安装FusionInsight

1、在华为平台上下载整体客户端,不建议下载单个组件客户端,后期关联测试还是要装上的。
安装FusionInsight
 
2、下载后需要将服务器上的客户端拷贝到本地。打开xShell,新建会话,登陆本地虚拟机上的Linux系统(192.168.56.110),然后使用远程命令
ssh root@192.168.95.41       //41~46都是服务器地址
输入密码以后即可。
进去以后使用命令 ll  发现没有什么文件,
 cd tmp 报没有这个文件,cd /tmp后进入目录
ll后发现下载的文件FusionInsight_Client
3、远程拷贝:scp FusionInsight_cilent root@192.168.56.110:/root/software/
 4、exit 退出远程
 
 
 
linux scp远程拷贝文件及文件夹,需要的朋友可以参考下
 

1、拷贝本机/home/administrator/test整个目录至远程主机192.168.1.100的/root目录下

复制代码

代码如下:

scp -r /home/administrator/test/ root@192.168.1.100:/root/

2、拷贝单个文件至远程主机

复制代码

代码如下:

scp /home/administrator/Desktop/old/driver/test/test.txt root@192.168.1.100:/root/

其实上传文件和文件夹区别就在参数 -r, 跟cp, rm的参数使用差不多, 文加价多个 -r

3、远程文件/文件夹下载

举例,把192.168.62.10上面的/root/文件夹,下载到本地的/home/administrator/Desktop/new/下,使用远程端的root登陆

复制代码

代码如下:

scp -r root@192.168.62.10:/root/ /home/administrator/Desktop/new/
 
 
   ********************************
 
删除文件夹实例:
rm -rf /var/log/httpd/access
将会删除/var/log/httpd/access目录以及其下所有文件、文件夹
~~~~~~~~~~~~~~~~~~~~~
把当前目录的一个子目录里的文件移动到另一个子目录里 mv 文件名/* 另一个目录 ~~~~~~~~~~~~~~~~~

Linux时间同步NTP服务的安装与配置

[日期:2016-10-12] 来源:Linux社区  作者:dagege [字体:  ]
 

当我们需要管理多台Linux服务器的时间时,一台一台的修改未免太麻烦了,NTP服务就很好的为我们解决了这个问题!

1.首先安装NTP

[root@localhost /]# yum install ntp -y

2.修改NTP配置文件,添加NTP服务器的网络位置  vi   /etc/ntp.conf

# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5). driftfile /var/lib/ntp/drift # Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default nomodify notrap nopeer noquery # Permit all access over the loopback interface. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict ::1 # Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap # Use public servers from the pool.ntp.org project.Please consider joining the pool (http://www.pool.ntp.org/join.html).
server 192.168.1.1 iburst #目标服务器网络位置
#server 1.CentOS.pool.ntp.org iburst #一下三个是CentOS官方的NTP服务器,我们注释掉
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst #broadcast 192.168.1.255 autokey # broadcast server
#broadcastclient # broadcast client
#broadcast 224.0.1.1 autokey # multicast server
#multicastclient 224.0.1.1 # multicast client
#manycastserver 239.255.254.254 # manycast server
#manycastclient 239.255.254.254 autokey # manycast client # Enable public key cryptography.
#crypto includefile /etc/ntp/crypto/pw # Key file containing the keys and key identifiers used when operating
# with symmetric key cryptography.
keys /etc/ntp/keys # Specify the key identifiers which are trusted.
#trustedkey 4 8 42 # Specify the key identifier to use with the ntpdc utility.
#requestkey 8 # Specify the key identifier to use with the ntpq utility.
#controlkey 8 # Enable writing of statistics records.
#statistics clockstats cryptostats loopstats peerstats # Disable the monitoring facility to prevent amplification attacks using ntpdc
# monlist command when default restrict does not include the noquery flag. See
# CVE-2013-5211 for more details.
# Note: Monitoring will not be disabled with the limited restriction flag.
disable monitor

保存退出

3.启动服务并设置开启自启

[root@localhost /]# systemctl start ntpd.service  #启动服务
[root@localhost /]# systemctl enable ntpd.service  #设置为开机启动

4.查看运行状态

[root@localhost /]# systemctl status ntpd.service
● ntpd.service - Network Time Service
  Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
  Active: active (running) since 二 2016-10-11 13:34:11 CST; 8min ago
 Main PID: 6497 (ntpd)
  CGroup: /system.slice/ntpd.servicess
          └─6497 /usr/sbin/ntpd -u ntp:ntp -g

可以看到当前的状态为 running
