Oracle 19C RAC 静默(silent)安装on RHEL7.x 一、安装准备
1.1.RHEL版本及IP规划
1.1.1.OS版本信息
[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.6 (Maipo)
[root@localhost ~]# uname -r
3.10.0-957.el7.x86_64
1.1.2.IP规划
| 主机 | Public | VIP | Scanip | Private |
|---|---|---|---|---|
| ydb01 | 192.168.10.91 | 192.168.10.93 | 192.168.10.95 | 172.16.16.91/92 |
| ydb02 | 192.168.10.92 | 192.168.10.94 | 192.168.10.95 | 172.16.16.93/94 |
2.硬件检查
1.2.1.硬盘空间检查
/tmp目录大小至少：1GB
安装Grid Infrastracture所需空间：12GB
安装Oracle Database所需空间：7.3GB
此外安装过程中分析、收集、跟踪文件所需空间：10GB
建议总共至少100GB（此处不包含ASM或NFS的空间需求）
# df -h
1.2.2.内存检查
内存大小：至少8GB
Swap大小：
当内存为4GB-16GB时，Swap需要大于等于系统内存。
当内存大于16GB时，Swap等于16GB即可。
# grep MemTotal /proc/meminfo
# grep SwapTotal /proc/meminfo
1.3.创建用户和组
创建用户和组,用户uid和组gid所有节点需要相同。
1.3.1.添加用户和用户组

1.6.防火墙与Selinux
1.6.1.关闭selinux
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
1.6.2.关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
1.7.设置OS内核参数
vi /etc/sysctl.conf
#for oracle 19c rac @Yong @20190509
####fs setting
fs.aio-max-nr = 4194304

1.8.安装必要的rpm包
1.8.1.配置本地yum源
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 268G 4.3G 264G 2% /
devtmpfs 7.9G 0 7.9G 0% /dev
tmpfs 7.9G 0 7.9G 0% /dev/shm
tmpfs 7.9G 13M 7.9G 1% /run
tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup
tmpfs 1.6G 56K 1.6G 1% /run/user/0
/dev/sr0 4.2G 4.2G 0 100% /run/media/root/RHEL-7.6 Server.x86_64
vi /etc/yum.repos.d/rhel-iso.repo
[ISO-DVD]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=file:///run/media/root/RHEL-7.6\ Server.x86_64/
enabled=1
gpgcheck=0
如果没有光驱可以将RHEL的安装ISO文件上传到服务器上，然后通过下列命令挂载ISO
mkdir /mnt/rhel76iso
mount -o loop -t iso9660 /root/rhel-server-7.6-x86_64-dvd.iso /mnt/rhel76iso
vi /etc/yum.repos.d/rhel-iso.repo
[ISO-DVD]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=file:///mnt/rhel76iso
enabled=1
gpgcheck=0
1.8.2.安装rpm包
yum install bc gcc gcc-c++ binutils make gdb cmake glibc ksh \
elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc-devel \
libaio libaio-devel libXrender libXrender-devel libX11 libXau sysstat \
libXi libXtst libgcc librdmacm-devel libstdc++ libstdc++-devel libxcb \
net-tools nfs-utils compat-libcap1 compat-libstdc++ smartmontools targetcli \
python python-configshell python-rtslib python-six unixODBC unixODBC-devel
由于RHEL7 缺失compat-libstdc+±33包，需要单独下载安装
wget ftp://ftp.pbone.net/mirror/ftp5.gwdg.de/pub/opensuse/repositories/home:/matthewdva:/build:/RedHat:/RHEL-7/complete/x86_64/compat-libstdc++-33-3.2.3-71.el7.x86_64.rpm
yum localinstall compat-libstdc++-33-3.2.3-71.el7.x86_64.rpm
1.9. ASM磁盘初始化
如果不部署mgmtdb,3块5G的磁盘用于OCR和voting disk即可，如果部署mgmtdb
mgmtdb独立磁盘的情况下，normal冗余需要53G+存储，external冗余需要27G+存储
mgmtdb与ocr及vote disk在同一磁盘组的情况下，normal的磁盘需要56G+存储
本次安装不部署mgmtdb，规划四块存储，3块5G和1块50G,采用udev映射
1.9.1.初始化磁盘
[root@ydb01 ~]# echo -e "n\np\n1\n\n\nw" | fdisk /dev/sdb
[root@ydb01 ~]# echo -e "n\np\n1\n\n\nw" | fdisk /dev/sdc
[root@ydb01 ~]# echo -e "n\np\n1\n\n\nw" | fdisk /dev/sdd
[root@ydb01 ~]# echo -e "n\np\n1\n\n\nw" | fdisk /dev/sde
1.9.2. udev映射

