使用Fastdfs V6.03，fastdfs-nginx-module V1.22， nginx-1.16.1进行编译，运行后nginx报错，报错 系统是CentOS Linux release 7.7.1908，gcc 4.8.5 信息如下： ` sudo journalctl -xe

这个反复编译了几遍，都是这样，搜也没搜到相关的内容，不知道是什么问题。

应该是环境问题导致的。 你 ldd nginx 看看使用到的动态库是否正确。 例如： ldd /usr/sbin/nginx 或者 ldd /usr/local/sbin/nginx 检查一下 libfastcommon.so 和 libfdfsclient.so 这两个动态库文件的路径是否正确。
