1 How to run a pruning node with leveldb
3 Pruning nodes use a lightweight database to store address histories.
4 Only unspent coins are kept in that database; spent outputs are
7 As of November 2013 all public servers operate this way.
8 Please see HOWTO.md for more detailled information. The following is a
10 __________________________________________________________
13 Install version 0.4.4.6u4 or higher.
14 __________________________________________________________
16 2. Install python-leveldb:
18 Starting at Ubuntu 12.10 you can use apt to install leveldb. If you
19 rather stay on 12.04 LTS you can use the backport and add
20 "deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe"
21 to your sources file. Install the package with:
23 sudo apt-get install python-leveldb
25 alternatively build yourself, see
26 http://code.google.com/p/py-leveldb/
28 http://peter-hoffmann.com/2011/installation-leveldb-ubuntu-python.html
29 make sure you have libtool, automake and pkg-config
31 __________________________________________________________
33 3. edit /etc/electrum.conf :
39 path = /path/to/your/database
42 ______________________________________________________________
44 4. catch up with the blockchain.
46 In order to speed up the initial catch_up phase, it is recommended to
47 locate your database in shared memory:
49 path = /run/shm/electrum_db
51 Once your server has finished catching up, copy your database to disk
52 and update the path in /etc/electrum.conf
54 During the catch_up phase, you can interrupt the server with Ctrl-C;
55 it will safely write the current status in the database and exit.
57 _________________________________
61 Once the server is synchronized, it will listen to ports, and the
62 normal way to stop it is to use the 'stop' script. This script will
63 wait until the database is closed.
65 Other commands are available:
67 ./server info : view connections
68 ./server load : view the size of the queue
71 ______________________
74 * if your server or novacoind is killed because is uses too much
75 memory, configure novacoind to limit the number of connections
77 * if you see "Too many open files" errors, you may need to increase
78 your user's File Descriptors limit. For this, see
