(2) 安装相关包
# rpm -ivh compat-db-4.6.21-15.el6.x86_64.rpm compat-db42-4.2.52-15.el6.x86_64.rpm compat-db43-4.3.29-15.el6.x86_64.rpm

(3) 替换sqlplus工具
# tar zxvf rlwrap-0.37.tar.gz
# cd rlwrap-0.36
# ./configure
# make
# make check
# make install
0-1. 创建oracle安装相关用户组及用户帐号
1）创建oinstall,dba组和oracle用户(用root身份)
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
passwd oracle
2）创建Oralce HOME目录
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chmod -R 775 /u01/app
chown -R oracle:oinstall /u01
1. 修改内核支持
# vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
加载后报错 sysctl -p-----解决方法
error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key
3个参数依赖于bridge模块，该模块如果没有加载则会现上面的输出错误 ------参数不明白……
加载模块即可解决
modprobe bridge
lsmod|grep bridge
在重新加载 sysctl -p
2. 修改文件描述符
cat >> /etc/security/limits.conf << EOF
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
EOF
3. 修改登陆认证模块
cat >> /etc/pam.d/login << EOF
session required /lib64/security/pam_limits.so
EOF
4. 修改本地hosts文件
# vi /etc/hosts
192.168.31.19 hostname
5. 修改Oracle用户环境变量
(1) 配置系统环境变量，加入到最后。
cat >> /etc/profile << EOF
if [ \$USER = "oracle" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
EOF
(2) 配置oracle环境变量
# su - oracle
cat >> /home/oracle/.bash_profile << EOF
export EDITOR=vi
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=orcl
export PATH=\$ORACLE_HOME/bin:\$PATH
export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK"
export LANG=en_US
export LC_ALL=en_US
export LD_LIBRARY_PATH=/lib:/usr/lib:\$ORACLE_HOME/lib
export CLASSPATH=\$ORACLE_HOME/JRE:\$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
alias sqlplus="rlwrap sqlplus"
alias rman="rlwrap rman"
umask 022
EOF
重新加载 source .bash_profile
6.解压数据库
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip
chmod -R 777 /tool/database
7.安装Oracle 11G数据库--------重启服务器 init6 或者 reboot
cd /tool/database
./runInstaller
去掉I wish to receive security updates via My Oracle Surrport选项，点击Next。
选择Install database software only，点击Next。
选择Single instance database installation，点击Next。
在Available Languages中点选English、Simplified Chinese、Traditional Chinese，点击两个框中间的>，
将选中的语言加入到右边的Selected Languages中，然后点击Next。
按照实际情况，选择企业版本，如下图
填写Oracle的软件路径和基本路径，如下图：
选择安装日志目录，如下图所示：
继续下一步安装操作
可以忽略，因为CentOS版本较高，所以11g check的时候不识别高版本lib包
继续安装
安装中，这个时间比较漫长
需要等待中，大概20分钟左右
点击OK，继续
然后点击close，结束
最后要在root执行以下两条脚本
# /u01/app/oraInventory/orainstRoot.sh
# /u01/app/oracle/product/11.2.0/db_1/root.sh
8. 创建数据库
$ dbca
# 选择gernel purpose，在SID和全局名称中，选择你在.bash_profile中创建的SID.
# 数据库的字符集选项中选择ZHS16GBK, 其它默认OK,完成.
Database Configuration Assistant图形界面启动。标题同时指明了步骤的编号和步骤的名称。在步骤名称为Welcome的
欢迎窗口，直接点击next。
等待下一步NEXT
选择Custom Database
，Global Database Name框：输入前面确定的数据库名SID框：自动出现和数据库名相同的内容作为数据库实例名，
单实例情况下不作改动
继续默认
Database Credentials
Use Different Administrative Passwords表格的Password和Confirm Password列中分别为User Name列
SYS、SYSTEM、DBSNMP和SYSMAN用户输入口令并重复一次输入（如密码设置过于简单，下一步前会有
弹出窗口提示确认接受安全风险）sys和system密码设置可以在数据库建立后修改。
密码为HanZheng.123
Database File LocationsStorage Locations：选择Use Common Location for All Database FilesDatabase File Location
框：输入/Oracle/data_ora
Recovery ConfigurationSpecify Fast Recovery Area如果前面Management Options步骤选择了自动备份，
则保留勾选，并在下方：Fast Recovery Area框：修改为快速恢复区的目录名Fast Recovery Area Size框：
调整快速恢复区的大小
Enable Archiving根据是否归档日志的实际需求决定是否选择（重要的生产系统必须打开归档，测试系统一般关闭归
档节省服务器空间）点击旁边的Edit Archive Mode Parameters…，在弹出窗口中：Automatic Archiving：保持默认
勾选Archive Log File Format框：修改为%t_%s_%r.arcArchive Log Destinations表格：第一行中输入
/Oracle/data_ora/archive点击OK返回主窗口Database ContentDatabase Components页面
Initialization Parameters，内存分配20%（测试库所以分小一些，生产库可以分配较大的比如40%60%等），
字符集选择兼容utf8的选项
点击File Location Variables，里面可以看到一些基础参数信息，返回，然后直接下一步，如下图所示：
选择Generate Database Creation Scripts，默认为 /oracle/app/oracle/admin/powerdes/scripts，如下图：
点击OK按钮，有报错说/etc/oratab读取错误，报错如下图所示
所以去建立下这个目录
[root@powerlong4 rpms]# mkdir /etc/oratab
[root@powerlong4 rpms]# chown -R Oracle.oinstall /etc/oratab
之后点击OK按钮，开始创建数据库，如下图所示：
等待35分钟后，数据库创建完毕，之后点击，如下所示：
su - oracle
$ netca # 参数一律默认即可
$ ps -ef |grep ora_
启动Oracle数据库----------------sqlplus登录到数据库
[oracle@hostname ]$ sqlplus / as sysdba 登陆oracle
SQL> startup //起动数据库
起动监听服务
[oracle@hostname ]$ cd $ORACLE_HOME/bin //进入oracle安装目录
[oracle@hostname bin]$ lsnrctl start //起动监听
9，验证数据库
[oracle@powerlong4 ~]$ sqlplus "/ as sysdba"
