1.Install tomcat

2.Install mongoDB

3-6. Deploy the project (java parts)

7. Install LVS + Keepalived

8. Install XfreemFS

9. NTP - sync the time

Our project website: http://10.42.0.246:10001/cloudproject To visit out of CS-Dpt. Network Plz ssh username@gatekeeper.cs.hku.hk And type ssh -L 12345:10.42.0.246:10001 -g student@202.45.128.135 Then you can visit http://gatekeeper.cs.hku.hk:12345/cloudproject

Our Github source code: https://github.com/JiCaiCai/cloudproject

1.Install tomcat:

Download http://mirrors.devlib.org/apache/tomcat/tomcat-7/v7.0.53/bin/apache-tomcat-7.0.53.zip

2.Install mongoDB:

a.sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

b.echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

c.sudo apt-get update

d.sudo apt-get install mongodb-org

3.Config data base connection:

config cloudproject/WEB-INF/classes/config.properties file:

sourceImagePath=/home/hduser/ximages/

mongoDB.fingerprint=mongodb://10.42.0.117/photo.fingerprint

mongoDB.output=mongodb://10.42.0.117/photo.out

mongoDB.searchResult=mongodb://10.42.0.117/photo.searchResult

mongoDB.statistic=mongodb://10.42.0.117/photo.statistic

collection.searchResult=searchResult

collection.fingerprint=fingerprint

HOST=10.42.0.117

dbName=photo

4.Copy cloudproject folder into tomcat webapps folder

5.Execute /home/hduser/apache-tomcat-7.0.53/bin/startup.sh to run Tomcat server.

6.Visit localhost:8080/cloudproject in the browser.

7. Install LVS + Keepalived on Student37 and Student 55

sudo apt-get install ipvsadm

sudo apt-get install keepalived

The server config file is

ync_group VG1 {

group {

    VI_1

}

}

vrrp_instance VI_1 {

state MASTER

interface xenbr0

virtual_router_id 51

priority 100

advert_int 1

authentication {

    auth_type PASS

    auth_pass 1111

}

virtual_ipaddress {

    10.42.0.246

}

}

virtual_server 10.42.0.246 10001 {

delay_loop 6

lb_algo rr

lb_kind DR

persistence_timeout 300

protocol TCP



real_server 10.42.0.130 10001 {

    weight 500

    TCP_CHECK {

        connect_timeout 3

    }

}

real_server 10.42.0.131 10001 {

    weight 100

    TCP_CHECK {

        connect_timeout 3

    }

}

real_server 10.42.0.184 10001 {

    weight 100

    TCP_CHECK {

        connect_timeout 3

    }

}

real_server 10.42.0.185 10001 {

    weight 100

    TCP_CHECK {

        connect_timeout 3

    }

}

real_server 10.42.0.118 10001 {

    weight 100

    TCP_CHECK {

        connect_timeout 3

    }

}

real_server 10.42.0.119 10001 {

    weight 100

    TCP_CHECK {

        connect_timeout 3

    }

}

}

Note, the student55 should change to BACKUP

For client machine, need to add lines as following to rc.local to bind the VIP and stop the ARP responding

ifconfig lo:0 10.42.0.246 netmask 255.255.255.255 broadcast 10.42.0.246 up

sudo route add -host 10.42.0.246 dev lo:0

sudo echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore

sudo echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce

sudo echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore

sudo echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce

8. Install XfreemFS

Add a file named xfs.list at /etc/apt/sources.list.d as following

(For Client)

deb http://download.opensuse.org/repositories/home:/xtreemfs/xUbuntu_10.04 ./

(For Server)

deb http://download.opensuse.org/repositories/home:/xtreemfs/xUbuntu_12.04 ./

wget -q http://download.opensuse.org/repositories/home:/xtreemfs/xUbuntu_13.10/Release.key -O - | sudo apt-key add -

sudo apt-get update

sudo apt-get install xtreemfs-client

sudo apt-get install xtreemfs-serve

Then, do some config work.

At server side:

The META,DIR,OSD server should execute

/etc/init.d/xtreemfs-dir start

/etc/init.d/xtreemfs-mrc start

/etc/init.d/xtreemfs-osd start

At client side:

The client should use

mount.xtreemfs student37/ximages ~/ximages # mount the fs

9. NTP

Each machine should sync the time with a centred server and we choose student37 as this server.

For each installation

sudo apt-get install ntp

Student37 is allowed sync with up-level server *.ubuntu.pool.ntp.org

Other clients are only allowed sync with student37

The configuration of student37 is as following

driftfile /var/lib/ntp/ntp.drift

#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats

filegen loopstats file loopstats type day enable

filegen peerstats file peerstats type day enable

filegen clockstats file clockstats type day enable
