CentOS7 安装 Ceph-201并创建一个高可以集群

以下是 CentOS7 安装 Ceph-2.0.1 并创建一个高可用集群的步骤：

1. 首先，安装 Ceph 依赖库：

sudo yum install -y epel-release
sudo yum install -y wget git vim ntp ntpdate ntp-doc openssh-server openssh-clients openssl-devel libevent libevent-devel libffi libffi-devel python-devel python-pip python-setuptools python-argparse python-crypto python-jinja2 python-six python-rados python-rbd python-ceph librados2 librados2-devel librbd1 librbd1-devel ceph-fuse libradosstriper1 libradosstriper1-devel python-cephfs librados2-python librbd1-python ceph-fuse python-cephfs radosgw librados2-python-devel librados2-devel librbd1-python-devel ceph-base ceph-common ceph-osd ceph-mds ceph-mon

2. 下载 Ceph-2.0.1 源码包：

wget https://download.ceph.com/tarballs/ceph-2.0.1.tar.gz
tar -zxvf ceph-2.0.1.tar.gz
cd ceph-2.0.1/

3. 编译安装 Ceph：

./install-deps.sh
./autogen.sh
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --with-radosgw --with-debug --with-libevent=internal
make -j8
sudo make install

4. 创建 Ceph 配置文件：

sudo mkdir /etc/ceph
sudo cp ceph.conf.sample /etc/ceph/ceph.conf
sudo chown ceph:ceph /etc/ceph/ceph.conf

5. 创建 Ceph 存储池：

sudo ceph osd pool create mypool 64

6. 创建 Ceph 文件系统：

sudo ceph osd pool create cephfs_data 64
sudo ceph osd pool create cephfs_metadata 64
sudo ceph fs new cephfs cephfs_metadata cephfs_data

7. 启动 Ceph 服务：

sudo systemctl start ceph-mon.target
sudo systemctl start ceph-osd.target
sudo systemctl start ceph-mds.target
sudo systemctl start ceph-radosgw.target

8. 查看 Ceph 集群状态：

sudo ceph -s

至此，你已经成功安装并创建了一个 Ceph 高可用集群。
