useradd -u 1100 -g oinstall -G asmadmin,asmoper -d /home/grid -s /bin/bash -c "grid Infrastructure Owner" grid
echo "grid" | passwd --stdin grid
useradd -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
echo "oracle" | passwd --stdin oracle
修改用户的组信息：要不以后找不到ASM组：
[[email?protected] bin]# usermod -a -G dba,asmadmin oracle
4. 配置 grid 和 oracle 用户的配置文件
mkdir -p /u01/app/oracle
mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01
----------Oracle User----------
文件是：vi /home/oracle/.bash_profile
export PS1="`/bin/hostname -s`-> "
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=baydb1
export ORACLE_UNQNAME=baydb
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export EDITOR=vi

umask 022
生效：
#source .bash_profile
----------GRID User----------

export PS1="`/bin/hostname -s`-> "
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM1

[[email?protected] ~]$ vi /etc/security/limits.conf
在文件最下方输入以下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
[[email?protected] ~]$ vi /etc/pam.d/login
在文件最下方输入以下内容：
session required /lib64/security/pam_limits.so
#session required /lib/security/pam_limits.so
session required pam_limits.so
注意：因为是64位的系统，所以一定要写/lib64/security/pam_limits.so
如果写成/lib/security/pam_limits.so（这是32位系统的设置），就会在虚拟机本地的字符界面模式下无法
登录
[[email?protected] ~]$ vi /etc/profile
if [ $USER = "oracle" ]||[ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
[[email?protected]]# vi /etc/sysctl.conf
将下列内容加入该文件：
fs.aio-max-nr = 12019/4/17048576
fs.file-max = 6815744
kernel.shmall = 8160280
kernel.shmmax = 33424509440
kernel.shmmni = 4096
kernel.sem =250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304
【使内核参数立即生效】
[[email?protected] ~]#sysctl -p
=================================================================
三、停止ntp服务，11gR2新增的检查项，配置集群时间同步服务
[[email?protected] ~]# service ntpd status
[[email?protected] ~] #service ntpd stop
[[email?protected] ~] #chkconfig –level 2345 ntpd off
[[email?protected] ~] #rm –rf /etc/ntp.conf
节点二和节点三上执行相同的命令，卸载NTP
在集群安装完后，要确认ctssd是否处于活动状态
[[email?protected] ~] #crsctl check ctss
问题1：
[[email?protected] ~]# iscsiadm -m discovery -t st -p 192.168.0.10 ##用iscsiadm探测openfiler新添加的iscsi共享卷
-bash: iscsiadm: command not found
[[email?protected] ~]# mount /dev/cdrom /media --加载光盘，安装iscsi-initiator rpm包
解决：
[[email?protected] Packages]# pwd
/mnt/cdrom/Packages
[[email?protected] Packages]# yum install iscsi* #iscsi-initiator-utils-6.2.0.868-0.18.el5.i386.rpm
[[email?protected]~] # rpm –ivh scsi-target-utils*.rpm
// RedHat 6在光盘Packages目录下
// RedHat 5在光盘ClusterStorage目录下 （编辑：宣城站长网）
