[自动化]基于kolla的自动化部署ceph集群
作者：互联网
kolla-ceph来源：
项目中的部分代码来自于kolla和kolla-ansible
kolla-ceph的介绍:
1、镜像的构建很方便, 基于容器的方式部署，创建、删除方便
2、kolla-ceph的操作幂等，多次执行不会产生副作用
3、使用kolla-ceph(基于ansible)流程化部署
4、通过给磁盘打上相应标签，创建osd非常简单
5、升级便捷，通过构建新的ceph镜像，upgrade既可
6、自动根据osd节点数量来设置故障域: "osd" 或 "host",及配置对应的副本数

环境: 3台虚拟机(可采用单节点或多节点)，下载Auto_Ceph项目放在/root/目录下
ceph集群节点规划、网络规划
vi /root/Auto_Ceph/00-hosts
# storage_interface=eth0 ceph集群管理接口，必须配置
# cluster_interface=eth1 ceph集群数据同步接口，为空默认就是storage_interface

下载ceph镜像<部署节点操作>
部署节点：可以是任意一台mon组的节点（172.20.163.244）
- 在线部署: 下载ceph镜像、安装ansible、kolla-ceph<部署节点操作>
1. type wget || yum install wget -y
2. wget https://bootstrap.pypa.io/pip/2.7/get-pip.py --no-check-certificate
3. python get-pip.py
4.ceph镜像下载安装依赖
pip install -r /root/Auto_Ceph/requirements.txt --ignore-installed
当出现以下报错的时候执行：pip install GitPython, 再执行pip install kolla==9.4.0
ERROR: pip's legacy dependency resolver does not consider dependency conflicts when selecting packages. This behaviour is the source of the following dependency conflicts.
gitdb2 4.0.2 requires gitdb>=4.0.1, but you'll have gitdb 0.6.4 which is incompatible.
gitpython 2.1.15 requires gitdb2<3,>=2, but you'll have gitdb2 4.0.2 which is incompatible.
5. 下载docker
sh /root/Auto_Ceph/bin/install -D
6. 运行docker
sh /root/Auto_Ceph/bin/install -I
systemctl status docker
7. 下载registry
sh /root/Auto_Ceph/bin/install -R
8. 运行registry
docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest
7. 修改配置
vi /root/Auto_Ceph/build/ceph-build.conf
registry = 172.17.2.179:5000 # 必须按照实际修改, 其它默认既可
8. 开始构建ceph镜像, 查看镜像
cd /root/Auto_Ceph/build/ && sh build.sh --tag nautilus

部署ceph集群
1. 修改参数<部署节点操作>
vi /root/Auto_Ceph/config/globals.yml
ceph_tag: "nautilus"
docker_registry: "仓库地址:端口"
ceph_osd_store_type: "bluestore"
ceph_pool_pg_num: 32 # 设置你的pg数
ceph_pool_pgp_num: 32 # 设置你的pgp数
enable_ceph_rgw: "true or false"
enable_ceph_mds: "true or false"
2. kolla-ceph部署使用<部署节点操作>
2.1 初始化ceph主机节点
kolla-ceph -i /root/Auto_Ceph/00-hosts os
2.2 部署前检查配置
kolla-ceph -i /root/Auto_Ceph/00-hosts prechecks
2.3 部署ceph集群
1、bluestore osd: 为每个osd节点的磁盘打上标签
parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS 1 -1
2、部署ceph-mon、ceph-osd、ceph-mgr、ceph-rgw、ceph-mds
kolla-ceph -i /root/Auto_Ceph/00-hosts deploy
3、docker exec ceph_mon ceph -s
cluster:
id: 4a9e463a-4853-4237-a5c5-9ae9d25bacda
health: HEALTH_OK
services:
mon: 3 daemons, quorum 172.20.163.67,172.20.163.77,172.20.163.238 (age 2h)
mgr: 172.20.163.238(active, since 2h), standbys: 172.20.163.77, 172.20.163.67
mds: cephfs:1 {0=devops2=up:active} 2 up:standby
osd: 4 osds: 4 up (since 2h), 4 in (since 13d)
rgw: 1 daemon active (radosgw.gateway)
data:
pools: 7 pools, 104 pgs
objects: 260 objects, 7.6 KiB
usage: 4.1 GiB used, 76 GiB / 80 GiB avail
pgs: 104 active+clean
2.4 删除操作: ceph集群容器和volume
kolla-ceph -i /root/Auto_Ceph/00-hosts destroy --yes-i-really-really-mean-it
2.5 升级操作
1、cd /root/Auto_Ceph/build/ && sh build.sh --tag new_ceph_version
2、修改最新ceph_tag: "new_ceph_version"
3、kolla-ceph -i /root/Auto_Ceph/00-hosts upgrade
2.6 单独更换部署osd
kolla-ceph -i /root/Auto_Ceph/00-hosts -t ceph-osd
2.7 开启ceph dashborad
enable_ceph_dashboard: true
kolla-ceph -i /root/Auto_Ceph/00-hosts start-dashborad
2.8 启用对象网关管理前端
enable_ceph_rgw: true
kolla-ceph -i /root/Auto_Ceph/00-hosts start-rgw-front
3. 磁盘打标签介绍
3.1. bluestore wal db共用一块盘打标签方式
- parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS 1 -1
3.2. bluestore 分离db和wal打标签方式
为了提高 ceph 性能,且ssd磁盘数量有限，通常将db和wal存放在单独的 ssd 磁盘上
# SSD磁盘：vdb vdd HDD磁盘：vdc
1. 指定元数据分区
parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS_BLUE1 1 100
2. 指定block 分区
parted /dev/vdc -s -- mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS_BLUE1_B 101 100%
3. 指定block.wal分区
parted /dev/vdb -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS_BLUE1_W 1 1000
4. 指定block.db分区
parted /dev/vdd -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS_BLUE1_D 1 10000
block.db 分区的大小为 block 分区 的 4%大小
3.3 filestore 打标签方式
- parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP 1 -1
3.4 filestore 指定日志单独分区
filestore 为了提高 ceph 性能，通常将日志存放在单独的 ssd 磁盘上
# SSD磁盘：vdb HDD磁盘：vdc vdd
1. vdc 作为数据盘
parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FILE1 1 -1
2. vdd 作为数据盘
parted /dev/vdd -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FILE2 1 -1
3. vdb作为vdc、vdd 的journal盘
parted /dev/vdb -s -- mklabel gpt
parted /dev/vdb -s -- mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FILE1_J 4M 2G
parted /dev/vdb -s -- mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FILE2_J 2G 4G
运维操作
1、任意一台montior节点进入ceph环境. 既可以正常执行ceph命令运维操作
docker exec -it ceph_mon bash
ceph -s
2、或者直接外部操作
docker exec ceph_mon ceph -s
3、osd故障操作
docker exec ceph_mon ceph osd crush rm osd.1
docker exec ceph_mon ceph osd auth rm osd.1
docker exec ceph_mon ceph osd rm osd.1
到故障osd节点把容器给干掉,然后换新盘: docker rm -f ceph_osd_1
为新磁盘盘打标签: parted /dev/vdc -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_BS 1 -1
部署新osd: kolla-ceph -i /root/Auto_Ceph/00-hosts -t ceph-osd
ceph dashboard
ceph 集群状态
ceph rgw
