Oracle Linux 9.7 + VMware 搭建 Oracle 26ai RAC 实战指南

一、安装规划

1.1 软件规划

序号 软件 版本
1 虚拟化软件 VMware®Workstation 16 Pro 16.2.4 build-20089737
2 操作系统软件 OracleLinux-R9-U7-Server-x86_64-dvd.iso,要求9.2以上
3 Oracle软件 LINUX.X64_2326100_db_home.zip
4 GI软件 LINUX.X64_2326100_grid_home.zip

1.1.1 软件下载

1.1.1.1 操作系统下载

可以利用sha256sum检验软件的完整性。

1.1.2 操作系统认证

26ai操作系统认证.png

因此安装Oracle26ai RAC,选择Oracle Linux 9操作系统,要求在9.2版本以上,这点请注意。

1.2 虚拟机规划

虚拟机规划.png

Oracle 数据库安装至少需要 1 GB 内存。建议使用 2 GB 内存。Oracle Grid Infrastructure 安装至少需要 8 GB 内存,我们这里给两台虚拟机各4颗CPU,16G内存,磁盘100G。

CPU 内存 磁盘空间 网卡 操作系统版本
4C 16G 100G 两个网卡,一块Public IP、一块Private IP Oracle Linux Server release 9.7
4C 16G 100G 两个网卡,一块Public IP、一块Private IP Oracle Linux Server release 9.7

1.3 网络规划

从Oracle 11g开始,一共至少7个IP地址,2块网卡,其中public、vip和scan都在同一个网段,private在另一个网段,主机名不要包含下横线,如:RAC_01是不允许的;通过执行ifconfig -a检查2个节点的网卡名称必须一致。另外,在安装之前,公网、私网共4个IP可以ping通,其它3个不能ping通才是正常的。从18c开始,生产环境scan建议至少3个。

节点名称 Public IP(NAT) Private IP(HOST) Virtual IP SCAN 名称 SCAN IP
rac1 192.168.18.5 18.18.18.5 192.168.18.7 rac-scan 192.168.18.9
rac2 192.168.18.6 18.18.18.6 192.168.18.8

1.4 操作系统规划

Table 1-3 Server Configuration Checklist for Oracle AI Database

Check Task
Disk space allocated to the /tmp directory At least 1 GB of space in the /tmp directory.
Swap space allocation relative to RAM (Oracle AI Database) Between 1 GB and 2 GB: 1.5 times the size of the RAM Between 2 GB and 16 GB: Equal to the size of the RAM More than 16 GB: 16 GB Note: If you enable HugePages for your Linux servers, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.
Swap space allocation relative to RAM (Oracle Restart) Between 8 GB and 16 GB: Equal to the size of the RAM More than 16 GB: 16 GB Note: If you enable HugePages for your Linux servers, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.
Oracle Inventory (oraInventory) and OINSTALL Group Requirements For upgrades, the installer detects an existing oraInventory directory from the /etc/oraInst.loc file, and uses the existing oraInventory.For new installs, if you have not configured an oraInventory directory, then you can specify the oraInventory directory during the software installation and Oracle Universal Installer will set up the software directories for you. The Oracle inventory is one directory level up from the Oracle base for the Oracle software installation and designates the installation owner’s primary group as the Oracle inventory group. Ensure that the oraInventory path that you specify is in compliance with the Oracle Optimal Flexible Architecture recommendations.The Oracle Inventory directory is the central inventory of Oracle software installed on your system. Users who have the Oracle Inventory group as their primary group are granted the OINSTALL privilege to write to the central inventory.The OINSTALL group must be the primary group of all Oracle software installation owners on the server. It should be writable by any Oracle installation owner.
Groups and users Oracle recommends that you create groups and user accounts required for your security plans before starting installation. Installation owners have resource limits settings and other requirements. Group and user names must use only ASCII characters.You can use the Preinstallation RPM to automatically create the oracle user and the oraInventory (oinstall) and OSDBA (dba) groups for you.
Mount point paths for the software binaries Oracle recommends that you create an Optimal Flexible Architecture configuration as described in the appendix “Optimal Flexible Architecture” in Oracle AI Database Installation Guide for your platform.
Ensure that the Oracle home (the Oracle home path you select for Oracle AI Database) uses only ASCII characters The ASCII character restriction includes installation owner user names, which are used as a default for some home paths, as well as other directory names you may select for paths.
Unset Oracle software environment variables If you have an existing Oracle software installation, and you are using the same user to install this installation, then unset the following environment variables: $ORACLE_HOME,$ORA_NLS10, and $TNS_ADMIN.If you have set $ORA_CRS_HOME as an environment variable, then unset it before starting an installation or upgrade. Do not use $ORA_CRS_HOME as a user environment variable, except as directed by Oracle Support.
Set locale (if needed) Specify the language and the territory, or locale, in which you want to use Oracle components. A locale is a linguistic and cultural environment in which a system or program is running. NLS (National Language Support) parameters determine the locale-specific behavior on both servers and clients. The locale setting of a component determines the language of the user interface of the component, and the globalization behavior, such as date and number formatting.
Check Shared Memory File System Mount By default, your operating system includes an entry in /etc/fstab to mount /dev/shm. However, if your Configuration Verification Utility (CVU) or installer checks fail, ensure that the /dev/shm mount area is of type tmpfs and is mounted with the following options:rw and exec permissions set on itWithout noexec or nosuid set on itNote: These options may not be listed as they are usually set as the default permissions by your operating system.
Symlinks Oracle home or Oracle base cannot be symlinks, nor can any of their parent directories, all the way to up to the root directory.

