[root@localhost ~]# cd /dev
[root@localhost dev]# ls
[root@localhost dev]# fdisk /dev/sdb
[root@localhost dev]# mkfs -t xfs /dev/sdb1

2. Create a directory orc

[root@localhost dev]# mkdir /orc

3. Modify the host name

[root@localhost ~]# vim /etc/hostname
#末行添加以下内容
HOSTNAME=oracle

4. Modify the domain name resolution

[root@localhost ~]# vim /etc/hosts
#末行添加以下内容

5. Mount the new hard disk to the orc directory

[root@oracle ~]# mount /dev/sdb1 /orc

6. Environmental download package

[root@oracle ~]# yum -y install binutils compat-libcapl compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel

7. Modify the configuration file sysctl.conf

[root@oracle ~]# vim /etc/sysctl.conf
#末行添加以下内容
fs.aio-max-nr = 1048576
#异步Io请求数目推荐值是: 1048576 其实它等于1024*1024 也就是1024K个
fs.file-max = 6815744
##打开的文件句柄的最大数量,防止文件描述符耗尽的问题
kernel.shmall = 2097152
##共享内存总量页为单位，内存除以4K所得
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
##SEMMSL: 每个信号集的最大信号数量SEMMNS: 用于控制整个Linux 系统中信号的最大数SEMOPM内核参数用于控制每个semop系统调用可以执行的信号操作的数量SEMMNI:内核参数用于控制整>个Linux 系统中信号集的最大数量
net.ipv4.ip_local_port_range = 9000 65500
##用于向外连接的端口范围
net.core.rmem_default = 262144 
#套接字接收缓冲区大小的缺省值
net.core. rmem_max = 4194304
##套接字接收缓冲区大小的最大值
net.core. wmem_default = 262144 
##套接字发送缓冲区大小的缺省值
net.core. wmem_max = 1048576
#套接字发送缓冲区大小的最大值

8. reload the configuration file

[root@oracle ~]#  sysctl -p

9. User Environment Configuration
