CentOS7 glusterfs 安装设置

CentOS 7 安装glusterfs 文件系统

1. 增加gluster 源

     wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo
         
     mv glusterfs-epel.repo /etc/yum.repos.d/
         
   

1. 安装对应的包

      yum install -y glusterfs glusterfs-server glusterfs-fuse
          
   

   查看selinux 配置, 注意选择permissive或者disabled

   1. 启动服务

      service glusterd   start
      service glusterfsd start
             
      

   2. 配置集群、查看集群中的节点

      gluster peer probe node01
      gluster peer probe node02
            
      gluster pool list
      

   3. 创建一个数据目录,gluster volume

         mkdir -p /opt/data
                 
         #系统会提示,因为你在root partition上做gluster volume, 需要使用force
         #The brick server01:/opt/data is being created in the root partition. It is recommended that you don't use the system's root partition for storage backend. Or use 'force' at the end of the command if you want to override this behavior.
         gluster volume create kube_vol server01:/opt/data
                 
         gluster volume create kube_vol server01:/opt/data force
         gluster volume start kube_vol
         gluster volume info
                    
      

   4. 使用gluster 创建的卷

      mkdir /mnt/glusterfs
             
      mount -t glusterfs server:/kube_vol /mnt/glusterfs
             
      #测试读写
      dd if=/dev/sda of=/mnt/glusterfs/1.bin bs=1M count 20
