RH 7.2 step by step

Here are the step by step instructions I promised way back when. I
didn’t get a chance to write it up until now. It’s off the top of my
head, so I do apologize if I neglected a step or two. Please let me
know of any mistakes, so I can update the instructions on
documenations… Thanks.

I also attached the file.


1)Install Redhat 7.2

2)Remove apache in distributed Redhat 7.2
To a get a list, run this command:

rpm -qa | grep apache


then run

rpm -e apacheconf-0.8.1-1
rpm -e apache-manual-1.3.22-2
rpm -e apache-devel-1.3.22-2
rpm -e apache-1.3.22-2

3)Download mod_perl and apache source. I put the source in /temp. Unzip
and untar the source.

gunzip -c apache_1.13.9.tar.gz | tar xvf -
gunzip -c mod_perl-1.26.tar.gz | tar xvf -

4)To install Apache with mod_perl statically compiled.

cd into the mod_perl directory and run the following commands to
configure mod_perl for apache install:

  cd /temp/mod_perl-1.26
        perl Makefile.PL \
         APACHE_SRC=../apache_1.13.9/src \
          NO_HTTPD=1 \
          USE_APACI=1 \
          PREP_HTTPD=1 \
           EVERYTHING=1 \
           make install

cd into apache source directory. To install apache, run the following
cd /temp/apache_1.3.19/
./configure --prefix=/usr/local/apache
–activate-module=src/modules/perl/libperl.a \

  1. Download and install CPAN
    unzip and untar source and cd into CPAN source directory.
    follow these commands to install:

gunzip -c CPAN-1.59.tar.gz | tar xvf -
cd /temp/CPAN*
perl Makefile.PL
make install

  1. Install Mason manually as CPAN doesn’t seem to download and install
    it automatically.
    unzip and untar source and cd into Mason directory.

gunzip -c HTML-Mason-1.04.tar.gz | tar xvf -
cd /temp/HTML-*
perl Makefile.PL
make install

  1. Download and unpackage RT.

gunzip -c rt.tar.gz | tar xvf -

  1. Get dependent modules.
    cd /temp/rt-2-0-9/
    make testdeps
    make fixdeps

  2. Configure preliminarily apache.

a)In http.conf, change the following lines. They are in this order,
but not juxtaposed vertically. Do a search
make the changes.

ServerType stand
ServerRoot "/usr/local/apache"
MinSpareServers 5
MaxSpareServers 20
StartServers 8
MaxClients 150
MaxRequestsPerChild 100
Listen 80
Port 80
User apache
Group apache
ErrorLog /var/log/httpd/error.log
CustomLog /var/log/httpd/access_log combined

b)Make log directories.
mkdir -p /var/log/httpd/error.log /var/log/httpd/access_log
chown -R apache:apache /var/log/httpd/error.log

  1. Create user rt.

groupadd -g 35 rt
useradd -m -d /home/rt -u 4040 -g 35 rt

  1. Set root password for MySQL database.


username: root
password: 123456

The syntax is as follows:

/mysql/admin -u root password ‘123456’

  1. Install RT

a) Make changes to Makefile
cd /tmp/rt-2-0-9
vi Makefile
for these entries

RT_PATH = /opt/rt2
RT_LOG_PATH = /var/log/rt2
DB_TYPE = Mysql
DB_HOME = /usr/bin/mysql
DB_DBA = root
DB_DBA_PASSWORD = "123456"
WEB_USER = apache
WEB_GROUP = apache
c) mkdir -p /var/log/rt2
chown -R root:rt /var/log/rt2
chmod 755 /var/log/rt2

b) Install rt: build database and install rt files.

make install

  1. Set up Sendmail
    a) configure Sendmail to receive connections outside of localhost.
    Sendmail from Redhat
    by default doesn’t allow outside email.
    change the mc file

vi /etc/mail/sendmail.mc
DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA’)
<-------------dnl this entry
run the command

m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

vi /etc/aliases
rt-comment: “|/opt/rt2/bin/rt-mailgate --queue general --action
comment” <----------add the following entry
rt: “|/opt/rt2/bin/rt-mailgate --queue general --action
correspond” <----------add the following entry
14) Configure config.pm file for rt
Let’s say our domain is wheats.com.

a) Change the following in the file, accordingly.

  1. Make sure user rt can access and manipulate database.

username: root
password: 123456

mysql -u root -p
GRANT ALL ON rt2.db.* To rt@localhost Identified By "123456"
16) Setup rt to access by Apache.
IP address of rt machine:
Only machines in wheats.com domain will allow be accessed.

In the httpd.conf file in /usr/local/apache/conf

a) Add the following entries, accordingly.

#NameVirtualHost *

DocumentRoot /opt/rt2/WebRT/html
ServerName dummy.wheats.com
PerlModule Apache::DBI
PerlFreshRestart On
PerlRequire /opt/rt2/bin/webmux.pl

SetHandler perl-script
PerlHandler RT::Mason
Order allow,deny
Allow from *.wheats.lbl.gov

  1. Add apache to run scripts.
    cp /usr/local/apache/bin/apachect1 /etc/init.d/
    ln -s /etc/init.d/apachect1 /etc/rc3.d/S99httpd

  2. Reboot the machine. I hope everything works. Please, please let me
    know if things don’t go right or how
    I can make things clearer.
