本节主要是使用nfs-kernel-server将cephfs或rbd映射为nfs。

1、安装nfs相关软件

apt-get install nfs-kernel-server
apt-get install nfs-common

2、在ceph-0001挂载好fuse和rbd

ceph-fuse /mnt/fuse
rbd map r1
mount -t ext4 /dev/rbd0 /mnt/rbd

3、配置exports文件

vi /etc/exports
/mnt/fuse         192.168.1.0/24(rw,sync,no_root_squash,no_subtree_check,fsid=0)
/mnt/rbd          192.168.1.0/24(rw,sync,no_root_squash,no_subtree_check)

4、更新配置

exportfs -a

systemctl restart nfs-kernel-server

showmount -e
Export list for ceph-0001:
/mnt/rbd  192.168.1.0/24
/mnt/fuse 192.168.1.0/24

5、到另一台机器进行挂载

mount -t nfs  ceph-0001:/mnt/fuse  /mnt/fuse --verbose
mount.nfs: timeout set for Fri Jun  5 19:06:27 2020
mount.nfs: trying text-based options 'vers=4.2,addr=192.168.1.101,clientaddr=192.168.1.103'
mount.nfs: mount(2): No such file or directory
mount.nfs: trying text-based options 'addr=192.168.1.101'
mount.nfs: prog 100003, trying vers=3, prot=6

本节主要是测试ceph的三种存储方式之一对象存储。

1、创建zone，并开启rgw

#创建realm
radosgw-admin realm create --rgw-realm=myrealm --default
#创建zonegroup
radosgw-admin zonegroup create --rgw-zonegroup=myzg --endpoints=http://ceph01:8080 --rgw-realm=myrealm --master --default
#创建zone
radosgw-admin zone create --rgw-zonegroup=myzg --rgw-zone=myzone --endpoints=http://ceph01:8080 --master --default
# 在ceph01启用rgw
ceph orch apply rgw myrealm myzone --placement="1 ceph01"

2、创建s3用户

radosgw-admin user create --uid=s3user --display-name=s3user  --system
{
  "user_id": "s3user",
  "display_name": "s3user",
  "email": "",
  "suspended": 0,
  "max_buckets": 1000,
  "auid": 0,
  "subusers": [],
  "keys": [
    {
      "user": "s3user",
      "access_key": "6IUA1DMFDTP5BG9ZMIR8",
      "secret_key": "zdoRS2yWL6EsNEBa4xuOSFMPn0lMvPJVMIYZJirP"
    }
  ],
  "swift_keys": [],
  "caps": [],
  "op_mask": "read, write, delete",
  "system": "true",
  "default_placement": "",
  "placement_tags": [],
  "bucket_quota": {
    "enabled": false,
    "check_on_raw": false,
    "max_size": -1,
    "max_size_kb": 0,
    "max_objects": -1
  },
  "user_quota": {
    "enabled": false,
    "check_on_raw": false,
    "max_size": -1,
    "max_size_kb": 0,
    "max_objects": -1
  },
  "temp_url_keys": [],
  "type": "rgw"
}

3、创建swift用户

sudo radosgw-admin subuser create --uid=s3user --subuser=s3user:swift --access=full
{
  "user_id": "s3user",
  "display_name": "s3user",
  "email": "",
  "suspended": 0,
  "max_buckets": 1000,
  "auid": 0,
  "subusers": [
    {
      "id": "s3user:swift",
      "permissions": "full-control"
    }
  ],
  "keys": [
    {
      "user": "s3user",
      "access_key": "6IUA1DMFDTP5BG9ZMIR8",
      "secret_key": "zdoRS2yWL6EsNEBa4xuOSFMPn0lMvPJVMIYZJirP"
    }
  ],
  "swift_keys": [
    {
      "user": "s3user:swift",
      "secret_key": "2wou5DxQ6WiBYyHf8qb3QIMX9BnhhBd5Njlj6LJX"
    }
  ],
  "caps": [],
  "op_mask": "read, write, delete",
  "system": "true",
  "default_placement": "",
  "placement_tags": [],
  "bucket_quota": {
    "enabled": false,
    "check_on_raw": false,
    "max_size": -1,
    "max_size_kb": 0,
    "max_objects": -1
  },
  "user_quota": {
    "enabled": false,
    "check_on_raw": false,
    "max_size": -1,
    "max_size_kb": 0,
    "max_objects": -1
  },
  "temp_url_keys": [],
  "type": "rgw"
}