1.10.其他优化
1.10.1.关闭THP及NUMA
vi /etc/default/grub
在GRUB_CMDLINE_LINUX添加下列选项，用于关闭THP和NUMA
transparent_hugepage=never numa=off
编译并重启主机
On BIOS: ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
On UEFI: ~]# grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg
1.10.2.NTP配置
如果使用CTSS来同步集群间的时间则可以关闭时间同步
systemctl stop chronyd
systemctl disable chronyd
mv /etc/chrony.conf /etc/chrony.conf.bak
1.10.3.禁用avahi
systemctl stop avahi-dnsconfd
systemctl stop avahi-daemon
systemctl disable avahi-dnsconfd
systemctl disable avahi-daemon
2.1.解压软件
[grid@ydb01 ~]$ cd /opt/software/

Linux平台 Oracle 19c RAC安装
一、 实施前期准备工作
二、 安装前期准备工作
- 2.1 各节点系统时间校对
- 2.2 各节点关闭防火墙和SELinux
- 2.3 各节点检查系统依赖包安装情况
- 2.4 各节点配置/etc/hosts
- 2.5 各节点创建需要的用户和组
- 2.6 各节点创建安装目录
- 2.7 各节点系统配置文件修改
- 2.8 各节点设置用户的环境变量
Linux平台 Oracle 19c RAC安装指导：
Part1： Linux平台 Oracle 19c RAC安装Part1：准备工作
Part2： Linux平台 Oracle 19c RAC安装Part2：GI配置
Part3： Linux平台 Oracle 19c RAC安装Part3：DB配置
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
一、实施前期准备工作1.1 服务器安装操作系统
配置完全相同的两台服务器，安装相同版本的Linux操作系统。留存系统光盘或者镜像文件。
我这里是OEL7.6，系统目录大小均一致。对应OEL7.6的系统镜像文件放在服务器上，供后面配置本地yum使用。
1.2 Oracle安装介质
Oracle 19.3 版本2个zip包(总大小6G+,注意空间)：
LINUX.X64_193000_grid_home.zip MD5:
LINUX.X64_193000_db_home.zip MD5:
这个自己去Oracle官网下载，然后只需要上传到节点1即可。
1.3 共享存储规划
从存储中划分出两台主机可以同时看到的共享LUN，3个1G的盘用作OCR和Voting Disk，其余分了3个12G的盘规划做用做数据盘和FRA。
注：19c安装GI时，可以选择是否配置GIMR，且默认不配置，我这里选择不配置，所以无需再给GIMR分配对应空间。
--OEL7使用udev需要给磁盘创建分区，这里我使用fdisk 将对应盘创建一个主分区，分区号为2（这里只是为了区分）:
sdb sdc sdd sde sdf sdg
sdb2 sdc2 sdd2 sde2 sdf2 sdg21G 1G 1G 12G 12G 12G
--OEL7中udev需绑定对应磁盘的分区for i in b c d e f g;doecho "KERNEL==\"sd?2\", SUBSYSTEM==\"block\", PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d /dev/\$parent\", RESULT==\"`/usr/lib/udev/scsi_id -g -u -d /dev/sd\$i`\", SYMLINK+=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"" done

lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-ocr3 -> sdd2我这次搭建的实验环境为了精简，没有再去模拟多路径的环境，如果想尽可能的模拟生产环境，可以参考之前18c的配置：
1.4 网络规范分配
公有网络 以及 私有网络。
公有网络：这里实验环境是enp0s3是public IP，enp0s8是ASM & Private IP，实际生产需根据实际情况调整规划，一般public是有OS层绑定（bonding），private是使用HAIP。
2.1 各节点系统时间校对
各节点系统时间校对:
--检验时间和时区确认正确date --关闭chrony服务，移除chrony配置文件（后续使用ctss）systemctl list-unit-files|grep chronyd
systemctl status chronyd
systemctl disable chronyd
systemctl stop chronyd
mv /etc/chrony.conf /etc/chrony.conf_bak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。
2.2 各节点关闭防火墙和SELinux
各节点关闭防火墙:
systemctl list-unit-files|grep firewalld
systemctl status firewalld
systemctl disable firewalld
systemctl stop firewalld各节点关闭SELinux:
getenforce
cat /etc/selinux/config手工修改/etc/selinux/config SELINUX=disabled，或使用下面命令：
sed -i '/^SELINUX=.*/ s//SELINUX=disabled/' /etc/selinux/configsetenforce 0最后核实各节点已经关闭SELinux即可。
2.3 各节点检查系统依赖包安装情况
yum install -y oracle-database-preinstall-18c-1.0-1.el7.x86_64在OEL7.6中还是oracle-database-preinstall-18c的名字，并没有对应19c的，但实际测试，在依赖包方面基本没区别。
如果选用的是其他Linux，比如常用的RHEL，那就需要yum安装官方文档要求的依赖包了。
2.4 各节点配置/etc/hosts
编辑/etc/hosts文件：
#public ip192.168.1.193 db193192.168.1.195 db195#virtual ip192.168.1.194 db193-vip192.168.1.196 db195-vip#scan ip192.168.1.197 db19c-scan#private ip10.10.1.193 db193-priv10.10.1.195 db195-priv修改主机名(建议由SA调整)：
--例如：修改主机名为db193:hostnamectl statushostnamectl set-hostname db193
hostnamectl status2.5 各节点创建需要的用户和组
创建group & user，给oracle、grid设置密码：
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
groupadd -g 54324 backupdba
groupadd -g 54325 dgdba
groupadd -g 54326 kmdba
groupadd -g 54327 asmdba
groupadd -g 54328 asmoper
groupadd -g 54329 asmadmin
groupadd -g 54330 racdba
useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle
useradd -u 54322 -g oinstall -G asmadmin,asmdba,asmoper,dba grid
echo oracle | passwd --stdin oracleecho oracle | passwd --stdin grid我这里测试环境设置密码都是oracle，实际生产环境建议设置符合规范的复杂密码。
2.6 各节点创建安装目录
各节点创建安装目录(root用户)：
mkdir -p /u01/app/19.3.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
chown -R grid:oinstall /u01
chown oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/2.7 各节点系统配置文件修改
内核参数修改：vi /etc/sysctl.conf
实际上OEL在安装依赖包的时候也同时修改了这些值，以下参数主要是核对或是对RHEL版本作为参考：
# vi /etc/sysctl.conf 增加如下内容：
vm.swappiness = 1vm.dirty_background_ratio = 3vm.dirty_ratio = 80vm.dirty_expire_centisecs = 500vm.dirty_writeback_centisecs = 100kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.panic_on_oops = 1net.ipv4.conf.enp0s8.rp_filter = 2net.ipv4.conf.enp0s9.rp_filter = 2net.ipv4.conf.enp0s10.rp_filter = 2修改生效：
#sysctl -p /etc/sysctl.conf注：enp0s9和enp0s10是IPSAN专用的网卡，跟私网一样设置loose mode。（我这里因为没有使用IPSAN，所以没有这两张网卡）
#sysctl -p /etc/sysctl.d/98-oracle.confnet.ipv4.conf.enp0s8.rp_filter = 2net.ipv4.conf.enp0s9.rp_filter = 2net.ipv4.conf.enp0s10.rp_filter = 2用户shell的限制：vi /etc/security/limits.d/99-grid-oracle-limits.conf

vi /etc/profile.d/oracle-grid.sh
#Setting the appropriate ulimits for oracle and grid userif [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536 else

if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384 ulimit -n 65536 else
ulimit -u 16384 -n 65536 fifi这个OEL中也没有自动配置，需要手工配置。
2.8 各节点设置用户的环境变量
第1个节点grid用户：
export ORACLE_SID=+ASM1;export ORACLE_BASE=/u01/app/grid;export ORACLE_HOME=/u01/app/19.3.0/grid;export PATH=$ORACLE_HOME/bin:$PATH;export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;第2个节点grid用户：

