中标麒麟6.0_安装DM7_OS准备(二)

上一章节介绍了如何安装中标麒麟6.0操作系统；
本章节主要简介在安装DM7之前，如何配置操作系统环境；

1.收集操作系统信息

[root@localhost ~]# lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch:graphics-4.1-amd64:graphics-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: NeoKylinAdvancedServer
Description:    NeoKylin Linux Advanced Server release 6.0  (Dhaulagiri) 
Release:        6.0
Codename:       Dhaulagiri

2.安装必要包

2.1.本地yum源

[root@localhost ~]# mkdir /mnt/cdrom
[root@localhost ~]# mount -t iso9660 /dev/sr0 /mnt/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# mv ns6-adv.repo ns6-adv.repo.bak
[root@localhost yum.repos.d]# vi localyum.repo 
[zbql6.0]
name=zbql6.0
baseurl=file:///mnt/cdrom/
enabled=1
gpgcheck=0

[root@localhost ~]# yum makecache
[root@localhost ~]# yum repolist;

2.2.安装glibc

[root@localhost ~]# rpm -qa |grep glibc
glibc-common-2.12-1.25.el6.ns6.01.x86_64
glibc-2.12-1.25.el6.ns6.01.x86_64

--需安装
[root@localhost ~]# yum -y install glibc-headers
[root@localhost ~]# yum -y install glibc-2.12-1.25.el6.ns6.01.i686
[root@localhost ~]# yum -y install compat-glibc
[root@localhost ~]# yum -y install glibc-devel
[root@localhost ~]# yum -y install glibc-utils

--检查
[root@localhost ~]# rpm -qa |grep glibc
glibc-devel-2.12-1.25.el6.ns6.01.x86_64
glibc-headers-2.12-1.25.el6.ns6.01.x86_64
glibc-utils-2.12-1.25.el6.ns6.01.x86_64
glibc-common-2.12-1.25.el6.ns6.01.x86_64
compat-glibc-headers-2.5-46.2.ns6.01.x86_64
glibc-2.12-1.25.el6.ns6.01.i686
glibc-2.12-1.25.el6.ns6.01.x86_64
compat-glibc-2.5-46.2.ns6.01.x86_64

3.硬件信息

3.1.查看CPU

[root@localhost ~]# cat /proc/cpuinfo

3.2.内存

[root@localhost ~]# free -m
             total       used       free     shared    buffers     cached
Mem:          3947       1405       2541          0         45       1017

Swap:         4095          0       4095

3.3.磁盘信息

[root@localhost ~]# fdisk -l

Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000a99a5

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          26      204800   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              26         548     4194304   82  Linux swap / Solaris

/dev/sda5             679        5222    36493312   83  Linux

3.4.查看空间大小

[root@localhost ~]# df -h
文件系统              容量  已用  可用 已用%% 挂载点
/dev/sda5              35G  3.2G   30G  10% /
tmpfs                 2.0G  100K  2.0G   1% /dev/shm
/dev/sda1             194M   42M  143M  23% /boot
/dev/sda3            1008M  248M  709M  26% /tmp
/dev/sr0              4.3G  4.3G     0 100% /media/NeoKylin Linux Advanced Server 6
/dev/sr0              4.3G  4.3G     0 100% /mnt/cdrom

4.用户和组（dinstall、dmdba）

[root@localhost ~]# id dmdba
id: dmdba：无此用户

[root@localhost ~]# groupadd dinstall
[root@localhost ~]# useradd -g dinstall dmdba
[root@localhost ~]# passwd dmdba 
[root@localhost ~]# id dmdba
uid=500(dmdba) gid=501(dinstall) 组=501(dinstall)

5.创建安装目录 /dm7

[root@localhost ~]# mkdir /dm7
[root@localhost ~]# chown -R dmdba:dinstall /dm7

6.配置环境变量

[root@localhost ~]# su - dmdba

[dmdba@localhost ~]$ vi .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export DM_HOME=/dm7
export PATH=$DM_HOME/bin:$DM_HOME/tool:$PATH:$HOME/bin

[dmdba@localhost ~]$ source .bash_profile 
[dmdba@localhost ~]$ echo $DM_HOME
/dm7

7.设置文件最大打开数目

--方式1（临时）
[root@localhost ~]# ulimit -n 65536

--方式2（永久）
[root@localhost ~]# vi /etc/security/limits.conf
dmdba soft nofile 65536
dmdba hard nofile 65536

8.关闭selinux和防火墙

[root@localhost ~]# vi /etc/selinux/config
SELINUX=disabled
[root@localhost ~]# service iptables stop
[root@localhost ~]# chkconfig iptables off

9.修改主机名

[root@localhost ~]# vi /etc/sysconfig/network
HOSTNAME=dm7

10.重启主机

[root@localhost ~]# shutdown -r now
