Recent problems and problems

1. two days ago, in order to build an OpenStack, errors always occur during installation. I thought that each installation package can be downloaded at the beginning, but errors may occur when it is downloaded, in addition, the download speed is extremely slow, so I guess it may be because the speed of foreign servers in China is too slow.

2. But it's too slow to go abroad. How can this problem be solved? At the beginning, I thought of finding an OpenStack source in China, so that I don't have to worry about it. I can use it directly, but it was unexpected, no yum source of OpenStack can be found. There are many common yum sources. What should we do?

3. I spent 18 RMB on the Internet to buy a vps and planned to build my own vpn Server. However, if I set up a vpn Server step by step, it would be too slow and I don't want to worry too much, you just want to use it recently.

4. Baidu went to a fast server building method and started to build the server. The speed was indeed very fast and it took several minutes to complete.

5. I tested the connection with my pc host and can connect to it. It seems that the speed is okay and access to Facebook is not very slow.

6. I applied it to the server, but it happened. It was clearly available on the PC, but once I visited the server, the website could not be opened. I guess it may not be done.

7. Open cmd, enter tracert to check the route, and check whether the path and dns resolution are correct. The result shows that the paths are completely correct, but the web page cannot be opened.

8. no way. I guess it may be caused by connection to multiple VPNs (because of the school's network settings, I connected two VPNs to bypass the school's billing system), leading to network speed, data packet sending, and other problems.

9. If you want to create a yum source

10. However, when yum is set up, it is found that the source on the official website is https protocol and cannot be connected using ftp. If you want to download the files one by one, you will not be exhausted.

11. So I went online to find a tool for downloading data from all URLs on a page.

12. Baidu once found that all of thunder could be used. After the experiment, he found that only a combination of letters is supported, and other full-site data packets do not seem to work.

13. After Thinking About Baidu, it is better to write a python script by yourself, so you don't have to manually grasp it. It is easier to run the script there.

14. Write a script and run it to capture data. Started to test locally, there is always a write

import urllib      con=urllib.urlopen('https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/epel-6/').read()  tail=con.find(r'repodata/</a>',0)      while con.find(r'<a href=',tail)>0:      title=con.find(r'<a href=',tail)      start=con.find(r'="',title)      tail=con.find(r'">',start)      filename=con[start+2:tail]    url="https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/epel-6/"+filename    print url    content=urllib.urlopen(url).read()    openfile=open(filename,"wb")      openfile.write(content)      openfile.close()else:      print "it is end!"  

I thought there was a problem with the program writing. I checked the error and found that I/O permissions were insufficient. So I migrated the Directory and the test was successful. Start to download data. You only need to wait until the download is complete and then create a yum source.

For a recent IE Problem

125.64.34. *: The 80 section is a server of Chengdu Telecom, which is invincible and slow. It directly breaks down the entire page. this is a rogue of Chengdu Telecom. It is random and inserted directly into the HTTP header, rather than DNS spoofing. therefore, it can only be blocked by access control tools (such as Privoxy or Firefox + INS. or you do not need to use China Telecom.
His principle is that ADSL must access the Internet through the underlying port of the Telecom, so he forced the advertisement to be inserted by PAGE redirection. The Code is as follows:
Call 10000 and ask them to cancel the call. The phone number is free of charge! Keep calling and check out
How hooligans are there in China Telecom!

Recently, I encountered some work problems, such as: how to keep meeting records?

Dizzy, what do you call meeting records like that ??? According to my opinion, the meeting summary is similar.
In fact, you just need to sum up what each person says into one or two words.
For example:
Meeting Time: PM
Meeting topic: questions about work
Participants: A, B, and C
HOST: D
Meeting content:
A: How can I get started at work?
B: Actually how?
C: What do I think?
Meeting conclusion: employees do not trust each other. They are not active when they do their jobs. They need to communicate with each other. If they encounter problems and cannot solve them, they should discuss each other and discuss the results, you need to complete the work in time ........
This is not the case. If you don't give me a score, I really want to say to you, "Never say that you have been in college .... Even the meeting format is unknown !!!!" ""
I will also tell you that the meeting concluded that you have written the same text as the saliva article, so you can use more textual content...
