16 Oracle Linux Manager XML/RPC API
警告:
このドキュメントで説明するソフトウェアは、Extended Supportでの期間限定でサポートされます。 Oracle Linux 7は現在拡張サポート中です。 詳細は、Oracle Linux拡張サポートおよびOracleオープン・ソース・サポート・ポリシーを参照してください。
OS管理ハブを使用してオペレーティング・システム・インフラストラクチャを管理することを検討してください。 詳細は、「OS管理ハブ」を参照してください。
上級ユーザーは、Oracle Linux Manager XML/RPC APIを使用して、タスクを実行または自動化するwebインタフェースおよびスクリプトを作成できます。 APIの詳細は、Oracle Linux Managerサーバーのhttps://olmsvr_FQDN/rpc/apiを参照してください。
たとえば、次のget-channel-summaries Pythonスクリプトは、APIを使用して、チャネルのリスト、各チャネルのパッケージ数および各チャネルにサブスクライブされているシステム数を取得します:
#!/usr/bin/python
#
# get-channel-summaries [--server URL <url>] [--username <user>] [--password <passwd>]
import getopt, struct, sys, xmlrpclib
from array import *
# Insert default values for Oracle Linux Manager server API URL,
# Oracle Linux Manager admin user name, and Oracle Linux Manager admin password
url = "https://olmsvr.mydom.com/rpc/api"
username = "swadmin"
password = "swadmin"
usage1 = "Usage: get-channel-summaries [--serverUrl <url>] \\\n"
usage2 = " [--username <user>] [--password <passwd>]"
try:
opts,args = getopt.getopt(sys.argv[1:],"s:u:p:",["serverUrl=","username=","password="])
except getopt.GetoptError as err:
print(usage1+usage2)
sys.exit(1)
for o,a in opts:
if o in ("-s", "--serverUrl"):
url = a
elif o in ("-u", "--username"):
username = a
elif o in ("-p", "--password"):
password = a
else:
assert False, "Unknown option"
# Connect to Oracle Linux Manager
client = xmlrpclib.Server(url,verbose=0)
session = client.auth.login(username,password)
# Get channel list
channels = client.channel.listAllChannels(session)
# Build channel arrays indexed by channel ID
channel_label = {}
channel_packages = {}
channel_systems = {}
for channel in channels:
channel_label[channel['id']] = channel['label']
channel_packages[channel['id']] = channel['packages']
channel_systems[channel['id']] = channel['systems']
# Print output header
fmt1 = '{0:<40s}{1:<10s}{2:<10s}'
print fmt1.format('Channel label','Packages','Systems')
print fmt1.format('-------------','--------','-------')
# Print channel label, package count, and system count -- sorted by label
fmt2 = '{0:<40s}{1:<10d}{2:<10d}'
for key,value in sorted(channel_label.iteritems(),key=lambda(k,v): (v,k)):
id = int(key)
print fmt2.format(value,channel_packages[id],channel_systems[id])
# Disconnect from Oracle Linux Manager
client.auth.logout(session)次に、このスクリプトを実行した場合の出力例を示します:
Channel label Packages Systems ------------- -------- ------- base-channel 0 0 epel6-channel-label 68 0 epel6-channel1-label 3 0 epel6-channel2-label 1 0 ol5-i386-channel-label 44 0 ol5-i386-test-label 34 0 ol5-x64-channel-label 44 0 ol6-i386-channel-label 45 0 ol6-x64-channel-label 45 1 ol7-channel-label 45 1 oraclelinux6-x86_64 0 0 oraclelinux6-x86_64-addons 0 0 oraclelinux6-x86_64-spacewalk22-client 0 0 oraclelinux6-x86_64-spacewalk22-server 0 0 oraclelinux6-x86_64-spacewalk24-client 0 0 oraclelinux6-x86_64-spacewalk24-server 0 0 oraclelinux6-x86_64-spacewalk26-client 0 0 oraclelinux6-x86_64-spacewalk26-server 0 0 oraclelinux6-x86_64-spacewalk27-server 0 0 uln-channel-label 173 0
次の例は、リポジトリを同期するためのスケジュールを表示するget-reposync-listスクリプトを示しています。
#!/usr/bin/python
#
# get-reposync-list [--serverUrl <url>] [--username <user>] [--password <passwd>]
import getopt, struct, sys, xmlrpclib
from array import *
# Insert default values for Oracle Linux Manager server API URL,
# Oracle Linux Manager admin user name, and Oracle Linux Manager admin password
url = "https://olmsvr.mydom.com/rpc/api"
username = "swadmin"
password = "swadmin"
usage1 = "Usage: get-reposync-list [--serverUrl <url>] \\\n"
usage2 = " [--username <user>] [--password <passwd>]"
try:
opts,args = getopt.getopt(sys.argv[1:],"s:u:p:",["serverUrl=","username=","password="])
except getopt.GetoptError as err:
print(usage1+usage2)
sys.exit(1)
for o,a in opts:
if o in ("-s", "--serverUrl"):
url = a
elif o in ("-u", "--username"):
username = a
elif o in ("-p", "--password"):
password = a
else:
assert False, "Unknown option"
# Connect to Oracle Linux Manager
client = xmlrpclib.Server(url,verbose=0)
session = client.auth.login(username,password)
# Get channel list
channels = client.channel.listAllChannels(session)
# Build channel name array indexed by channel ID
channel_label = {}
channel_schedule = {}
for channel in channels:
id = int(channel['id'])
channel_label[id] = channel['label']
channel_schedule[id] = ''
# Get repository synchronization list
schedules = client.taskomatic.org.listActiveSchedulesByBunch(session,'repo-sync-bunch')
# Construct schedule array indexed by channel ID
for schedule in schedules:
channel_schedule[int(schedule['data_map']['channel_id'])] = schedule['cron_expr']
# Print output header
fmt = '{0:<40s}{1:<40s}'
print fmt.format('Channel label','Schedule')
print fmt.format('-------------','--------')
# Print channel labels and repository synchronization schedule (if defined)
for key,value in sorted(channel_label.iteritems(),key=lambda(k,v):(v,k)):
id = int(key)
sched = channel_schedule[id]
if (len(sched) > 0):
print fmt.format(value,sched)
else:
print fmt.format(value,"Sync not scheduled")
# Disconnect from Oracle Linux Manager
client.auth.logout(session)次の例は、このコマンドの出力結果を示しています:
