```

Modify the storage cluster configuration file with the following command:

sudo vim /opt/leofs/current/etc/leo_storage_cluster.conf

Replace the configuration file content with the following:

[item1]
# storage node IP address
ip = 127.0.0.1

# storage node port
port = 10010

# number of replicas
replica = 2

[item2]
# storage node IP address
ip = 127.0.0.1

# storage node port
port = 10011

# number of replicas
replica = 2

Save and close the file.

Modify the manager node configuration file with the following command:

sudo vim /opt/leofs/current/etc/leo_manager.conf

Replace the configuration file content with the following:

[manager_master]
