Standalone Tomcat7 re-deployment for Oxalis

Its already a third time when I have to re-deploy Tomcat due to application, environment or even Tomcat issues.

Current system/situation:
- Centos 6.5
- Running Tomcat6, Tomcat7 (7.0.37). Integrated
- Difi Oxalis cant run in the same 'house' with Difi XML validator
- Difi Oxalis AS2 has mime issues running Tomcat 7.0.37-7.0.40
- Java available: 1.6, 1.7 (both JDK's and JRE's). Ref "update-alternatives --config java"

Quick cheat-sheet on how to re-deply Tomcat7 (7.0.55) with Oxalis config:

# cd /opt/
# wget
# tar -xvf apache-tomcat-7.0.55.tar.gz
# mv apache-tomcat-7.0.55 tomcat7
# cd tomcat7
# export TOMCAT_HOME=/opt/tomcat7
# export CATALINA_HOME=/opt/tomcat7
# ant -Dtomcat.home=$TOMCAT_HOME -f /root/metro/metro-on-tomcat.xml install
# nano /opt/tomcat7/tomcat-users.xml

   <user username="manager" password="******" roles="manager"/>

# nano /opt/tomcat7/web.xml
    -- comment out all the welcome lines. cocoon needs this

# cp /var/lib/tomcat7/webapps/*.war /opt/tomcat7/webapps/
# nano /opt/tomcat7/server.xml

  <connector port="8443" protocol="HTTP/1.1" sslenabled="true">
   maxThreads="150" scheme="https" secure="true"              
   clientAuth="false" sslProtocol="TLS" sslEnabledProtocols="TLSv1,SSLv3,SSLv2Hello" keystoreFile=".keystore" keyAlias="tomcat"  keystorePass="******" />

# cp /usr/share/tomcat7/ssl_tomcat /opt/tomcat7/ -R
# cp /usr/share/tomcat7/.keystore /opt/tomcat7/
# sh bin/

--- edit or create tomcat startup script

# nano /etc/init.d/tomcat7

  # description: Tomcat Start Stop Restart
  # processname: tomcat
  # chkconfig: 234 20 80
  export PATH

  # Define the tomcat username

  case $1 in
    sh $CATALINA_HOME/bin/
    sh $CATALINA_HOME/bin/
    sh $CATALINA_HOME/bin/
    sh $CATALINA_HOME/bin/
         if [ -f "/var/run/${NAME}.pid" ]; then
 #           status ${NAME}
 #           RETVAL="$?"   
             read kpid < /var/run/${NAME}.pid
             if [ -d "/proc/${kpid}" ]; then
                 echo "${NAME} (pid ${kpid}) is running..."
             pid="$(/usr/bin/pgrep -d , -u ${TOMCAT_USER} -G ${TOMCAT_USER}  java)"
             if [ -z "$pid" ]; then
 #               status ${NAME}     
 #               RETVAL="$?"
                 echo "${NAME} is stopped"
             echo "${NAME} (pid $pid) is running..."
         sh $CATALINA_HOME/bin/      
         echo "Usage: $0 {start|stop|restart|condrestart|try-restart|reload|force-reload|status|version}"
  exit 0   

# chmod 755 /etc/init.d/tomcat7
# chkconfig --add tomcat7
# chkconfig --level 234 tomcat7 on
# chkconfig --list tomcat7
# /etc/init.d/tomcat7 restart

Some explanations of the cheat-sheet:
- Tomcat7 was deployed as current stable Centos compatible version (7.0.37)
- wget url - download using preferred server
- Metro requirement - ref to Oxalis installation description, its just one .jar file stored in endorsed dir, it might as well be just copied from your old Tomcat installation
- passwords in '*******' - dont forget to replace with your passwords
- cocoon installation is optional
- please note that Tomcat 7.0.55 cant locate your .keystore and you have to define its path manually using tags "keystoreFile" and "keyAlias" which where not needed before
- sslEnabledProtocols is another fix related to SSLv2 beeing disabled in Java7 and OpenSSL 1.0.0+
- ssl_tomcat folder is optional
