Article Title: server hardware check and file transfer in Linux. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, need to check servers recently. I hope to check the information, then, all the files are packaged and sent to a master server for batch processing.
Let's take a look at how to handle the relevant content:
Command for viewing hardware information: linux:
Memory: cat/proc/meminfo
Cpu: cat/proc/cpuinfo
Hard Disk: df-h-T (no device is visible)
Fdisk-l can be viewed in redhat9.0; redhat Enterprise Edition does not work.
Solaris:
Nic speed: dmesg | grep link
CPU frequency: psrinfo-v or mpstat
Cpu/memory, etc.: prtdiag-v (most of the information is listed) needs to first enter/usr/platform/sun4u/sbin
Hard Disk: iostat-E
There are several commands in linux to view the information of many hardware devices.
Lspci-v
Dmidecode
Dmesg
For more information about file transfer methods, see:
There are three common methods to copy files between different Linux systems. The first method is ftp, that is, installing the ftp Server on one of the Linux systems, in this way, another ftp client program can be used to copy files. the second method is to use the samba service, similar to the Windows file copy method, which is simple and convenient. The third method is to use the scp command to copy files.
Scp is a file copy with Security and is used for ssh logon. For example, to copy the current file to another remote host, you can run the following command.
Scp/home/daisy/full.tar.gz root@172.19.2.75:/home/root
Then, you will be prompted to enter the logon password of the root user of the other 172.19.2.75 host, and copy the password.
If you want to copy files from the remote host to the current system, it is also very easy.
Root@172.19.2.75 scp:/home/root/home/daisy/full.tar.gz
The hard disk information can be as follows:
Df-h-T>/root/info/hd.txt
The memory can be as follows:
Cat/proc/meminfo>/root/info/mem.txt
Then copy the startup script to perform the check:
Cp/etc/rc. local/root/info/mem.txt
Copy the scheduled task script to perform the check:
Cp/etc/crontab/root/info/crontab.txt
Check the current program list:
Top-n1>/root/info/top.txt
You can also put it in a folder for checking.
Then package:
Tar cvfz info.tar.gz./info
Transfer to the server:
Scp/root/info.tar.gz root @ target_server:/home/root
Finally, there are several statements:
SERVER_IP=127.0.0.1cd /rootrm -R -f info_$SERVER_IPmkdir info_$SERVER_IPdf -h -T >/root/info_$SERVER_IP/hd.txtcat /proc/meminfo_$SERVER_IP >/root/info_$SERVER_IP/mem.txtcp /etc/rc.local /root/info_$SERVER_IP/rc.local.txttop -n1>/root/info_$SERVER_IP/top.txttar cvfz info_$SERVER_IP.tar.gz ./info_$SERVER_IPrm -R -f info_$SERVER_IPscp info_$SERVER_IP.tar.gz root@target_server:/home/rootrm -f info_$SERVER_IP.tar.gz
