1，硬件配置
grep MemTotal /proc/meminfo
uname -m
grep SwapTotal /proc/meminfo
free
df -h /dev/shm/2，内核需求
-
On Red Hat Enterprise Linux 6
2.6.32-71.el6.x86_64 or later
-
On Red Hat Enterprise Linux 7
3.10.0-54.0.1.el7.x86_64 or later
uname -r 内核查看 3，redhat6必须安装的包
binutils-2.20.51.0.2-5.11.el6 (x86_64) compat-libcap1-1.10-1 (x86_64) compat-libstdc++-33-3.2.3-69.el6 (x86_64) compat-libstdc++-33-3.2.3-69.el6.i686 gcc-4.4.4-13.el6 (x86_64) gcc-c++-4.4.4-13.el6 (x86_64) glibc-2.12-1.7.el6 (i686) glibc-2.12-1.7.el6 (x86_64) glibc-devel-2.12-1.7.el6 (x86_64) glibc-devel-2.12-1.7.el6.i686 ksh libgcc-4.4.4-13.el6 (i686) libgcc-4.4.4-13.el6 (x86_64) libstdc++-4.4.4-13.el6 (x86_64) libstdc++-4.4.4-13.el6.i686 libstdc++-devel-4.4.4-13.el6 (x86_64) libstdc++-devel-4.4.4-13.el6.i686 libaio-0.3.107-10.el6 (x86_64) libaio-0.3.107-10.el6.i686 libaio-devel-0.3.107-10.el6 (x86_64) libaio-devel-0.3.107-10.el6.i686 make-3.81-19.el6 sysstat-9.0.4-11.el6 (x86_64)
5，包安装查看
rpm -q package_name 6，create groups and users
oracle不能在root帐户下进行安装，所以需要为oracle的安装专门创建一个用户，同时需要创建dba和oinstall的用户组.
groupadd dba
groupadd oinstall
useradd -g oinstall -G dba oracle
passwd oracle
以下命令将oracle安装目录（/opt/oracle）赋予oracle用户oinstall用户组
[root@localhost oracle]#chown –R oracle:oinstall /opt/oracle
7,Config kernol para
Using any text editor,create or edit the /etc/sysctl.conf file,and add or edit lines similar to the following:
fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 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 = 1048576 生效执行
/sbin/sysctl -p
8,oracle环境变量
设置ORACLE环境变量
修改oracle用户主目录（/home/oracle）的的环境变量配置文件.bash_profile。使用以下命令
[root@localhost oracle]#vi /home/oracle/.bash_profile
往配置文件中加入以下内容 export ORACLE_SID=orcl （注意这个值要和下面创建的数据库实例名称相同） export ORACLE_BASE=/opt/oracle/app export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1 export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
