相比Windows，在Linux安装Oracle的步骤可能略显繁琐，同时Oracle提供了静默安装方法在不适用图形界面的情况下进行安装，我们本次使用静默安装。为了避免以后忘记，因此我将本次安装过程记录，当日后需要的时候，可以再次回顾。
本人环境：CentOS 7.6 64位
安装版本：Oracle 11.2.0
关于 Oracle 11g 的安装包，我们可以直接到官网上下载。
下载链接：https://www.oracle.com/database/technologies/oracle-database-software-downloads.html
下载完成之后，我们需要将安装包上传到Linux服务器上，Oracle 11g的安装包比较大，因此我借助了 WinSCP 文件传输软件来完成上传，最终，Linux服务器上得到的安装包如下。
接着，将安装包依次解压，命令如下：
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip
解压完成，会得到一个database的文件夹。
在这里，需要安装一些依赖包，命令如下：
yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat unixODBC unixODBC-devel
安装之后，需要检查下依赖包是否安装完整，过滤出未安装完整的依赖，命令如下：
rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat unixODBC unixODBC-devel | grep "not installed"
如果发现有未安装的，可以通过 yum 安装，或者通过 wget 命令下载rpm包，再手动安装。
[root@VM_0_8_centos database]# rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat unixODBC unixODBC-devel | grep "not installed"
package pdksh is not installed
[root@VM_0_8_centos database]#
如上，发现 pdksh 没有安装，通过 yum 安装。
[root@VM_0_8_centos database]# yum -y install pdksh
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
No package pdksh available.
Error: Nothing to do
[root@VM_0_8_centos database]#
可以看到没有相关安装包可用，那么只能通过 wget 命令直接下载rpm包后手动安装，命令如下：
mkdir /software/temp
wget -O /software/temp/pdksh-5.2.14-37.el5_8.1.x86_64.rpm http://vault.centos.org/5.11/os/x86_64/CentOS/pdksh-5.2.14-37.el5_8.1.x86_64.rpm
下载完成，进入刚创建的临时目录 /software/temp ，通过命令 rpm -ivh 进行手动安装。
[root@VM_0_8_centos software]# cd /software/temp
[root@VM_0_8_centos temp]# ls
pdksh-5.2.14-37.el5_8.1.x86_64.rpm
[root@VM_0_8_centos temp]# rpm -ivh pdksh-5.2.14-37.el5_8.1.x86_64.rpm

再次检查下依赖包是否完整，确保所需依赖包都已安装。
# 创建用户

groupadd asmdba
useradd -g oinstall -G dba,asmdba oracle -d /home/oracle

[root@VM_0_8_centos software]# chown oracle:oinstall -R /software
可以将服务器名写入到hosts文件，这样以后就可以通过服务器名来进行连接。
vi /etc/hosts
在文件末加入 127.0.0.1 oracledb localhost localhost.localdomain，最后保存退出。
测试是否配置成功，则执行命令：ping -c 3 oracledb
[root@VM_0_8_centos temp]# ping -c 3 oracledb

vi /etc/sysctl.conf
将 kernel.shmmax 与 kernel.shmall 注释掉，然后在文件末追加新配置内容。以下是从网上收集到的一些配置，需根据自己服务器内存选择追加的内容，仅供参考。
# 主机是4G内存选用
kernel.shmmax = 4294967296
kernel.shmall = 4294967296
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
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
fs.aio-max-nr=1048576
# 主机是32G内存选用
kernel.shmmax = 17179869184

