一、安装oracle所需要的软件包（具体根据oracle官方文档）

可以使用

#yum-yinstallbinutils*compat-lib*gcc-*glibc-*kshlibgcc-*libstdc++-*libaio-*make-*sysstat*

进行安装。

二、创建用户组和用户（root）

#groupaddoinstall
#groupadddba
#useradd-goinstall-Gdbaoracle
#passwdoracle

三、配置linux内核参数（root）

#vi/etc/sysctl.conf
...
fs.aio-max-nr=1048576
fs.file-max=6815744
kernel.shmall=2147483648
kernel.shmmax=68719476736
kernel.shmmni=4096
kernel.sem=25032000100128
net.ipv4.ip_local_port_range=900065500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
...
#sysctl-p

四、修改用户参数（root）

#vi/etc/security/limits.conf
...
oraclesoftnproc2047
oraclehardnproc16384
oraclesoftnofile1024
oraclehardnofile65536
...

五、创建目录

mkdir -p /u01/app/

chown -R oracle:oinstall /u01/app/

chmod -R 775 /u01/app/

六、设置环境变量

vi.bash_profile
exportORACLE_BASE=/u01/app/oracle
exportORACLE_HOME=/u01/app/oracle/product/11.2/db_1
exportPATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH
exportORACLE_SID=test
exportLANG="en_US.UTF-8"
exportNLS_LANG=american_AMERICA.UTF8
exportNLS_DATE_FORMAT="YYYY-MM-DDHH24:MI:SS"

七、解压缩

#unziplinux.x64_11gR2_database_1of2.zip
#unziplinux.x64_11gR2_database_2of2.zip

八、切到oracle用户，安装,，会报错Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

#su-oracle

$su-
Password:

root@dabian:~#xhost+SI:localuser:oracle
localuser:oraclebeingaddedtoaccesscontrollist

报错用上面命令解决，将oracle用户添加到 xhost

执行安装命令，进行安装，弹出图形界面

最后执行

#/u01/app/oraInventory/orainstRoot.sh
#/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
