In today’s article, I will explain how to install Oracle 12c Client on Centos 7.<\/p>\n

We do the following package installations.<\/p>\n

sudo yum install wget -y\r\nwget http:\/\/mirror.centos.org\/centos\/7\/os\/x86_64\/Packages\/libaio-devel-0.3.109-13.el7.x86_64.rpm\r\nyum install libaio-devel-0.3.109\u201313.el7.x86_64.rpm -y<\/pre>\n
We create the Oracle user.<\/p>\n
passwd oracle<\/pre>\n
We check the “\/etc\/selinux\/config” file and check if SELINUX is as follows.<\/p>\n
SELINUX=permissive<\/pre>\n
After completing the above process, we reboot the machine and run the following command.<\/p>\n
setenforce Permissive<\/pre>\n
We disable the firewall.<\/p>\n
systemctl stop firewalld\r\nsystemctl disable firewalld<\/pre>\n
We create the directories where the oracle client will be installed and grant the oracle user the necessary privileges.<\/p>\n
mkdir -p \/u01\/app\/oracle\/product\/12.1.0\/client_1\r\nchown -R oracle:oinstall \/u01\r\nchmod -R 775 \/u01<\/pre>\n
We log in as root and enter the following command.<\/p>\n
xhost +<machine-name><\/pre>\n
We set the following information into the .bash_profile.<\/p>\n
# Oracle Settings\r\nexport ORACLE_BASE=\/u01\/app\/oracle\r\nexport ORACLE_HOME=$ORACLE_BASE\/product\/client\/11.2.0\/client_1\r\nexport PATH=\/usr\/sbin:\/usr\/local\/bin:$PATH\r\nexport PATH=$ORACLE_HOME\/bin:$PATH\r\nexport LD_LIBRARY_PATH=$ORACLE_HOME\/lib:\/lib:\/usr\/lib<\/pre>\n
After changing the content of the .bash_profile, we run the following command.<\/p>\n
. .bash_profile<\/pre>\n
We login to the Oracle user and set the DISPLAY variable.<\/p>\n
DISPLAY=<machine-name>:0.0; export DISPLAY<\/pre>\n
We go to the $ORACLE_HOME directory and unzip the downloaded Oracle client software. After the unzip process is finished, we run the .\/runInstaller command and start the software.<\/p>\n
cd $ORACLE_HOME\r\nunzip -oq \/path\/to\/software\/V46097\u201301.zip\r\n.\/runInstaller<\/pre>\n
After the installation starts, we will see the following screen. We select the Administrator option and continue.<\/p>\n
<\/p>\n
We choose the language and continue.<\/p>\n
<\/p>\n
Since we defined .bash_profile directories before, directories come by default. We continue unaltered.<\/p>\n
<\/p>\n
The directory will come by default. We continue unaltered.<\/p>\n
<\/p>\n
The summary section contains information about the client. We start the installation by clicking Install.<\/p>\n
<\/p>\n
While the installation is in progress, when the following screen comes up, we copy the command and run it in the root user.<\/p>\n
\/u01\/app\/oraInventory\/orainstRoot.sh<\/pre>\n
<\/p>\n
After successfully completing the Oracle Client installation, we click the Close button and close it.<\/span><\/p>\n
<\/p>\n
After the installation is finished, we create the tnsnames.ora file. Its content should be as follows.<\/p>\n
$ORACLE_HOME\/network\/admin\/tnsnames.ora<\/pre>\n
orcl =\r\n(DESCRIPTION =\r\n(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.2)(PORT = 1521))\r\n(CONNECT_DATA =\r\n(SERVER = DEDICATED)\r\n(SERVICE_NAME = orcl)\r\n) )<\/pre>\n
After completing all the operations, we connect to the database with the following sqlplus command.<\/p>\n
sqlplus <user>\/<password>@<SID><\/pre>\n
