服务器采用的是阿里云，具体看下面
[root@aliyun_test var]# cat /etc/system-release
CentOS release 6.5 (Final)
[root@aliyun_test var]# uname -r
2.6.32-431.23.3.el6.x86_64
[root@aliyun_test var]# uname -n
aliyun_test
内存：
由于阿里云默认是没有swap的，所以这个需要自己创建，后面会提到如何创建
静默安装前一些必要的操作
#####install java
rpm -ivh jdk-7u75-linux-x64.rpm
echo "export JAVA_HOME=/usr/java/jdk1.7.0_75" >> /etc/profile.d/java.sh
echo "export PATH=$JAVA_HOME/bin:$PATH" >> /etc/profile.d/java.sh
echo "export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar" >>/etc/profile.d/java.sh
. /etc/profile.d/java.sh
######verify java
java -version
一些必须的包
yum -y install binutils compat-libstdc++-33 compat-libstdc++-33.i686 ksh elfutils-libelf \
elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio \
libaio.i686 libaio-devel libaio-devel.i686 libgcc libstdc++ libstdc++.i686 \
libstdc++-devel libstdc++-devel.i686 make sysstat unixODBC unixODBC-devel unzip
然后是一些内核参数调整
########modify /etc/sysctl.conf
echo "fs.aio-max-nr = 1048576" >> /etc/sysctl.conf
echo "fs.file-max = 6815744" >> /etc/sysctl.conf
echo "kernel.shmmni = 4096" >> /etc/sysctl.conf
echo "kernel.sem = 250 32000 100 128" >> /etc/sysctl.conf
echo "net.ipv4.ip_local_port_range = 9000 65500" >> /etc/sysctl.conf
echo "net.core.rmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.rmem_max = 4194304" >> /etc/sysctl.conf
echo "net.core.wmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.wmem_max = 1048576" >> /etc/sysctl.conf
/sbin/sysctl -p
然后是软硬文件打开数
##############modify /etc/security/limits.conf
echo "oracle soft nproc 2047" >> /etc/security/limits.conf
echo "oracle hard nproc 16384" >> /etc/security/limits.conf
echo "oracle soft nofile 1024" >> /etc/security/limits.conf
echo "oracle hard nofile 65536" >> /etc/security/limits.conf
创建oracle用户
#########create user oracle
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba oracle
passwd oracle
mkdir /u01/app -p
chown -R oracle:oinstall /u01
chmod 755 /u01/app
创建oracle清单文件
########create oraInventory
echo "inventory_loc=/u01/app/oraInventory" >> /etc/oraInst.loc
echo "inst_group=oinstall" >> /etc/oraInst.loc
chown -R oracle:oinstall /etc/oraInst.loc
chmod 755 /etc/oraInst.loc
添加登录认证
########modify /etc/pam.d/login
#add
session required pam_limits.so
修改/etc/profile 限制其他用户使用
############modify /etc/profile
# add follows to the end
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
然后切换oracle用户进行操作
#########for oracle user
su - oracle
cd /home/oracle
file1:wget http://download.oracle.com/otn/linux/oracle11g/R2/linux.x64_11gR2_database_1of2.zip
file2:wget http://download.oracle.com/otn/linux/oracle11g/R2/linux.x64_11gR2_database_2of2.zip
vim .bash_profile
export ORACLE_BASE=/u01/app
export ORACLE_SID=test
unzip linux.x64_11gR2_database_1of2.zip -d /u01/app
unzip linux.x64_11gR2_database_2of2.zip -d /u01/app
由于是使用静默文件安装oracle，所以必须创建修改响应文件（具体参数说明请参考官方网站）
cp /u01/app/database/response/db_install.rsp /home/oracle
chmod 700 /home/oracle/*.rsp
####add to rsp
修改以下值
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=oracle11g
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
SELECTED_LANGUAGES=en,zh_CN,zh_TW
ORACLE_HOME=/u01/app/product/11.2.0/dbhome_1
ORACLE_BASE=/u01/app
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=false
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oinstall
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE
oracle.install.db.config.starterdb.globalDBName=test
