h2. 1 Make sure MySQL is installed
6
7
Follow the instructions in the "Leginon install guide":http://emg.nysbc.org/documentation/leginon/bk02ch04s07.php.
8
 
9
Also install phpMyAdmin found under "Other Tools" on "this page":http://emg.nysbc.org/documentation/leginon/bk02ch04s08.php.
10
Note that phpMyAdmin version 2.11.10 works with older versions of PHP (that we happen to use).
11
12
h2. 2 Dump tables from cronus4 to a local file
13
14
This will grab the actual data that we use so you can play with it.
15
Log into cronus3 so that you can access cronus4.
16
17
<pre>
18
$ ssh cronus3
19
</pre>
20
21
Use mysqldump to get any table data that you want as in the example below. 
22
Cronus4 is the host. 
23
We do not lock the tables because we don't have permission to. 
24
"project" is the name of the database and "login" is the name of the Table.
25
We make up a file name for the data to dump to.
26
27
<pre>
28
$ mysqldump -h cronus4 -u usr_object --skip-lock-tables project login > ProjectLogin.sql
29
</pre>
30
31 2 Amber Herold
More info on mysqldump is "here":http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html#option_mysqldump_tables.
32
33 1 Amber Herold
Exit cronus3 when you are done dumping tables and load the dump files into your database.
34
If you followed the instructions for setting up MySQL in the Leginon Install guide, you have already created dbemdata and projectdata databases.
35
If you don't have them, create them first.
36
37
<pre>
38
mysql -u root projectdata < ProjectLogin.sql
39
</pre>
40
41
h2. 3 Modify Config.php
42
43
It should look like this:
44
45
<pre>
46
// --- Set your leginon MySQL database server parameters
47
48
$DB_HOST        = "localhost";
49
$DB_USER        = "usr_object";
50
$DB_PASS        = "";
51
$DB             = "dbemdata";
52
53
// --- XML test dataset
54
$XML_DATA = "test/viewerdata.xml";
55
56
// --- Project database URL
57
58
$PROJECT_URL = "project";
59
$PROJECT_DB_HOST = "localhost";
60
$PROJECT_DB_USER = "usr_object";
61
$PROJECT_DB_PASS = "";
62
$PROJECT_DB = "projectdata";
63
</pre>
64
65
h2. 4 Populate your databases automagically
66
67
Point your web browser to http://localhost/myamiweb/.
68
Navigate to the Administration page and then to the ProjectDB page. 
69
70
Doing this will populate your database with the schema defined in myami/myamiweb/project/defaultprojecttables.xml.
