#? 1

执行完tzselect命令选择时区后，时区并没有更改，只是在命令最后提示你可以执行
TZ='Asia/Shanghai'; export TZ

修改时区配置文件
vi /etc/sysconfig/clock
ZONE="Asia/Shanghai"

链接到上海时区
rm -rf /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
/usr/share/zoneinfo/Europe/London

查看时区已经更改
cat /etc/sysconfig/clock
The time zone of the system is defined by the contents of /etc/localtime.
This file is only for evaluation by system-config-date, do not rely on its
contents elsewhere.
ZONE="Asia/Shanghai"

ntp服务器联网同步

美国时间同步服务器 ntpdate time.nist.gov

中国国家授时中心 ntpdate 210.72.145.44

NTP服务器(上海) ntpdate ntp.api.bz

复旦 ntpdate ntp.fudan.edu.cn

微软公司授时主机(美国) ntpdate time.windows.com

台警大授时中心(台湾) ntpdate asia.pool.ntp.org

如果提示报错no server suitable for synchronization found

解决方法添加-u参数可以越过防火墙与主机同步

比如 ntpdate -u 210.72.145.44

date 时间查看

重启服务器测试更改结果
reboot 或者 init6

2, 部署samba

查看是否安装samba
rpm -qa | grep samba
+++++++++++++++++++++++++++++++++++++++++++++
samba-3.6.23-35.el6_8.x86_64
samba-winbind-clients-3.6.23-35.el6_8.x86_64
samba-client-3.6.23-35.el6_8.x86_64
samba4-libs-4.0.0-58.el6.rc4.x86_64
samba-common-3.6.23-35.el6_8.x86_64
samba-winbind-3.6.23-35.el6_8.x86_64
+++++++++++++++++++++++++++++++++++++++++++++

没有安装 yum install samba -y

创建共享目录
mkdir /home/share

赋予目录权限
chmod 777 /home/share

配置访问
vi /etc/samba/smb.conf

# near line 58: add follows
unix charset = UTF-8

# line 75: change (Windows' default)
workgroup = WORKGROUP

# line 81: uncomment and change IP address you allow
hosts allow = 127. 10.0.0.

# line 102: change (no auth)
security = share

# add follows to the end

[Share]
# any name you like
path = /home/share

# shared directory
writable = yes

# writable
guest ok = yes

# guest OK
guest only = yes
# guest only

create mode = 0777
# fully accessed

directory mode = 0777
# fully accessed
share modes = yes
启动samba
service smb start
service nmb start

开机启动samba
chkconfig smb on
chkconfig nmb on

3, install VMware

VM环境依赖包
yum install gcc gcc-c++ kernel-headers libXtst-devel libXrender-devel xinetd ncurses ncurses-devel bison libgcrypt perl -y
yum install kernel* -y
reboot

查看module路径
# locate libpk-gtk-module.so
/usr/lib64/gtk-2.0/modules/libpk-gtk-module.so
# locate libcanberra-gtk-module.so
/usr/lib64/gtk-2.0/modules/libcanberra-gtk-module.so

添加系统加载modules的路径。
vim /etc/ld.so.conf.d/gtk-2.0.conf
添加
/usr/lib64/gtk-2.0/modules

重新加载。
ldconfig

赋予VM安装包执行权限
chmod -R 777 VMware-Workstation-Full-9.0.4-1945795.x86_64.bundle

安装VM--然后一路Next就可以了。
./VMware-Workstation-Full-9.0.4-1945795.x86_64.bundle

查看已经安装的虚拟机
vmware-installer -l

卸载VM
vmware-installer -u vmware-player

远程可以直接打开图形
vmware-player

启动vmware-player
service vmware-player start

开机启动
chkconfig vmware-player on

4, XFS 安装配置

安装xfs
yum install xfsprogs xfsdump -y

创建新分区
fdisk /dev/sdb1
Command (m for help): n           创建新分区

Command action
   e   extended
   p   primary partition (1-4)
p                             创建主分区

Partition number (1-4): 1          新建的主分区序号
First cylinder (1-10402, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-10402, default 10402):     创建主分区大小

Command (m for help): w       保存创建的主分区

格式化分区
mkfs.xfs -f /dev/sdb1

创建挂载目录
mkdir -p /home/xfs

挂载硬盘到目录
mount /dev/sdb1 /home/xfs

查看硬盘号
blkid /dev/sdb1
/dev/sdb1: UUID="493b0f40-093c-47e0-8d48-3f169191ad9d" TYPE="xfs"

配置开机自动挂载
vi /etc/fstab
添加开机挂载目录
UUID=493b0f40-093c-47e0-8d48-3f169191ad9d /home/xfs xfs defaults 0 1

重启服务器
reboot

查看挂载目录
df -TH
