项目笔记：3.利用分布试存储(glusterfs)实现页面一致性






1、在192.168.0.4和192.168.0.5上安装glusterfs服务端并导出raid1+0分布式存储

# yum -y install glusterfs glusterfs-fuse glusterfs-server  --<span style="font-size:18px;">glusterfs 的yum源之前讲过怎么搭建的</span>

# /etc/init.d/glusterd start
# chkconfig glusterd on
------------------------------------以上内容两个节点都要操作------------------------------------------

以下内容单节点做了会自动同步

# gluster peer probe vm05.kong.com		--在192.168.0.4上操作链接0.5那台机
peer probe: success.

# gluster peer status
Number of Peers: 1

Hostname: vm05.kong.com
Uuid: f91baacf-b12d-4c4d-9d7b-b8aed89baff1
State: Peer in Cluster (Connected)

# gluster volume create glusterfs stripe 2 replica 2  vm04.kong.com:/strip-rep01 vm04.kong.com:/strip-rep02 vm05.kong.com:/strip-rep01 vm05.kong.com:/strip-rep02 force

# gluster volume info

Volume Name: glusterfs
Type: Striped-Replicate
Volume ID: b49aabc2-8338-4b05-a9e6-d3b5da930d30
Status: Created
Number of Bricks: 1 x 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: vm04.kong.com:/strip-rep01
Brick2: vm04.kong.com:/strip-rep02
Brick3: vm05.kong.com:/strip-rep01
Brick4: vm05.kong.com:/strip-rep02

# gluster volume start glusterfs

2、在192.168.0.2和192.168.0.3上安装glusterfs客户端

# yum -y install glusterfs glusterfs-fuse
------------------------------以上两个节点都要操作，记得搭建glusterfs 的yum源----------------------------

在其中一个节点上挂载，并且迁移网页

# service tomcat stop
# service nginx stop
# mount.glusterfs 192.168.0.4:/glusterfs /mnt
# cp -av /var/www/html/* /mnt
# umount /mnt  --迁移到共享存储
# mount.glusterfs 192.168.0.4:/glusterfs /var/www/html/ --使用共享存储
# service tomcat start
# service nginx start

在另一个节点上做以下操作

# service tomcat stop && service nginx stop
# mount.glusterfs 192.168.0.5:/glusterfs /var/www/html/
# service tomcat start
# service nginx start
