about rgw region sync

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

could i build one region using two clusters£¬ each cluster has one zone¡£ so that I sync metadata and data from one cluster to another cluster¡£
I build two ceph clusters.
for the first cluster, I do the follow steps
1.create pools
sudo ceph osd pool create .us-east.rgw.root 64  64
sudo ceph osd pool create .us-east.rgw.control 64 64
sudo ceph osd pool create .us-east.rgw.gc 64 64
sudo ceph osd pool create .us-east.rgw.buckets 64 64
sudo ceph osd pool create .us-east.rgw.buckets.index 64 64
sudo ceph osd pool create .us-east.rgw.buckets.extra 64 64
sudo ceph osd pool create .us-east.log 64 64
sudo ceph osd pool create .us-east.intent-log 64 64
sudo ceph osd pool create .us-east.usage 64 64
sudo ceph osd pool create .us-east.users 64 64
sudo ceph osd pool create .us-east.users.email 64 64
sudo ceph osd pool create .us-east.users.swift 64 64
sudo ceph osd pool create .us-east.users.uid 64 64
 
2.create a keyring
sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
sudo chmod +r /etc/ceph/ceph.client.radosgw.keyring
sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-east-1 --gen-key
sudo ceph-authtool -n client.radosgw.us-east-1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-east-1 -i /etc/ceph/ceph.client.radosgw.keyring

3.create a region
sudo radosgw-admin region set --infile us.json --name client.radosgw.us-east-1
sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-east-1
sudo radosgw-admin regionmap update --name client.radosgw.us-east-1
   the content of us.json:
cat us.json
{ "name": "us",
  "api_name": "us",
  "is_master": "true",
  "endpoints": [
        "http:\/\/WH-CEPH-TEST01.MATRIX.CTRIPCORP.COM:80\/", "http:\/\/WH-CEPH-TEST02.MATRIX.CTRIPCORP.COM:80\/"],
  "master_zone": "us-east",
  "zones": [
        { "name": "us-east",
          "endpoints": [
                "http:\/\/WH-CEPH-TEST01.MATRIX.CTRIPCORP.COM:80\/"],
          "log_meta": "true",
          "log_data": "true"},
        { "name": "us-west",
          "endpoints": [
                "http:\/\/WH-CEPH-TEST02.MATRIX.CTRIPCORP.COM:80\/"],
          "log_meta": "true",
          "log_data": "true"}],
  "placement_targets": [
   {
     "name": "default-placement",
     "tags": []
   }
  ],
  "default_placement": "default-placement"}
4.create zones
sudo radosgw-admin zone set --rgw-zone=us-east --infile us-east-secert.json --name client.radosgw.us-east-1
sudo radosgw-admin regionmap update --name client.radosgw.us-east-1
cat us-east-secert.json
{ "domain_root": ".us-east.domain.rgw",
  "control_pool": ".us-east.rgw.control",
  "gc_pool": ".us-east.rgw.gc",
  "log_pool": ".us-east.log",
  "intent_log_pool": ".us-east.intent-log",

  "user_swift_pool": ".us-east.users.swift",
  "user_uid_pool": ".us-east.users.uid",
  "system_key": { "access_key": "XNK0ST8WXTMWZGN29NF9", "secret_key": "7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5"},
  "placement_pools": [
    { "key": "default-placement",
      "val": { "index_pool": ".us-east.rgw.buckets.index",
               "data_pool": ".us-east.rgw.buckets"}
    }
  ]
}

#5 Create Zone Users system user
sudo radosgw-admin user create --uid="us-east" --display-name="Region-US Zone-East" --name client.radosgw.us-east-1 --access_key="XNK0ST8WXTMWZGN29NF9" --secret="7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5" --system

#6 creat zone users not system user
sudo radosgw-admin user create --uid="us-test-east" --display-name="Region-US Zone-East-test" --name client.radosgw.us-east-1 --access_key="DDK0ST8WXTMWZGN29NF9" --secret="DDJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5"
#7 subuser create
sudo radosgw-admin subuser create --uid="us-test-east"  --subuser="us-test-east:swift" --access=full --name client.radosgw.us-east-1 --key-type swift --secret="ffJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5"
sudo /etc/init.d/ceph -a restart
sudo /etc/init.d/httpd re
sudo /etc/init.d/ceph-radosgw restart
 
for the  second cluster, I do the follow steps
1.create pools
sudo ceph osd pool create .us-west.rgw.root 64  64
sudo ceph osd pool create .us-west.rgw.control 64 64
sudo ceph osd pool create .us-west.rgw.gc 64 64

sudo ceph osd pool create .us-west.users.swift 64 64
sudo ceph osd pool create .us-west.users.uid 64 64
2.create a keyring
sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
sudo chmod +r /etc/ceph/ceph.client.radosgw.keyring
sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-west-1 --gen-key
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth del client.radosgw.us-west-1
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-west-1 -i /etc/ceph/ceph.client.radosgw.keyring

