glusterfs部署及使用
1.环境检查
1.1检查防火墙
systemctl stop firewalld #临时关闭防火墙
systemctl disable firewalld #永久关闭防火墙 reboot生效
1.2 检查selinux
setenforce 0 #临时关闭
vim /etc/selinux/config #永久关闭 reboot生效
SELINUX=disabled
1.3 检查系统磁盘
- 每个系统应该至少空余一块磁盘供glusterfs使用
- 参考命令 lsblk -d fdisk -l
[root@jdos-2-demo14 ~]# lsblk -d
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vdb 253:16 0 1000G 0 disk
vdc 253:32 0 100G 0 disk /node1
vda 253:0 0 200G 0 disk
2.部署
2.1 环境准备
| IP地址 |
roles |
磁盘 |
| 10.0.0.11 |
server |
100G |
| 10.0.0.12 |
server |
100G |
| 10.0.0.13 |
client |
|
2.2 server机器格式化
mkfs.xfs -f /dev/xxxxxx #磁盘名称
mkdir -p /node1 #创建挂载目录
lsblk #找到uuid号
[root@jdos-2-demo14 ~]# cat /etc/fstab | tail -1 #执行挂载动作
UUID="7836d51c-e915-4911-b82f-c2e366ee7803" /node1 xfs defaults 1 1
2.3 hosts 配置
vim /etc/hosts
10.0.0.11 glusterfs-server1
10.0.0.12 glusterfs-server2
1.0.0.13 glusterfs-srever3
#保存
scp -rp root@/etc/hosts/ root@glusterfs-server2:/etc/hosts
scp -rp root@/etc/hosts/ root@glusterfs-server3:/etc/hosts
2.4 部署软件
[root@jdos-2-demo14 ~]# mkdir -p /software
[root@jdos-2-demo16 software]# ls -l
