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 -y install binutils* compat-lib* gcc-* glibc-* ksh libgcc-* libstdc++-* libaio-* make-* sysstat*
进行安装。
二、创建用户组和用户（root）
# groupadd oinstall # groupadd dba # useradd -g oinstall -G dba oracle # passwd oracle
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 = 250 32000 100 128 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 = 1048586 ... #sysctl -p
四、修改用户参数（root）
#vi /etc/security/limits.conf ... oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 ...
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 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=/u01/app/oracle/product/11.2/db_1 export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH export ORACLE_SID=test export LANG="en_US.UTF-8" export NLS_LANG=american_AMERICA.UTF8 export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
七、解压缩
#unzip linux.x64_11gR2_database_1of2.zip #unzip linux.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 $cd /opt/database $ ./runInstaller Starting Oracle Universal Installer... Checking Temp space: must be greater than 120 MB.

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
