1. Reasons for error reporting

/usr/local/rocketmq/bin/runserver.sh: 70: [[: not found
Unrecognized option: -Xlog:gc*:file=/dev/shm/rmq_srv_gc_%p_%t.log:time,tags:filecount=5,filesize=30M
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

2. Solution:

Use vim to edit the runserver.sh file in  Edit/usr/local/rocketmq/bin/

3. Error reason

Since the java version installed on the machine is 1.8
But there is an error of unknown reason in the java version judgment on line 70 in the /usr/local/rocketmq/bin/runserver.sh file
This led to the execution of the java 9+ version of the command
Therefore, you only need to comment the judgment and commands of the java 9+ version.

And vice versa, if the java version installed on the machine is 11
Then only need to comment the judgments and commands of the java 1.8 version
