说明：本文的所有步骤不适用于生产环境，仅用于个人测试环境的快速部署和学习，下述操作过程在Oracle Linux 7.9上安装Oracle 11.2.0.4单实例为例。
1 安装环境检查
安装环境的检查可以参考官方文档Oracle Database Quick Installation Guide for Linux x86-64。由于是测试环境，本文仅检查：
- 物理内存大于1G。使用
free -m命令检查 - /tmp目录大于200MB。使用
df -h命令检查，默认/tmp目录在根分区中，会大于200MB - hosts文件有对应的IP和主机名解析。使用
cat /etc/hosts检查 - 安装和建库需要约10GB的空间。本文安装在
/u01，未使用独立的分区，也隶属于根分区中，有40GB的空间。
2 安装环境准备
2.1 准备Oracle用户和目录
使用root用户创建软件安装目录/u01/app/oracle/product/11.2.0.4/db_1，创建oinstall、dba、oper用户组，创建oracle用户，并且为oracle用户设置密码。
groupadd -g 1300 oinstall
groupadd -g 1301 dba
groupadd -g 1302 oper
useradd -u 1300 -g oinstall -G dba,oper -s /bin/bash oracle
mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle.oinstall /u01
passwd oracle
2.2 检查和安装所需的RPM包
- 使用rpm检查软件包是否已安装，如果未安装，则会提示
is not installed。
rpm -q --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})n" binutils compat-db compat-libcap1 compat-libstdc++-33 control-center elfutils-libelf-devel gcc gcc-c++ glibc-common glibc glibc-devel glibc-headers ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel libgomp libXp make sysstat unzip
- 配置本地yum源，确保
/etc/yum.repos.d/目录下仅有oracle-linux-ol7.repo配置文件
[root@oracle11g ~]# cat /etc/yum.repos.d/oracle-linux-ol7.repo
[ol7_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=file:///media/OEL79
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1
[root@oracle11g ~]# df -h | grep OEL
/dev/sr0 4.6G 4.6G 0 100% /media/OEL79
[root@oracle11g ~]# yum makecache
Loaded plugins: ulninfo
ol7_latest | 3.6 kB 00:00:00
Metadata Cache Created
- 使用yum安装软件包
yum install binutils compat-db compat-libcap1 compat-libstdc++-33 control-center elfutils-libelf-devel gcc gcc-c++ glibc-common glibc glibc-devel glibc-headers ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel libgomp libXp make sysstat unzip -y
2.3 修改配置参数
- 修改pam认证机制，加载
pam_limits.so模块来限制系统资源的使用
echo "session required pam_limits.so">>/etc/pam.d/login
- 配置oracle用户的资源限制，限制打开进程数量和文件数量
echo "oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
">>/etc/security/limits.conf
- 修改profile，Linux中初始化shell时会使用该配置文件，当用户登录系统时，系统会首先加载/etc/profile文件，然后再加载用户个人的shell初始化文件，如~/.bash_profile等。
echo "if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
">>/etc/profile
- 修改内核参数，限制信号量、端口、文件数量等
echo "fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 15461882265 #16GB
kernel.shmmax = 4294967295 #4GB
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
">>/etc/sysctl.conf
内核参数介绍：
- fs.aio-max-nr = 1048576：控制系统异步输入输出操作（Asynchronous I/O）并发数的最大值，影响系统的数据传输效率和压力处理能力。
- fs.file-max = 6815744：表示系统最大文件打开数量，默认是1024，可能会造成系统资源不足或进程无法打开文件等问题。
- kernel.shmall = 15461882265：定义了系统使用的最大共享内存容量，以页面（4K）为单位，这里设置的是16GB。
- kernel.shmmax = 4294967295：定义了用户进程可使用的共享内存大小，以字节为单位，这里设置的是4GB。
- kernel.shmmni = 4096：定义了系统最大的共享内存区数量。
- kernel.sem = 250 32000 100 128：设置内核信号量的值。后面的数字分别表示“信号量数组的数量”、“每个信号量数组中信号量的数目”、“系统所允许的信号量总数”和“一个信号量能带有的最大值”。
- net.ipv4.ip_local_port_range = 9000 65500：设置本地端口范围。这里设置了本地端口的最小和最大值，限制要使用该端口的进程数量。
- net.core.rmem_default = 262144：表示系统默认接收缓存区大小。
- net.core.rmem_max = 4194304：表示系统中接收缓存区的最大数量，用来调节系统接收性能。
- net.core.wmem_default = 262144：表示系统默认发送缓存区大小。
- net.core.wmem_max = 1048576：表示系统中发送缓存区的最大数量，用来调节系统发送性能。
- 配置oracle用户的环境变量，设置实例名为
orcl、安装路径为/u01/app/oracle/product/11.2.0.4/db_1
export ORACLE_SID=orcl
export ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1
echo "export ORACLE_SID=$ORACLE_SID
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:/usr/local/lib
export PATH=$ORACLE_HOME/bin:$PATH:$ORACLE_HOME/OPatch
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
umask 022
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export SQLPATH=$ORACLE_HOME/sqlplus/admin
">>/home/oracle/.bash_profile
2.4 关闭selinux和防火墙
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
systemctl disable firewalld --now
完成上述操作后，需要重启操作系统才生效
reboot
2.5 准备软件安装包
- 将安装包放在/tmp目录下
unzip p13390677_112040_Linux-x86-64_1of7.zip
unzip p13390677_112040_Linux-x86-64_2of7.zip
- 更改安装包的属组和用户为oinstall和oracle
chown -R oracle.oinstall /tmp/database
2.6 创建响应文件
需要留意的是UNIX_GROUP_NAME、INVENTORY_LOCATION、ORACLE_HOME、ORACLE_BASE,保持和前文的创建的用户名、安装路径一致。
echo "oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=DBProduce

