如何实现基于cman+rgmanage+gfs2+iscsi+rbd 高可用文件共享环境搭建,针对这个问题,这篇文章详细介绍了相对应的分析和解答,希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
说明:rbd以iscsi方式导出作为共享存储。Iscsi target为10.20.18.111 iscsi intinator为10.20.15.163和10.20.15.164。cman+rgmanager管理nfs-server集群,gfs2为集群文件系统,管理集群内文件的并行操作。

(两个节点都配置)
# yum install cman rgmager -y

# yum install gfs2-utils
# mkfs.gfs2 -j 2 -p lock_dlm -t tcluster:sda dev/sda
备注:gfs为日志文件系统,每个节点都要有一个日志,本次实验有两个节点,所以创建两个日志。tcluster为集群名称、sda为锁表名称。
# mount –t gfs2 –o _netdev,nodiratime,noatime /dev/sda /mnt
# yum install -y lvm2-cluster
# lvmconf --enable-cluster
# service clvmd start
# pvcreate /dev/sda 创建物理卷 # vgcreate clustervg /dev/sda 创建卷组 # lvcreate -L 500M -n clusterlv clustervg 创建逻辑卷 # mkfs.gfs2 -j 2 -p lock_dlm -t tcluster:lv /dev/clustervg/clusterlv # mount /dev/clustervg/clusterlv /mnt
# yum -y install nfs-utils rpcbind # yum install nfs-utils
2. NFS的配置文件定义: /etc/exports
# vim /etc/exports /mnt 10.20.*.*(rw,no_root_squash,no_all_squash,sync)
注:配置文件说明:
/mnt 为共享的目录,即rbd所挂目录,使用绝对路径.10.20.*.*允许客户端访问的IP,()里面为权限控制。
# service rpcbind start # service nfs start
# mkdir /usr/local/nfstest
#配置生效
# exportfs -rv
# showmount -e 10.20.16.177
# mount -t nfs 10.20.16.177:/mnt /usr/local/nfstest
# yum install samba samba-client samba-swat
(无需客户端密码验证的简单配置)
# vi /etc/samba/smb.conf [global] //该设置与Samba服务整体运行环境有关,它的设置项目针对所有共享资源
# ----------------------- Network Related Options ------------------------- # # workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH # # server string is the equivalent of the NT Description field # # netbios name can be used to specify a server name not tied to the hostname workgroup = WORKGROUP //定义工作组,也就是windows中的工作组概念 server string = David Samba Server Version %v //定义Samba服务器的简要说明 netbios name = DavidSamba //定义windows中显示出来的计算机名称 # --------------------------- Logging Options ----------------------------- # # Log File let you specify where to put logs and how to split them up. log file = /var/log/samba/log.%m //定义Samba用户的日志文件,%m代表客户端主机名 //Samba服务器会在指定的目录中为每个登陆主机建立不同的日志文件 # ----------------------- Standalone Server Options ------------------------ # # Scurity can be set to user, share(deprecated) or server(deprecated) security = share //共享级别,用户不需要账号和密码即可访问 #============================ Share Definitions ============================== [public] //设置针对的是共享目录个别的设置,只对当前的共享资源起作用 comment = Public Stuff //对共享目录的说明文件,自己可以定义说明信息 path = /mnt //用来指定共享的目录,必选项 public = yes //所有人可查看,等效于guest ok = yes