1.4.1 操作系统目录

由于我们是测试这里把所有空间都给到/目录,生产环境我们可以划分成/目录100G,/boot目录1G,swap目录16G,/u01软件目录300G,/tmp目录20G,/home目录50G,

分区 大小
/boot 1G
/ 83G
swap 16.1G

1.4.2 软件包

Table 4-1 x86-64 Oracle Linux 9 Minimum Operating System Requirements

Item Requirements
SSH Requirement Ensure that OpenSSH is installed on your servers. OpenSSH is the required SSH software.
Oracle Linux 9 Minimum supported versions:Oracle Linux 9.2 with the Unbreakable Enterprise Kernel 7: 5.15.0-201.135.6.el9uek.x86_64 or laterOracle Linux 9.2 with the Red Hat Compatible Kernel: 5.14.0-284.30.1.el9_2.x86_64 or laterNote: Oracle recommends that you update Oracle Linux to the latest available version and release level.
Packages for Oracle Linux 9 Install the latest released versions of the following packages:Subscribe to the Oracle Linux 9 channel on the Unbreakable Linux Network, or configure a yum repository from the Oracle Linux yum server website, and then install the Oracle AI Database Preinstallation RPM, oracle-ai-database-preinstall-26ai. The Oracle AI Database Preinstallation RPM, oracle-ai-database-preinstall-26ai, automatically installs all required packages listed in the table below, their dependencies for Oracle Grid Infrastructure and Oracle AI Database installations, and also performs other system configuration. If you install the Oracle AI Database Preinstallation RPM, oracle-ai-database-preinstall-26ai, then you do not have to install these packages, as the Oracle AI Database Preinstallation RPM automatically installs them. 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
Optional Packages for Oracle Linux 9 Based on your requirement, install the latest released versions of the following packages: ipmiutil (for Intelligent Platform Management Interface) libnsl2 (for Oracle Database Client only) libnsl2-devel (for Oracle Database Client only) net-tools (for Oracle RAC and Oracle Clusterware) nfs-utils (for Oracle ACFS)

1.5 共享存储规划

Table 1-6 Oracle Grid Infrastructure Storage Configuration Checks

Check Task
Minimum disk space (local or shared) for Oracle Grid Infrastructure Software At least 12 GB of space for the Oracle Grid Infrastructure for a cluster home (Grid home). Oracle recommends that you allocate 100 GB to allow additional space for patches. At least 10 GB for Oracle AI Database Enterprise Edition.Allocate additional storage space as per your cluster configuration, as described in Oracle Clusterware Storage Space Requirements.
Select Oracle ASM Storage Options During installation, based on the cluster configuration, you are asked to provide Oracle ASM storage paths for the Oracle Clusterware files. These path locations must be writable by the Oracle Grid Infrastructure installation owner (Grid user). These locations must be shared across all nodes of the cluster on Oracle ASM because the files in the Oracle ASM disk group created during installation must be available to all cluster member nodes.For Oracle Grid Infrastructure deployment to manage Oracle RAC databases, shared storage, either Oracle ASM or shared file system, is locally mounted on each of the cluster nodes.Voting files are files that Oracle Clusterware uses to verify cluster node membership and status. Oracle Cluster Registry files (OCR) contain cluster and database configuration information for Oracle Clusterware.

