安装xdata步骤

1.修改配置文件/etc/security/limits.conf

修改配置文件/etc/security/limits.conf
在该配置文件中添加：
vim /etc/security/limits.conf





* soft nofile 65535
* hard nofile 65535

修改之后重新SSH连接即可，不需要重启主机或服务

2. 禁用禁用SELINUX

永久性关闭selinux（重启服务器生效）


sed -i 's/SELINUX=enforcing/SELINUX =disabled/' /etc/selinux/config

检查：查看selinux状态，getenforce，permissive即为关闭，enforcing即为开启


getenforce

备注：临时关闭：setenforce 0

3.关闭防火墙

systemctl stop firewalld.service

systemctl disable firewalld.service

4.规划目录

在这里插入图片描述

5.配置pv，vg，并挂载对应目录

物理机实际硬盘

[root@localhost sdh]# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0 446.6G  0 disk

└─sda2        8:2    0 444.6G  0 part
  ├─cl-root 253:0    0   300G  0 lvm  /

sdc           8:32   0  22.9T  0 disk

将sdb和sdc分别创建

5.1 创建pv

 pvcreate  pvcreate /dev/sdb
 pvcreate  pvcreate /dev/sdc

[root@localhost sdh]# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sda2
  VG Name               cl
  PV Size               444.62 GiB / not usable 3.00 MiB
  Allocatable           yes (but full)
  PE Size               4.00 MiB
  Total PE              113822
  Free PE               0
  Allocated PE          113822
  PV UUID               6LMc3M-Xc9l-dpg8-H312-Y42A-XbvN-Bjtms0

  "/dev/sdb" is a new physical volume of "1.75 TiB"
  --- NEW Physical volume ---
  PV Name               /dev/sdb
  VG Name
  PV Size               1.75 TiB
  Allocatable           NO
  PE Size               0
  Total PE              0
  Free PE               0
  Allocated PE          0
  PV UUID               hQq2Be-vQgH-pROR-0c2n-cV8i-eowL-FuuyQ8

  "/dev/sdc" is a new physical volume of "22.92 TiB"
  --- NEW Physical volume ---
  PV Name               /dev/sdc
  VG Name
  PV Size               22.92 TiB
  Allocatable           NO
  PE Size               0
  Total PE              0
  Free PE               0
  Allocated PE          0
  PV UUID               iNaMcW-fLs5-TixD-ozTw-2yZ3-v2Ah-aJ0TVG

5.2 创建vg

vgcreate DATA-SSD /dev/sdb

vgcreate DATA-HDD /dev/sdc

5.3 lv操作

lvcreate -n data1 -L 1.7T DATA-SSD
lvcreate -n data2 -L 22T DATA-HDD


lvcreate -n data1 -L 3.4T DATA-SSD
lvcreate -n data2 -L 22T DATA-HDD

5.4创建lv并挂载

mkdir  /mnt/data1
mkdir  /mnt/data2


mkfs -t xfs /dev/DATA-SSD/data1
mount /dev/DATA-SSD/data1 /mnt/data1

mkfs -t xfs /dev/DATA-HDD/data2
mount /dev/DATA-HDD/data2 /mnt/data2

5.5 配置自动挂载

vim /etc/fstab

追加：

/dev/mapper/DATA--SSD-data1     /mnt/data1                   xfs     defaults        0 0
/dev/mapper/DATA--HDD-data2     /mnt/data2                   xfs     defaults        0 0

需要测试无问题，防止开机失败，执行：

mount -a
