OpenStack configuration

Controller/Network node and Compute nodes were installed according to OpenStack official documentation

We created one project for each EGI FedCloud VO supported, a router and various nets and subnets obtaining the following network topology:

We mount the partitions for the glance and cinder services (cinder not in the fstab file) from 192.168.61.100 with nfs driver: 

yum install -y nfs-utils
mkdir -p /var/lib/glance/images
cat<<EOF>>/etc/fstab
192.168.61.100:/glance-egi /var/lib/glance/images     nfs defaults      
EOF
mount -a

We use some specific configurations for cinder services using the following documentation cinder with NFS backend.

EGI FedCloud specific configuration

To change the dashboard logo, copy the right svg file in /usr/share/openstack-dashboard/openstack_dashboard/static/dashboard/img/logo-splash.svg

For publicly exposing on https some OpenStack services do not forget to create the files /etc/httpd/conf.d/wsgi-nova,neutron,glance,cinder.conf and set the corresponding endpoints before to restart everyhting.

Install FedCloud BDII

(See EGI integration guide and BDII configuration guide) Installing the resource bdii and the cloud-info-provider in egi-cloud-ha (with CMD-OS repo already installed): 

yum -y install bdii cloud-info-provider cloud-info-provider-openstack

Customize the configuration file /etc/cloud-info-provider/sample.openstack.yaml with the local sites' infos, and rename it /etc/cloud-info-provider/openstack.yaml

Customize the file /etc/cloud-info-provider/openstack.rc with the right credential, for example: 

export OS_AUTH_URL=https://egi-cloud.pd.infn.it:443/v3
export OS_PROJECT_DOMAIN_ID=default
export OS_REGION_NAME=RegionOne
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_IDENTITY_API_VERSION=3
export OS_USERNAME=accounting
export OS_PASSWORD=<the user password>
export OS_AUTH_TYPE=password
export OS_CACERT=/etc/pki/tls/certs/ca-bundle.crt

Create the file /var/lib/bdii/gip/provider/cloud-info-provider that calls the provider with the correct options for your site, for example: 

cat<<EOF>/var/lib/bdii/gip/provider/cloud-info-provider
#!/bin/sh
 
. /etc/cloud-info-provider/openstack.rc
 
for P in $(openstack project list -c Name -f value); do
    cloud-info-provider-service --yaml /etc/cloud-info-provider/openstack.yaml \
                                --os-tenant-name $P \
                                --middleware openstack
done
EOF

Run manually the cloud-info-provider script and check that the output return the complete LDIF. To do so, execute: 

chmod +x /var/lib/bdii/gip/provider/cloud-info-provider
/var/lib/bdii/gip/provider/cloud-info-provider
/sbin/chkconfig bdii on

Now you can start the bdii service: 

systemctl start bdii

Use the command below to see if the information is being published: 

ldapsearch -x -h localhost -p 2170 -b o=glue

Do not forget to open port 2170: 

firewall-cmd --add-port=2170/tcp
firewall-cmd --permanent --add-port=2170/tcp
systemctl restart firewalld

Information on how to set up the site-BDII in egi-cloud-sbdii.pd.infn.it is available here

Add your cloud-info-provider to your site-BDII egi-cloud-sbdii.pd.infn.it by adding new lines in the site.def like this: 

BDII_REGIONS="CLOUD BDII"
BDII_CLOUD_URL="ldap://egi-cloud-ha.pn.pd.infn.it:2170/GLUE2GroupID=cloud,o=glue"
BDII_BDII_URL="ldap://egi-cloud-sbdii.pd.infn.it:2170/mds-vo-name=resource,o=grid"

Use the same APEL/SSM of grid site

Cloud usage records are sent to APEL through the ssmsend program installed in cert-37.pd.infn.it: 

[root@cert-37 ~]# cat /etc/cron.d/ssm-cloud 
# send buffered usage records to APEL
30 */24 * * * root /usr/bin/ssmsend -c /etc/apel/sender-cloud.cfg

It is therefore neede to install and configure NFS on egi-cloud-ha: 

[root@egi-cloud-ha ~]# yum -y install nfs-utils
[root@egi-cloud-ha ~]# mkdir -p /var/spool/apel/outgoing/openstack
[root@egi-cloud-ha ~]# cat<<EOF>>/etc/exports 
/var/spool/apel/outgoing/openstack cert-37.pd.infn.it(rw,sync)
EOF
[root@egi-cloud-ha ~]# systemctl start nfs-server

In case of APEL nagios probe failure, check if /var/spool/apel/outgoing/openstack is properly mounted by cert-37

To check if accounting records are properly received by APEL server look at this site

Install the accounting system (cASO)

(see cASO installation guide )

On egi-cloud create accounting user and role, and set the proper policies: 

openstack user create --domain default --password <ACCOUNTIN_PASSWORD> accounting
openstack role create accounting
for i in VO:fedcloud.egi.eu VO:enmr.eu VO:ops; do openstack role add --project $i --user accounting accounting; done
cat<<EOF>>/etc/keystone/policy.json
"accounting_role": "role:accounting"
"identity:list_users": "rule:admin_required or rule:accounting_role"
EOF

