CentOS6.2下一步一步源代碼安裝OpenStack（九）Swift存儲節點安裝、配置及運行

軟件安裝

Swift依賴以下軟件python-setuptools,xinetd, xfsprogs, pip, greenlet, eventlet, Paste, PasteDeploy, simplejson, WebOb,xattr, netifaces。 python-setuptools, xinetd和xfsprogs可通過在線或我原來提供的光盤安裝方法安裝，後面幾個除netifaces外在我原來提供的軟件包中都有。

yum install python-setuptools xinetd xfsprogs
tar zxpf pip-1.1.tar.gz && cd pip-1.1 && python setup.py install
cd ../pipdowns
pip install greenlet-0.3.4.zip eventlet-0.9.16.tar.gz Paste* simplejson-2.5.0.tar.gz WebOb-1.0.8.zip xattr-0.6.4.tar.gz
pip install netifaces
cd .. && tar zxpf swift-1.4.8.tar.gz && cd swift-1.4.8 && python setup.py install

創建swift使用的磁盤

我這裏以我的/dev/sdb爲例

fdisk /dev/sdb (依次輸入n<Enter>p<Enter>1<Enter><Enter><Enter>w<Enter>)
mkfs.xfs -i size=1024 /dev/sdb1
echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab
mkdir -p /srv/node/sdb1
mount /srv/node/sdb1
useradd –Mr swift
chown -R swift:swift /srv/node

設置ntp

Ntp的設置同CentOS6.2下一步一步源代碼安裝OpenStack（七）安裝配置計算節點計算節點的ntp設置一樣。

設置rsync

創建文件/etc/rsyncd.conf

uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
#address = <STORAGE_LOCAL_NET_IP> 

[account]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/account.lock 

[container]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/container.lock 

[object]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/object.lock

修改/etc/xinetd.d/rsync

sed -i 's/yes/no/' /etc/xinetd.d/rsync
sed -i 's/IPv6/IPv4/' /etc/xinetd.d/rsync

啓動xinetd

service xinetd start

創建配置文件

mkdir /etc/swift

創建文件 /etc/swift/account-server.conf:

[DEFAULT]
#bind_ip = <STORAGE_LOCAL_NET_IP>
workers = 2 

[pipeline:main]
pipeline = account-server 

[app:account-server]
use = egg:swift#account 

[account-replicator] 

[account-auditor] 

[account-reaper]
 

創建文件 /etc/swift/container-server.conf:

[DEFAULT]
#bind_ip = <STORAGE_LOCAL_NET_IP>
workers = 2 

[pipeline:main]
pipeline = container-server 

[app:container-server]
use = egg:swift#container 

[container-replicator] 

[container-updater] 

[container-auditor]
 

創建文件 /etc/swift/object-server.conf:

[DEFAULT]
#bind_ip = <STORAGE_LOCAL_NET_IP>
workers = 2 

[pipeline:main]
pipeline = object-server 

[app:object-server]
use = egg:swift#object 

[object-replicator] 

[object-updater] 

[object-auditor] 

[object-expirer]
 

將代理節點產生的account.ring.gz, container.ring.gz和 object.ring.gz及swift.conf拷到/etc/swift並更改文件用戶

chown –R swift:swift /etc/swift

以上配置文件中有一項bind_ip設置，目的是隻監聽內網ip的相應端口，但是這樣把配置文件拷到每個存儲節點時都要修改，我覺得可以把這項去掉，這樣所有存儲節點的配置就是一樣了，直接用就是，真需要考慮安全的話可以在iptables上只開放內網的ip及端口即可。

啓動存儲節點

swift-init object-serverstart
swift-init object-replicator start
swift-init object-updater start
swift-init object-auditor start
swift-init container-server start
swift-init container-replicator start
swift-init container-updater start
swift-init container-auditor start
swift-init account-server start
swift-init account-replicator start
swift-init account-auditor start
