一、配置环境变量

1、主机名配置

hostnamectl set-hostname orcl19C

2、网络配置

nmcli connection show
nmcli connection modify ens33 ipv4.addresses 192.168.30.81/24 ipv4.gateway 192.168.30.254 ipv4.method manual autoconnect yes
nmcli connection up ens33

3、配置Hosts文件

[root@orcl19c ~]# cat <<EOF >>/etc/hosts
192.168.30.81  orcl19C
##OracleEnd##
EOF

4、关闭防火墙

官方建议关闭数据库主机的防火墙，如果需要开启，请根据官方文档开启需要的端口。

systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld

5、关闭 Selinux

[root@orcl19c ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@orcl19c ~]# cat /etc/selinux/config

修改完 Selinux 配置文件后，需要重启主机进行生效！

6、配置 yum 源

确保虚拟机已经挂载 ISO 镜像之后，通过 mount 挂载镜像源到本地 /mnt 目录下：

[root@orcl19c ~]# mount /dev/cdrom /mnt
[root@orcl19c ~]# df -Th

配置本地 yum 文件，直接执行即可：

mkdir /etc/yum.repos.d/bak -p
mv /etc/yum.repos.d/* /etc/yum.repos.d/bak
cat<<EOF>/etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt
enabled=1
gpgcheck=0
EOF

yum repolist all

本地 yum 源就已经配置完成了。

7、安装依赖包

根据官方文档建议安装的依赖包，进行 yum install 安装：

yum install -y bc \
binutils \
compat-libcap1 \
compat-libstdc++-33 \
gcc \
gcc-c++ \
elfutils-libelf \
elfutils-libelf-devel \
glibc \
glibc-devel \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
libxcb \
libX11 \
libXau \
libXi \
libXtst \
libXrender \
libXrender-devel \
make \
net-tools \
nfs-utils \
smartmontools \
sysstat \
e2fsprogs \
e2fsprogs-libs \
fontconfig-devel \
expect \
unzip \
openssh-clients \
readline* \
psmisc --skip-broken

安装过程太长，不展示了，安装完之后检查一下是否都安装成功：

rpm -q bc binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ elfutils-libelf elfutils-libelf-devel glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libxcb libX11 libXau libXi libXtst libXrender libXrender-devel make net-tools nfs-utils smartmontools sysstat e2fsprogs e2fsprogs-libs fontconfig-devel expect unzip openssh-clients readline

RHEL 7 需要手动安装 compat-libstdc++ 依赖包：

[root@orcl19c yum.repos.d]# mkdir /soft
cd /soft
rpm -ivh compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

8、配置 hosts

hosts 文件单机情况下可以忽略配置，按照规范和习惯还是建议配置一下：

cat <<EOF >>/etc/hosts
192.168.30.81  orcl19C      
EOF

9、创建用户和组

Oracle 19C 官方文档增加了几个组，我们这里都加上：

## 创建 oinstall dba oper 组
/usr/sbin/groupadd -g 54321 oinstall
/usr/sbin/groupadd -g 54322 dba
/usr/sbin/groupadd -g 54323 oper
/usr/sbin/groupadd -g 54324 backupdba
/usr/sbin/groupadd -g 54325 dgdba
/usr/sbin/groupadd -g 54326 kmdba
/usr/sbin/groupadd -g 54330 racdba
## 创建 oracle 用户
/usr/sbin/useradd -u 54321 -g oinstall -G dba,backupdba,dgdba,kmdba,racdba,oper oracle
## 修改 oracle 用户密码为 oracle
echo oracle | passwd --stdin oracle
## 检查 oracle 用户
id oracle

10、创建安装目录

在正式安装 Oracle 数据库之前先配置好安装目录：

mkdir -p /u01/app/oracle/product/19.3.0/db
mkdir -p /u01/app/oraInventory
mkdir -p /oradata
mkdir -p /archivelog
chown -R oracle:oinstall /oradata
chown -R oracle:oinstall /archivelog
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app

