OS：RHEL7.2
ORACLE 12C
step1：安装必需的rpm包
yum install binutils libX11 compat-libcap1 libXau compat-libstdc++-33 libaio gcc libaio-devel gcc-c++ libdmx glibc-devel glibc ksh make libgcc sysstat libstdc++ xorg-x11-utils libstdc++-devel xorg-x11-xauth libXext libXv libXtst libXi libxcb libXt libXmu libXxf86misc libXxf86dga libXxf86vm nfs-utils smartmontools
step2：修改内核参数
vim /etc/sysctl.d/98-oracle-kernel.conf
vm.swappiness = 1
vm.dirty_background_ratio = 3
vm.dirty_ratio = 80
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
kernel.sem = 250 32000 100 128
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.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 8589934590 ==8G，大于SGA即可
kernel.shmall = 2147483648 ==8G
kernel.shmmni = 4096
sysctl -p /etc/sysctl.d/98-oracle-kernel.conf
step3：设置用户限制
vim /etc/security/limits.d/99-grid-oracle-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 32768
step4：添加用户
groupadd --gid 54321 oinstall
groupadd --gid 54322 dba
groupadd --gid 54326 oper
groupadd --gid 54327 backupdba
groupadd --gid 54328 dgdba
groupadd --gid 54329 kmdba
useradd --uid 54321 --gid oinstall --groups dba,oper,backupdba,dgdba,kmdba oracle
echo "oracle"|passwd --stdin oracle
step5：设置目录
mkdir -p /u01/app/12.2.0/grid
chown -R oracle.oinstall /u01
chmod -R 755 /u01
step6：设置环境变量
su - oracle
vim .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH;
step7：开始安装
su - root
xhost +
su - oracle
[oracle@oracle12c database]$ ./runInstaller

DISPLAY not set. Please set the DISPLAY and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh: % setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash: $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:
% xhost +
To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':
%
If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/X11R6/bin/xclock
之后尝试设置了多次$DISPLAY，都不行，如下
DISPLAY=192.168.107.155:0.0;export $DISPLAY
DISPLAY=192.168.107.155:1.0;export $DISPLAY
DISPLAY=192.168.107.155:0.1export $DISPLAY
DISPLAY=:0;export $DISPLAY
DISPLAY=:1;export $DISPLAY
之后我在root的一个窗口执行xclock，发现没有clock，之后安装了xorg-x11-apps(yum install xorg-x11-apps)，使用root的xclock就可以看到clock了
之后su - oracle还是看不到clock
之后到root窗口echo $DISPLAY发现是:0，所以我在oracle窗口也设置
DISPLAY=:0;export $DISPLAY
之后就可以正常的图形化安装了
安装过程截图：
这里用fix来修复一下
忽略swap报警，我这里只给swap分了1G
step8：DBCA建库
在这里你可以选择典型配置，也可以选择自定义配置，我选择的是自定义(advanced configuration)
创建listner，叫listner1
给SGA分6G，pga 500M，这是测试库，就我一个人用
