Description of problem: pcre社区已经停止维护： The older, but still widely deployed PCRE library, originally released in 1997, is at version 8.45.

Version 8.45 is expected to be the final release of the older PCRE library, and new projects should use PCRE2 instead. 当前Anolis OS 23中仍有如下软件包对pcre有依赖，需要分析是否可以迁移到依赖pcre2。 glibc2 grep nginx nmap slang-slsh Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