4、通过s3接口新增一个bucket

sudo apt-get install python-boto

# 编辑s3test.py文件
vi s3test.py

import boto.s3.connection

access_key = '6IUA1DMFDTP5BG9ZMIR8'
secret_key = 'zdoRS2yWL6EsNEBa4xuOSFMPn0lMvPJVMIYZJirP'

conn = boto.connect_s3(
  aws_access_key_id=access_key,
  aws_secret_access_key=secret_key,
  host='ceph01', port=80,
  is_secure=False, calling_format=boto.s3.connection.OrdinaryCallingFormat(),
  )

bucket = conn.create_bucket('my-new-bucket')
for bucket in conn.get_all_buckets():
  print "{name} {created}".format(
    name=bucket.name,
    created=bucket.creation_date,
    )

#运行
python s3test.py
mybucket 2020-05-19T20:01:59.139Z

5、通过swift接口查询bucket

sudo apt-get install python-pip
sudo pip install --upgrade setuptools
sudo pip install --upgrade python-swiftclient

# 用swift工具查询bucket
swift -V 1 -A http://172.16.172.101:80/auth -U s3user:swift -K '2wou5DxQ6WiBYyHf8qb3QIMX9BnhhBd5Njlj6LJX' list
mybucket

5、通过s3cmd接口查询bucket

sudo apt-get install s3cmd

#生成配置
s3cmd --configure

#用s3cmd工具查询bucket
s3cmd ls
2020-05-19 20:01  s3://mybucket

本节主要是测试ceph的三种存储方式之一块存储。

1、创建存储池以及rbd

sudo ceph osd pool ls
sudo ceph osd pool create rbd

sudo rados df

sudo rbd ls
sudo rbd create --size 1024 rbd/r1

2、将映像映射到块设备

#直接映射会报一个错
#sudo rbd map r1
#rbd: sysfs write failed
#RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable r1 object-map fast-diff deep-flatten".
#In some cases useful info is found in syslog - try "dmesg | tail".
#rbd: map failed: (6) No such device or address

#修正错误，重新映射
sudo rbd feature disable r1 object-map fast-diff deep-flatten
sudo rbd map r1
/dev/rbd0

#查看映射情况
sudo rbd showmapped
id pool image snap device
0  rbd  r1    -    /dev/rbd0

3、初始化块设备

#fdis初始化设备
sudo fdisk -l /dev/rbd0

#格式化分区为ext4
sudo mkfs.ext4 -m0 /dev/rbd0

#挂载块设备
sudo mkdir -p /mnt/rbd/r1
sudo mount -t ext4 /dev/rbd0 /mnt/rbd/r1

4、进行一些基本操作

sudo ls /mnt/rbd/r1

sudo vi /mnt/rbd/r1/hi.txt

sudo cat /mnt/rbd/r1/hi.txt
hello rbd

CEPH环境搭建01

Posted on 2020/05/18 by neohope — No Comments ↓

1、初始环境

准备四个节点（每个节点的hosts和hostname要进行相应修改）：

ceph-0001	172.16.172.101
ceph-0002	172.16.172.102
ceph-0003	172.16.172.103
ceph-0004	172.16.172.104

每个节点都执行：

sudo apt-get update
sudo apt-get install docker.io

2、在主节点安装cephadm

#官方推荐的方法有问题
#sudo ./cephadm add-repo --release octopus
#The key(s) in the keyring /etc/apt/trusted.gpg.d/ceph.release.gpg are ignored as the file has an unsupported filetype.
#sudo rm /etc/apt/trusted.gpg.d/ceph.release.gpg

wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
echo deb http://download.ceph.com/debian-octopus/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
sudo apt-get update

curl --silent --remote-name --location https://github.com/ceph/ceph/raw/octopus/src/cephadm/cephadm
chmod 711 cephadm
sudo ./cephadm install

sudo cephadm install ceph-common

3、初始化

sudo mkdir -p /etc/ceph

INFO:cephadm:Please consider enabling telemetry to help improve Ceph:

ceph telemetry on

For more information see:

https://docs.ceph.com/docs/master/mgr/telemetry/

INFO:cephadm:Bootstrap complete.

