增量导入导出要基于快照

导出的过程当中害怕镜像被修改所以打快照。快照的数据是不会变化的

镜像级别的双向同步

镜像主到备，备到主。一对一就算是池模式的双向同步，镜像也具有主备关系

双向同步，池模式

[root@clienta ~]# ceph osd pool create rbd

pool 'rbd' created

[root@clienta ~]# rbd pool init rbd

[root@clienta ~]# ceph orch apply rbd-mirror --placement=serverc.lab.example.com

Scheduled rbd-mirror update...

[root@clienta ~]# 

[root@serverf ~]# ceph osd pool create rbd

pool 'rbd' created

[root@serverf ~]# rbd pool init rbd

[root@serverf ~]# ceph orch apply rbd-mirror --placement=serverf.lab.example.com

Scheduled rbd-mirror update...

[root@serverf ~]#

一个集群任意一个节点安装rbd-mirror就行了

[root@serverf ~]# rbd mirror pool enable rbd pool

[root@serverf ~]# 

[root@clienta ~]# rbd mirror pool enable rbd pool

[root@clienta ~]#

两边开启池模式

（这个import导入，做一边就可以，也就是可以省一个scp步骤。还是建议在serverf这里做import）

在备集群创建镜像，主集群同步

镜像的1对1同步，被同步为false

报错

[root@clienta ~]# rbd mirror pool status

这个错误会让池子变为单向同步，很致命。会报超时。

过程整理

主集群操作

ceph osd pool create rbd

rbd pool init rbd

rbd mirror pool enable rbd pool # 开启池模式同步

ceph orch apply rbd-mirror --placement=serverf.lab.example.com #安装rbd mirror

rbd mirror pool peer bootstrap create --site-name prod rbd > /root/prod

rsycn prod root@serverf:~

备集群操作

ceph osd pool create rbd

rbd pool init rbd

rbd mirror pool enable rbd pool

ceph orch apply rbd-mirror --placement=serverf.lab.example.com #安装rbd mirror

rbd mirror pool peer bootstrap import --site-name bup rbd /root/prod

rbd ls

测试：

在prod和bup集群上各自创建镜像，可以互相同步

rbd create image1 --size 1024 --pool rbd --image-feature exclusive-lock,journaling  #创建镜像，开启排他锁和日志功能

主备镜像切换

rbd mirror image demote test1 降级（备）

rbd mirror image promote test1 升级（主）

先降级

以前的osd都有xfs文件系统（filestore）

现在bluestore osd都以逻辑卷的形式作为存储。在裸盘上，未被格式化

对象存储

mon 拥有用户数据，存储池信息，和osd信息。mon与mon之间也会数据同步

mgr 主备部署，可以实现dashboard web服务，可与监控工具对接（收集osd信息，数据统计）

rgw 可以提供web服务，并提供s3 swift接口

rgw对ceph来说为客户端，只要是客户端就要做认证

官方部署文档位置

https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/5/html/object_gateway_guide/deployment#deploying-the-ceph-object-gateway-using-the-command-line-interface_rgw

删除原有rgw

[student@workstation ~]$ lab start  object-radosgw

部署rgw

serverc serverd

两个都 8080 端口（主备）

[root@clienta ~]#

设置配额，但未启用

[root@clienta ~]# radosgw-admin  quota enable --quota-scope=user --uid=user1

[root@clienta ~]# radosgw-admin  quota enable --quota-scope=bucket --uid=user1

启用用户和bucket配额

[root@clienta ~]# radosgw-admin quota set --quota-scope=bucket --uid=user1  --max-objects=1024 --max-size=200M

设置bucket 虽然你用户能有1G的对象大小，但你每个bucket只能存200M(你不能把1G存在一个bucket里)

用户访问rgw

clienta为ceph集群的客户端（集群管理范围内）

安装

[root@clienta ~]# yum -y install awscli

aws configure --profile=ceph 输入用户ak和sk

[root@clienta ~]# aws --profile=ceph configure

AWS Access Key ID [None]: 123

AWS Secret Access Key [None]: 456

Default region name [None]:

Default output format [None]:

[root@clienta ~]# 

[root@clienta ~]# cd .aws/

[root@clienta .aws]# ls

config  credentials

[root@clienta .aws]# cat config

[profile ceph]

[root@clienta .aws]# cat credentials

[ceph]

aws_access_key_id = 123

aws_secret_access_key = 456

[root@clienta .aws]#

--profile 也可以不加，指定就是ceph，不指定就为ceph

[root@clienta .aws]# aws s3 ls --profile=ceph --endpoint=http://serverc:8080

[root@clienta .aws]#

[root@clienta .aws]# aws s3  --profile=ceph --endpoint=http://serverc:8080 mb s3://bucket1

make_bucket: bucket1

[root@clienta .aws]# aws s3 ls --profile=ceph --endpoint=http://serverc:8080

2022-08-16 05:58:31 bucket1

[root@clienta .aws]#

上传对象到bucket

[root@clienta .aws]# aws s3 cp /etc/ceph/ceph.conf  s3://bucket1/ceph2  --profile=ceph --endpoint=http://serverc:8080

upload: ../../etc/ceph/ceph.conf to s3://bucket1/ceph2

[root@clienta .aws]# aws s3 ls s3://bucket1  --profile=ceph --endpoint=http://serverc:8080

2022-08-16 06:00:02        177 ceph2

上传一个公共文件（不需要验证秘钥）

[root@clienta .aws]# aws --profile=ceph --endpoint=http://serverc:8080 --acl=public-read-write s3 cp /etc/passwd  s3://bucket1/

upload: ../../etc/passwd to s3://bucket1/passwd

[root@clienta .aws]#

第一种访问方式

[root@foundation0 ~]# wget http://serverc:8080/bucket1/passwd

第二种

[root@foundation0 tmp]# wget http://bucket1.serverc:8080/passwd

这种方式得做域名解析

*.serverc   172.25.250.12   泛域名解析

红帽文档有详情

还得开启bucket功能

[student@workstation ~]$ ping aca.serverc

PING aca.serverc (172.25.250.12) 56(84) bytes of data.

64 bytes from serverc.lab.example.com (172.25.250.12): icmp_seq=1 ttl=64 time=6.67 ms

管理员权限命令

[root@clienta .aws]# radosgw-admin bucket rm --bucket=bucket1

2022-08-16T06:17:18.744-0400 7f9f237a8380 -1 ERROR: could not remove non-empty bucket bucket1
