Then you can just run irohad command.
B) Using Iroha with RocksDB:
Instead of postgres you can use RocksDB. In example directory there is sample config, which is using RocksDB, but path to database must be changed, e.g.:
sed -i 's_/path/to/wsv/folder_/home/rocksdb_g' example/config.sample
The next step is to use that config when running irohad:
./build/bin/irohad \
--config $PWD/example/config.sample \
--keypair_name $PWD/example/node0 \
-genesis_block $PWD/example/genesis.block \
-reuse_state