3.create a region
sudo radosgw-admin region set --infile us.json --name client.radosgw.us-west-1
sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-west-1
sudo radosgw-admin regionmap update --name client.radosgw.us-west-1
cat us.json
the content of us.json:
{ "name": "us",
  "api_name": "us",
  "is_master": "true",
  "endpoints": [
        "http:\/\/WH-CEPH-TEST01.MATRIX.CTRIPCORP.COM:80\/", "http:\/\/WH-CEPH-TEST02.MATRIX.CTRIPCORP.COM:80\/"],
  "master_zone": "us-east",
  "zones": [
        { "name": "us-east",
          "endpoints": [
                "http:\/\/WH-CEPH-TEST01.MATRIX.CTRIPCORP.COM:80\/"],
          "log_meta": "true",
          "log_data": "true"},
        { "name": "us-west",

  "placement_targets": [
   {
     "name": "default-placement",
     "tags": []
   }
  ],
  "default_placement": "default-placement"}

4.create zones
sudo radosgw-admin zone set --rgw-zone=us-west --infile us-west-secert.json --name client.radosgw.us-west-1
sudo radosgw-admin regionmap update --name client.radosgw.us-west-1
the content of us-west-secert.json is:
cat us-west-secert.json
{ "domain_root": ".us-east.domain.rgw",
  "control_pool": ".us-east.rgw.control",
  "gc_pool": ".us-east.rgw.gc",

      "val": { "index_pool": ".us-east.rgw.buckets.index",
               "data_pool": ".us-east.rgw.buckets"}
    }
  ]
}
5.Create Zone Users system user
sudo radosgw-admin user create --uid="us-east" --display-name="Region-US Zone-East" --name client.radosgw.us-west-1 --access_key="XNK0ST8WXTMWZGN29NF9" --secret="7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5" --system
sudo radosgw-admin user create --uid="us-west" --display-name="Region-US Zone-West" --name client.radosgw.us-west-1 --access_key="AAK0ST8WXTMWZGN29NF9" --secret="AAJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5" --system
6.reboot
sudo /etc/init.d/ceph -a restart
sudo /etc/init.d/httpd restart
sudo /etc/init.d/ceph-radosgw restart
after all of above, on the first cluster, i do the follow steps
1.source self.env
the content of self.env is :
cat self.env
export ST_AUTH="http://10.18.5.49/auth/1.0"
export ST_KEY=ffJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
export ST_USER=us-test-east:swift
2.swift list
3.swift  upload test  self.env
4.swift list test
self.env
5.sudo radosgw-agent -c ./ceph-data-sync.conf
the content of ceph-data-sync.conf is£º
cat ceph-data-sync.conf
src_access_key: XNK0ST8WXTMWZGN29NF9
src_secret_key: 7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5

dest_access_key: XNK0ST8WXTMWZGN29NF9
dest_secret_key: 7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
log_file: /var/log/radosgw/radosgw-sync-us-east-west.log
there is some error as bellow£º
sudo radosgw-agent -c ./ceph-data-sync.conf

on the second cluster £¬i do the follow steps£º
1.source self.env
the content of self.env is :
cat self.env
export ST_AUTH="http://10.18.5.51/auth/1.0"
export ST_KEY=ffJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
export ST_USER=us-test-east:swift
2.swift list

3.radosgw-admin --name client.radosgw.us-west-1 user info --uid="us-test-east"
{ "user_id": "us-test-east",
  "display_name": "Region-US Zone-East-test",
  "email": "",
  "suspended": 0,
  "max_buckets": 1000,

  "user_quota": { "enabled": false,
      "max_size_kb": -1,
      "max_objects": -1},
  "temp_url_keys": []}
4.radosgw-admin --name client.radosgw.us-west-1 bucket list
[
    "test"]
5.radosgw-admin --name client.radosgw.us-west-1 --bucket=test  bucket list
[]

it seems like that metadata is replicated from the first cluster£¬ data is not¡£
I don't known why?
