ceph端口访问控制
成都ceph环境做为数据备份空间,因未启用授权机制,为确保数据安全,现已添加端口访问控制。
若需增加访问点请在172.17.35.241:/usr/local/bin/default.iptables中进行设置:

# 若增加ceph节点,请将节点ip添加到LAN_IPs中 LAN_IPs=172.17.35.240,172.17.35.241,172.17.35.242,172.17.35.243 # 若增加访问客户端,请将客户端IP添加到CEPH_IPs中 CEPH_IPs= "$NMC_IPs,172.17.46.0/24"
CEPH_IPs= "$CEPH_IPs,192.168.0.131,192.168.0.133,192.168.0.233,192.168.0.23,192.168.0.247"
# 修改完成default.iptables后,执行下面的命令加载策略: setiptables.sh load default.iptables |
用Kernel方式挂载
该方式需要更换系统内核、并重启系统以支持ceph文件系统挂载。
经试用以方式挂载后,存在某些目录丢失,重新mount后丢失目录又出现的现象,而使用fuse方式挂载未发生这一现象。
安装ELRepo及kernel-lt

# 首先你要做的就是导入public key #rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -- import http: //www .elrepo.org /RPM-GPG-KEY-elrepo .org
# 然后安装ELRepo到CentOS-6.5中 rpm -ivh http: //www .elrepo.org /elrepo-release-6-5 .el6.elrepo.noarch.rpm
# 安装kernel-lt(lt=long-term) yum --enablerepo=elrepo-kernel install kernel-lt -y
# 你也可以装kernel-ml(ml=mainline)kernel-lt、kernel-mt二者选一个就可以了! #yum --enablerepo=elrepo-kernel install kernel-ml -y |
修改Grub引导顺序并重启动
vim/etc/grub.conf
设置default值(从0开始),一般新安装的内核在第一个位置,所以设置default=0。
目前内核为:title CentOS (3.10.59-1.el6.elrepo.x86_64)
重启,这时候你的内核就成功升级了,你可以删除你的旧内核了!
- 重启后内核为:
uname -a Linux yunwei2.timait 3.10.59-1.el6.elrepo.x86_64 #1 SMP Thu Oct 30 23:46:31 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
- 重启失败参考(经在192.168.0.82上测试此方法无效)
CentOS 6 will not boot on KVM with elrepo kernel 3.13 / 3.14
You can work around it by booting into your working stock kernel and running these two commands:

yum install -y device-mapper-libs libudev
for X in $( cd /boot ; ls -1 config-*elrepo* | sed 's/config-//' ) ; do dracut --add-drivers virtio_blk -f /boot/initramfs- $X.img $X ; done

添加ceph源
公司内部源、第三方源选择添加一个即可。
- 公司内部源
内部源ceph版本为:0.67.5-16.g69a99e6.el6

安装ceph客户端

|
yum -y install ceph
|
[root@FTP-Maven ~]# rpm -qa|grep ceph libcephfs1-0.67.5-16.g69a99e6.el6.x86_64 python-ceph-0.67.5-16.g69a99e6.el6.x86_64 ceph-0.67.5-16.g69a99e6.el6.x86_64
挂载ceph卷
- 命令行挂载

2
|
mkdir -p /cephdata
mount -t ceph 172.17.35.241:6789:/ /cephdata
|
- 添加/etc/fstab自动挂载

|
#172.17.35.241:6789:/ /cephdata 172.17.35.241:6789:/ /cephdata ceph defaults 0 0
|
- 注意:开启SELinux可能引起挂载ceph卷后进入子目录报没有权限错误。
fuse方式挂载ceph卷
因ceph-fuse使用64位的inode,在32位系统中会出现问题,因此仅限在64位系统中使用。
安装epel源

yum -y install epel-release
# epel-release-6-8.noarch |
若安装后yum工作异常,修改/etc/yum.repos.d/epel.repo,取消mirrorlist、启用baseurl即可。

- 建立挂载点目录

|
mkdir -p /mnt/cephdata_backups
|
- 设置/etc/fstab

# 设置挂载ceph中的backups目录 m=172.17.35.241:6789,r= /backups /mnt/cephdata_backups fuse.ceph defaults 0 0

mount /mnt/cephdata_backups
umount /mnt/cephdata_backups

- 基于ceph集群未正常的情况下,openstack集群开机自mount时该机器会无法启动,当前先去掉该自动mount,改为手动方式
