先上传安装包
linux.x64_11gR2_database_1of2.zip linux.x64_11gR2_database_2of2.zip
解压到本地
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip
安装一些yum包
yum install -y binutils* compat-libcap* compat-libstdc++* gcc* glibc* ksh* libaio* libgcc* libstdc++* libXi* libXtst* make* sysstat*
yum install glibc-static.x86_64 glibc-static.i686 -y
优化sysctl
vim /etc/sysctl.conf

fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096

net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
/sbin/sysctl -p
修改/etc/security/limits.conf
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
添加用户和用户组
添加用户组：（组id最好在500以后的值）
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper
添加用户并且分组：
/usr/sbin/useradd -g oinstall -G dba oracle
设置密码：
passwd oracle
创建oracle的安装目录
[root@centos01 database]# mkdir -p /u01/app
[root@centos01 database]# chown oracle:oinstall /u01/app/
[root@centos01 database]# chmod 755 /u01/app
[root@centos01 database]# mkdir -p /u01/app/oracle
[root@centos01 database]# chown oracle:oinstall /u01/app/oracle/
[root@centos01 database]# chmod 755 /u01/app/oracle
[root@centos01 database]# mkdir -p /u01/app/oracle/product/11.2.0/db_1
[root@centos01 database]# chown oracle:oinstall -R /u01/app/oracle
修改环境变量
[root@centos01 database]# su oracle
[oracle@centos01 ~]$ vim .bash_profile

排坑1：静默安装提示需要取消掉$DISPLAY
echo $DISPLAY
unset DISPLAY
echo $DISPLAY
排坑2：报错信息
[oracle@HOST database]$ [SEVERE] - Email Address Not Specified
解决方式：
修改responseFile文件db_install.rsp，将DECLINE_SECURITY_UPDATES=的值设为true，如果为空系统会假设该值为false，DECLINE_SECURITY_UPDATES=的值默认为空。
切换oracle用户开始安装
su - oracle
./runInstaller -silent -ignorePrereq -responseFile /opt/database/response/db_install.rsp
./runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /opt/database/response/db_install.rsp ---跳过检查，不是必要不建议加这个参数ignoreSysPrereqs
安装完成后切换root用户执行脚本
/u01/app/oracle/product/11.2.0/db_1/root.sh
静默安装数据库
修改配置文件
vim /opt/database/response/dbca.rsp

查看实例启动
ps -ef|grep smon
启动监控
lsnrctl start
进入数据库
export ORACLE_SID=orcl
sqlplus /nolog
SQL> connect /as sysdba
如果是关闭数据库，命令：shutdown abort
启动数据库，命令：startup
创建用户
SQL> create user admin identified by 888888;
SQL> grant connect,resource,dba to admin;
