一 V M ware 共享磁盘划分
1. 1 添加硬盘 2 ， 2 GB
1. 2 添加硬盘 3 ， 2 GB
1. 3 添加硬盘 4 ， 2 GB
1. 4 添加硬盘 5 ， 40GB
1. 5 添加硬盘 6 ， 60GB
1. 6 修改 O EL7.8 虚拟机配置文件
在配置文件中添加下列两个选项，如下：
disk.locking = "FALSE" disk.EnableUUID = "TRUE"
注：配置文件路径和名称需要根据实际环境进行编辑，编辑修改之前需要将虚拟机关闭。
二 V Mware 共享磁盘权限绑定
2 . 1 通过 U UID 方式绑定
2.1.1 检查共享盘 U UID
手动获取 5 块共享磁盘的 U UID ，如下：
for i in b c d e f; do /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i Done 36000c29ffcc093850385a88ec91ed936 36000c293cf9a163d34ce276eee6cac11 36000c29a5c8b104a1d740e6308e8c726 36000c2985c7484f3bb5b9284af895658 36000c294503175eb177879df26866b37
2.1.2 新建 60-raw.rules 文件
使用 60-raw.rules 文件配置共享磁盘权限，如下：
# vi /etc/udev/rules.d/60-raw.rules KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29ffcc093850385a88ec91ed936", SYMLINK+="ocr1",OWNER="grid", GROUP="oinstall",MODE="0660" KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c293cf9a163d34ce276eee6cac11", SYMLINK+="ocr2",OWNER="grid", GROUP="oinstall",MODE="0660" KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29a5c8b104a1d740e6308e8c726", SYMLINK+="ocr3",OWNER="grid", GROUP="oinstall",MODE="0660" KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c2985c7484f3bb5b9284af895658", SYMLINK+="mgmt",OWNER="grid", GROUP="oinstall",MODE="0660" KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c294503175eb177879df26866b37", SYMLINK+="data",OWNER="grid", GROUP="oinstall",MODE="0660"
2.1.3 执行 ud evadm 使权限生效
# udevadm trigger --action=add
2.1.4 检查共享磁盘权限绑定情况
# ls -rtl /dev/sd* brw-rw---- 1 root disk 8, 0 Apr 5 13:30 /dev/sda brw-rw---- 1 root disk 8, 2 Apr 5 13:30 /dev/sda2 brw-rw---- 1 root disk 8, 1 Apr 5 13:30 /dev/sda1 brw-rw---- 1 grid oinstall 8, 80 Apr 5 13:37 /dev/sdf brw-rw---- 1 grid oinstall 8, 64 Apr 5 13:37 /dev/sde brw-rw---- 1 grid oinstall 8, 32 Apr 5 13:37 /dev/sdc brw-rw---- 1 grid oinstall 8, 48 Apr 5 13:37 /dev/sdd brw-rw---- 1 grid oinstall 8, 16 Apr 5 13:37 /dev/sdb
2 . 2 通过 ASMLIB 方式绑定
2.2.1 安装 oracle asm 依赖包
# rpm -ivh kmod-oracleasm-2.0.8-27.0.1.el7.x86_64.rpm # rpm -ivh oracleasmlib-2.0.12-1.el7.x86_64.rpm # rpm -ivh oracleasm-support-2.1.11-2.el7.x86_64.rpm
注意： oracleasmlib 依赖包需要单独下载，下载地址参考： https://access.redhat.com/solutions/315643 ，其他依赖包可以在 O EL7.8 镜像中找到。
2.2.2 初始化 oracle asm
# oracleasm init Creating /dev/oracleasm mount point: /dev/oracleasm Loading module "oracleasm": oracleasm Configuring "oracleasm" to use device physical block size Mounting ASMlib driver filesystem: /dev/oracleasm
2.2.3 配置 ASM library driver
# oracleasm configure -e -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: grid
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [y]:
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
2.2.4 启动 oracle asm 服务
# systemctl start oracleasm # systemctl status oracleasm
2.2.5 清除共享盘盘头信息
# dd if=/dev/zero of=/dev/sdb bs=1024 count=1024 # dd if=/dev/zero of=/dev/sdc bs=1024 count=1024 # dd if=/dev/zero of=/dev/sdd bs=1024 count=1024 # dd if=/dev/zero of=/dev/sde bs=1024 count=1024 # dd if=/dev/zero of=/dev/sdf bs=1024 count=1024
2.2.6 创建共享盘磁盘分区
手动分别为 5 块共享磁盘创建磁盘一个分区，如下：
# fdisk /dev/sdb # fdisk /dev/sdc # fdisk /dev/sdd # fdisk /dev/sde # fdisk /dev/sdf
5 块共享磁盘磁盘分区创建情况，如下：
# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdf 8:80 0 60G 0 disk └─sdf1 8:81 0 60G 0 part sdd 8:48 0 2G 0 disk └─sdd1 8:49 0 2G 0 part sdb 8:16 0 2G 0 disk └─sdb1 8:17 0 2G 0 part sde 8:64 0 40G 0 disk └─sde1 8:65 0 40G 0 part sdc 8:32 0 2G 0 disk └─sdc1 8:33 0 2G 0 part
2.2.7 手动创建 ASMDISK
# oracleasm createdisk ASMDISK1 /dev/sdb1 # oracleasm createdisk ASMDISK2 /dev/sdc1 # oracleasm createdisk ASMDISK3 /dev/sdd1 # oracleasm createdisk ASMDISK4 /dev/sde1 # oracleasm createdisk ASMDISK5 /dev/sdf1
2.2.8 检查 ASMDISK 权限
# oracleasm scandisks # oracleasm listdisks ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5 # ls -l /dev/oracleasm/disks/ASMDISK* brw-rw---- 1 grid oinstall 8, 17 Apr 5 14:46 /dev/oracleasm/disks/ASMDISK1 brw-rw---- 1 grid oinstall 8, 33 Apr 5 14:46 /dev/oracleasm/disks/ASMDISK2 brw-rw---- 1 grid oinstall 8, 49 Apr 5 14:46 /dev/oracleasm/disks/ASMDISK3 brw-rw---- 1 grid oinstall 8, 65 Apr 5 14:46 /dev/oracleasm/disks/ASMDISK4 brw-rw---- 1 grid oinstall 8, 81 Apr 5 14:46 /dev/oracleasm/disks/ASMDISK5
三 V M ware 集群网络划分
