[SUN] Apache 2.0.43 / Tomcat 4.1.12 / mod_jk for Solaris 8 (SPARC)

Apache 2.0.43 / Tomcat 4.1.12 / mod_jk for Solaris 8 (SPARC)

(last updated 11/05/2002)

————————————————————————-

First, you need a sane build environment. In the open source world, that means

GNU tools, not the tools included with a Sun Dev cluster install. Also make sure

you’ve installed the Sun Solaris 8_Recommended patch cluster.

You’ll also need openssl and openssh installed. I’m assuming here that if you

have a Sun server and you have root access to it that you have some basic

familiarity with system administration and know your way around a UNIX

command line.

So, bop on over to sunfreeware.com, pick your OS, and grab the following GNU

tools in Sun package format:

autoconf

automake

binutils

gcc (I used version 2.95.3)

glib

gzip

libtool

make

tar (don’t use the tar included with Solaris…make sure GNU tar is first in your

path)

wget

zlib

Install all of the packages listed above. Note that you’ll need to install gzip first, as

the other packages are compressed. The gzip package is not.

Apache + Tomcat is five major steps: build/install Apache, install JDK,

build/install Tomcat, build/install a connector, configure. Since Tomcat is 100%

Java, we’ll use the binary install instead of having to deal with ant. I spend more

time with Red Hat Linux than I do with Solaris, so my preference is to put things

in /usr/local. Die-hard Solaris folks will need to substitute /opt, /var, or whatever

as needed to suit their own preferences. Paths, in this scenario, don’t have

much effect as long as you can guarantee that they are consistent.

Build/Install APACHE

=====================

grab Apache source from a mirror. You want version 2.0.43. The filename is

httpd-2.0.43.tar.gz.

unpack it

read INSTALL file for instructions

build apache with: ./configure –prefix=/usr/local/apache2 –enable-ssl —

enable-module=so

If you see a message that says “configuring package in srclib/apr now” and the

build process seems to hang for several minutes, leave it alone, it will continue

after a bit.

when configure completes, run make.

when make completes, run make install.

You should now have an Apache instance in /usr/local/apache2. Verify

config: /usr/local/apache2/bin/apachectl configtest

If you get a “Syntax OK” message, startup

Apache: /usr/local/apache2/bin/apachectl start

Verify Apache is running: http://some.server.name You should see the Apache

welcome page

NOTE: Apache2 uses a shorthand notation for the group ID in httpd.conf. If you

have problems getting Apache2 to start on Solaris 8 from a default install, check

the Apache error log (/usr/local/apache2/logs/error_log) for an error message.

If you see one that says something like “[alert] (22)Invalid argument: setgid:

unable to set group id to Group 4294967295″ then edit httpd.conf, and change the

line that says “Group #-1” to “Group nobody” then start/restart

Apache. The

Solaris kernel has difficulty with the “#-1” shorthand notation if the Group ID

(gid)

is over 60000 for the group nobody, which it is in Solaris 8 64-bit.

Install JDK

=====================

go to java.sun.com and download J2SE for Solaris:

http://java.sun.com/j2se/1.4.1/download.html Note that if you have a

64-bit

Solaris install, you need to install the 32-bit J2SE first, then install the 64-bit J2SE.

I prefer the SDK versions over the JRE versions.

Install the 32-bit J2SE, and, if needed, the 64-bit J2SE. The 64-bit install simply

overwrites some files and installs some new ones into the same location used

for the 32-bit install, so do the 32-bit install first.

Set JAVA_HOME as an environment variable, pointing to the location of the J2SE

you just installed.

