一、安裝oracle所需要的軟件包（具體根據oracle官方文檔）

可以使用

# yum -y install binutils* compat-lib* gcc-* glibc-* ksh libgcc-* libstdc++-* libaio-* make-* sysstat*

進行安裝。

二、創建用戶組和用戶（root）

# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle

三、配置linux內核參數（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、修改用戶參數（root）

#vi /etc/security/limits.conf
...
oracle           soft    nproc   2047
oracle           hard    nproc   16384
oracle           soft    nofile  1024
oracle           hard    nofile  65536
...

五、創建目錄

mkdir -p /u01/app/

chown -R oracle:oinstall /u01/app/

chmod -R 775 /u01/app/

六、設置環境變量

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、解壓縮

#unzip linux.x64_11gR2_database_1of2.zip 
#unzip linux.x64_11gR2_database_2of2.zip

八、切到oracle用戶，安裝,，會報錯Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<
