CentOS VPS tutorial (3) YUM source configuration

CentOS VPS tutorial (3) YUM source configuration on the server may require installation of many software. To build a blog, you usually need a web server that supports PHP, such as Apache and Nginx, and a relational database such as MySQL. Installing software for these classes may take a long time, including many configuration, initialization, and dependency problems. You may also need to compile some software by yourself. We can use the YUM package management software that comes with CentOS to manage the installed software, making it much easier to install, update, and delete the software. (Each Linux release usually has its own package management software, such as apt of Ubuntu) YUM's software management relies on the YUM source set in the configuration file, these YUM sources are usually managed by some companies and organizations. We can use these sources to find the software we need to install. To add a YUM source, CentOS VPS usually comes with some default YUM sources. You can view/etc/yum. repos. d/directory, 1 $ ls/etc/yum. repos. d/to view the default sources. Each *. repo file indicates a YUM source, which describes the source name, address, whether to start, check, and other information. You can add a source file *. repo under this directory.
