一、准备安装

　　基本都是按部就班。

　　使用的OS版本：OEL4

以下是引用片段：
　[oracle@ractest orcl]$ cat /etc/redhat-release
　　Enterprise Linux Enterprise Linux AS release 4 (October Update 5)
　　[oracle@ractest orcl]$ cat /etc/enterprise-release
　　Enterprise Linux Enterprise Linux AS release 4 (October Update 5)

　　安装程序路径：

　　/mnt/Oracle11g_linux_x86_64/database

　　创建用户

以下是引用片段：
　　groupadd -g 1001 dba
　　groupadd -g 1002 oinstall
　　useradd -u 10000 -g dba -G oinstall,dba -d /home/oracle -s /bin/bash oracle
　　chown -R oracle:dba /home/oracle
　　usermod -g dba -G oinstall,dba oracle
　　使用的.bash_profile
　　export ORACLE_BASE=/home/oracle
　　export ORACLE_HOME=$ORACLE_BASE/11g
　　export ORA_CRS_HOME=$ORACLE_BASE/crs
　　export ORACLE_PATH=$ORACLE_BASE/common/oracle/sql:.:$ORACLE_HOME/rdbms/admin
　　export ORACLE_SID=orcl1
　　export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:${PATH}:$HOME/bin
　　export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
　　export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin
　　export ORACLE_TERM=xterm
　　export TNS_ADMIN=$ORACLE_HOME/network/admin
　　export ORA_NLS10=$ORACLE_HOME/nls/data
　　export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib:$ORACLE_HOME/oracm/lib:$ORACLE_HOME/lib
　　export LIBPATH=$LIBPATH:$ORA_CRS_HOME/lib:$ORACLE_HOME/lib
　　export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/jlib:$ORACLE_HOME/network/jlib:$ORACLE_HOME/JRE
　　export THREADS_FLAG=native
　　export TEMP=/tmp
　　export TMPDIR=/tmp
　　export NLS_LANG=american_america.WE8ISO8859P1
　　export DISPLAY=10.198.90.55:2
　　alias sysdba="sqlplus /as sysdba"
　　export EDITOR=vi

　　修改的核心参数：

以下是引用片段：
　　kernel.shmall = 2097152
　　kernel.shmmax = 2147483648
　　kernel.shmmni = 4096
　　kernel.sem = 250 32000 100 128
　　fs.file-max = 65536
　　net.ipv4.ip_local_port_range = 1024 65000
　　net.core.rmem_default=262144
　　net.core.wmem_default=262144
　　net.core.rmem_max=262144
　　net.core.wmem_max=262144

　　使用xclock检查display正确：

选择oracle base的时候，oracle不推荐使用user home作为oracle base，这里我选yes忽略

进行prerequirements检查的时候，安装程序认为swap不足，我选择YES忽略

以下是引用片段： [oracle@ractest database]$ [oracle@ractest database]$ su - root Password: [root@ractest ~]# /home/oracle/oraInventory/orainstRoot.sh Changing permissions of /home/oracle/oraInventory to 770.
