An extra blank between #! and /usr/ for the first line

not sure if this will make the script valid.

Someone reported that:

脚本执行如下： bash setup-obproxy.sh -n oceanbase-test1 --proxy-image oceanbase/obproxy-ce:4.2.1.0-11 -d obproxy-test obclusterPS：用/bin/bash执行> 以上shell脚本，用/bin/sh执行报错

Thank you so much for pointing this out!

Although there's no evidence showing that the spaces between #! and the interpreter would cause exception (SheBang - Wikipedia), we will remove them to align with conventional usage.
