linux下cpio.gz文件的解压方法linux解压cpiocpio.gz
今天下载了 10201_database_linux_x86_64.cpio.gz 文件，解压方法如下：
1. gunzip 10201_database_linux_x86_64.cpio.gz
得到10201_database_linux_x86_64.cpio文件
2. cpio -idmv <10201_database_linux_x86_64.cpio
即可在当前目录下解压出来

第三步、配置Linux系统环境和oracle用户环境变量
对于Oracle软件在Linux 5系统下的安装，需要用户提前在Linux系统下做一些配置，从而满足安装Oracle软件的基本需求。
以下0、1、2、3、4步使用root用户，第5和6步使用分别使用grid用户和oracle用户
0.要配置/etc/hosts 添加ip地址、 主机，否则grid的netca配置的时候会报错。
[root@instuctor ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.60 student
1.创建oracle用户和组
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper
/usr/sbin/groupadd -g 504 asmadmin
/usr/sbin/groupadd -g 505 asmoper
/usr/sbin/groupadd -g 506 asmdba
/usr/sbin/useradd -g oinstall -G dba,asmdba,oper oracle
/usr/sbin/useradd -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid
passwd grid
passwd oracle
2.创建安装grid软件和oracle软件的目录，并授予相应的权限
mkdir -p /u01/app/oracle/product/11.2.0/db
mkdir -p /u01/app/grid/product/11.2.0/grid
chown -R oracle:oinstall /u01/app/
chown -R grid:oinstall /u01/app/grid
chmod -R 775 /u01/
3.配置系统文件和进程限制，配置内核参数
cat >> /etc/security/limits.conf <<EOF
#ORACLE SETTING
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
EOF
cat >>/etc/pam.d/login<<EOF
#ORACLE SETTING
session required pam_limits.so
EOF
cat >>/etc/sysctl.conf<<EOF
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
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
EOF
使配置的内核参数生效，使用sysctl -p命令
sysctl -p
4.关闭NTP服务和删除NTP配置文件
grid时间同步所需要的设置
Network Time Protocol Setting
/sbin/service ntpd stop
chkconfig ntpd off
rm /etc/ntp.conf
or, mv /etc/ntp.conf to /etc/ntp.conf.org.
5.用户grid的环境变量的设置
grid 用户配置文件 ORACLE_HOSTNAME请自行设置,这个配置使用grid用户
#su - grid
$vi .bash_profile
export LD_ASSUME_KERNEL=2.6.18
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=student
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/grid
export ORACLE_SID=+ASM
export ORACLE_TERM=xterm
export PATH=$PATH:$ORACLE_HOME/bin
umask 022
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
使用source命令是环境变量生效
source .bash_profile
6.用户oracle的环境变量的设置
oracle用户配置文件 ORACLE_HOSTNAME请自行设置,这个配置使用oacle用户
#su - oracle
$vi .bash_profile
# Oracle Settings oracle
export LD_ASSUME_KERNEL=2.6.18
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=student
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db
export ORACLE_SID=db01
export ORACLE_TERM=xterm
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export PATH=/usr/sbin:$PATH
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
使用source使环境变量立即生效
source .bash_profile
第四步、安装和配置ASM
关闭虚拟机，添加硬盘sdb、sdc和sdd，大小都是3G，启动虚拟机，使用fdisk对添加的硬盘分区，使用wincp上传相应内核的asmlib软件到服务器，并安装
