This article is not a dry product. Maybe we don't use many children's shoes! After all, this matter really wasted half a day of my research. I will share it with you here!
At present, the software platforms made in the company are sold to Party A, and many of them require localization deployment! Why is it called localization deployment?
At present, Party A is either a ZF or a state-owned enterprise, and some business platforms require intranet access.
The servers in the intranet are not connected to the public network (Internet). We usually configure a springboard machine to access the server.
The springboard machine can access both the public network and the servers in the LAN.
As shown in the figure:
Here comes the question: What should I do if I need to install some software on the server now?
Currently, they are generally compiled and installed! First download the software on the springboard machine, then copy it to the server, compile and install it!
The disadvantage of this method is that it is troublesome. There may be fewer packages in the compilation process!
At this time, I suddenly found that it was cool to install with the yum button. What should I do? Intranet server networking requires various approvals (within the system, you know)~
Can the server use a springboard machine to connect to the Internet to install these software?
As shown in the figure:
Platform system
The system demonstrated by the blogger is as follows
Server: CentOS 7
Jumpboard machine: Windows 10
Intranet: network cable
External network: wireless network card
Software: CCProxy
Basic steps
Start Agent
1) Download on official website CCProxy Software installation
2) This is divided into free version and paid version. It is recommended for everyone to use CCProxy registration code Activate it, otherwise limit the number of connections and the network speed is not ideal!
3) After installing the software, the settings can see some configurations
4) Support multiple protocols, such as HTTP and Socks
Which network card does the following 0.0.0.0 monitor? Huh? What? Don't know which to choose? Choose 0.0.0.0.
Intranet IP address
Query the intranet IP address of the springboard machine. This is simple!
1) Win+R input cmd, console input ipconfig
2) You can see all the network cards and the assigned IP addresses
3) Find the IP address assigned to the intranet of the springboard machine and server
For example, the IP address is 192.168.8.119
Server networking
Execute the following command on the server, and the server can go to the springboard machine agent!
export http_proxy= http://192.168.8.119:808 export FTP_PROXY= http://192.168.8.119:808 export ftp_proxy= http://192.168.8.119:808 export all_proxy= socks://192.168.8.119:808 export ALL_PROXY= socks://192.168.8.119:808 export HTTPS_PROXY= http://192.168.8.119:808 export https_proxy= http://192.168.8.119:808 export HTTP_PROXY= http://192.168.8.119:808 export no_proxy=localhost,127.0.0.1
Reminder: The above command is only for the current shell window. After the form is closed, the proxy will become invalid!
If you want to "permanently" take the proxy, you can add the above content to ~/.bash_profile
Execution: source ~/.bash_profile It will take effect!
Before using the proxy:
After using the agent:
Final summary
This method is really convenient! There are many similar software, such as HAproxy, Proximier, wait
