OpenStack Juno : Configure Swift#3 ( Storage Node )2015/01/13 |
|
Configure OpenStack Object Storage (Swift).
This example shows to configure like the environment below.
|
+------------------+ | +-----------------+
| [ Control Node ] |10.0.0.30 | 10.0.0.50| [ Proxy Node ] |
| Keystone |-----------+-----------| |
+------------------+ | +-----------------+
|
+---------------------------+--------------------------+
| | |
|10.0.0.71 |10.0.0.72 |10.0.0.73
+-------+----------+ +--------+---------+ +--------+---------+
| [Storage Node#1] | | [Storage Node#2] | | [Storage Node#3] |
| |-------| |-------| |
+------------------+ +------------------+ +------------------+

Configure Storage Node on this section. It's OK to set the same settings mostly on all Storage Nodes,
but only IP address and Device number are different each other, though.
Furthermore, add Hard drives on each Storage Nodes and create a partition "/dev/sdb1" for this settings.
|
|
| [1] | Install Swift-Account, Swift-Container, Swift-Object and others on all Storage Node like follows. |
|
[root@node01 ~]# yum --enablerepo=openstack-juno,epel -y install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs rsync openssh-clients
|
| [2] | Format free space of disk (/dev/sdb1 on this example) with XFS and mount on srv/node on allStorage Node like follows. (the number "device*" is different on each Storage Nodes) |
|
[root@node01 ~]# mkfs.xfs -i size=1024 -s size=4096 /dev/sdb1
meta-data=/dev/sdb1 isize=1024 agcount=4, agsize=1310656 blks
= sectsz=4096 attr=2, projid32bit=1
= crc=0
data = bsize=4096 blocks=5242624, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=0
log =internal log bsize=4096 blocks=2560, version=2
= sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
[root@node01 ~]# mkdir -p /srv/node/device0 [root@node01 ~]# mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0 [root@node01 ~]# chown -R swift. /srv/node
[root@node01 ~]#
vi /etc/fstab # add at the last line /dev/sdb1 /srv/node/device0 xfs noatime,nodiratime,nobarrier 0 0 |
| [3] | Copy Swift Ring files from the Swift Proxy Node to all Storage Nodes. |
|
[root@proxy ~]# scp /etc/swift/*.gz 10.0.0.71:/etc/swift/ root@10.0.0.71's password: account.ring.gz 100% 3912 3.8KB/s 00:00 container.ring.gz 100% 3904 3.8KB/s 00:00 object.ring.gz 100% 3895 3.8KB/s 00:00 |
| [4] | Configure Swift and Rsync on all Storage Nodes. |
|
[root@node01 ~]# chown swift. /etc/swift/*.gz
[root@node01 ~]#
vi /etc/swift/swift.conf # set the value which is set on Proxy Node [swift-hash] swift_hash_path_suffix = swift_shared_path
[root@node01 ~]#
vi /etc/swift/account-server.conf # line 6: change to the own IP address, change the port bind_ip = 10.0.0.71 bind_port = 6002
[root@node01 ~]#
vi /etc/swift/container-server.conf # line 6: change to the own IP address, change the port bind_ip = 10.0.0.71 bind_port = 6001
[root@node01 ~]#
vi /etc/swift/object-server.conf # line 6: change to the own IP address, change the port bind_ip = 10.0.0.71 bind_port = 6000
[root@node01 ~]#
vi /etc/rsyncd.conf # add follows to the end pid file = /var/run/rsyncd.pid log file = /var/log/rsyncd.log uid = swift gid = swift address = 10.0.0.71 [account] path = /srv/node read only = false write only = no list = yes incoming chmod = 0644 outgoing chmod = 0644 max connections = 25 lock file = /var/lock/account.lock [container] path = /srv/node read only = false write only = no list = yes incoming chmod = 0644 outgoing chmod = 0644 max connections = 25 lock file = /var/lock/container.lock [object] path = /srv/node read only = false write only = no list = yes incoming chmod = 0644 outgoing chmod = 0644 max connections = 25 lock file = /var/lock/object.lock [swift_server] path = /etc/swift read only = true write only = no list = yes incoming chmod = 0644 outgoing chmod = 0644 max connections = 5 lock file = /var/lock/swift_server.lock |
| [5] | Start Swift services. |
|
[root@node01 ~]# systemctl start rsyncd [root@node01 ~]# systemctl enable rsyncd [root@node01 ~]# for ringtype in account container object; do
systemctl start openstack-swift-$ringtype
systemctl enable openstack-swift-$ringtype
for service in replicator updater auditor; do
if [ $ringtype != 'account' ] || [ $service != 'updater' ]; then
systemctl start openstack-swift-$ringtype-$service
systemctl enable openstack-swift-$ringtype-$service
