1. 安装ceph-fuse

yum install -y ceph-fuse

如果安装失败，先执行以下命令，再执行上述安装命令

yum -y install epel-release


rpm -Uhv http://download.ceph.com/rpm-jewel/el7/noarch/ceph-release-1-1.el7.noarch.rpm

2. 配置客户端访问的key

mkdir /etc/ceph/ vi /etc/ceph/ceph.client.admin.keyring

[client.admin]
key = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx==

3. ceph-fuse 挂载

ceph-fuse -m <mons_IP1>:6789,<mons_IP2>:6789,<mons_IP3>:6789 -r <ceph集群中的目录> <宿主机目录> -o nonempty

例如：

# ceph-fuse -m 192.168.18.3:6789,192.168.18.4:6789,192.168.18.5:6789 -r /pvc-volumes /root/cephfsdir -o nonempty
2019-03-27 17:58:04.435985 7fc61b67cec0 -1 did not load config file, using default settings.
ceph-fuse[18051]: starting ceph client
2019-03-27 17:58:04.469144 7fc61b67cec0 -1 init, newargv = 0x55cecaba81c0 newargc=13
ceph-fuse[18051]: starting fuse

4. 查看是否挂载成功

# df -h
Filesystem Size Used Avail Use% Mounted on
...
ceph-fuse 1.6T  8.8G  1.6T   1% /root/cephfsdir
