OpenStack Dalmatian : Configure Swift (Storage Node)2024/10/15 |
|
Configure OpenStack Object Storage (Swift). This example is based on the environment like follows.

Configure Storage Node on this section. |
|
| [1] | On all Storage Nodes, Configure OpenStack Dalmatian repository first like [3] of here and Install Swift-Account, Swift-Container, Swift-Object and others on all Storage Node like follows. |
|
[root@snode01 ~]# dnf --enablerepo=centos-openstack-dalmatian,epel,crb -y install openstack-swift-account openstack-swift-container openstack-swift-object openstack-selinux xfsprogs rsync rsync-daemon openssh-clients
|
| [2] | Format free space of disk ([/dev/sdb1] on this example) with XFS and mount on [/srv/node/device] on all Storage Node like follows. |
|
[root@snode01 ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1 isize=512 agcount=4, agsize=5242816 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=1, sparse=1, rmapbt=0
= reflink=1 bigtime=1 inobtcount=1
data = bsize=4096 blocks=20971264, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0, ftype=1
log =internal log bsize=4096 blocks=10239, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
Discarding blocks...Done.
[root@snode01 ~]#
mkdir -p /srv/node/device [root@snode01 ~]# mount -o noatime,nodiratime /dev/sdb1 /srv/node/device [root@snode01 ~]# chown -R swift:swift /srv/node
[root@snode01 ~]#
blkid | grep sdb1 /dev/sdb1: UUID="09c9f4e6-dd4e-4399-a38d-2b70e2a02141" TYPE="xfs" PARTUUID="10c53ab5-01"
[root@snode01 ~]#
vi /etc/fstab # add to last line UUID="09c9f4e6-dd4e-4399-a38d-2b70e2a02141" /srv/node/device xfs defaults,noatime,nodiratime 0 0 |
| [3] | Copy Swift Ring files from the Swift Proxy Node to all Storage Nodes. |
|
[root@network ~]# scp /etc/swift/*.gz 10.0.0.71:/etc/swift/ 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@snode01 ~]# chown swift:swift /etc/swift/*.gz
[root@snode01 ~]#
vi /etc/swift/swift.conf # line 9, 10 : change to the same value which is set on Proxy Node [swift-hash] swift_hash_path_suffix = swift_shared_path swift_hash_path_prefix = swift_shared_path
[root@snode01 ~]#
vi /etc/swift/account-server.conf # line 2 : uncomment [DEFAULT] bind_ip = 0.0.0.0 bind_port = 6202
[root@snode01 ~]#
vi /etc/swift/container-server.conf # line 2 : uncomment [DEFAULT] bind_ip = 0.0.0.0 bind_port = 6201
[root@snode01 ~]#
vi /etc/swift/object-server.conf # line 2 : uncomment [DEFAULT] bind_ip = 0.0.0.0 bind_port = 6200
[root@snode01 ~]#
vi /etc/rsyncd.conf # add to last line pid file = /var/run/rsyncd.pid log file = /var/log/rsyncd.log uid = swift gid = swift address = 0.0.0.0 [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] | On Storage Node, if SELinux is enabled, change policy like follows. |
|
[root@snode01 ~]# setsebool -P domain_can_mmap_files on [root@snode01 ~]# semanage fcontext -a -t swift_data_t /srv/node/device [root@snode01 ~]# restorecon /srv/node/device
|
| [6] | On Storage Node, if Firewalld is running, allow service ports. |
|
[root@snode01 ~]# firewall-cmd --add-port={873/tcp,6200/tcp,6201/tcp,6202/tcp} success [root@snode01 ~]# firewall-cmd --runtime-to-permanent success |
| [7] | Start Swift services. |
|
[root@snode01 ~]# systemctl enable --now rsyncd \ openstack-swift-account-auditor \ openstack-swift-account-replicator \ openstack-swift-account \ openstack-swift-container-auditor \ openstack-swift-container-replicator \ openstack-swift-container-updater \ openstack-swift-container \ openstack-swift-object-auditor \ openstack-swift-object-replicator \ openstack-swift-object-updater \ openstack-swift-object |
