Continuous Delivery Using Jenkins

Let me introduce our Jenkins jobs. If Jenkins was not exist, we would suffer from HARD HARD build and deploy jobs.

First of all, we made our server list file. Because this is very often used by Jenkins deploy and restart jobs.
Add your Jenkins user key to my_name/.ssh/authorized_key on each server.
-Jenkins Server List Configure Job-

	CONFIG(){
	test -e $1 && cp $1 $1.old
	cat > $1 <<EOF
	192.28.255.111
	192.28.255.112
	EOF
	test -e $1.old && diff $1 $1.old|cat
	}
	CONFIG /usr/local/repository/prd/my_product.list

Next step, we build our project and make backup too.

-Jenkins Build Job-
Build our project by running maven.
  clean release:clean release:prepare package -P prd

And make backup directory.

	#This script is for jenkins build job
	OLD_DIR=$(date +"%Y_%m_%d_%H_%M_%S")
	REPO=/usr/local/repository/prd/my_product/
	BACKUP_DIR="/usr/local/repository/prd/my_product_backup"
	if [ -d "$BACKUP_DIR" ]; then
	mv $BACKUP_DIR/my_product $BACKUP_DIR/$OLD_DIR/
	fi
	mv $REPO $BACKUP_DIR/my_product/
	/usr/bin/rsync -acvz ${WORKSPACE}/target/deploy/ $REPO --delete

And run deploy job. Don't forget set post-build Actions. We set Build other projects(Jenkins Restart Job)
-Jenkins Deploy Job-

	LIST=/usr/local/repository/prd/my_product.list
	REPO=/usr/local/repository/prd/my_product
	DEST=/usr/local/app/
	sed -e "s/#.*//" -e "s/^\s*$//" $LIST | while read i; do
	echo "#### deploy -> $i ####"
	rsync -e 'ssh -o StrictHostKeyChecking=no' -acvz --delete --exclude="logs" $REPO my_name@$i:$DEST
	done
	sed -e "s/#.*//" -e "s/^\s*$//" $LIST

-Jenkins Restart Job-

	LIST=/usr/local/repository/prd/my_product.list
	COMMAND="sh /usr/local/app/my_product/bin/my_product_control.sh restart"
	sed -e "s/#.*//" -e "s/^\s*$//" $LIST | while read i; do
	echo "#### restart -> $i ####"
	ssh -o 'StrictHostKeyChecking=no' -2 -n my_name@$i $COMMAND
	done

Sometimes we need to revert our service. We use this job. Don't forget to set Build other projects(Jenkins Deploy Job) that it will execute Jenkins Restart Job.
-Jenkins Roll Back Job-

/usr/bin/rsync -acvz /usr/local/repository/prd/my_product_backup/my_product/ /usr/local/repository/prd/my_product/ --delete

[memo] jmagick 6.4.0 configure problem

I had to install jmagick 6.4.0. And I tried to install as the following.

	tar xvzf /opt/jmagick-6.4.0-src.tar.gz -C /opt
	chown -R root.root /opt/6.4.0
	cd /opt/6.4.0
	./configure --prefix=/opt/jmagick-6.4.0 --with-java-home=/opt/java/ --with-magick-home=/opt/imagemagick
	make all
	make install
	rm /opt/jmagick
	ln -s /opt/jmagick-6.4.0 /opt/jmagick

Jmagick dose not care "--with-java-home=/opt/java/". It just uses "/usr/bin/java javac javah jar".
So you need to link them to /usr/bin

#ln -s /opt/java/bin/java /usr/bin/java

[memo] svc: warning: unable to control file does not exist.

I solved this problem here.

The key is the following command.
# svscanboot &
