3、echo $LD_LIBRARY_PATH

/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64/dyninst:/opt/rh/devtoolset-8/root/usr/lib/dyninst:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64/dyninst:/opt/rh/devtoolset-8/root/usr/lib/dyninst:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/opt/rh/devtoolset-8/root/usr/lib64/dyninst:/opt/rh/devtoolset-8/root/usr/lib/dyninst:/opt/rh/devtoolset-8/root/usr/lib64:/opt/rh/devtoolset-8/root/usr/lib:/usr/local/boost/lib:/usr/local/lib:/usr/local/lib64:/usr/local/boost/lib:/usr/local/lib:/usr/local/lib64

4、ls -al /usr/local/lib64/libprotobuf.so.3.15.8.0

-rwxr-xr-x 1 root root 10563720 May 25 18:47 /usr/local/lib64/libprotobuf.so.3.15.8.0

启动php-fpm后，skywalking无法收到数据。文件都有，可为什么会报上面cannot open shared object file: No such file or directory错误呢

谢谢