Linux平台 Oracle 19c RAC安装指导：
Part1： Linux平台 Oracle 19c RAC安装Part1：准备工作
Part2： Linux平台 Oracle 19c RAC安装Part2：GI配置
Part3： Linux平台 Oracle 19c RAC安装Part3：DB配置
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
三、GI(Grid Infrastructure)安装3.1 解压GI的安装包
su - grid
解压 GRID 到 GRID用户的$ORACLE_HOME下
[grid@db193 grid]$ pwd/u01/app/19.3.0/grid
[grid@db193 grid]$ unzip /u01/media/LINUX.X64_193000_grid_home.zip3.2 安装配置Xmanager软件
在自己的Windows系统上成功安装Xmanager Enterprise之后，运行Xstart.exe可执行程序，
配置如下
Session：db193
Host：192.168.1.193
Protocol：SSH
User Name：grid
Execution Command：/usr/bin/xterm -ls -display $DISPLAY
点击RUN，输入grid用户的密码可以正常弹出命令窗口界面，即配置成功。
当然也可以通过开启Xmanager - Passive，直接在SecureCRT连接的会话窗口中临时配置DISPLAY变量直接调用图形：
export DISPLAY=192.168.1.31:0.0
3.3 共享存储LUN的赋权
在《 Linux平台 Oracle 19c RAC安装Part1：准备工作 -> 1.3 共享存储规划》中已完成绑定和权限，这里不需要再次操作。
--只需确认两个节点链接文件(/dev/asm*)对应的sd[b-g]2的权限正确即可：
# ls -l /dev/sd?2brw-rw---- 1 root disk 8, 2 Jul 31 09:13 /dev/sda2brw-rw---- 1 grid asmadmin 8, 18 Jul 31 18:06 /dev/sdb2brw-rw---- 1 grid asmadmin 8, 34 Jul 31 18:06 /dev/sdc2brw-rw---- 1 grid asmadmin 8, 50 Jul 31 18:06 /dev/sdd2brw-rw---- 1 grid asmadmin 8, 66 Jul 31 17:10 /dev/sde2brw-rw---- 1 grid asmadmin 8, 82 Jul 31 17:10 /dev/sdf2brw-rw---- 1 grid asmadmin 8, 98 Jul 31 17:10 /dev/sdg23.4 使用Xmanager图形化界面配置GI
Xmanager通过grid用户登录，进入$ORACLE_HOME目录，运行gridSetup配置GI
$ cd $ORACLE_HOME$ ./gridSetup.sh其实从12cR2开始，GI的配置就跟之前有一些变化，19c也一样，下面来看下GI配置的整个图形化安装的过程截图： 
注：这里Public网卡这里用的enp0s3，ASM&Private这里用的enp0s8。 
注：这里有一个新的存储GIMR的，之前12c、18c版本都是选择是外部冗余的一个40G大小的盘（当初给很多刚接触安装12cRAC的DBA造成了不适），而在19c安装中可以看到默认就是不选择的，恢复了11g时代的清爽感，这点我个人觉得很赞。 
注：这里跟之前区别不大，我依然是选择3块1G的盘，Normal冗余作为OCR和voting disk。 
注：这里检查出来的问题都需要认真核对，确认确实可以忽略才可以点击“Ignore All”，如果这里检测出缺少某些RPM包，需要使用yum安装好。我这里是自己的测试环境，分的配置较低，所以有内存和swap检测不通过，实际生产环境不应出现。 
注：执行root脚本，确保先在一节点执行完毕后，再在其他节点执行。
第一个节点root执行脚本：

[root@db195 ~]#这段时间从打印的日志来看，虽然耗时也比以前11g时代长，但实际相比12c的上一个版本18c来说却缩短了不少。
root脚本成功执行完后继续安装: 
注：最后这个报错提示，查看日志发现是因为使用了一个scan ip的提示，可以忽略。 
至此GI配置完成。
3.5 验证crsctl的状态

