7)所有节点安装python2

3、ceph部署
#配置ceph仓库
sudo echo "deb https://mirrors.tuna.tsinghua.edu.cn/ceph/debian-pacific bionic main" >> /etc/apt/sources.list
#导入key
wget -q -O- 'https://mirrors.tuna.tsinghua.edu.cn/ceph/keys/release.asc' | sudo apt-key add -
#更新仓库源
apt update
推荐使用指定的普通用户部署和运行ceph 集群，普通用户只要能以非交互方式执行命令执行一些特权命令即可，新版的ceph-deploy 可以指定包含root 的在内只要可以执行 命令的用户，不过仍然推荐使用普通用户，比如ceph、cephuser、cephadmin 这样的用户去管理ceph 集群。
#因为前面安装的ceph-common会更改ceph用户的家目录，建议使用其它用户来部署，如cephadmin用户
groupadd -r -g 2021 cephadmin && useradd -r -m -s /bin/bash -u 2021 -g 2021 cephadmin && echo cephadmin:123456 | chpasswd
#允许ceph 用户以 执行特权命令
echo "cephadmin ALL=(ALL) NOPASSWD:ALL" >> /etc/ers
在ceph-deploy 节点配置允许以非交互的方式登录到各ceph node/mon/mgr 节点，即在ceph-deploy 节点的ceph用户生成秘钥对，然后分发公钥到各被管理节点的ceph用户。

验证在mon 定节点已经自动安装并启动了ceph-mon 服务，并且后期在ceph-deploy 节点初始化目录会生成一些bootstrap ceph mds/mgr/osd/rgw 等服务的keyring 认证文件，这些初始化文件拥有对ceph 集群的最高权限，所以一定要保存好。
root@ceph-mon01:~# ps -ef|grep ceph-mon ceph 8304 1 0 22:43 ? 00:00:00 /usr/bin/ceph-mon -f --cluster ceph --id ceph-mon01 --setuser ceph --setgroup ceph
在ceph-deploy 节点把配置文件和admin 密钥拷贝至Ceph 集群需要执行ceph 管理命令的节点，从而不需要后期通过ceph 命令对ceph 集群进行管理配置的时候每次都需要指定ceph-mon 节点地址和ceph.client.admin.keyring 文件,另外各ceph-mon 节点也需要同步ceph 的集群配置文件与认证文件。
如果在ceph-deploy 节点管理集群
root@ceph-deploy:~# apt install ceph-common -y #先安装ceph 的公共组件 root@ceph-node01:~# apt install ceph-common -y root@ceph-node02:~# apt install ceph-common -y root@ceph-node03:~# apt install ceph-common -y root@ceph-node04:~# apt install ceph-common -y
拷贝密钥到ceph-node01 ceph-node02 ceph-node03 ceph-node04

1、磁盘有数据
处理方案：清空磁盘数据，实验中的操作是关闭虚拟机，删除原磁盘，重新添加磁盘。

1)、安装ceph-mds软件包
如果要使用cephFS，需要部署cephfs 服务。MDS服务与mon服务部署在一起（最好分开部署）。
apt install ceph-mds
在ceph-deploy上操作
ceph-deploy mds create ceph-mds01 ceph-deploy mds create ceph-mds02 ceph-deploy mds create ceph-mds03
#创建cephfs-metadata cephadmin@ceph-deploy:~/ceph-cluster$ ceph osd pool create cephfs-metadata 32 32 pool 'cephfs-metadata' created #保存metadata 的pool #创建cephfs-data cephadmin@ceph-deploy:~/ceph-cluster$ ceph osd pool create cephfs-data 64 64 pool 'cephfs-data' created #保存数据的pool #创建一个叫mycephfs的cephFS cephadmin@ceph-deploy:~/ceph-cluster$ ceph fs new mycephfs cephfs-metadata cephfs-data new fs with metadata pool 2 and data pool 3

5)、MDS的高可用
为了测试，我们把ceph-mgr02复用为mds
#添加第4台mds ceph-mgr02
#在ceph-mgr02上安装ceph-mds
root@ceph-mgr02:~# apt install ceph-mds
#在ceph-deploy上把mgr02添加进mds

设置每个Rank 的备份MDS，也就是如果此Rank 当前的MDS 出现问题马上切换到另个MDS。设置备份的方法有很多，常用选项如下。
mds_standby_replay：值为true 或false，true 表示开启replay 模式，这种模式下主MDS 内的数量将实时与从MDS 同步，如果主宕机，从可以快速的切换。如果为false 只有宕机的时候才去同步数据，这样会有一段时间的中断。 mds_standby_for_name：设置当前MDS 进程只用于备份于指定名称的MDS。 mds_standby_for_rank：设置当前MDS 进程只用于备份于哪个Rank，通常为Rank 编号。另外在存在之个CephFS 文件系统中，还可以使用mds_standby_for_fscid 参数来为指定不同的文件系统。 mds_standby_for_fscid：指定CephFS 文件系统ID，需要联合mds_standby_for_rank 生效，如果设置mds_standby_for_rank，那么就是用于指定文件系统的指定Rank，如果没有设置，就是指定文件系统的所有Rank。