oracle.install.db.config.starterdb.SID=test
oracle.install.db.config.starterdb.memoryLimit=512
oracle.install.db.config.starterdb.password.ALL=redhat
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
准备工作就绪后，于是进行安装
#######silent install oracle
cd /u01/app
./database/runInstaller -silent -responseFile /home/oracle/db_install.rsp
请根据屏幕上的输出信息进行相应的措施（由于是阿里云主机，swap要求没有达到）
swap内存做如下操作：
如果交换空间不够：针对阿里云主机或者swap为0的主机
dd if=/dev/zero of=/test bs=1G count=4----》如果这种方法不行，请选择下面
mkswap -f /test
swapon /test
free -m
设置2G的swap空间
[root@aliyun_test var]# dd if=/dev/zero of=/var/test bs=1G count=2
dd: memory exhausted
[root@aliyun_test var]# dd if=/dev/zero of=/var/test bs=1024 count=2097152
2097152+0 records in
2097152+0 records out
2147483648 bytes (2.1 GB) copied, 38.0205 s, 56.5 MB/s
[root@aliyun_test var]# du -sh /var/test

[root@aliyun_test var]# mkswap -f /var/test

total used free shared buffers cached
Mem: 994 930 63 0 31 809
-/+ buffers/cache: 89 905
Swap: 2047 0 2047
安装到出现如下叫你使用root用户执行以下脚本
/u01/app/product/11.2.0/dbhome_1/root.sh
于是使用另一会话终端执行
[root@aliyun_test ~]# /u01/app/product/11.2.0/dbhome_1/root.sh
Check /u01/app/product/11.2.0/dbhome_1/install/root_aliyun_test_2016-09-20_10-20-22.log for the output of root script
然后回到oracle用户那个终端敲入enter键就安装完成
然后继续修改oracle家目录下的环境文件如下
vim /home/oracle/.bash_profile
export ORACLE_HOME=/u01/app/product/11.2.0/dbhome_1
PATH=${ORACLE_HOME}/bin:$PATH:$HOME/bin
下一步就是配置监听服务，具体操作如下
启动监听
###############modify netca.rsp
cp database/response/netca.rsp /home/oracle/
vim /home/oracle/netca.rsp
GENERAL]
RESPONSEFILE_VERSION="11.2"
CREATE_TYPE="CUSTOM"
INSTALL_TYPE=""custom" "安装的类型("typical—典型","minimal—最小" or "custom—自定义")
LISTENER_NUMBER=1 监听器数量
LISTENER_NAMES={"test"} 监听器的名称列表
LISTENER_PROTOCOLS={"TCP;1521"} 监听器使用的通讯协议列表
LISTENER_START=""test"" 监听器启动的名称
然后运行：
netca /silent /responsefile /home/oracle/netca.rsp
[oracle@aliyun_test app]$ netca /silent /home/oracle/netca.rsp
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /opt/oracle/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Configuring Listener:test
Listener configuration complete.
Oracle Net Listener Startup:
Running Listener Control:
/u01/app/product/11.2.0/dbhome_1/bin/lsnrctl start test
Listener Control complete.
Listener started successfully.
Profile configuration complete.
Oracle Net Services configuration successful. The exit code is 0
监听配置完，端口就会开启，查看一下
[root@aliyun_test ~]# netstat -tunlp|grep 1521
tcp 0 0 0.0.0.0:1521 0.0.0.0:* LISTEN 17760/tnslsnr
/u01/app/product/11.2.0/dbhome_1/bin/tnslsnr test（这条命令启动的）
最后创建单实例数据库
静默建立新库
cp database/response/dbca.rsp /home/oracle/
vim /home/oracle/dbca.rsp
然后修改以下：
[GENERAL]
RESPONSEFILE_VERSION = "11.2.0" //不能更改
OPERATION_TYPE = "createDatabase"
GDBNAME = "test" //全局数据库的名字=SID+主机域名
SID= "test" //对应的实例名字
TEMPLATENAME = "General_Purpose.dbc" //建库用的模板文件
SYSPASSWORD = "redhat" //SYS管理员密码
SYSTEMPASSWORD = "redhat" //SYSTEM管理员密码
DATAFILEDESTINATION = /u01/app/oradata //数据文件存放目录
RECOVERYAREADESTINATION=/u01/app/flash_recovery_area //恢复数据存放目录
CHARACTERSET = "AL32UTF8" //字符集，重要!!! 建库后一般不能更改，所以建库前要确定清楚。(CHARACTERSET = "AL32UTF8"
NATIONALCHARACTERSET= "UTF8")
TOTALMEMORY = "380" //oracle内存
然后静默建库
dbca -silent -responseFile /home/oracle/dbca.rsp
如此之后数据库创建完成，使用sqlplus命令操作，进行登录
登录的用户采用的system密码为redhat，上述操作都有记录
至此静默安装oracle完成
启动监听：
[oracle@oracle admin]$ lsnrctl start test
查看端口1521是否开启
启动数据库：
[oracle@oracle admin]$ sqlplus /nolog
