum install compat-libstdc++-33.i686 -y yum install gcc -y yum install gcc-c++ -y yum install glibc -y yum install glibc.i686 -y yum install glibc-devel -y yum install glibc-devel.i686 -y yum install ksh -y yum install libgcc -y yum install libgcc.i686 -y yum install libstdc++ -y yum install libstdc++.i686 -y yum install libstdc++-devel -y yum install libstdc++-devel.i686 -y yum install libaio -y yum install libaio.i686 -y yum install libaio-devel -y yum install libaio-devel.i686 -y yum install libXext -y yum install libXext.i686 -y yum install libXtst -y yum install libXtst.i686 -y yum install libX11 -y yum install libX11.i686 -y yum install libXau -y yum install libXau.i686 -y yum install libxcb -y yum install libxcb.i686 -y yum install libXi -y yum install libXi.i686 -y yum install make -y yum install sysstat -y yum install unixODBC -y yum install unixODBC-devel -y yum install zlib-devel -y
Create directory structure:
mkdir -p /u01/app/oracle/product/12.1.0 chown -R oracle:oinstall /u01/ chmod 775 /u01/app
Disable selinux by editing the “/etc/selinux/config” file,
SELINUX=permissive
Install database software
Let’s start with database software installation as oracle user.
su - oracle
Unzip the database install files:
unzip linuxamd64_12c_database_1of2.zip unzip linuxamd64_12c_database_2of2.zip [oracle@ora-c7 ~]$ cd database/
[oracle@ora-c7 database]$ ./runInstaller Starting Oracle Universal Installer... Checking Temp space: must be greater than 500 MB. Actual 21246 MB Passed Checking swap space: must be greater than 150 MB. Actual 2447 MB Passed Checking monitor: must be configured to display at least 256 colors. Actual 16777216 Passed Preparing to launch Oracle Universal Installer from /tmp/OraInstall2014-10-29_05-53-46AM. Please wait ..
During the linking phase, you will see the following error.
Error in invoking target 'links proc gen_pcscfg procob' of makefile '/u01/app/oracle/product/12.1.0.2/db_1/precomp/lib/ins_precomp.mk'. See '/u01/app/oraInventory/logs/installActions2014-10-29_09-07-03PM.log' for details.
To fix it, do the following:
rm -rf $ORACLE_HOME/lib/stubs/* cp $ORACLE_HOME/rdbms/lib/env_rdbms.mk $ORACLE_HOME/rdbms/lib/env_rdbms.mk.orig
Perform the following modifications:
vi $ORACLE_HOME/rdbms/lib/env_rdbms.mk
# Line 176 # FROM: LINKTTLIBS=$(LLIBCLNTSH) $(ORACLETTLIBS) $(LINKLDLIBS) # TO : LINKTTLIBS=$(LLIBCLNTSH) $(ORACLETTLIBS) $(LINKLDLIBS) -lons # Line 279-280 # FROM: LINK=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS) $(COMPSOBJS) LINK32=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS32) $(COMPSOBJS) # TO : LINK=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS) $(COMPSOBJS) -Wl,--no-as-needed LINK32=$(FORT_CMD) $(PURECMDS) $(ORALD) $(LDFLAGS32) $(COMPSOBJS) -Wl,--no-as-needed # Line 3041-3042 # FROM: TG4PWD_LINKLINE= $(LINK) $(OPT) $(TG4PWDMAI) \ $(LLIBTHREAD) $(LLIBCLNTSH) $(LINKLDLIBS) # TO : TG4PWD_LINKLINE= $(LINK) $(OPT) $(TG4PWDMAI) \ $(LLIBTHREAD) $(LLIBCLNTSH) $(LINKLDLIBS) -lnnz12
Click the “Retry” button.
Now, the installation should continue.
