Simply distributed index: precached 0 indexes - sphinx

Question

I have two simple indexes:
First, 01.conf:
searchd
{
listen = 9301
listen = 9401:mysql41
pid_file = /var/run/sphinxsearch/searchd01.pid
log = /var/log/sphinxsearch/searchd01.log
query_log = /var/log/sphinxsearch/query01.log
binlog_path = /var/lib/sphinxsearch/data/test/01
}
source base
{
type = mysql
sql_host = localhost
sql_db = test
sql_user = root
sql_pass = toor
sql_query_pre = SET NAMES utf8
sql_attr_uint = group_id
}
source test : base
{
sql_query = \
SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content \
FROM documents WHERE id % 2 = 0
}
index test
{
source = test
path = /var/lib/sphinxsearch/data/test/01
}
Second looks like first but with "02" instead "01" in filename and inside.
And distributed index in 00.conf:
searchd
{
listen = 9305
listen = 9405:mysql41
pid_file = /var/run/sphinxsearch/searchd00.pid
log = /var/log/sphinxsearch/searchd00.log
query_log = /var/log/sphinxsearch/query00.log
binlog_path = /var/lib/sphinxsearch/data/test
}
index test
{
type = distributed
agent = 127.0.0.1:9301:test
agent = 127.0.0.1:9302:test
}
And I try to use distributed index:
sudo searchd --config /etc/sphinxsearch/d/00.conf --stop
sudo searchd --config /etc/sphinxsearch/d/01.conf --stop
sudo searchd --config /etc/sphinxsearch/d/02.conf --stop
sudo searchd --config /etc/sphinxsearch/d/01.conf
sudo searchd --config /etc/sphinxsearch/d/02.conf
sudo indexer --all --rotate --config /etc/sphinxsearch/d/01.conf
sudo indexer --all --rotate --config /etc/sphinxsearch/d/02.conf
sudo searchd --config /etc/sphinxsearch/d/00.conf
Unfortunately I obtain next output:
...
using config file '/etc/sphinxsearch/d/00.conf'...
listening on all interfaces, port=9305
listening on all interfaces, port=9405
precached 0 indexes in 0.000 sec
Why?
And when I try to search something with distributed index (9305):
no enabled local indexes to search.
And mysql indexes are works perfectly if I use them with port 9301 and 9302 respectively. But searching in distributed index returns nothing.

UPDATE2
Hmm... It seems what problem in querying data from Sphinx. Also I renamed distributed index into test1. Next code works well.
# mysql -h 127.0.0.1 -P 9405
mysql> select * from test1 where match ('one|two');
+------+----------+
| id | group_id |
+------+----------+
| 1 | 1 |
| 2 | 1 |
+------+----------+
2 rows in set (0,00 sec)
I think what problem was in old version of sphinxapi.php what I used.

precached 0 indexes in 0.000 sec
Well that it self, is normal. There are no local indexes to 'precache'. A distributed index has no index files to 'load' or (pre)cache.
... but searchd should still be running at the end of that. I think searchd should start up ok.
Try also checking
/var/log/sphinxsearch/searchd00.log
might have some more.
Although I suppose its possible sphinx will not startup without any real indexes (ie cant have JUST distributed index), so could just add a fake index to that config.
