With the advent of the era of cloud computing and big data, Oracle database plays an increasingly important role in enterprise-level applications and data storage. Among many databases, Oracle database has the advantages of high availability, scalability, security and performance, so it is widely used in production environments. This article will focus on how to install the Oracle database on the Linux operating system.

1. Software preparation

Before starting to install the Oracle database, you need to prepare the corresponding software. First, you need a Linux operating system, such as Red Hat, CentOS, Ubuntu, etc. Here we take CentOS 7 as an example. Secondly, you need to download the installation file of the Oracle database, which can be obtained from the Oracle official website.

2. Installation steps

Install relevant dependency packages

Before installing the Oracle database, you need to install the relevant dependency packages first. In CentOS 7, it can be installed via the following command:

yum install -y binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat

Create user and user group

For security reasons, a specific user and user need to be created for the Oracle database Group. It can be created through the following command:

groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle

Install Oracle database

After downloading the installation file of the Oracle database, you need to unzip it first. In Linux systems, you can use the tar command, as shown below:

tar -xf oracle-database-xe-18c-1.0-1.x86_64.rpm.zip

After decompression, you can get a .rpm installation file. Execute the following command to install the Oracle database:

yum localinstall oracle-database-xe-18c-1.0-1.x86_64.rpm

During the installation process, you need to enter a password, which will be used for access to the system administrator account (SYS) and database administrator account (SYSTEM). Please note that the installation at this time is Oracle Express Edition, which limits the hardware resources and data storage used.

Set up the listener

After installing the Oracle database, you need to set up a listener to facilitate client access to the database. In Linux systems, you can use the netca command to set it. Execute the following command:

su - oracle
netca

Then, you can set it up according to the instructions, save and exit after the setting is completed.

Create Database

The last step is to create an Oracle database. In Linux systems, you can use the dbca command to create a database. Execute the following command:

su - oracle
dbca

Set according to the prompts, save and exit after completion.

3. Summary

Through the introduction of this article, readers can learn how to install the Oracle database on the Linux operating system. You need to prepare relevant software and dependent packages first, and then create relevant users and user groups. Next, unzip and install the Oracle database installation file, set the listener and create the database. In the actual application process, more attention needs to be paid to security and performance issues to ensure the stable and safe operation of the Oracle database.