4、此时可以通过最后给出的信息，登录管理页面了

5、修改配置文件

sudo vi /etc/ceph/ceph.conf

[global]
fsid = a4547d9d-f1a1-4753-b5cc-df0e043ebc65
mon_initial_members = ceph01
#原本生成的mon_host好像有些问题
#mon_host = [v2:ceph01:3300/0,v1:ceph:6789/0]
mon_host = 172.16.172.101
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
public_network = 172.16.172.0/24

6、查看ceph状态

sudo ceph status
cluster:
id:     7bffaaf6-9688-11ea-ac24-080027b4217f
health: HEALTH_WARN
Reduced data availability: 1 pg inactive

7、三个子节点做好准备

#在ceph01
#将ceph.pub拷贝到其他三个节点
scp /etc/ceph/ceph.pub  neohope@ceph02:~/authorized_keys

#在ceph02
#启用root
sudo passwd -u root
#设置好root的authorized_keys
mv authorized_keys  /root/.ssh/
cd /root/.ssh/
chown root:root authorized_keys
chmod 0600 authorized_keys
#允许root ssh登录
sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
sudo service ssh restart

#在ceph01
#获取私钥
sudo ceph config-key get mgr/cephadm/ssh_identity_key &amp;amp;amp;amp;amp;gt; ceph.pem
chmod 0600 ceph.pem
#测试root登录
ssh  -i ceph.pem root@ceph02

8、三个子节点加入网络

sudo ceph orch host add ceph02
Added host 'ceph02'

sudo ceph orch host add ceph03
Added host 'ceph03'

sudo ceph orch host add ceph04
Added host 'ceph04'

sudo ceph orch host ls
HOST    ADDR    LABELS  STATUS
ceph01  ceph01
ceph02  ceph02
ceph03  ceph03
ceph04  ceph04

9、设置mon

ceph orch apply mon 4
ceph orch apply mon ceph01,ceph02,ceph03,ceph04
sudo ceph status

ISTIO环境搭建02

Posted on 2020/05/13 by neohope — No Comments ↓

换了3个云厂商，才把最后的例子跑完。。。

1、下载示例源码

git clone https://github.com/istio/istio.git
Cloning into 'istio'...

2、生成镜像

cd istio/samples/helloworld/src
./build_service.sh
Sending build context to Docker daemon  7.168kB
Step 1/8 : FROM python:2-onbuild
2-onbuild: Pulling from library/python
......

sudo docker images
REPOSITORY                           TAG                 IMAGE ID            CREATED             SIZE
istio/examples-helloworld-v2         latest              2c7736ccfb8b        45 seconds ago      713MB
istio/examples-helloworld-v1         latest              20be3b24eab7        46 seconds ago      713MB

3、镜像发到其他节点

# 备份镜像
sudo docker save -o hello1.tar 20be3b24eab7
sudo docker save -o hello2.tar 2c7736ccfb8b

# 镜像发送到其他3个节点，并导入
# 对于每个节点做下面的操作
scp -i ~/hwk8s.pem hello1.tar root@192.168.1.229:~/
scp -i ~/hwk8s.pem hello2.tar root@192.168.1.229:~/

ssh -i 192.168.1.229

sudo docker load -i hello1.tar
sudo docker tag 20be3b24eab7 istio/examples-helloworld-v1:latest

sudo docker load -i hello2.tar
sudo docker tag 2c7736ccfb8b istio/examples-helloworld-v2:latest

exit

4、部署helloworld

kubectl apply -f helloworld.yaml
service/helloworld created
deployment.apps/helloworld-v1 created
deployment.apps/helloworld-v2 created

kubectl apply -f helloworld-gateway.yaml
gateway.networking.istio.io/helloworld-gateway created
virtualservice.networking.istio.io/helloworld created

kubectl get pods
kubectl get deployments

5、测试并生成流量

# 设置环境变量
# 这里IP要选用内网IP
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].nodePort}')
export GATEWAY_URL=192.168.1.124:$INGRESS_PORT