Table 8-1 Minimum Available Space Requirements for Oracle Grid Infrastructure Deployment to Manage Oracle RAC Databases

Redundancy Level DATA Disk Group Oracle Fleet Patching and Provisioning Total Storage
External 1 GB 1 GB 2 GB
Normal 2 GB 2 GB 4 GB
High/Flex/Extended 3 GB 3 GB 6 GB
  • Oracle recommends that you use a separate disk group, other than DATA, for Oracle Clusterware backup files.
  • The initial sizing for the Oracle Grid Infrastructure deployment to manage Oracle RAC databases is for up to four nodes. You must add additional storage space to the disk group containing Oracle Clusterware backup files for each new node added to the cluster.
  • By default, all new Oracle Grid Infrastructure deployments to manage Oracle RAC databases are configured with Oracle Fleet Patching and Provisioning for patching that cluster only. This deployment requires a minimal ACFS file system that is automatically configured.

根据要求,采用的磁盘组策略如下:

ASM磁盘名称 磁盘组名称 冗余方式 大小 用途 备注
/dev/asm-ocrvote OCRVOTE External 3*5G OCR+VOTINGDISK 建议用3块
/dev/asm-data DATA External 2*20G 存储数据库数据文件

4.3.4 调整network

当使用Oracle集群的时候,Zero Configuration Network一样可能会导致节点间的通信问题,所以也应该停掉 Without zeroconf, a network administrator must set up network services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually. 在使用平常的网络设置方式的情况下是可以停掉Zero Conf的 两个节点执行 echo "NOZEROCONF=yes" >>/etc/sysconfig/network && cat /etc/sysconfig/network [root@rac1 ~]# echo "NOZEROCONF=yes" >>/etc/sysconfig/network && cat /etc/sysconfig/network # Created by anaconda NOZEROCONF=yes [root@rac1 ~]# [root@rac2 ~]# echo "NOZEROCONF=yes" >>/etc/sysconfig/network && cat /etc/sysconfig/network # Created by anaconda NOZEROCONF=yes [root@rac2 ~]#

这里实验环境,选择不使用NTP和chrony,这样Oracle会自动使用自己的ctss服务

4.16.2 使用ntp

1)修改所有节点的/etc/ntp.conf 【命令】vi /etc/ntp.conf 【内容】 restrict 192.168.17.5 nomodify notrap nopeer noquery //当前节点IP地址 restrict 192.168.17.2 mask 255.255.255.0 nomodify notrap //集群所在网段的网关(Gateway),子网掩码(Genmask) 2)选择一个主节点,修改其/etc/ntp.conf 【命令】vi /etc/ntp.conf 【内容】在server部分添加一下部分,并注释掉server 0 ~ n server 127.127.1.0 Fudge 127.127.1.0 stratum 10 3)主节点以外,继续修改/etc/ntp.conf 【命令】vi /etc/ntp.conf 【内容】在server部分添加如下语句,将server指向主节点。 server 192.168.17.5 Fudge 192.168.17.5 stratum 10 节点1 echo systemctl status ntpd systemctl stop ntpd systemctl stop chronyd systemctl disable chronyd sed -i 's/OPTIONS="-g"/OPTIONS="-g -x"/' /etc/sysconfig/ntpd vim /etc/ntp.conf 注释server sed '/^server/s/^/#/' /etc/ntp.conf -i server 127.127.1.0 Fudge 127.127.1.0 stratum 10 # Hosts on local network are less restricted. restrict 192.168.17.0 mask 255.255.255.0 nomodify notrap 把网段改为 192.168.17.0,取消注释 # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). #server 0.rhel.pool.ntp.org iburst #server 1.rhel.pool.ntp.org iburst #server 2.rhel.pool.ntp.org iburst #server 3.rhel.pool.ntp.org iburst server 127.127.1.0 Fudge 127.127.1.0 stratum 10 #broadcast 192.168.1.255 autokey # broadcast server #broadcastclient # broadcast client #broadcast 224.0.1.1 autokey # multicast server #multicastclient 224.0.1.1 # multicast client #manycastserver 239.255.254.254 # manycast server #manycastclient 239.255.254.254 autokey # manycast client # Enable public key cryptography. #crypto includefile /etc/ntp/crypto/pw # Key file containing the keys and key identifiers used when operating # with symmetric key cryptography. keys /etc/ntp/keys --- 把网段改为 192.168.17.0 systemctl start ntpd systemctl enable ntpd echo 节点2 echo systemctl stop ntpd systemctl stop chronyd systemctl disable chronyd sed -i 's/OPTIONS="-g"/OPTIONS="-g -x"/' /etc/sysconfig/ntpd sed -i 's/^server/#server/g' /etc/ntp.conf sed -i '$a server 192.168.17.141 iburst' /etc/ntp.conf systemctl start ntpd systemctl enable ntpd echo 检查ntp配置文件/etc/sysconfig/ntpd,也已经从默认值OPTIONS="-g"修改成OPTIONS="-x -g",但是在使用命令$ cluvfy comp clocksync -n all –verbose检查时为什么会失败呢? 通过MOS文档《Linux:CVU NTP Prerequisite check fails with PRVF-7590, PRVG-1024 and PRVF-5415 (Doc ID2126223.1)》分析可以看出:If var/run/ntpd.pid does not existon the server, the CVU command fails. This is due to unpublished bug 19427746 which has been fixed in Oracle 12.2.(意思是:如果服务器上不存在/var/run/ntpd.pid,则CVU命令失败。这是由于未发布的错误BUG 19427746,该错误已在Oracle 12.2中修复。)