11、配置 avahi-deamon

官方文档建议关闭 avahi-deamon 和 NOZEROCONF：

systemctl stop avahi-daemon.socket
systemctl stop avahi-daemon.service
systemctl disable avahi-daemon.service
systemctl disable avahi-daemon.socket

##关闭 NOZEROCONF
cat <<EOF >>/etc/sysconfig/network
NOZEROCONF=yes
EOF

12、关闭透明大页和 numa

官方建议关闭透明大页和 numa，有一些 BUG 是由于这两个特性导致，并且打开对数据库的性能提升不大，因此直接关闭即可。

RHEL 7 可以直接修改内核来关闭透明大页和 numa：

sed -i 's/quiet/quiet transparent_hugepage=never numa=off/' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg

[root@orcl19c soft]# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-1160.el7.x86_64
Found initrd image: /boot/initramfs-3.10.0-1160.el7.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-c2f977e78ba3407b9c98e973b6274b1c
Found initrd image: /boot/initramfs-0-rescue-c2f977e78ba3407b9c98e973b6274b1c.img
done

透明大页和 numa 的配置需要重启主机生效，这里先不重启，等全部配置完之后再重启主机！

13、配置系统参数文件

根据官方文档将参数整合成一个脚本命令，直接复制下方命令执行即可：

DAYTIME=$(date +%Y%m%d)
mv /etc/sysctl.conf /etc/sysctl.conf.${DAYTIME}
memTotal=$(grep MemTotal /proc/meminfo | awk '{print $2}')
totalMemory=$((memTotal / 2048))
shmall=$((memTotal / 4))
if [ $shmall -lt 2097152 ]; then
  shmall=2097152
fi
shmmax=$((memTotal * 1024 - 1))
if [ "$shmmax" -lt 4294967295 ]; then
  shmmax=4294967295
fi
cat <<EOF >/etc/sysctl.conf
##shmmal's Calculation formula: physical memory 8G：(8*1024*1024*1024)/4096=2097152
##shmmax's Calculation formula: physical memory 8G：(8/2)*1024*1024*1024 -1=4294967295
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = $shmall
kernel.shmmax = $shmmax
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 = 1048576
EOF

sysctl -p

14、配置系统资源限制

cat <<EOF >>/etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle soft nproc 2047
oracle hard nproc 16384
oracle hard memlock 134217728
oracle soft memlock 134217728
EOF

15、配置 pam.d

cat <<EOF >>/etc/pam.d/login
session required pam_limits.so 
session required /lib64/security/pam_limits.so
EOF

16、配置 /dev/shm

cp /etc/fstab /tmp/fstab
memTotal=$(grep MemTotal /proc/meminfo | awk '{print $2}')
shmTotal=$(df -k /dev/shm | awk '{print $2}' | head -n 2 | tail -n 1)
if [ "$(grep -E -c "/dev/shm" /etc/fstab)" -eq 0 ]; then
	cat <<EOF >>/etc/fstab
tmpfs /dev/shm tmpfs size=${memTotal}k 0 0
EOF
	mount -o remount /dev/shm
else
  if [ "$shmTotal" -lt "$memTotal" ]; then
    shmTotal=$memTotal
    line=$(grep -n "/dev/shm" /etc/fstab | awk -F ":" '{print $1}')
    sed -i "${line} d" /etc/fstab
    cat <<EOF >>/etc/fstab
tmpfs /dev/shm tmpfs size=${memTotal}k 0 0
EOF
	fi
	mount -o remount /dev/shm
fi

17、配置用户环境变量

## 配置 root 用户
cat <<EOF >>/root/.bash_profile
alias so='su - oracle'
export PS1="[\`whoami\`@\`hostname\`:"'\$PWD]# '
EOF

## 配置 oracle 用户
cat <<EOF >>/home/oracle/.bash_profile
umask 022
export TMP=/tmp
export TMPDIR=\$TMP
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/19.3.0/db
export ORACLE_HOSTNAME=orcl19C
export ORACLE_TERM=xterm
export TNS_ADMIN=\$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=\$ORACLE_HOME/lib:/lib:/usr/lib
export ORACLE_SID=orcl
export PATH=/usr/sbin:\$PATH
export PATH=\$ORACLE_HOME/bin:\$ORACLE_HOME/OPatch:\$PATH
alias sas='sqlplus / as sysdba'
export PS1="[\`whoami\`@\`hostname\`:"'\$PWD]\$ '
EOF

