\#创建用户组以及用户  
groupadd -g 1000 oinstall  
groupadd -g 1001 dba  
groupadd -g 1002 oper  
useradd  -u 1003 -g oinstall -G dba,oper oracle  
useradd  -u 1004 -g oinstall -G dba,oper grid  
  
  
\#创建安装目录  
mkdir -p /u01/oracle/db  
mkdir -p /u01/grid/product  
chown -R oracle:oinstall /u01  
chown -R grid:oinstall /u01/grid  
mkdir -p /u01/crs  
chown -R grid:oinstall /u01/crs  
chmod 775 /u01  
  
  
\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#配置系统参数  
\#1.编辑 /etc/sysctl.conf 文件将以下内容添加到文件中  
\#kernel.shmmax指的是单个共享内存段的最大尺寸。建议设置shmmax>= SGA\_MAX\_SIZE 如下60g  
\#kernel.shmall指参数是控制共享内存页数 。Linux共享内存页大小为4KB,如60G/4k  
cat >> /etc/sysctl.conf << EOF  
fs.aio-max-nr = 1048576  
fs.file-max = 6815744  
kernel.shmall = 15728640  
kernel.shmmax = 64424509440  
kernel.shmmni = 4096  
kernel.sem = 1000 128000 100 128  
net.core.rmem\_default = 262144  
net.core.rmem\_max = 4194304  
net.core.wmem\_default = 262144  
net.core.wmem\_max = 1048586  
net.ipv4.ip\_local\_range = 9000  65500  
net.ipv4.ip\_local\_port\_range = 9000  65500  
EOF  
  
  
\#2.编完后必须使你刚才的设置生效，在终端输入以下命令  
/sbin/sysctl  -p  
  
  
\#3.编辑 /etc/profile 在末尾加入以下内容  
cat >> /etc/profile << EOF  
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  
EOF  
  
  
\#4.修改用户验证选项.编辑 /etc/pam.d/login 在末尾加上以下内容  
cat >> /etc/pam.d/login << EOF  
session  required  /lib64/security/pam\_limits.so  
session  required  pam\_limits.so  
EOF  
  
  
\#5.设置Shell Limits(系统资源限制),提高软件的运行效率.编辑 /etc/security/limits.conf,在末尾加上  
cat >> /etc/security/limits.conf << EOF  
oracle  soft  nproc   2047  
oracle  hard  nproc   16384  
oracle  soft  nofile  1024

\#切换到grid用户 编辑/home/grid/.bash\_profile 对于grid而言oracle\_home不能是oracle\_base的子目录  
TMP=/tmp; export TMP  
TMPDIR=$TMP; export TMPDIR  
ORACLE\_SID=+ASM1; export ORACLE\_SID  
\#ORACLE\_SID=+ASM2; export ORACLE\_SID  
ORACLE\_BASE=/u01/crs; export ORACLE\_BASE
