Ceph部署Client及关联集群(octopus版)

1、安装依赖程序Python3：yum install -y python3

2、从主服务器上获取脚本：scp root@192.168.80.245:/root/cephadm /root/

3、配置脚本可执行权限：chmod +x cephadm    #已有执行权限此步骤可忽略

4、安装添加仓库源：
./cephadm add-repo –release octopus    #添加Ceph镜像源地址
cp /etc/yum.repos.d/ceph.repo{,.bak}    #备份镜像源地址
sed -i ‘s#download.ceph.com#mirrors.aliyun.com/ceph#’ /etc/yum.repos.d/ceph.repo    #修改镜像源为国内阿里云地址

[root@kvm ~]# ./cephadm add-repo --release octopus
Writing repo to /etc/yum.repos.d/ceph.repo...
Enabling EPEL...
[root@kvm ~]# cp /etc/yum.repos.d/ceph.repo{,.bak}
[root@kvm ~]# sed -i 's#download.ceph.com#mirrors.aliyun.com/ceph#' /etc/yum.repos.d/ceph.repo

5、安装ceph-common：yum install -y ceph-common

6、从主服务器上拷贝集群配置文件及认证文件：
scp root@192.168.80.245:/etc/ceph/ceph.conf /etc/ceph/
scp root@192.168.80.245:/etc/ceph/ceph.client.admin.keyring /etc/ceph/

7、验证：ceph -s

[root@kvm ~]# ceph -v
ceph version 15.2.9 (357616cbf726abb779ca75a551e8d02568e15b17) octopus (stable)
