规划：
1、IP规划
127.0.0.1 localhost.localdomain localhost
119.23.147.63 shardcat
119.23.134.20 shardnode1
119.23.134.28 shardnode2
2、磁盘规划
+CRS 三个10G的盘
+DGDATA 4个200G的盘
+ARCH 1个200G






1、创建用户和组
/usr/sbin/groupadd -g 1001 oinstall
/usr/sbin/groupadd -g 1002 dba
/usr/sbin/groupadd -g 1003 oper
/usr/sbin/useradd -u 1001 -g oinstall -G dba,oper -m oracle
echo nihao123, |passwd --stdin oracle
2、创建文件夹
mkdir -p /oracle/app/
chown -R oracle:oinstall /oracle/app/
chmod -R 775 /oracle/app/
mkdir -p /oracle/app/oraInventory
chown -R oracle:oinstall /oracle/app/oraInventory
chmod -R 775 /oracle/app/oraInventory
mkdir -p /oracle/app/oracle
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle/app/oracle
3、编辑.bash_profile
#for grid
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM1
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=/oracle/app/grid/product/11.2.0/grid
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"
export THREADS_FLAG=native
export PATH=$ORACLE_HOME/bin:$PATH
export THREADS_FLAG=native
export PATH=$ORACLE_HOME/bin:$PATH
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
alias gsm_env='. /home/oracle/gsm_env'
alias db_env='. /home/oracle/db_env'
==
gsm_env
export ORACLE_HOME=$GSM_HOME
export PATH=$ORACLE_HOME/bin
db_env
export ORACLE_HOME=$DB_HOME
export PATH=$ORACLE_HOME/bin
4、修改系统参数
vi /etc/security/limits.conf
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 10240
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 10240
=========================

net.core.wmem_default        = 1048576
net.core.wmem_max            = 1048576
==============================================
设置vnc
 yum install -y tigervnc-server
 
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:3.service
vi /etc/systemd/system/vncserver@:3.service
