1、安装依赖包

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) libXext-1.1 (x86_64) libXext-1.1 (i686) libXtst-1.0.99.2 (x86_64) libXtst-1.0.99.2 (i686) libX11-1.3 (x86_64) libX11-1.3 (i686) libXau-1.0.5 (x86_64) libXau-1.0.5 (i686) libxcb-1.5 (x86_64) libxcb-1.5 (i686) libXi-1.3 (x86_64) libXi-1.3 (i686) make-3.81-19.el6 sysstat-9.0.4-11.el6 (x86_64)

2、创建oracle用户和组

[root@ora12c Server]# groupadd oinstall[root@ora12c Server]# groupadd dba[root@ora12c Server]# useradd -g oinstall -G dba oracle[root@ora12c Server]# passwd oracle Changing password for user oracle.

New UNIX password:BAD PASSWORD: it is based on a dictionary word Retype new UNIX password:passwd: all authentication tokens updated successfully.

[root@ora12c Server]# mkdir -p /oracle/[root@ora12c Server]# chown -R oracle:oinstall /oracle/[root@ora12c Server]# chmod -R 775 /oracle/

4、修改内核参数

在/etc/sysctl.conf文件下加入如下参数[root@ora12c Server]# vim /etc/sysctl.conf fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 2536870912 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/sbin/sysctl -p 使参数生效[root@ora12c Server]# /sbin/sysctl -p 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 = 1048586 net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 2 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296注意：kernel.shmmax一般为物理内存的一半，SGA大小不能超过这个值，否则报错

5、修改用户限制

在/etc/security/limits.conf加入相关配置[root@ora12c Server]# vim /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 oracle hard stack 10240修改文件/etc/pam.d/login，增加以下内容：session required pam_limits.so

6、配置环境变量

在 .bash_profile配置如下变量oracle@ora12c ~]$ vim .bash_profile export ORACLE_BASE=/oracle/ora12c export ORACLE_HOME=$ORACLE_BASE/db1 export ORACLE_SID=ora12c export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS";export PATH=$ORACLE_BASE/bin:$ORACLE_HOME/bin:/bin:/sbin:/usr/ccs/bin:/usr/local/bin:$PATH umask 022使配置文件生效[oracle@ora12c ~]$ source .bash_profile后面的安装就是使用xmanager进行图形界面安装，根据界面提示一步步来就可以了。
