2、域名解析设置及网络配置

[root@localhost CentOS]# vi /etc/hosts

127.0.0.1 localhost.localdomain localhost

::1 localhost6.localdomain6localhost6

192.168.56.103 hyl

[root@localhost CentOS]# vi/etc/sysconfig/network-scripts/ifcfg-eth0

# Intel Corporation 82540EM Gigabit Ethernet Controller

DEVICE=eth0

BOOTPROTO=static

IPADDR=192.168.56.103

NETMASK=255.255.255.0

HWADDR=08:00:27:29:DB:B2

ONBOOT=yes

~

~

[root@localhost CentOS]# service network restart

正在关闭接口 eth0： [确定]

关闭环回接口： [确定]

禁用 IPv4 包转送：net.ipv4.ip_forward = 0

[确定]

弹出环回接口： [确定]

弹出界面 eth0： [确定]

[root@localhost CentOS]# vi /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

#HOSTNAME=localhost.localdomain

[root@localhost CentOS]# su -

3、创建用户、组

[root@hyl ~]# groupadd oinstall

[root@hyl ~]# groupadd dba

[root@hyl ~]# useradd -g oinstall -G dba oracle

[root@hyl ~]# passwd oracle

Changingpassword for user oracle.

New UNIXpassword: oracle

BADPASSWORD: it is based on a dictionary word

Retypenew UNIX password: oracle

passwd:all authentication tokens updated successfully.

[root@hyl ~]# id oracle

uid=501(oracle)gid=501(oinstall) groups=501(oinstall),502(dba)

4、配置内核参数、修改环境变量

[root@hyl ~]# vi /etc/sysctl.conf

添加：

kernel.shmall = 4294967296

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65500

net.core.rmem_default = 4194304

net.core.wmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_max = 262144

~

"/etc/sysctl.conf" 43L, 1228C written

[root@hyl ~]# sysctl -p

net.ipv4.ip_forward= 0

net.ipv4.conf.default.rp_filter= 1
