Installing Metacat requires a server running an SQL92 compliant database

| 254 |
3019
|

|
(Oracle 8i or Postgresql recommended) with at least 128MB RAM, and a Pentium III class

processor or higher. The amount of disk space required depends on the
|
| 256 |
|
|
size of your RDBMS tablespace (which should be at least 10 MB,
|
| 257 |
|
|
however Metacat itself requires only about 1 MB of free space after
|

On Ubuntu and other Debian-based Linux distributions, you can use the apt-get command

to install postgres:

Ant is a Java based build application similar to Make on UNIX systems.
|

|
|
It takes in installation parameters from a file in the root installation

directory named "build.xml". The Metacat CVS module contains a default

| 357 |
|
|
build.xml file that may require some modification upon installation. Ant

932
|
jones
|
should be installed on the system and the "ant" executable shell script
|
| 359 |

should be available in the users path. The latest metacat release was tested with

Ant 1.6.5. <!-- We note that the current build is

2182

not working with Ant 1.6.x, so you'll need to use an earler version. We have

<p>Tomcat will look for it's application files (war files) in a configured directory.
|
| 478 |
|
|
This is typically the <tomcat_home>/webapps directory, but your instance of Tomcat may
|
| 479 |
|
|
be configured to look in a different directory. We will refer to your Tomcat application directory
|
| 480 |
|
|
as <tomcat_app_dir>.</p>
|
| 481 |
|
|
|
| 482 |
|
|
<p>If desired, back up your existing war file with a date:</p>
|
| 483 |
|
|
<div class="code">sudo mv <tomcat_app_dir>/knb.war <tomcat_app_dir>/knb.war.<yyyymmdd></div>
|
| 484 |
|
|
|
| 485 |
|
|
<p>Copy the war file to the Tomcat applications directory:</p>
|
| 486 |
|
|
<div class="code">sudo cp knb.war <tomcat_app_dir></div>
|
| 487 |
4571
|
daigle
|
<p>Remove (or rename) the existing application directory:</p>
|
| 488 |
4637
|
daigle
|
<div class="code">sudo rm -rf <tomcat_home>/webapps/knb</div>
|
| 489 |
4571
|
daigle
|
<p> or </p>
|
| 490 |
4637
|
daigle
|
<div class="code">sudo mv <tomcat_home>/webapps/knb <tomcat_home>/webapps/knb.<yyyymmdd></div>
|
| 491 |
4571
|
daigle
|
<p>Restart Tomcat:</p>
|
| 492 |
|
|
<div class="code">sudo /etc/init.d/tomcat5.5 restart</div>
|
| 493 |
4637
|
daigle
|
<p>Tomcat will expand your war file into a new application directory at startup time.</p>

|
<p>Once you have successfully installed Metacat, there is one more step. Tomcat
|
| 497 |
|
|
(and Apache if you have Tomcat integrated with it) must be restarted. To do
|
| 498 |
|
|
this, login as the user that runs your tomcat server (often "tomcat"),
|
| 499 |
4637
|
daigle
|
go to <tomcat_home>/bin and type: </p>
|
| 500 |
4571
|
daigle
|
|
| 501 |
|
|
<div class="code">./startup.sh</div>
|
| 502 |
|
|
|
| 503 |
|
|
<p>In the Tomcat startup messages you should see something in the log file like:</p>
|
| 504 |
|
|
|
| 505 |
|
|
<div class="code">Metacat: [WARN]: Metacat (1.8.0) initialized. [edu.ucsb.nceas.metacat.MetaCatServlet]</div>
|
| 506 |
|
|
|
| 507 |
|
|
If you see that message Tomcat has successfully loaded the Metacat servlet.
|
| 508 |
|
|
Next, try to run your new servlet. Go to a web browser and type:</p>
|
| 509 |
|
|
|
| 510 |
|
|
<div class="code">http://yourserver.yourdomain.com/yourcontext/</div>
|
| 511 |
|
|
|
| 512 |
|
|
<p>You should substitute your context name for "yourcontext" in the url above.
|
| 513 |
|
|
If everything is working correctly, you should see a query page followed
|
| 514 |
|
|
by an empty result set. Note that if you do not have Tomcat integrated with
|
| 515 |
|
|
Apache you will probably have to type</p>
|
| 516 |
|
|
|
| 517 |
|
|
<div class="code">http://yourserver.yourdomain.com:8080/yourcontext/</div>
