![]() I recommend this guide for understanding the ownership/permissions system in Ubuntu (which also applies to most other Unix-like OSes). The following command grants the user full access to the specified database, but the user cannot grant or take privileges from other users.make sure not to do so for more files than necessary-for example, some people accidentally change ownership or permissions for large parts of the system and then have to reinstall, and.If you need to change ownership and permissions for files, then: You can do that as root from the Terminal with cp, chmod and chown (run as root with sudo), or with a root-owned Nautilus window as described above. If there are files there that you want, then you can copy them out (and if their ownership and permissions don't give you the necessary access, change them). If you think there may be files there that you wish to reclaim, you can check by running sudo ls /lost+found Since such files could be from anywhere in the filesystem, it's necessary to require root permissions to access them (or any information on the system could potentially be accessed by someone who is not an administrator). From the manual: -i, -login Run the shell specified by the target users password database entry as a login shell. This stores files recovered in filesystem repair operations. If you want to execute a series of commands as the root user without having to prefix every command with sudo every time, I recommend using sudo -i to grab a login shell as the root user. The particular task you need to do will determine how you should proceed.įinally, a note on lost+found. Scripts writable by Unix users other than the Unix user that are executed (cron or directly) by the unix user. Extensive sudo access grants that provide users with access to execute commands of a different Unix user. I logged in through sudo mysql and checked the user table, ie. ![]() I recommend providng more information-or asking a new question-to explain exactly what you're trying to accomplish. Common access areas without screen locks, where an unauthorized user accesses the logged in Unix user of an authorized user. After I installed it and started the process (sudo service mysql start), I cannot login as root even though I originally set the password to blank. You rarely have to manually edit the top-level contents of / or the contents of /root. However, usually you don't need to do that either. (In contrast, if you were to use plain sudo nautilus, you might have to fix some things in your home directory to get Nautilus to work properly again when you're not running it as root.) If you don't have gksu installed and don't want to install it, sudo -i nautilus or sudo -H nautilus are reasonably safe. If you do this, please be extra careful to only use it for tasks where you must be root, and to close it when you're done (so you don't later confuse it with an ordinary Nautilus window). If you have the gksu package installed, you can run gksudo nautilus to open a root-owned file browser window. You should not change the ownership or permissions of either directory (changing them for / in particular could break things very badly, perhaps even beyond creating security problems depending on what assumptions your applications and services make about the ownership and permissions of /). During the normal course of operation (i.e., except while performing administrative tasks), users cannot create new files in / or /root. On Ubuntu, these need to be same….because you only get one chance to pass through a name and password when logging into a server from HeidiSQL.There are two different folders called the "root" folder: / (the root of the filesystem, which is really the only folder that should ever be called the "root folder"), and /root (the root user's home directory). ![]() To connect to mySQL, you need to have two valid accounts: a.) a valid Linux user account, and b.) a valid mySQL user account. Create a mySQL user with an identical name and password as the Ubuntu user account. So, more or less in order, I did the following:ġ. The symptoms of the problem showed up in an error message, generated by HeidiSQL:Ĭonnect Error ( 2003 ) Can ‘t connect to MySQL server on ‘192.168.219.107 ‘ (10061) I expect that I would have the same problems attempting to connect with similar client software, such as mySQL Workbench or PHPmyAdmin. ![]() After creating a new mySQL server within an Ubuntu guest OS running on VirtualBox, (how is that for a mouthful?) I wanted to connect to the server with HeidiSQL, my toolbox of choice when dealing with basic SQL operations.
