Four, after the successful landing, will pop up 2 new windows, is a command line window, a sftp window. The command line window, is usually the most commonly used, installs the software, compiles the program and so on uses it. Another SFTP window that can be used to transfer files.

SFTP window I will not be introduced in detail, the peaceful use of the FTP software is the same, you can upload or download the file, this is very practical, attention, do not understand which file practical use, do not arbitrarily delete files, otherwise it may lead to a VPS error.

Next, I'll focus on a few of the most frequently used commands in SSH:

1. The top command can view the system status in real time:

The focus area is the first row of the load average is the system load, that is, the entire VPS resource occupancy, if the normal station, usually rarely more than 5 of the time, burst more than 20 will be sealed. The third row of the first, this is CPU consumption resources. And the back? %wa This is the hard drive state, the CPU is normally best not more than 30% of the occupied. WA index long-term more than 30%, basically hard drive is not to force state. The four rows are memory, how much, how much, how much.

Press CTRL + C to stop executing the current program and return to #.

2.wget command to download files, for example:

wget http://cachefly.cachefly.net/100mb.test

Download cachefly files, test your VPS bandwidth and network situation to power or not? Compare DS2 knife 1G, download speed 70m/s,vpsyou hundred trillion mouth, download speed 9.8m/s.

3.VI command This is an editor, similar to the Notepad Notepad under win:

Vi/etc/ssh/sshd_config

Simple to say the use of VI process, vi a file, and then press I, the lower left corner will show inserts, this time before you can modify this file. After modification, press ESC to insert and disappear in the lower left corner, and then enter: The bottom left corner appears:, then enter X, return, then save to exit.

Delete the # (note) before Port 22 and modify port 1688. Then, performing the service sshd restart will modify your default SSH port number of 1688 to enhance security performance.

4.chmod Command #后就是这个命令的说明

chmod +x/home/auto.sh # gives auto.sh executable permissions

Chmod-r 777/home/wwwroot # gives/home/wwwroot Write permission (required for partial web site program installation)
