I have two model
1) Server Model : conneted to remote database which is stored on server
2) Local Host : connected to my pc database is stored in on pc.
On linux I can open two msql workbench instances. The second instance can be opened by running the executable file directly.
Find where the executable file is located by running
ps -ef | grep workbench
