Euler 21.10（华为欧拉）安装oracle19c-RAC

1. Euler 21.10安装oracle19c-RAC

1.1. 环境规划

1.1.1. 主机规划

|----------|---------------|-------|
| hostname | IP | 实例名 |
| hfdb90 | 192.168.40.90 | hfdb1 |
| hfdb91 | 192.168.40.90 | hfdb2 |

系统版本

BigCloud Enterprise Linux For Euler 21.10 (GNU/Linux 4.19.90-2107.6.0.0100.oe1.bclinux.x86_64 x86_64)

1.1.2. 磁盘规划

dggrid1：1g*3   -- 安装grid软件 ocr磁盘
dgsystem：8g=8g*1  -- 系统文件
dgrecovery：5g=5g*1  -- 闪回、归档目录
dgdata01：5g=5g*1  -- 数据文件目录

主机一：

主机二：

1.2. 主机配置（两台主机都要配置）

1.2.1. 修改主机名

主机名必须要和 hosts 文件中配置的名称要一致，否则后面安装会报错。

-- 主机一
hostnamectl set-hostname hfdb90 && bash 

-- 主机二
hostnamectl set-hostname hfdb91 && bash

1.2.2. host文件配置

vi /etc/hosts

cat >> /etc/hosts << EOF

192.168.40.90 hfdb90
192.168.40.91 hfdb91
10.10.10.90 hfdb90priv
10.10.10.91 hfdb91priv
192.168.40.92 hfdb90vip
192.168.40.93 hfdb91vip
192.168.40.94 hfdbscan
EOF

1.2.3. 修改环境变量

cat >> ~/.bash_profile << EOF
export LANG=en_US.UTF8

EOF

-- 使生效
source ~/.bash_profile

1.2.4. 创建用户和组

/usr/sbin/groupadd -g 60001 oinstall
/usr/sbin/groupadd -g 60002 dba
/usr/sbin/groupadd -g 60003 oper
/usr/sbin/groupadd -g 60004 backupdba
/usr/sbin/groupadd -g 60005 dgdba
/usr/sbin/groupadd -g 60006 kmdba
/usr/sbin/groupadd -g 60007 asmdba
/usr/sbin/groupadd -g 60008 asmoper
/usr/sbin/groupadd -g 60009 asmadmin
/usr/sbin/useradd -u 61001 -g oinstall -G asmadmin,asmdba,dba,asmoper,oper grid
/usr/sbin/useradd -u 61002 -g oinstall -G dba,backupdba,dgdba,kmdba,asmadmin,asmdba,oper oracle
echo "oracle" | passwd --stdin grid
echo "oracle" | passwd --stdin oracle

1.2.5. 创建目录

mkdir -p /oracle/app/grid
mkdir -p /oracle/app/19c/grid
chown -R grid:oinstall /oracle
mkdir -p /oracle/app/oraInventory
chown -R grid:oinstall /oracle/app/oraInventory
mkdir -p /oracle/app/oracle/product/19c/db_1
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle
chown -R grid:oinstall /backup
chmod -R 775 /backup

1.2.6. 配置yum源

mount /dev/cdrom /mnt
cd /etc/yum.repos.d
mkdir bk
mv *.repo bk/ 
echo "[EL]" >> /etc/yum.repos.d/hefei.repo 
echo "name =Linux 7.x DVD" >> /etc/yum.repos.d/hefei.repo 
echo "baseurl=file:///mnt" >> /etc/yum.repos.d/hefei.repo 
echo "gpgcheck=0" >> /etc/yum.repos.d/hefei.repo 
echo "enabled=1" >> /etc/yum.repos.d/hefei.repo 

cat /etc/yum.repos.d/itpux.repo 
[root@hfcwdb66 yum.repos.d]# yum list |more

1.2.8. 设置启动级别（可选）

systemctl set-default multi-user.target

1.3. 修改系统相关参数（两台主机都要配置）

1.3.1. 修改资源限制参数

cat >> /etc/security/limits.conf << EOF
#ORACLE SETTING
grid soft nproc 16384 
grid hard nproc 16384
grid soft nofile 65536
grid hard nofile 65536
grid soft stack 32768
grid hard stack 32768
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 65536
oracle hard nofile 65536
oracle soft stack 32768
oracle hard stack 32768
#oracle hard memlock 2000000
#oracle soft memlock 2000000
EOF

-- 生效
ulimit -a

1.3.2. 控制给用户分配的资源

echo "session required pam_limits.so" >> /etc/pam.d/login

cat /etc/pam.d/login

1.3.3. 修改进程限制数

#Amend the "/etc/security/limits.d/90-nproc.conf" file as described below. See MOS Note [ID 1487773.1]

echo "* - nproc 16384" > /etc/security/limits.d/90-nproc.conf

1.3.4. 修改内核参数

cat >> /etc/sysctl.conf << EOF
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmax = 2684354560
kernel.shmall = 655360
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
vm.nr_hugepages = 1200
net.ipv4.ip_local_port_range = 9000 65500
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
net.ipv4.ip_forward=1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
kernel.panic_on_oops = 1
vm.swappiness=5
vm.min_free_kbytes=204800
EOF

-- 生效
sysctl -p

配置参考：

kernel.shmmni = 4096

kernel.shmmax =物理内存0.8 102410241024*1024

kernel.shmall = shmmax/shmmni

1.3.5. 关闭透明页，开大内存页面要关闭

cat /sys/kernel/mm/transparent_hugepage/defrag
[always] madvise never
cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
这个状态说明是启用的

cat >> /etc/rc.d/rc.local << EOF
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
EOF

chmod +x /etc/rc.d/rc.local

1.3.6. 禁用NUMA

关闭NUMA=OFF
/etc/default/grub:
sed -ie 's/rhgb quiet/rhgb quiet numa=off/g' /etc/default/grub
cat /etc/default/grub
然后执行：
grub2-mkconfig -o /etc/grub2.cfg
用这个命令执行看下是不是一个cpu可以识别到所有的内存
numactl --show

