rpm: relocations must begin with a /

Cause explanation: When installing the program using the rpm package provided by antdb, if you do not specify the installation path, it will be installed in the /opt/app/adb (or /opt/app/antdb) directory by default. However, customers generally require installation to the specified directory, so you can use the relocate option provided by the rpm command to adjust the default installation path to the specified directory (take the /data/sy/adb40sy/adb specified directory as an example).

sudo rpm -ivh adb-4.0.9ff827a8-10.el7.centos.x86_64.rpm --relocate=/opt/app/adb=$ADB_HOME

There should be no spaces between relocate and the configuration that follows. If spaces are present, the error message shown in the title is thrown Solution. Do not add spaces between relocate and value.
