本文主要是介绍[2021-01-05]RAC 安装19.1OGG之配置ACFS，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
因为要安装RAC的ogg，这里先安装ACFS
RAC版本为19c
OGG版本为19.1
平台为VMware
操作系统为 Red Hat Enterprise Linux Server release 7.2
1、首先创建共享盘
2、分别添加到RAC的两个节点中
打开vmware虚拟机的vmx文件，如下（RAC的两个节点都要执行）：
添加如下几行
3、使用udev绑定
查看新添加的磁盘
--//使用udev绑定，命令如下：
for i in e;
do
echo "KERNEL==\"sd*\",ENV{DEVTYPE}==\"disk\",SUBSYSTEM==\"block\",PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d \$devnode\",RESULT==\"`/usr/lib/udev/scsi_id -g -u /dev/sd$i`\", RUN+=\"/bin/sh -c 'mknod /dev/asmdisk$i b \$major \$minor; chown grid:asmadmin /dev/asmdisk$i; chmod 0660 /dev/asmdisk$i'\""
done
绑定前记录/etc/udev/rules.d/99-oracle-asmdevices.rules 文件内容
[root@dm01 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c29646b3175cadf174105bf96e66", RUN+="/bin/sh -c 'mknod /dev/asmdiskb b $major $minor; chown grid:asmadmin /dev/asmdiskb; chmod 0660 /dev/asmdiskb'"
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c293fd50d60d996a53338f6815a2", RUN+="/bin/sh -c 'mknod /dev/asmdiskc b $major $minor; chown grid:asmadmin /dev/asmdiskc; chmod 0660 /dev/asmdiskc'"
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c299f93b7eeabbbcf10d45aca528", RUN+="/bin/sh -c 'mknod /dev/asmdiskd b $major $minor; chown grid:asmadmin /dev/asmdiskd; chmod 0660 /dev/asmdiskd'"
[root@dm01 ~]# 绑定(RAC的两个节点都要执行)，把得到记录追加到/etc/udev/rules.d/99-oracle-asmdevices.rules
[root@dm01 ~]# for i in e;
> do
> echo "KERNEL==\"sd*\",ENV{DEVTYPE}==\"disk\",SUBSYSTEM==\"block\",PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d \$devnode\",RESULT==\"`/usr/lib/udev/scsi_id -g -u /dev/sd$i`\", RUN+=\"/bin/sh -c 'mknod /dev/asmdisk$i b \$major \$minor; chown grid:asmadmin /dev/asmdisk$i; chmod 0660 /dev/asmdisk$i'\""
> done
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c2902e3b82180d7f85215bddab06", RUN+="/bin/sh -c 'mknod /dev/asmdiske b $major $minor; chown grid:asmadmin /dev/asmdiske; chmod 0660 /dev/asmdiske'"
[root@dm01 ~]# 绑定后查看
[root@dm01 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",RESULT=="36000c29646b3175cadf174105bf96e66", RUN+="/bin/sh -c 'mknod /dev/asmdiskb b $major $minor; chown grid:asmadmin /dev/asmdiskb; chmod 0660 /dev/asmdiskb'"

[root@dm01 ~]# 但是发现并没有生成期望的asmdiske
[root@dm01 dev]# cd /dev/
[root@dm01 dev]# ls -ltr asm*

[root@dm01 dev]# 重新加载udev
[root@dm01 dev]# /sbin/udevadm trigger --type=devices --action=change
[root@dm01 dev]# /sbin/udevadm control --reload
[root@dm01 dev]# ls -ltr asm*

[root@dm01 dev]# 还是看不到，重启节点之后还是不行，最后决定手动创建了（RAC的2个节点都执行）
[root@dm01 dev]# ls -ltr /dev/sd*

4、使用asmca创建磁盘组
首先要创建ASM磁盘组，然后在此基础上创建ASM卷，最后才能创建ACFS
首先创建磁盘组
4.1)选中Disk Groups，点击左下角的create
4.2）选项External，磁盘组名字为OGG，选择刚创建的/dev/asmdiske磁盘
4.3)点击OK，开始创建磁盘组
4.4)OGG磁盘组创建成功
4.5)使用crsctl命令检查crsctl stat res -t
5、使用asmca创建acfs
5.1）grid用户调用asmca(RAC的任意一个节点)
5.2) 选中Volumes
5.3) 输入volume名字，选择磁盘组OGG，大小给4G，点击OK
5.4）volumes创建成功
5.5)创建ACFS，选中ACFS File Systems，点击create
5.6) 两节点首先创建好/ogg目录，然后勾选自动运行配置命令，点击OK
[root@dm01 dev]# mkdir -p /ogg
[root@dm01 dev]# chown -R oracle:oinstall /ogg
遇到DBT-30145 You need to enter the root credentials in 'Settings' for ASMCA
把自动运行勾选去掉，先show command显示如下：
5.7）运行acfs_script.sh脚本
[grid@dm02 ~]$ /u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh
PRCN-2018 : Current user grid is not a privileged user
[grid@dm02 ~]$ su - root

[root@dm02 ~]# /u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh
ACFS file system /ogg is mounted on nodes dm01,dm02
[root@dm02 ~]# 5.8）查看acfs文件系统是否能够正常显示