# 测试一下，会发现两次访问会用不同版本的服务
curl http://$GATEWAY_URL/hello
Hello version: v1, instance: helloworld-v1-5b75657f75-9dss5
curl http://$GATEWAY_URL/hello
Hello version: v2, instance: helloworld-v2-7855866d4f-rd2tr

# 也可以在外网，通过浏览器浏览
# 这里IP要选用外网IP
# 同样的，刷新浏览器会在不同版本服务之间切换
http://159.138.135.216:INGRESS_PORT/hello

# 生成访问流量
./loadgen.sh

6、使用kiali查看相关信息

#kiali 20001
istioctl dashboard kiali

#按上一节方法修改nginx配置内部端口
#重新加载配置
nginx -s reload

# 浏览器访问
http://159.138.135.216:8000

7、其他dashboard信息也可以用相同方法访问

#grafana 3000
istioctl dashboard grafana
#jaeger  16686
istioctl dashboard jaeger
#kiali 20001
istioctl dashboard kiali
#prometheus 9090
istioctl dashboard prometheus
#podid 9876
istioctl dashboard controlz podid
#podid 15000
istioctl dashboard envoy podid
#zipkin
istioctl dashboard zipkin

#按上一节方法修改nginx配置内部端口
#重新加载配置
nginx -s reload

# 浏览器访问
http://159.138.135.216:8000

#告知istio，对default空间下的pod自动注入Envoy sidecar
kubectl label namespace default istio-injection=enabled
namespace/default labeled

3、部署demo

#部署
kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml

#查看pods情况
kubectl get pods
NAME                              READY   STATUS    RESTARTS   AGE

reviews-v3-7f66977689-ccp9c       2/2     Running   0          106s

#查看services情况
kubectl get services
NAME          TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
details       ClusterIP   10.104.68.235   &amp;amp;amp;amp;lt;none&amp;amp;amp;amp;gt;        9080/TCP   89s

# 开启外部访问
kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
gateway.networking.istio.io/bookinfo-gateway created
virtualservice.networking.istio.io/bookinfo created

#查看gateway情况
kubectl get gateway
NAME               AGE
bookinfo-gateway   7s

4、设置ingress

# 查看是否配置了外部IP
kubectl get svc istio-ingressgateway -n istio-system
NAME                   TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                                                                                                                                      AGE
istio-ingressgateway   LoadBalancer   10.105.220.60   &amp;amp;amp;amp;lt;pending&amp;amp;amp;amp;gt;     15020:32235/TCP,80:30266/TCP,443:30265/TCP,15029:30393/TCP,15030:30302/TCP,15031:30789/TCP,15032:31411/TCP,31400:30790/TCP,15443:31341/TCP   5m30s&amp;amp;amp;amp;lt;/pending&amp;amp;amp;amp;gt;

#使用node的地址作为host，和LB只需要配置一种
export INGRESS_HOST=47.57.158.253

#使用LB的地址作为host，和node只需要配置一种
export INGRESS_HOST=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

#配置http端口
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].nodePort}')

#配置https端口
export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].nodePort}')

#设置并查看外部访问地址
export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT
echo http://$GATEWAY_URL/productpage

#此时就可以通过节点的ip地址来访问部署的实例了
#浏览器打开上面输出的地址
#http://47.57.158.253:30266/productpage

5、开启管理页面

#开始kaili
istioctl dashboard kiali

#安装nginx
#并设置反向代理
vi /etc/nginx/nginx.conf
http {

  upstream backend {
    # 代理的本地端口
    server 127.0.0.1:20001;
  }

  server {
    # 访问的外部端口
    listen 8000;
    location / {
      proxy_pass http://backend;
    }
  }

}

# 通过反向代理的8000端口就可以访问kiali的管理界面了
# #http://47.57.158.253:8000

PS:
必须开放的TCP端口有：

8000	nginx代理端口
8001	k8s默认代理端口
30266	bookinfo demo端口，会变更