Linux平台 Oracle 19c RAC安装指导：
Part1： Linux平台 Oracle 19c RAC安装Part1：准备工作
Part2： Linux平台 Oracle 19c RAC安装Part2：GI配置
Part3： Linux平台 Oracle 19c RAC安装Part3：DB配置
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
四、DB(Database)安装4.1 解压DB的安装包
oracle用户登录，在$ORACLE_HOME下解压db包（19c的db也是像18c一样直接解压到$ORACLE_HOME下，免安装）：
[oracle@db193 ~]$ mkdir -p /u01/app/oracle/product/19.3.0/db_1
[oracle@db193 ~]$ cd $ORACLE_HOME
[oracle@db193 db_1]$ pwd/u01/app/oracle/product/19.3.0/db_1
[oracle@db193 db_1]$ ls
[oracle@db193 db_1]$ unzip /u01/media/LINUX.X64_193000_db_home.zip4.2 DB软件配置
打开Xmanager软件，Oracle用户登录，配置数据库软件。
[oracle@db193 db_1]$ pwd/u01/app/oracle/product/19.3.0/db_1
[oracle@db193 db_1]$ export DISPLAY=192.168.1.31:0.0[oracle@db193 db_1]$ ./runInstaller下面截取DB软件配置的过程如下： 
注：这里选择只安装软件，数据库后面创建好ASM磁盘组后再运行dbca创建。 
注：配置好ssh等价性。 
注：可以进行修复的，按提示执行脚本修复。
我这里还有swap的问题，因为是测试环境资源有限，可以忽略，如果生产环境，强烈建议调整符合要求。
如果还有其他的检查项未通过，则无论是生产还是测试环境，都不建议忽略，而应该整改符合要求为止。 
注：最后root用户按安装提示执行1个脚本，需要在各节点分别执行。 
至此，已完成DB软件的配置。
4.3 ASMCA创建磁盘组
打开Xmanager软件，grid用户登录，asmca创建ASM磁盘组
[grid@db193 ~]$ export DISPLAY=192.168.1.31:0.0[grid@db193 ~]$ asmca使用asmca调用创建磁盘组的图形界面,首先映入眼帘的是鲜艳的19c配色图： 
然后正式进入asmca的界面： 
这里我先创建一个DATA磁盘组，一个FRA磁盘组，冗余选择external(生产如果选择external，底层存储必须已经做了RAID)。
这里看到新创建的DATA和FRA磁盘组已经创建完成并成功mount。
4.4 DBCA建库
打开Xmanager软件，oracle用户登录，dbca图形创建数据库。
下面是DBCA建库的过程截图： 
注：这里选择是否启用CDB，并定义CDB和PDB的名称。我选择启用CDB，CDB名称为jydb，并自动创建2个PDB，前缀名就叫pdb。 
注：这里我选择使用OMF，默认也是使用OMF。 
注：这里我暂时没有启用FRA，后续调整开归档时将归档文件放在+FRA磁盘组中。 
注：这里选择内存分配具体值，选择数据库的字符集，我这里没选择，字符集默认是AL32UTF8。需要根据实际情况修改。 
注：这里可以选择是否配置EM，我这里选择配置，如果你不需要，可以选择不配置。CVU一般也不配置，我这里学习目的选择配置。 
注：这里设置密码，我实验环境直接oracle，不符合规范，生产环境建议设置复杂密码。 
注：这里可以选择将创建数据库的脚本保存下来，根据你的需求，可选可不选。 
注：这里如果还有其他的检查未通过，则不能忽略。我这里是因为使用一个scan，对应报错可以忽略。 
注：这里是安装信息的概览，建议认真核实，如果有不对的还可以退回去改。确认无误后开始创建数据库。 
注：19c建库的时间还是和18c一样，长到让人崩溃，感觉以后DBA安装过程中可以提前下几个电影来边等边看了。
INFO: Aug 01, 2019 4:42:58 AM oracle.assistants.common.base.driver.AssistantConfigDriver updateExitStatus
INFO: Total time taken for DBCA operation in mm:ss is 286:16
至此，Oracle 19.3 RAC数据库已经创建成功，目前如果你的企业想上12c系列的数据库，推荐直接选择19c（12c的最终版本12.2.0.3），19c相对18c来说更趋于稳定，Oracle的支持周期也更长。
4.5 验证crsctl的状态
grid用户登录，crsctl stat res -t 查看集群资源的状态，发现各节点的DB资源已经正常Open。
