PhpMyAdmin cannot start session without errors and the reasons why many open-source programs cannot go in the background

1. In fact, modifying the session. save_xxxx of PHP. ini based on what we have mentioned on the Internet does not have much effect. This error will be reported when the cookie is accidentally lost.

2. several open-source programs have been modified over the past few days. after logging in to several of them, the database can also be registered, and the background page can be opened. However, the database cannot be accessed. it is as if the background login is a static page.

After one night, I found that the new desktop was running well. So I started to look for the notebook configuration. Because I died once in the middle of the day, I couldn't find the reason.

Later, I suddenly remembered that the session used in the background was not a problem with the session parameters in my PHP. ini... so I found the original PHP. ini-Development and compared it.

I changed several session parameters a few days ago, so I changed them back and restarted Apache to solve the problem...

After taking the time to enable and disable the session parameters, write down the effect.

If you have this problem, you can refer.

3. If you cannot log on to. phpMyAdmin and other open-source programs under Linux, check the folder and file permissions and group permissions.

4: If sudo apt-Get is used for downloading, it is a local hard link. the permission of the hard link is worth considering. You can copy the original phpMyAdmin file to www.