至此，Linux 操作系统的配置就完成了，重启主机确保配置没有！重启成功后检查一下 Selinux，透明大页和 numa：

cat /etc/selinux/config
cat /sys/kernel/mm/transparent_hugepage/enabled
cat /proc/cmdline

三、安装 Oracle 软件

从 18C 开始要求将 Database 安装包解压至 ORACLE_HOME 目录下，手动解压一下 RU 和 OPatch 补丁，用于补丁安装！

1、配置响应文件

可以看到静默安装可以使用一个响应文件 -responseFile 来进行配置，所以我们要先编辑响应文件：

## 首先需要授予 /soft 目录权限
chown -R oracle.oinstall /soft
## 连接 oracle 用户
su - oracle
cd /soft
## 配置 oracle 软件安装目录
ENV_BASE_DIR=/u01/app
## 创建响应文件
cat <<EOF >>/soft/db.rsp
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v19.0.0
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=${ENV_BASE_DIR}/oraInventory
ORACLE_BASE=$ORACLE_BASE
oracle.install.db.InstallEdition=EE
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSOPER_GROUP=oper
oracle.install.db.OSBACKUPDBA_GROUP=backupdba
oracle.install.db.OSDGDBA_GROUP=dgdba
oracle.install.db.OSKMDBA_GROUP=kmdba
oracle.install.db.OSRACDBA_GROUP=racdba
oracle.install.db.rootconfig.executeRootScript=false
oracle.install.db.rootconfig.configMethod=
EOF

如上所示，为 Oracle 软件安装的响应文件，如需修改安装目录，只需要改变 ENV_BASE_DIR 参数值即可！

## 先授权 /soft 
chown -R oracle.oinstall /soft
## 切换至 oracle 用户
su - oracle
cd /soft
[oracle@orcl19c:/soft]$ ll
total 4484356
-rw-r--r--. 1 oracle oinstall     195388 Jun 20 15:03 compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
-rw-r--r--  1 oracle oinstall        590 Jun 20 16:11 db.rsp
-rw-r--r--  1 root   root     3059705302 Jun 20 15:24 LINUX.X64_193000_db_home.zip
-rw-r--r--  1 root   root     1411305781 Jun 20 16:10 p33192793_190000_Linux-x86-64.zip
-rw-r--r--  1 root   root      120761121 Jun 20 15:24 p6880880_190000_Linux-x86-64.zip


[oracle@orcl19c:/soft]$ unzip -q LINUX.X64_193000_db_home.zip -d $ORACLE_HOME

2、RU 补丁安装

Oracle 19C 支持在安装 Oracle 软件之前就打好补丁，因此我们可以提前打 RU 补丁，更加省事快捷，不需要看 README 文档，直接安装时一个 -applyRU 参数就可以搞定！

首先，我们先解压好 OPatch 和 RU 补丁包，打补丁需要放在安装时执行：

## 直接静默覆盖解压 p6880880 到 ORACLE_HOME 目录，前面解压是为了给大家看 README 文档，一般都是直接解压到 ORACLE_HOME 目录下
[oracle@orcl19c:/soft]$ unzip -o -q /soft/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
## 检查 OPatch 版本
opatch version
## 解压 RU 补丁包
[oracle@orcl19c:/soft]$ unzip -q p33192793_190000_Linux-x86-64.zip

如上，已经成功解压好 RU 补丁和 OPatch 安装包。

3、静默安装 Oracle 软件

配置好响应文件之后，就可以开始静默安装 Oracle 软件了，并提前安装 RU 补丁，很简单的一行命令：

cd $ORACLE_HOME
./runInstaller -silent -force -responseFile /soft/db.rsp -ignorePrereq -waitForCompletion -applyRU /soft/33192793