Install cASO on egi-cloud-ha (with CMD-OS repo already installed): 

yum -y install caso

Edit the /etc/caso/caso.conf file 

openstack-config --set /etc/caso/caso.conf DEFAULT site_name INFN-PADOVA-STACK

Install Cloudkeeper and Cloudkeeper-OS

On egi-cloud.pd.infn.it create a cloudkeeper user in keystone: 

openstack user create --domain default --password CLOUDKEEPER_PASS cloudkeeper

and, for each project, add the cloudkeeper user with the user role 

for i in VO:ops VO:fedcloud.egi.eu VO:enmr.eu; do openstack role add --project $i --user cloudkeeper user; done

Install Cloudkeeper and Cloudkeeper-OS on egi-cloud-ha (with CMD-OS repo already installed): 

yum -y install cloudkeeper cloudkeeper-os

Edit /etc/cloudkeeper/cloudkeeper.yml and add the list of VO image lists and the IP address where needed: 

  - https://PERSONAL_ACCESS_TOKEN:x-oauth-basic@vmcaster.appdb.egi.eu/store/vo/fedcloud.egi.eu/image.list
  - https://PERSONAL_ACCESS_TOKEN:x-oauth-basic@vmcaster.appdb.egi.eu/store/vo/ops/image.list
  - https://PERSONAL_ACCESS_TOKEN:x-oauth-basic@vmcaster.appdb.egi.eu/store/vo/enmr.eu/image.list

Install and configure squid on cloud-01 and cloud-02 for use from VMs (see https://cvmfs.readthedocs.io/en/stable/cpt-squid.html): 

yum install -y squid
sed -i "s|/var/spool/squid|/export/data/spool/squid|g" /etc/squid/squid.conf
cat<<EOF>>/etc/squid/squid.conf
minimum_expiry_time 0
 
max_filedesc 8192
maximum_object_size 1024 MB
 
cache_mem 128 MB
maximum_object_size_in_memory 128 KB
# 50 GB disk cache
cache_dir ufs /export/data/spool/squid 50000 16 256

rm -rf /var/spool/squid
mkdir -p /export/data/spool/squid
chown -R squid.squid /export/data/spool/squid
squid -k parse
squid -z
ulimit -n 8192
systemctl start squid
firewall-cmd --permanent --add-port 3128/tcp
systemctl restart firewalld

Use CVMFS_HTTP_PROXY="http://cloud-01.pn.pd.infn.it:3128|http://cloud-02.pn.pd.infn.it:3128" on the CVMFS clients.

Actually, better to use already existing squids: CVMFS_HTTP_PROXY="http://squid-01.pd.infn.it:3128|http://squid-02.pd.infn.it:3128"

$ echo encryption_method=1 >> /etc/nagios/send_nsca.cfg
$ usermod -a -G libvirt nagios
$ sed -i 's|#password=|password=NSCA_PASSWORD|g' /etc/nagios/send_nsca.cfg

Security incindents and IP traceability

See here for the description of the full process On egi-cloud do install the CNRS tools, they allow to track the usage of floating IPs as in the example below: 

[root@egi-cloud ~]# os-ip-trace 90.147.77.229
+--------------------------------------+-----------+---------------------+---------------------+
|              device id               | user name |   associating date  | disassociating date |
+--------------------------------------+-----------+---------------------+---------------------+
| 3002b1f1-bca3-4e4f-b21e-8de12c0b926e |   admin   | 2016-11-30 14:01:38 | 2016-11-30 14:03:02 |
+--------------------------------------+-----------+---------------------+---------------------+

Save and archive important log files:

Install ulogd in the controller node 

yum install -y libnetfilter_log
yum localinstall -y http://repo.iotti.biz/CentOS/7/x86_64/ulogd-2.0.5-2.el7.lux.x86_64.rpm
yum localinstall -y http://repo.iotti.biz/CentOS/7/x86_64/libnetfilter_acct-1.0.2-3.el7.lux.1.x86_64.rpm

and configure /etc/ulogd.conf by replacing properly accept_src_filter variable (accept_src_filter=10.0.0.0/16) starting from the one in cld-ctrl-01:/etc/ulogd.conf. Then copy cld-ctrl-01:/root/ulogd/start-ulogd to egi-cloud:/root/ulogd/start-ulogd, replace the qrouter ID and execute /root/ulogd/start-ulogd. Then add to /etc/rc.d/rc.local the line /root/ulogd/start-ulogd &, and make rc.local executable. Start the service 

systemctl enable ulogd
systemctl start ulogd

Finally, be sure that /etc/rsyslog.conf file has the lines "local6.* /var/log/ulogd.log" and "*.info;mail.none;authpriv.none;cron.none;local6.none /var/log/messages", and restart rsyslog service.
