Your log reports here this process fails since some previous process is using the port…
Creating Server TCP listening socket 127.0.0.1:12000: bind: Address already in use
17:20:43 web.1 | socket.error: [Errno 98] Address already in use
Maybe shutdown everything with this:
frappe@erpnext:~/frappe-bench$ sudo supervisorctl stop all
frappe-bench-frappe-schedule: stopped
frappe-bench-frappe-default-worker-0: stopped
frappe-bench-frappe-long-worker-0: stopped
frappe-bench-frappe-short-worker-0: stopped
frappe-bench-frappe-web: stopped
frappe-bench-node-socketio: stopped
frappe-bench-redis-queue: stopped
frappe-bench-redis-cache: stopped
frappe-bench-redis-socketio: stopped
This means redis is still running
frappe@erpnext:~/frappe-bench$ redis-cli ping
PONG
So shutdown redis with this:
frappe@erpnext:~/frappe-bench$ redis-cli shutdown
frappe@erpnext:~/frappe-bench$ redis-cli ping
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Now try ‘bench start’ and check for an error free startup.
Or alternatively try this (to startup a prod server instance):
frappe@erpnext:~/frappe-bench$ sudo supervisorctl start all
frappe-bench-frappe-schedule: started
frappe-bench-frappe-default-worker-0: started
frappe-bench-frappe-long-worker-0: started
frappe-bench-frappe-short-worker-0: started
frappe-bench-frappe-web: started
frappe-bench-node-socketio: started
frappe-bench-redis-queue: started
frappe-bench-redis-cache: started
frappe-bench-redis-socketio: started
These logs may give you an idea of the problem:
frappe@erpnext:~/frappe-bench$ ls -al logs | grep redis
