centos6 安装oracle 11g

红色多瑙河

　　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

$ su -
Password:
root@dabian:~#  
root@dabian:~# xhost +SI:localuser:oracle
localuser:oracle being added to access control list
root@dabian:~# su -oracle　　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
