How to set up software installation on CentOS systems using a secure remote repository
Overview:
In CentOS systems, installing software packages is a key operation. In order to ensure the security and stability of the software, we should use a secure remote warehouse to install and update the software. This article will introduce how to set up a secure remote warehouse in CentOS system and provide relevant code examples.
Step 1: Install and configure the yum plug-in
First, make sure your system has the yum plug-in installed. Use the following command to check and install:
sudo yum install yum-plugin-security
After installation, use the following command to open the yum configuration file:
sudo vi /etc/yum/pluginconf.d/security.conf
Modify the file content as follows:
[main] enabled = 1
Step 2: Set up a secure remote warehouse
First, create a new yum warehouse file. Create and open the file using the following command:
sudo vi /etc/yum.repos.d/security.repo
In the file, paste the following content:
[CentOS-Security] name=CentOS-$releasever - Security baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/updates/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
Instructions:
$releasever
is your CentOS version number, such as 7. $basearch
to your system architecture, such as x86_64. Step 3: Update the system and install software
First, update the list of software packages in the system using the following command:
sudo yum update
When installing the software package, use the following command to install it. For example, when installing nginx:
sudo yum install nginx
Check the security report using the following command:
sudo yum updateinfo list security