Build/Install TOMCAT

=====================

grab the Tomcat binary package for 4.1.12. Get it here:

http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.12/bin/jakarta-

tomcat-4.1.12.tar.gz

unpack it to /usr/local. You should end up with /usr/local/jakarta-tomcat-4.1.12

add a symbolic link: ln -s /usr/local/jakarta-tomcat-4.1.12 /usr/local/tomcat

set CATALINA_HOME as an environment variable, pointing to /usr/local/tomcat

startup Tomcat to test your installation: /usr/local/tomcat/bin/startup.sh. Verify

the Tomcat examples are available at http://some.server.name:8080/examples

Build/Install Connector

=======================

The two connectors (JK and JK2) are different; JK2 is a complete rewrite of the

earlier JK/AJP13 protocol. We’ll cover building JK, with JK2 to come later.

Building JK Connector

=======================

NOTE: you can get a JK binary for Solaris 8 here:

http://jakarta.apache.org/builds/jakarta-tomcat-

connectors/jk/release/v1.2.0/bin/solaris8/. The version there was compiled

against Apache 2.0.42 and should be compatible with 2.0.43. You are welcome to

skip building JK from source and use the binary instead, but if you would rather

build from source, here’s how to do it:

Grab the connector source from the Jakarta site:

http://jakarta.apache.org/builds/jakarta-tomcat-

connectors/jk/release/v1.2.0/src/jakarta-tomcat-connectors-jk-1.2.0-src.tar.gz

Unpack it to /usr/local/src/

From this point on, CONNECTOR_HOME = /usr/local/src/jakarta-tomcat-

connectors-jk-1.2.0-src

cd CONNECTOR_HOME/jk/native. Be sure to READ the file named BUILDING.

run the buildconf script: ./buildconf.sh

you may see some error messages about aclocal and autom4te…these can be

ignored.

run the configure script: ./configure –with-

apxs=/some/path/to/apache2/bin/apxs

run make

the mod_jk.so file will be in CONNECTOR_HOME/jk/native/apache-2.0. Copy it to

your Apache modules directory.

Final Configuration

=======================

NOTE: these steps will allow access to the Tomcat examples via Apache on port

80. Successful use of the examples on port 80 shows that mod_jk is working

correctly, since Tomcat is configured to run on port 8080 by default for HTTP

requests.

Edit server.xml in CATALINA_HOME/conf.

look for a line that says “Server” and has a port of 8005. Add the following

directly

below:

<Listener className=”org.apache.ajp.tomcat4.config.ApacheConfig”

modJk=”/usr/local/apache2/modules/mod_jk.so” />

in the Host container add the following Listener directive (yes, it looks very similar

to the one above):

<Listener className=”org.apache.ajp.tomcat4.config.ApacheConfig”

append=”true” forwardAll=”false”

modJk=”/usr/local/apache2/modules/mod_jk.so” />

change the name parameter in the Host directive to your apache ServerName

(the default is localhost)

Edit httpd.conf in APACHE_HOME/conf.

– make sure your ServerName matches the name=”” parameter in your tomcat

Host element in server.xml

– add the following line at the very end:

Include /usr/local/tomcat/conf/auto/mod_jk.conf

Note: the mod_jk.conf file gets created by tomcat when tomcat starts. It gets

created every time tomcat starts. So, if you have your server.xml configured, you

can ignore httpd.conf (in most cases) except to add the Include directive for

mod_jk.conf. You don’t need to create or edit mod_jk.conf. Click here for a

sample mod_jk.conf file generated automatically by tomcat on each startup.

Create a file in CATALINA_HOME/conf/jk called workers.properties. That file

should look like this:

# BEGIN workers.properties

worker.list=ajp13

worker.ajp13.port=8009

# change this line to match apache ServerName and Host name in server.xml

worker.ajp13.host=localhost

worker.ajp13.type=ajp13

# END workers.properties

Startup tomcat: $CATALINA_HOME/bin/startup.sh

Wait at least 10 seconds for tomcat to finish. Start

apache: /usr/local/apache2/bin/apachectl start

Verify examples at http://localhost:8080/examples. On success, tomcat is

working correctly.

Verify examples at http://localhost/examples. On success, apache is working

correctly, and JSP and servlet requests are being passed to tomcat.
