Projekt mspr@job1

How I move the MSPR site from job4 to job1

Preparation

• Install standard opensuse 12.1
• Add repositories pacman, nvidia, vlc
• Install the following packages

zypper install apache2 php5 hg apache2-mod_php5 php5-gd php5-devel php5-pear gcc-c++ boost-devel libapr1-devel libapr-util1-devel

• Install db2 express-c 9.7.4
• Create instance db2mspr
• Configure instance like db2inst4 on job4

db2 update dbm cfg using numdb 2 federated yes DFT_MON_BUFPOOL on DFT_MON_LOCK on \
 DFT_MON_SORT on DFT_MON_STMT on DFT_MON_TABLE on DFT_MON_UOW on \
 INSTANCE_MEMORY 524288 SHEAPTHRES 200000 INTRA_PARALLEL YES

• Create connect user db2inst2 (required because tables have this schema)
• Create loader user mspr (loads data from mspr web/xml pages)
• Clone mspr repository to /home/joachim/workspace/mspr (for scripts and docs)
• Install pdo for db2 (see howto in database/)
• Enable apache to access instance db2mspr (DB2INSTANCE in /etc/sysconfig/apache2, export?)
• Other settings in /etc/sysconfig/apache2
  • APACHE_SERVERADMIN="joachim.banzhaf@googlemail.com"
  • APACHE_SERVERNAME="banzhaf.homeip.net"
• Add line in /etc/apache2/listen.conf: "Listen 801"
• Install scripts for import and web
  • all in web/ except gen_* to /srv/www/htdocs, then move images/ to mspr/images
  • util/mspr-* to /usr/local/bin
  • database/ta_mqt_refresh.sh to /usr/local/bin
• edit proxy destination (add test port :801 to url)

cd /srv/www/htdocs
for i in image index mainframe naviframe titleframe; do sed -i 's/\(homeip.net\)/\1:801/' $i.php; done

• Create password file for db connection /etc/apache/db2inst2.passwd, chown root:mspr, chmod 640
• Create group mspr with members mspr, db2mspr, wwwrun

make mspr

wget http://ftp.halifax.rwth-aachen.de/apache//logging/log4cxx/0.10.0/apache-log4cxx-0.10.0.tar.gz
tar xzvf apache-log4cxx-0.10.0.tar.gz
cd apache-log4cxx-0.10.0
configure
make
sudo make install

if this fails, add #include <cstring> (and one time <cstdio>) in the failing cpp's

Test Installation

• restore database from last backup and logs from job4 and document steps (needs 30-100 GB)

db2 restore db mspr on /home/db2mspr
db2 restore db mspr logs logtarget `db2 get db cfg for mspr | grep SQLOGDIR | awk -F '= ' '{print $2}'`
db2 rollforward db mspr to end of logs and stop
db2 activate db mspr

• check db settings are the same as on job4 (should be ok)
• Create portforward public :801 to job1:801

next task:

• Check if pages show correct results
• Setup cron for data imports
• Testrun for data import (check home directory requirement for mspr)

Production Switch

• disable update on job4
• restore db again
• edit proxy destination (remove test port :801 from url)

cd /srv/www/htdocs
for i in image index mainframe naviframe titleframe; do sed -i 's/:801//' $i.php; done

• test again
• remove public :801 forward
• forward public :80 to job1:80
• make apache listen to :80 instead of :801
• final tests