IF THE SETUP IS CORRECTLY SETUP, THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR PASSWORDS. If you see any output other than date or are prompted for the password, ssh is not setup correctly and you will need to resolve the issue and set up ssh again. The possible causes for failure could be: 1. The server settings in /etc/ssh/sshd_config file do not allow ssh for user grid. 2. The server may have disabled public key based authentication. 3. The client public key on the server may be outdated. 4. ~grid or ~grid/.ssh on the remote host may not be owned by grid. 5. User may not have passed -shared option for shared remote users or may be passing the -shared option for non-shared remote users. 6. If there is output in addition to the date, but no password is asked, it may be a security alert shown as part of company policy. Append the additional text to the <OMS HOME>/sysman/prov/resources/ignoreMessages.txt file. ------------------------------------------------------------------------ --rac1:-- Running /usr/bin/ssh -x -l grid rac1 date to verify SSH connectivity has been setup from local host to rac1.

创建ASM磁盘3.png

七、安装Oracle软件

7.1 修改软件包权限

mv LINUX.X64_2326100_db_home.zip /soft cd /soft chown oracle:oinstall LINUX.X64_2326100_db_home.zip [root@rac1 ~]# mv LINUX.X64_2326100_db_home.zip /soft [root@rac1 ~]# cd /soft [root@rac1 soft]# chown oracle:oinstall LINUX.X64_2326100_db_home.zip [root@rac1 soft]#

7.2 解压缩到oracle_home

su - oracle unzip -q /soft/LINUX.X64_2326100_db_home.zip -d $ORACLE_HOME [root@rac1 soft]# su - oracle Last login: Thu Oct 23 11:59:22 CST 2025 on pts/0 [oracle@rac1:/home/oracle]$ unzip -q /soft/LINUX.X64_193000_db_home.zip -d $ORACLE_HOME [oracle@rac1:/home/oracle]$

7.3 升级opatch版本(可选)

这里不需要升级

[oracle@rac1:/u01/app/oracle/product/23.0.0/dbhome_1/OPatchbak]$ ./opatch version
OPatch Version: 12.2.0.1.17

OPatch succeeded.
[oracle@rac1:/u01/app/oracle/product/23.0.0/dbhome_1]$ mv OPatch/ OPatchbak
[oracle@rac1:/u01/app/oracle/product/23.0.0/dbhome_1]$ unzip /u01/sw/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME

[oracle@rac1:/u01/app/oracle/product/23.0.0/dbhome_1/OPatchbak]$ ./opatch version
OPatch Version: 12.2.0.1.17

OPatch succeeded.

After the script is executed, the user can use SSH to run commands on the remote hosts or copy files between this host rac1 and the remote hosts without being prompted for passwords or confirmations. NOTE 1: As part of the setup procedure, this script will use ssh and scp to copy files between the local host and the remote hosts. Since the script does not store passwords, you may be prompted for the passwords during the execution of the script whenever ssh or scp is invoked.

IF THE SETUP IS CORRECTLY SETUP, THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR PASSWORDS. If you see any output other than date or are prompted for the password, ssh is not setup correctly and you will need to resolve the issue and set up ssh again. The possible causes for failure could be: 1. The server settings in /etc/ssh/sshd_config file do not allow ssh for user oracle. 2. The server may have disabled public key based authentication. 3. The client public key on the server may be outdated. 4. ~oracle or ~oracle/.ssh on the remote host may not be owned by oracle. 5. User may not have passed -shared option for shared remote users or may be passing the -shared option for non-shared remote users. 6. If there is output in addition to the date, but no password is asked, it may be a security alert shown as part of company policy. Append the additional text to the <OMS HOME>/sysman/prov/resources/ignoreMessages.txt file. ------------------------------------------------------------------------ --rac1:-- Running /usr/bin/ssh -x -l oracle rac1 date to verify SSH connectivity has been setup from local host to rac1.
