虚机开启selinux:
vi /etc/selinux/config
设置:
SELINUX=enforcing
设置目录权限:
mkdir -p /etc/ceph
mkdir -p /var/lib/ceph
chcon -Rt svirt_sandbox_file_t /etc/ceph
chcon -Rt svirt_sandbox_file_t /var/lib/ceph
如果系统只有一个数据盘,并且数据盘已经分区,需要对数据盘进行分区删除,并进行格式化处理。
格式化命令如下:
mkfs.ext4 /dev/vdb
下面我们采用docker进行安装,ceph/daemon的版本为tag-build-master-jewel-centos-7。
启动monitor:
docker run -d --name=mon --net=host \
--restart=always \
-v /etc/ceph:/etc/ceph \
-v /var/lib/ceph:/var/lib/ceph \
-e MON_IP=192.168.0.1 \
-e CEPH_PUBLIC_NETWORK=192.168.0.0/24 \
ceph/daemon:tag-build-master-jewel-centos-7 mon
