CentOS 6 部署GlusterFS
首先需要关闭CentOS的防火墙和selinux,否则glusterfs将可能无法正常工作。/etc/init.d/iptables status
会得到一系列信息，说明防火墙开着。
/etc/init.d/iptables stop
永久关闭:
chkconfig --level 35 iptables off
永久关闭SELinux
查看当前SELinux状态：/usr/bin/setstatus -v
编辑/etc/selinux/config，找到SELINUX 行修改成为：SELINUX=disabled:
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
重启系统。
1，将glusterfs的yum源加入到本机中 wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo2，通过glusterfs的yum源进行安装 yum -yinstall glusterfs{-fuse,-server,-geo-replication}3，启动glusterfs服务 service glusterd start4，将机器加入到glusterfs集群中 gluster peer probeip 5，单机环境准备 mkdir -p /home/glusterfs6，创建分布式卷，两副本 gluster volume create gfs replica 2 10.10.10.1:/home/glusterfs 10.10.10.2:/home/glusterfs 7，启动分布式卷 gluster volume start gfs8，查看状态 gluster volume info9，挂载分布式存储 mount -t glusterfs10.10.10.1:/gfs /home/share10，扩容(注意扩容的机器数量需要是副本数的整数倍) gluster volume add-brick gfs10.10.10.3:/home/glusterfs 10.10.10.4:/home/glusterfs 11，ACK控制（需要用逗号隔开） gluster volume set gfs auth.allow 10.10.10.5，10.10.10.612，开启quota gluster volume quotagfs enable/disable13，对某一分区开启quota限制1GB的空间，如果达到quota，则会直接报错Disk quota exceeded，无法继续写入 gluster volume quota gfs limit-usage /test-quota 1GB14，查询quota gluster volume quotagfslist15，删除quota gluster volume quotagfs remove/test-quota16，开启profile工具 gluster volume profile gfsstart/stop17，profile常用命令介绍 gluster volume profile gfsinfo18，删除卷 gluster volume stop gfs&&gluster volume delete gfs
