在ubuntu上安装部署ceph

 

1. 首先安装一个all-in-one的openstack环境

10.33.41.55上的hcloud-lxp：192.168.1.112  浮动IP:10.33.41.134

这里从ubuntu_1404_pure启动两个虚拟机，作为ceph的osd节点，而ceph的mon/mds节点使用all-in-one的环境

总结如下：

名称	hostname	固定IP	浮动IP	角色	备注
Hcloud-lxp	ubuntu	192.168.1.120	10.33.41.134	Openstack	从hcloud启动
lxp-ceph1	lxpnode1	192.168.11.6	10.33.41.135	Ceph mon	从ubuntu_1404_pure启动
lxp-ceph2	lxpnode2	192.168.11.7	10.33.41.136	Ceph osd1	从ubuntu_1404_pure启动
lxp-ceph3	lxpnode3	192.168.11.8	10.33.41.139	Ceph osd2	从ubuntu_1404_pure启动

将源配置成：

deb file:/opt/hCloud_Install debpackage/

 

这里openstack的环境就不要改了，因为改了这个hostname，很多config都要改，索性不改。

 

修改/etc/hostname和/etc/hosts

保存快照

关机，为ceph2、ceph3增加云硬盘，然后启动

将IP改成10.33.41网段

 

2. 安装ceph

接下来在lxp-ceph1、lxp-ceph2、lxp-ceph3搭建ceph环境

apt-get install ceph

apt-get install ceph-deploy

apt-get install-y ntp ntpdate ntp-doc

 

 

# cd /etc/ceph

# ceph-deploy new lxpnode1

修改配置：

root@lxpnode1:/etc/ceph# vi ceph.conf

[global]

fsid = 1d082422-3283-4df7-a444-355ff17076e0

mon_initial_members = lxpnode1

mon_host = 192.169.1.121

auth_cluster_required = cephx

auth_service_required = cephx

auth_client_required = cephx

filestore_xattr_use_omap = true

 

public network = 192.168.11.0/24

cluster network = 192.168.11.0/24

osd_pool_default_size = 2

~                             

# cd /etc/ceph

# ceph-deploy new lxpnode1

 

# ceph-deploy install lxpnode1 lxpnode2lxpnode3

# ceph-deploy --overwrite-conf   mon create-initial

#ceph-deploy mon create lxpnode1

# ceph-deploy gatherkeys lxpnode1

 

# scp -r /etc/ceph/ lxpnode2:/etc

# scp -r /etc/ceph/ lxpnode3:/etc

 

# mkdir -p /data/osd.0

# mkdir -p /data/osd.1

 

# ufw disable

# ceph-deploy osd prepare lxpnode2:/data/osd.0:/dev/vdblxpnode3:/data/osd.1:/dev/vdb

# ceph-deploy osd activate lxpnode2:/data/osd.0:/dev/vdblxpnode3:/data/osd.1:/dev/vdb

 

终于OK了！！！
