使用yum安装Oracle12C依赖，标注32 bit不需安装。没有yum环境的这些包可以在操作系统安装介质中查找。这些需要的安装依赖包可以在Oracle提供的12C在线安装文档中找到。操作系统版本不同，所需要的依赖包略有差别。

[root@edu ~]# groupadd oinstall [root@edu ~]# groupadd dba [root@edu ~]# useradd -g oinstall -G dba oracle [root@edu ~]# 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.
使用vi命令修改配置文件/etc/sysctl.conf,使用/sbin/sysctl –p命令使内核配置生效。
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
使用vi命令修改配置文件/etc/security/limits.conf
oracle soft nofile 65536 oracle hard nofile 65536 oracle soft nproc 16384 oracle hard nproc 16384 oracle stack nproc 16384
[root@edu ~]# mkdir -p /u01/app [root@edu ~]# chown -R oracle:oinstall /u01 [root@edu ~]# chmod -R 775 /u01 [root@edu ~]# ls -ld /u01/app/ drwxrwxr-x 2 oracle oinstall 4096 Jan 29 20:54 /u01/app/ [root@edu ~]#
修改Oracle下的.bash_profile文件，不同的shell名称会有区别。source .bash_profile使修改生效。
ORACLE_BASE=/u01/app;export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1 export ORACLE_HOME ORACLE_SID=ORCL;export ORACLE_SID TMP=/tmp;export TMP TMPDIR=/tmp;export TMPDIR PATH=$PATH:$ORACLE_HOME/bin;export PATH DISPLAY=:0.0;export DISPLAY
按照提示以root身份执行以下脚本：
[root@edu /]# /u01/oraInventory/orainstRoot.sh Changing permissions of /u01/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world. Changing groupname of /u01/oraInventory to oinstall. The execution of the script is complete.
[root@edu /]# /u01/app/product/12.1.0/dbhome_1/root.sh Performing root user operation for Oracle 12c The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /u01/app/product/12.1.0/dbhome_1 Enter the full pathname of the local bin directory: [/usr/local/bin]: Copying dbhome to /usr/local/bin ... Copying oraenv to /usr/local/bin ... Copying coraenv to /usr/local/bin ... Creating /etc/oratab file... Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root script. Now product-specific root actions will be performed.
在Oracle用户下直接执行dbca命令：

至此我们的Oracle12c数据库安装成功！