以上1.2.3步骤执行过程

[oracle@orcl19c:/soft]$ unzip -q LINUX.X64_193000_db_home.zip -d $ORACLE_HOME
[oracle@orcl19c:/soft]$ opatch version
OPatch Version: 12.2.0.1.17

OPatch succeeded.
[oracle@orcl19c:/soft]$ unzip -o -q /soft/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
[oracle@orcl19c:/soft]$ opatch version
OPatch Version: 12.2.0.1.27

OPatch succeeded.
[oracle@orcl19c:/soft]$ unzip -q p33192793_190000_Linux-x86-64.zip
[oracle@orcl19c:/soft]$ cd $ORACLE_HOME
[oracle@orcl19c:/u01/app/oracle/product/19.3.0/db]$ ./runInstaller -silent -force -responseFile /soft/db.rsp -ignorePrereq -waitForCompletion -applyRU /soft/33192793

        2. /u01/app/oracle/product/19.3.0/db/root.sh

Execute /u01/app/oraInventory/orainstRoot.sh on the following nodes:
[orcl19c]
Execute /u01/app/oracle/product/19.3.0/db/root.sh on the following nodes:
[orcl19c]


Successfully Setup Software.
Moved the install session logs to:
 /u01/app/oraInventory/logs/InstallActions2022-06-20_05-25-32

打补丁需要等待一段时间，安装完后需要切换到 root 用户下执行以下 root.sh 脚本：

/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/19.3.0/db/root.sh

恭喜，Oracle 软件安装成功啦！

四、创建监听

静默创建监听就更简单了，netca 一行命令：

netca -silent -responsefile $ORACLE_HOME/assistants/netca/netca.rsp
## 检查监听状态
lsnrctl status

[oracle@orcl19c:/u01/app/oracle/product/19.3.0/db]$ netca -silent -responsefile $ORACLE_HOME/assistants/netca/netca.rsp

Parsing command line arguments:
    Parameter "silent" = true
    Parameter "responsefile" = /u01/app/oracle/product/19.3.0/db/assistants/netca/netca.rsp
Done parsing command line arguments.

[oracle@orcl19c:/u01/app/oracle/product/19.3.0/db]$

如上所示，即配置成功，由于还没有创建数据库实例，所以监听不到任何服务，这是正常的。

五、创建数据库实例

来吧，最后一步啦，创建数据库实例，建完库之后，咱们就完成一套数据库的完整安装了！

创建数据库实例当然也是可以用静默创建的，也是一条说简单不简单的命令，首先我们配置下关键信息：

## 实例名称
ORACLE_SID=orcl
## 数据文件目录
ORADATADIR=/oradata
## 归档日志目录
ARCHIVEDIR=/archivelog
## 数据库字符集
CHARACTERSET=AL32UTF8
## 国家字符集
NCHARACTERSET=AL16UTF16
## 数据库内存这里取物理内存的 50%
memTotal=$(grep MemTotal /proc/meminfo | awk '{print $2}')
totalMemory=$((memTotal / 2048))
## 是否为 CDB 模式，TRUE 或者 FALSE
ISCDB=TRUE

正式开始静默创建数据库实例：

dbca -silent -createDatabase \
-ignorePrereqFailure \
-templateName General_Purpose.dbc \
-responseFile NO_VALUE \
-gdbName ${ORACLE_SID} \
-sid ${ORACLE_SID} \
-sysPassword oracle \
-systemPassword oracle \
-redoLogFileSize 1024 \
-storageType FS \
-databaseConfigType SINGLE \
-datafileDestination ${ORADATADIR} \
-enableArchive true \
-archiveLogDest ${ARCHIVEDIR} \
-characterset ${CHARACTERSET} \
-nationalCharacterSet ${NCHARACTERSET} \
-emConfiguration NONE \
-automaticMemoryManagement false \
-totalMemory ${totalMemory} \
-databaseType OLTP \
-createAsContainerDatabase ${ISCDB}

19C 安装比较慢，执行过程

[oracle@orcl19c:/u01/app/oracle/product/19.3.0/db]$ ## 实例名称
[oracle@orcl19c:/u01/app/oracle/product/19.3.0/db]$ ORACLE_SID=orcl
