ceph分布式存储部署脚本
1、安装第一个mon节点cat > /etc/ceph/ceph.conf > /etc/fstab
echo "/dev/sdb /var/lib/ceph/osd/ceph-0xfs remount,user_xattr0 0" >> /etc/fstab
ceph-osd -i 0 --mkfs --mkkey
ceph auth add osd.0 osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/ceph-0/keyring
ceph osd crush add-bucket rack1 rack
ceph osd crush add-bucket os-node1 host
ceph osd crush move os-node1 rack=rack1
ceph osd crush move rack1 root=default
ceph osd crush add osd.0 1.0 host=os-node1
touch /var/lib/ceph/osd/ceph-0/sysvinit
/etc/init.d/ceph start osd.0
2、添加第二个osd节点
在os-node2节点
ceph osd create
mkdir -p /var/lib/ceph/osd/ceph-1
mkfs.xfs -f /dev/sdb
mount /dev/sdb /var/lib/ceph/osd/ceph-1
mount -o remount,user_xattr /var/lib/ceph/osd/ceph-1
echo "/dev/sdb /var/lib/ceph/osd/ceph-1xfs defaults 0 0" >> /etc/fstab
echo "/dev/sdb /var/lib/ceph/osd/ceph-1xfs remount,user_xattr0 0" >> /etc/fstab
ceph-osd -i 1 --mkfs --mkkey
ceph auth add osd.1 osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/ceph-1/keyring
ceph osd crush add-bucket rack2 rack
ceph osd crush add-bucket os-node2 host
ceph osd crush move os-node2 rack=rack2
ceph osd crush move rack2 root=default
ceph osd crush add osd.1 1.0 host=os-node2
touch /var/lib/ceph/osd/ceph-1/sysvinit
/etc/init.d/ceph start osd.1
2、添加第三个osd节点
在os-node3节点
ceph osd create
mkdir -p /var/lib/ceph/osd/ceph-2
mkfs.xfs -f /dev/sdb
mount /dev/sdb /var/lib/ceph/osd/ceph-2
mount -o remount,user_xattr /var/lib/ceph/osd/ceph-2
echo "/dev/sdb /var/lib/ceph/osd/ceph-2xfs defaults 0 0" >> /etc/fstab
echo "/dev/sdb /var/lib/ceph/osd/ceph-2xfs remount,user_xattr0 0" >> /etc/fstab
ceph-osd -i 2 --mkfs --mkkey
ceph auth add osd.2 osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/ceph-2/keyring
ceph osd crush add-bucket rack3 rack
ceph osd crush add-bucket os-node3 host
ceph osd crush move os-node3rack=rack3
ceph osd crush move rack3 root=default
ceph osd crush add osd.2 1.0 host=os-node3
touch /var/lib/ceph/osd/ceph-2/sysvinit
/etc/init.d/ceph start osd.2
添加元数据服务器
添加第一个元数据服务器
1、在os-node1节点
mkdir -p /var/lib/ceph/mds/ceph-os-node1
touch /root/ceph.bootstrap-mds.keyring
ceph-authtool --import-keyring /var/lib/ceph/bootstrap-mds/ceph.keyring ceph.bootstrap-mds.keyring
ceph --cluster ceph --name client.bootstrap-mds --keyring /var/lib/ceph/bootstrap-mds/ceph.keyring auth get-or-create mds.os-node1 osd 'allow rwx' mds 'allow' mon 'allow profile mds' -o /var/lib/ceph/mds/ceph-os-node1/keyring
touch /var/lib/ceph/mds/ceph-os-node1/sysvinit
touch /var/lib/ceph/mds/ceph-os-node1/done
service ceph start mds.os-node1
添加第二个元数据服务器
1、在os-node2节点
mkdir -p /var/lib/ceph/mds/ceph-os-node2
mkdir -p /var/lib/ceph/bootstrap-mds/
2、在os-node1节点
scp /var/lib/ceph/bootstrap-mds/ceph.keyring os-node2:/var/lib/ceph/bootstrap-mds/
scp /root/ceph.bootstrap-mds.keyring os-node2:/root/
scp /var/lib/ceph/mds/ceph-os-node1/sysvinit os-node2:/var/lib/ceph/mds/ceph-os-node2/
3、在os-node2节点
ceph --cluster ceph --name client.bootstrap-mds --keyring /var/lib/ceph/bootstrap-mds/ceph.keyring auth get-or-create mds.os-node2 osd 'allow rwx' mds 'allow' mon 'allow profile mds' -o /var/lib/ceph/mds/ceph-os-node2/keyring
touch /var/lib/ceph/mds/ceph-os-node2/done
service ceph start mds.os-node2
添加第三个元数据服务器
1、在os-node3节点
mkdir -p /var/lib/ceph/mds/ceph-os-node3
mkdir -p /var/lib/ceph/bootstrap-mds/
2、在os-node1节点
scp /var/lib/ceph/bootstrap-mds/ceph.keyring os-node3:/var/lib/ceph/bootstrap-mds/
scp /root/ceph.bootstrap-mds.keyring os-node3:/root/
scp /var/lib/ceph/mds/ceph-os-node1/sysvinit os-node3:/var/lib/ceph/mds/ceph-os-node3/
3、在os-node3节点
ceph --cluster ceph --name client.bootstrap-mds --keyring /var/lib/ceph/bootstrap-mds/ceph.keyring auth get-or-create mds.os-node3 osd 'allow rwx' mds 'allow' mon 'allow profile mds' -o /var/lib/ceph/mds/ceph-os-node3/keyring
touch /var/lib/ceph/mds/ceph-os-node3/done
service ceph start mds.os-node3
