wordpress on localhost lamp doesn’t let me install plugins

i’ve installed a LAMP server on my ubunutu 11.04.
i’ve installed wordpress and hooked it right with the MySQL db.
i’ve changed the permissions of the www-data group to read and write files.

every thing is seems to work and i can manage the site through the admin panel, but i can’t install plugins cause the system is asking me the FTP details, and i can’t seem to go through it.

  1. The solution I found that worked on my Mac running the built-in Apache2 was to add this to ‘wp-config.php’

    define('FS_METHOD','direct');

    Keep this to a localhost or dev setup and don’t use it for production.

  2. After installing WordPress 5 on Debian 9 Stretch I updated (remotely on localhost) and was prompted for FTP details.

    Running these commands in terminal fixed the problem:

    chown -R www-data:www-data /var/www/html
    chmod -R g+rwX /var/www/html
    

    It’s a file-ownership issue.

    Code and caveat from
    turnkeyLinux.com:

    Changing file permissions is a trade off
    (often increasing security reduces user-friendliness and/or
    usability). For security ‘best practice’ only the folders that require
    write access by the webserver should be owned by the webserver.
    If your webserver has write access everywhere and your server
    is compromised it makes it easier to hack your WordPress install) but
    for ease of use giving the webserver ownership should resolve all your
    issues…

  3. This is a permissions issue. Here are some steps to fix ownership and r/w permissions in a more secure way:

    // check what groups your username belongs to

    $ groups

    // if your username doesn’t belong to www-data then add username to group

    $ sudo usermod -a -G www-data username

    // exit ssh session (or close terminal window if local) to make group change stick

    $ exit

    // now give www-data group ownership of /var/www/html (you’re not modifying the owner, just changing group ownership here)

    $ sudo chgrp -R www-data /var/www/html

    // give necessary r/w permissions directories and files to users who are members of www-data

    $ sudo find /var/www/html -type d -exec chmod g=rwxs "{}" ;

    $ sudo find /var/www/html -type f -exec chmod g=rw "{}" ;

    // I like to check things before moving on

    $ ls -l /var/www/html/

    // you likely don’t need to restart apache, but if you want to

    $ sudo service apache2 restart

    Apache should now have r/w access to /var/www/html as well as any user that you shh/ftp in with that also belongs to www-data

  4. This isn’t a WordPress problem. You need to refer to the documentation for the LAMP server to check the setup options.

    For localhost, you can bypass plugin installation from WordPress and simply copy your plugins into /wp-content/plugins. After you copy them in, go to your WordPress administration and they will show up in your plugins ready to be activated.

    Make sure you unzip the plugins and keep them in their folders.

  5. You need two things to do

    1. Add WolfieZero has said

      define(‘FS_METHOD’,’direct’);
      in wp-config.php file

    At this point you will have following, which one step forward

    Unpacking the package…Could not create directory.

    2 Then set permission to 777 to wp-content/plugins

    After this it will show message like following

    Downloading install package from https://downloads.wordpress.org/theme/exclusive.1.0.32.zip…
    
     Unpacking the package…
     Installing the theme…
     Successfully installed the theme Exclusive 1.0.32.
    

    CHOWN should also work and it is better way of doing it that Server is in owner group.

  6. If you’re using mod_php, switch to mod_suphp instead. This has worked for me in the past.

    I don’t know what package it will be listed as in Ubuntu, but generally it’s there somewhere. Works in Fedora.

  7. I don’t know if you are answered…but what i have encountered especially when i was working on linux and i just thought maybe other users, especially who are working on linux might find this useful. I was facing the same problem…but i had to use the SSH2 option.

    How to install SSH2

    apt-get install openssh-server libssh2-php
    

    After that, i had to restart my apache2 server.

    Then when i tried to upload my theme i had to use SSH not FTP when asked for credentials.

    E.g

     Hostname: localhost
    
     FTP/SSH Username: admin
    
     FTP/SSH Password: password
    

    And it worked.

    Thanks.