net.core.wmem_default=262144
net.core.wmem_max=1048576
fs.aio-max-nr=1048576
修改参数之后，我们需要让参数生效，执行命令：sysctl -p。
cat /etc/selinux/config
vi /etc/security/limits.conf
在文件末追加以下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
vi /etc/pam.d/login
在文件末追加以下内容：
session required /lib64/security/pam_limits.so
session required pam_limits.so
vi /etc/profile
在文件末追加以下内容：
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
为了让上面修改的环境变量立即生效，执行命令：source /etc/profile。
su - oracle
vi .bash_profile
在文件末追加以下内容：
umask 022
export ORACLE_HOSTNAME=oracledb
export ORACLE_BASE=/software/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export TNS_ADMIN=$ORACLE_HOME/network/admin
# export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
export NLS_LANG="AMERICAN_CHINA.ZHS16GBK"
OK，到这里我们的准备工作已经差不多，接下来就是静默安装配置和正式安装了，我们最好重启下服务器，执行命令：reboot。
进入 /software/database （之前解压生成的目录），需要修改一下响应文件：vi /software/database/response/db_install.rsp，参考了网上文章，需要修改的内容如下：
# 选择安装类型：1.只装数据库软件 2.安装数据库软件并建库 3.升级数据库
oracle.install.option=INSTALL_DB_SWONLY
# 指定操作系统主机名，通过hostname命令获得
ORACLE_HOSTNAME=oracledb
# 指定oracle inventory目录的所有者，通常会是oinstall或者dba
UNIX_GROUP_NAME=oinstall
# 指定产品清单oracle inventory目录的路径
INVENTORY_LOCATION=/software/app/oracle/inventory
# 指定数据库语言，可以选择多个，用逗号隔开
SELECTED_LANGUAGES=en,zh_CN
# 设置ORALCE_HOME的路径
ORACLE_HOME=/software/app/oracle/product/11.2.0/dbhome_1
# 设置ORALCE_BASE的路径
ORACLE_BASE=/software/app/oracle
# 选择Oracle安装数据库软件的版本
oracle.install.db.InstallEdition=EE
# 是否自定义安装
oracle.install.db.isCustomInstall=false
# 指定拥有OSDBA、OSOPER权限的用户组，通常会是dba组
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
# 选择数据库的用途，一般用途/事物处理，数据仓库
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE
# 指定SID
oracle.install.db.config.starterdb.SID=orcl
# 选择字符集，我这里选择有ZHS16GBK简体中文库
oracle.install.db.config.starterdb.characterSet=ZHS16GBK
# 是否设置安全更新，这里一定要设置为true
DECLINE_SECURITY_UPDATES=true
下面就是正式安装了，切换到oracle用户，命令：su - oracle，进入 /software/database 文件夹目录，执行以下命令，开始安装。
./runInstaller -silent -ignorePrereq -responseFile /software/database/response/db_install.rsp
在安装过程中，界面会提示告诉我们，可以到具体的日志路径下查看安装日志，使用 tail -f 实时监控日志即可。
[oracle@VM_0_8_centos database]$ ./runInstaller -silent -ignorePrereq -responseFile /software/database/response/db_install.rsp

/software/app/oracle/product/11.2.0/dbhome_1/root.sh
最后，按回车键完成Oracle安装。
切换到oracle用户，命令：su - oracle，进入 /software/database 文件夹目录，执行命令：netca /silent /responsefile /software/database/response/netca.rsp，开始配置监听。
[oracle@VM_0_8_centos database]$ netca /silent /responsefile /software/database/response/netca.rsp

根据自己需要修改，比如这样：

SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION =/software/app/oracle/oradata

# 根据实际情况设置字符集

我们可以使用Oracle用户，通过命令 lsnrctl status 查看监听状态。
[oracle@VM_0_8_centos ~]$ lsnrctl status

OK，到这里已经成功在Linux下安装Oracle。
接下来，我们用上面设置的密码 SYSPASSWORD = "oracle"来验证是否能正常登录。
[oracle@VM_0_8_centos ~]$ sqlplus sys/oracle@orcl as sysdba

最后，我们还需要配置一下，让Oracle能够在服务器开机时自动启动。
vi /etc/oratab
使用root用户，修改 /etc/oratab 配置内容，设置如下：orcl:/software/app/oracle/product/11.2.0/dbhome_1:Y。其中，/software/app/oracle/product/11.2.0/dbhome_1为之前设置的 $ORACLE_HOME 路径。
vi /etc/rc.d/rc.local
su oracle -lc "/software/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"
su oracle -lc "/software/app/oracle/product/11.2.0/dbhome_1/bin/dbstart"
在CentOS7下，我们还需要检查文件 /etc/rc.d/rc.local 是否有执行权限，如果没有执行权限，则需执行命令：chmod +x /etc/rc.d/rc.local。
完成以后操作后，需要验证一下，执行重启命令：reboot，重启之后先执行命令：su - oracle 切换到Oracle，再执行命令 lsnrctl status 查看监听状态，同时可以正常进行Oracle登录，说明开机自启动是没问题的。

在Oracle静默安装过程中，查看安装日志，发现出现错误并提示 swap空间 不够。
使用 free -m 命令查看swap大小，发现大小为0，难怪会提示空间小于150M。因此，我们需要给服务器增加swap虚拟空间。
[root@VM_0_8_centos /]# free -m
total used free shared buff/cache available
Mem: 32009 312 31455 0 242 31377
Swap: 0 0 0
参考了网上资料，给Linux主机创建了2G的swap文件，创建过程如下：
[root@VM_0_8_centos /]# dd if=/dev/zero of=/software/swap bs=2048 count=1048576
1048576+0 records in
1048576+0 records out

Swap: 2047 0 2047
[root@VM_0_8_centos /]#
为了让开机时自动启用，还需修改文件 /etc/fstab 添加一行：
/software/swap swap swap defaults 0 0
我们使用oracle用户来操作，查看监听状态时，可能提示命令找不到。
[root@VM_0_8_centos ~]# su oracle
[oracle@VM_0_8_centos root]$ cd ~
[oracle@VM_0_8_centos ~]$ lsnrctl status
bash: lsnrctl: command not found
[oracle@VM_0_8_centos ~]$ ^C
[oracle@VM_0_8_centos ~]$
这是因为，在这里切换帐户一定要加 -，即使用 su - oracle，否则就会出现上面的错误。
