   @liangyepianzhou What's the need to run `source conf/standalone.conf`? `conf/standalone.conf` is just the configuration file that is read by pulsar standalone starter. For example,
   
   ```bash
   bin/pulsar-daemon start standalone
   ```
   
   It will read `conf/standalone.conf` as the configuration file of pulsar standalone by default.
   
   Or you can run
   
   ```bash
   PULSAR_STANDALONE_CONF=conf/standalone-2.conf bin/pulsar-daemon start standalone
   ```
   
   The it will read `conf/standalone-2.conf` as the configuration file of pulsar standalone by default.
   
   `conf/xxx.conf`s are all Java properties files, not a shell file that contains environment variables. Running `source conf/standalone.conf` is meaningless.
   
   In shell script, the variable assignment should not have any space around the `=`:
   
   ```bash
   VARIABLE=hello # OK
   VARIABLE = hello # Error
   ```
   
   But in Java properties file, spaces around `=` are okay.
