After the configuration is complete, run

/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

The tracker can run successfully.
There are two possible problems.
1. The directory set by base_path does not exist. If this error is reported, create a directory according to base_path settings.
2. libevent-2.0.so.5 not found
If this cannot be found, confirm the installation location during installation.
Generally, this library will be installed in/usr/local/lib.
Our fdfs_trackerd will be searched in/usr/lib, so we use

ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5

Load the library to/usr/lib.
