make-3.81-19.el6
sysstat-9.0.4-11.el6 (x86_64)
compat-libcap1-1.10-1 (x86_64)
compat-libstdc++-33-3.2.3-69.el6 (x86_64)
gcc-4.4.4-13.el6 (x86_64)
gcc-c++-4.4.4-13.el6 (x86_64)
glibc-devel-2.12-1.7.el6 (x86_64)
ksh <== 任何版本的 ksh 都可以。
libstdc++-devel-4.4.4-13.el6 (x86_64)
libaio-devel-0.3.107-10.el6 (x86_64)
compat-libstdc++-33-3.2.3-69.el6 (i686)
glibc-2.12-1.7.el6 (i686)
glibc-devel-2.12-1.7.el6 (i686)
libgcc-4.4.4-13.el6 (i686)
libstdc++-4.4.4-13.el6 (i686)
libstdc++-devel-4.4.4-13.el6 (i686)
libaio-0.3.107-10.el6 (i686)
libaio-devel-0.3.107-10.el6 (i686)
libXext-1.1 (i686)
libXtst-1.0.99.2 (i686)
libX11-1.3 (i686)
libXau-1.0.5 (i686)
libxcb-1.5 (i686)
libXi-1.3 (i686)
这里建议配置好YUM，用yum 来一次安装。
1.2 修改内核参数/etc/sysctl.conf
在sysctl.conf 中加入以下内容：
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
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
kernel.panic_on_oops = 30
如下2个参数直接使用默认值即可：
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
用root用户执行sysctl -p 使修改生效。
1.3 设置 Oracle 用户的Shell 限制
在 /etc/security/limits.conf中添加如下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
注：limits.conf 文件发生更改时，这些更改立即生效。但是，如果 Oracle 用户已登录，则这些更改将在注销这些用户并重新登录之后生效。必须先完成此操作，然后再使用这些帐户进行安装。
1.4 设置PAM
确保加载了最新版本的 PAM，然后在 /etc/pam.d/login 文件中添加或编辑以下行：
session required pam_limits.so
1.5 设置ulimit
验证当前 ulimit，如果需要则增大。可以采用多种方式完成此操作，推荐方法是在 /etc/profile 中添加以下行：
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
1.6 创建Oracle用户和组
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba oracle
passwd oracle
1.7 创建目录
mkdir -p /u01/app/oracle/product/12.1.0/db_1
chown -R oracle.oinstall /u01
chmod -R 777 /u01
1.8 设置oracle用户的环境变量
修改/home/oracle/.bash_profile 文件添加如下内容：
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1; export ORACLE_HOME
ORACLE_SID=dave; export ORACLE_SID
SHLIB_PATH=$LD_LIBRARY_PATH;export SHLIB_PATH
NLS_LANG=American_America.zhs16gbk;export NLS_LANG
ORA_NLS10=$ORACLE_HOME/nls/data;export ORA_NLS10
TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;export CLASSPATH
Source 参数使生效：
[[email protected] ~]$ source ~/.bash_profile
二．开始安装
运行runinstaller。
[[email protected] database]#/u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
Changing groupname of /u01/app/oraInventory tooinstall.
The execution of the script is complete.
[[email protected] database]#/u01/app/oracle/product/12.1.0/db_1/root.sh
Performing root user operation for Oracle 12c
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/12.1.0/db_1
Enter the full pathname of the local bin directory:[/usr/local/bin]:
Copyingdbhome to /usr/local/bin ...
Copyingoraenv to /usr/local/bin ...
Copyingcoraenv to /usr/local/bin ...
Creating /etc/oratab file...
Entries will be added to the /etc/oratab file asneeded by
Database Configuration Assistant when a database iscreated
Finished running generic part of root script.
Now product-specific root actions will beperformed.
