改用CentOS7 yum源

Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

Repository epel is listed more than once in the configuration
Loading mirror speeds from cached hostfile
Package 1:nodejs-16.18.1-3.el7.x86_64 already installed and latest version
Nothing to do
