logrotate not working

When default log rotate is not working we need to check its configuration using command

/usr/sbin/logrotate -f /etc/logrotate.conf

and try running a selected configuration using

logrotate -fd /etc/logrotate.d/test

where test is the configuration file name.

Openstack Icehouse install Part -7 Cinder Service Block storage

Install Cinder- Block Storage Service

On Controller Node
Install the appropriate packages

yum install openstack-cinder -y

Configure Block Storage to use your database

openstack-config --set /etc/cinder/cinder.conf database connection mysql://cinder:cinder4admin@controller/cinder

Creating Database
On Mysql Server

mysql -u root -p

CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.30' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.31' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.35' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.36' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.32' IDENTIFIED BY 'cinder4admin';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'10.1.15.42' IDENTIFIED BY 'cinder4admin';
exit;

Create the database tables

su -s /bin/sh -c "cinder-manage db sync" cinder

Create a cinder user.

keystone user-create --name=cinder --pass=cinder4admin --email=cinder@example.com
keystone user-role-add --user=cinder --tenant=service --role=admin

Edit the /etc/cinder/cinder.conf configuration file:

openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder4admin

Configure Block Storage to use the Qpid message broker:

openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname 10.1.15.40

Register the Block Storage service with the Identity service so that other OpenStack services can locate it:

keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
keystone endpoint-create --service-id=$(keystone service-list | awk '/ volume / {print $2}') --publicurl=http://controller:8776/v1/%\(tenant_id\)s --internalurl=http://controller:8776/v1/%\(tenant_id\)s --adminurl=http://controller:8776/v1/%\(tenant_id\)s

Register a service and endpoint for version 2 of the Block Storage service API:

keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storage v2"
keystone endpoint-create --service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') --publicurl=http://controller:8776/v2/%\(tenant_id\)s --internalurl=http://controller:8776/v2/%\(tenant_id\)s --adminurl=http://controller:8776/v2/%\(tenant_id\)s

Start and configure the Block Storage services to start when the system boots:

service openstack-cinder-api start
service openstack-cinder-scheduler start
chkconfig openstack-cinder-api on
chkconfig openstack-cinder-scheduler on

On Cinder Service Node.

Setting Up NFS Share .

Installing NFS packages
yum install nfs-utils nfs-utils-lib

Make and configure partition
mkfs.ext4 /dev/mapper/vg_cloud2-LogVol03
mkdir /home/cinder_nfs
mount /dev/mapper/vg_cloud2-LogVol03 /home/cinder_nfs/
Add entries in Fstab
/dev/mapper/vg_cloud2-LogVol02 /home/cinder_nfs ext4 rw 0 0

Add Share to NFS
vi /etc/exports
/home/cinder_nfs *(rw,sync,no_root_squash,no_subtree_check)
exportfs -a
showmount -e 192.168.11.42

service nfs start
service nfs restart
service iptables stop
chkconfig iptables off
Install the Cinder Software
yum install openstack-cinder scsi-target-utils

Configure the Service

Copy the /etc/cinder/cinder.conf configuration file from the controller, or perform the following steps to set the keystone credentials:
openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder4admin
openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname 10.1.15.40

openstack-config --set /etc/cinder/cinder.conf database connection mysql://cinder:cinder4admin@controller/cinder
openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host controller

[root@compute2 ~]# cat /etc/cinder/nfsshares
192.168.11.42:/home/cinder_nfs
[root@compute2 ~]#

openstack-config --set /etc/cinder/cinder.conf DEFAULT nfs_shares_config /etc/cinder/nfsshares
openstack-config --set /etc/cinder/cinder.conf DEFAULT volume_driver cinder.volume.drivers.nfs.NfsDriver
service openstack-cinder-volume start
chkconfig openstack-cinder-volume on