1.3.7. 修改时区

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
hwclock

1.3.8. 配置安全

echo "SELINUX=disabled" > /etc/selinux/config
echo "#SELINUXTYPE=targeted " >> /etc/selinux/config
cat /etc/selinux/config
setenforce 0

1.3.9. 关闭防火墙

systemctl status firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service

1.3.10. 设置内存的文件系统shm

共享内存段vi /etc/fstabnone /dev/shm tmpfs defaults,size=6144m 0 0mount -o remount /dev/shmecho "NOZEROCONF=yes" >> /etc/sysconfig/networkvi /etc/nsswitch.conf修改行hosts: files dns myhostname为hosts: files dns myhostname nis

sed -ie 's/files dns myhostname/files dns myhostname nis/g' /etc/nsswitch.conf
cat /etc/nsswitch.conf

1.3.11. 关闭校时

systemctl stop ntpd
systemctl disable ntpd
systemctl status ntpd

systemctl stop chronyd
systemctl disable chronyd
systemctl status chronyd
rm -rf /etc/chrony.conf

修改时间：

date -s '2025-01-07 20:00:00'

1.4. 环境变量设置

  else
   ulimit -u 16384 -n 65536
      fi
    umask 022

1.4.3. 配置ssh信任关系（在一台上面操作就可）

./sshUserSetup.sh -user grid  -hosts "hfdb90 hfdb91" -advanced -noPromptPassphrase

./sshUserSetup.sh -user oracle  -hosts "hfdb90 hfdb91" -advanced -noPromptPassphrase

测试：不用认证，返回时间就是配置成功正常。

[grid@hfdb90:/home/grid]$ssh hfdb91 date

[grid@hfdb91:/home/grid]$ssh hfdb90 date

1.5. ASM磁盘配置

1.5.1. 磁盘配置（一台主机操作即可）

[root@hfdb90 soft]# fdisk -l |grep 'Disk /dev'
Disk /dev/sdb: 1 GiB, 1073741824 bytes, 2097152 sectors

1.5.2. 配置规则（两台主机都要配置）

vi /etc/udev/rules.d/99-oracle-asmdevices.rules --两个主机都要做

/sbin/udevadm trigger --type=devices --action=change

ls -lsa /dev/asm*

ls -lsa /dev/sd* -权限确认

1.6. Grid集群安装

1.6.1. 上传安装软件

新建/soft 目录

LINUX.X64_193000_grid_home.zip -- grid 安装包

p35940989_190000_Linux-x86-64.zip --19.22 grid 补丁

p6880880_190000_Linux-x86-64.zip --Opatch 工具

su -grid
cd /oracle/app/19c/grid 

-- 解压
unzip -q /soft/LINUX.X64_193000_grid_home.zip 
-- root: export CVUQDISK_GRP=oinstall 
rpm -ivh /oracle/app/19c/grid/cv/rpm/cvuqdisk-1.0.10-1.rpm  -- 第一台上安装

-- 第二台上面安装
scp /oracle/app/19c/grid/cv/rpm/cvuqdisk-1.0.10-1.rpm hfdb91:/soft
rpm -ivh /oracle/app/19c/grid/cv/rpm/cvuqdisk-1.0.10-1.rpm

1.6.2. 解压补丁包

mkdir p35
cd p35
unzip -q /soft/p35940989_190000_Linux-x86-64.zip

-- 备份之前的Opatch
cd /oracle/app/19c/grid

mv OPatch/ OPatch.bak
su - grid -c "unzip -q -o /soft/p6880880_190000_Linux-x86-64.zip -d /oracle/app/19c/grid"

1.6.3. 安装vnc（vnc 中无法打开 Terminal 终端）

yum install vnc

启动vnc ：vncserver

在 vnc 中执行：

cd/oracle/app/19c/grid
./gridSetup.sh -applyRU /soft/p35/35940989/

安装grid软件，使用vnc打开grid用户终端，始终打不开，无法进行安装操作。

1.6.4. 使用 X display 安装

报错 1：ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.

解决 1：yum -y install xdpyinfo

报错 2：

[root@hfdb90 ~]#

解决 2：

拷贝一个 libnsl-2.17.so 文件，云盘中有（两个节点都要执行）

ln -s libnsl-2.17.so /usr/lib64/libnsl.so.1

ls -rtl /usr/lib64/libnsl*

报错：ERROR: The home is not clean. This home cannot be used since there was a failed OPatch execution in this home. Use a different home to proceed.

解决：cd /oracle/app/19c/grid/install

[root@hfdb90 install]# mv patch patch.bak

--报错：

[grid@hfdb90:/oracle/app/19c/grid]$./gridSetup.sh -applyPSU /soft/p35/35940989/

Applying the patch /soft/p35/35940989/...

OPatch command failed while applying the patch. For details look at the logs from /oracle/app/19c/grid/cfgtoollogs/opatchauto/.

解决：

chown -R grid:oinstall /soft

chmod -R 775 /soft

使用 grid 用户安装：

配置完成后，检查通过。

报错：

An internal error occurred within cluster verification framework

An error occurred in creating a TaskFactory object or in generating a task list

PRVG-0282 : failed to retrieve the operating system distribution ID

解决：

因Oracle本身不支持该操作系统故修改 /opt/app/grid/ghome/cv/admin/cvu_config ，在文件末尾添加CV_ASSUME_DISTID=RHEL7，以RHEL7为安装标准。

下面的错误可以忽略：
