一、环境信息 node1 192.168.8.11 两块磁盘 node2 192.168.8.12 两块磁盘 node3 192.168.8.13 两块磁盘 node4 192.168.8.14 两块磁盘 node5 192.168.8.15 两块磁盘 node6 192.168.8.16 两块磁盘 二、通用配置（各个节点） 1、修改主机名 hostnamectl set-hostname node1 2、修改hosts文件 # cat <<"EOF">/etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.8.11 node1 192.168.8.12 node2 192.168.8.13 node3 192.168.8.14 node4 192.168.8.15 node5 192.168.8.16 node6 EOF 3、配置源 # cat <<END >/etc/yum.repos.d/repo.repo [repo] name=repo baseurl = https://mirrors.tuna.tsinghua.edu.cn/centos/7/storage/x86_64/gluster-6/ enabled=1 gpgcheck=0 END 4、安装NTP（各个节点） # yum -y install ntp 修改配置文件/etc/ntp.conf server <NTP-server> **注意： ** NTP-server修改为自己的NTP服务器，如果局域网内无NTP服务器，此处可以用默认配置，采用centos官方ntp服务器 5、启动ntpd服务并设置开机启动 # systemctl start ntpd # systemctl enable ntpd 查看ntp状态 # ntpq -p 6、配置防火墙 # firewall-cmd --add-service=ntp --permanent success # firewall-cmd --reload success 7、安装软件包 # yum -y install glusterfs-server 8、启动服务并设置开机启动 # systemctl start glusterd # systemctl enable glusterd 9、查看版本 # gluster --version glusterfs 6.4 Repository revision: git://git.gluster.org/glusterfs.git Copyright (c) 2006-2016 Red Hat, Inc. <https://www.gluster.org/> GlusterFS comes with ABSOLUTELY NO WARRANTY.