3 执行静默安装
- 使用oracle用户，执行
./runInstaller,注意-responseFile要用绝对路径
cd /tmp/database
./runInstaller -ignoreSysPrereqs -ignorePrereq -waitforcompletion -showProgress -silent -responseFile /tmp/11gR2.rsp
- 安装过程输出

/u01/app/oracle/product/11.2.0.4/db_1/root.sh
5 执行静默建库
5.1 创建监听
- 准备netca响应文件
echo 'RESPONSEFILE_VERSION="11.2"
CREATE_TYPE="CUSTOM"
INSTALLED_COMPONENTS={"server","net8″,"javavm"}
INSTALL_TYPE=""typical""
LISTENER_NUMBER=1
LISTENER_NAMES={"LISTENER"}
LISTENER_PROTOCOLS={"TCP;1521"}
LISTENER_START=""LISTENER""
NAMING_METHODS={"TNSNAMES","ONAMES","HOSTNAME"}
NSN_NUMBER=1
NSN_NAMES={"EXTPROC_CONNECTION_DATA"}
NSN_SERVICE={"PLSExtProc"}
NSN_PROTOCOLS={"TCP;HOSTNAME;1521"'>>/tmp/netca.rsp
- 执行静默安装，注意是
/responsefile,而且响应文件要绝对路径
netca /silent /responsefile /tmp/netca.rsp
- 配置成功后，输出如下：
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /u01/install/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Oracle Net Services configuration successful. The exit code is 0
- 启动监听程序

5.2 执行静默建库
- 使用
oracle用户执行dbca命令来完成静默建库，安装过程中会自动创建/u01/app/oracle/oradata目录，并拷贝数据文件和生成控制文件、日志文件,将所有密码设置为oracle11g。
dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname orcl -sid orcl -responseFile NO_VALUE -characterSet ZHS16GBK -memoryPercentage 75 -emConfiguration LOCAL -datafiledestination /u01/app/oracle/oradata -sysPassword oracle11g -systemPassword oracle11g -dbsnmpPassword oracle11g -sysmanPassword oracle11g
