$root@srv01 \~$ # multipath -v3 | grep 3600

$root@srv01 \~$ # mpathconf

4.3 配置 UDEV

$root@srv01 \~$ # cd /dev/mapper

$root@srv01 mapper$ # ll

注意：2个节点均执行，root用户

$root@srv01 \~$ # cd /dev/mapper

复制代码

for i in asm_*; do
  printf "%s %s\n" "$i" "$(udevadm info --query=all --name=/dev/mapper/"$i" | grep -i dm_uuid)" >>/dev/mapper/udev_info
done
while read -r line; do
  dm_uuid=$(echo "$line" | awk -F'=' '{print $2}')
  disk_name=$(echo "$line" | awk '{print $1}')
  echo "KERNEL==\"dm-*\",ENV{DM_UUID}==\"${dm_uuid}\",SYMLINK+=\"${disk_name}\",OWNER=\"grid\",GROUP=\"asmdba\",MODE=\"0660\"" >>/etc/udev/rules.d/99-oracle-asmdevices.rules
done < /dev/mapper/udev_info

udevadm control --reload-rules

udevadm trigger --type=devices

ll /dev/dm*

五、操作系统配置

5.1 操作系统

$root@srv01 \~$ # cat /etc/oracle-release

Oracle Linux Server release 9.7

5.2 内存

$root@srv01 \~$ # grep MemTotal /proc/meminfo | awk '{print $2}'

32398736

5.3 swap

$root@srv01 \~$ # free -h

$root@srv01 \~$ # grep SwapTotal /proc/meminfo | awk '{print $2}'

5.4 安装依赖包

yum install -y bc binutils compat-openssl11 elfutils-libelf fontconfig glibc glibc-devel glibc-headers ksh libaio libasan liblsan libX11 libXau libXi libXrender libXtst libxcrypt-compat libgcc libibverbs librdmacm libstdc++ libxcb libvirt-libs make policycoreutils policycoreutils-python-utils smartmontools sysstat

5.5 关闭防火墙

注意：root用户两个节点均操作

systemctl stop firewalld

systemctl disable firewalld

systemctl status firewalld

5.6 关闭linux安全

$root@srv01 \~$ # vi /etc/selinux/config

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

5.7 chrony配置

systemctl status chronyd

yum -y install chrony

vi /etc/chrony.conf

sources 命令显示 chronyd 正在访问的当前时间源的信息。

可以使用可选参数 -v 来包括详细信息。在这种情况下，会输出额外的标头行显示字段含义的信息。

$ chronyc sources

5.8 修改login

$root@srv01 \~$ # cp /etc/pam.d/login /etc/pam.d/login_bak

$root@srv01 \~$ # echo "session required pam_limits.so" >> /etc/pam.d/login

5.9 修改limits.conf

复制代码

cat <<EOF>> /etc/security/limits.conf
#ORACLE SETTING
grid  soft  nproc 16384
grid  hard  nproc 16384
grid  soft  nofile 1024
grid  hard  nofile 65536
grid  soft  stack 10240
grid  hard  stack 32768
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack  10240
oracle hard stack  32768
oracle hard memlock 3428352
oracle soft memlock 3428352
EOF

memlock计算的原则：物理内存的90%（单位是KB）

5.10 修改内核参数

复制代码

cat <<EOF>> /etc/sysctl.conf
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmax = 22548578304
kernel.shmall = 5637144576
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
EOF

kernel.shmmax参数：需要根据实际物理内存计算，此处按节点物理内存128GB计算；建议kernel.shmmax参数取值为节点物理内存的70%，单位为字节，

即12870%10241024 1024=96207267430.4（向上取整为96207267430）。

kernel.shmall参数：根据SGA/PAGE_SIZE计算。

kernel.sem参数：如果客户单个数据库需要支持的process数超过12000，请按照实际情况配置。

生效命令：/sbin/sysctl --system

5.11 停止avahi-daemon服务

systemctl disable avahi-daemon.socket

systemctl disable avahi-daemon.service

systemctl stop avahi-daemon.socket

添加NOZEROCONF=yes参数

vi /etc/sysconfig/network

NOZEROCONF=yes

5.12 /etc/profile配置

复制代码

cat >> /etc/profile << EOF
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
            ulimit -p 16384
              ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
      fi
    umask 022
fi
EOF

六、Grid集群软件安装

6.1 上传软件包

$root@srv01 \~$ # ll /opt

6.2 解压grid安装包

[root@srv01 ~]$ cp /opt/LINUX.X64_2326100_grid_home.zip /u01/app/23.26.1/grid

[root@srv01 ~]# chown -R grid:oinstall /u01/app/23.26.1/grid
[root@srv01 ~]# chmod -R 775 /u01/app/23.26.1/grid
[root@srv01 ~]# su - grid
[grid@srv01 ~]$ cd $ORACLE_HOME
[grid@srv01 grid]$ unzip LINUX.X64_2326100_grid_home.zip

6.3 安装cvuqdisk

root用户下2个节点都要操作

$root@srv01 \~$ # cd /u01/app/23.26.1/grid/cv/rpm

$root@srv01 rpm$ # ll

$root@srv01 rpm$ # export CVUQDISK_GRP=oinstall

$root@srv01 rpm$ # rpm -ivh cvuqdisk-1.0.10-1.rpm

6.4 互信配置

do
ssh -l grid -o StrictHostKeyChecking=no $h date;
done

#oracle用户等效性

复制代码

srv01
ssh-keygen -t rsa
ssh-keygen -t dsa
srv02
ssh-keygen -t rsa
ssh-keygen -t dsa

srv01
cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys
ssh oracle@srv02 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys
srv02
cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys
ssh oracle@srv01 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys

for h in srv01 srv01-priv srv02 srv02-priv;
do
ssh -l oracle -o StrictHostKeyChecking=no $h date;
done

6.5 GI配置预检查

在配置GRID前，使用grid用户执行runcluvf.sh脚本检查环境，修复不满足安装需求的项

su - grid

/u01/app/23.26.1/grid/runcluvfy.sh stage -pre crsinst -n srv01,srv02 -fixup -verbose

6.6 执行安装

复制代码

[grid@srv01 grid]$ export DISPLAY=192.168.2.23:0.0
