Fix Permission problems on servers<\/h1>\n

Notice: If you are not familiar with linux and unsure how to
\ncorrectly execute commands, we advise that you
\nbackup current server, before making the below changes. <\/em><\/sup><\/span><\/p>\n

Many times, on VPS servers (ubuntu, linux, debian, etc…) you might face an issue, like in PHP, showing an error message like:<\/p>\n

Warning: rename\/move\/write\/access\/create …..<\/span><\/strong>\u00a0Permission denied in\u00a0<\/strong> \/path\/your_file.php<\/p>\n

Most times, the reason could be that one user (like root<\/strong>) owns the directory, and another user (i.e. www-data<\/strong>, which is apache instance user) tries to modify the file. For me, the best solution to such problems was to create a Group<\/strong> of users (let’s name it myusers<\/strong>), consisting of both root<\/strong> and www-data<\/strong>:<\/p>\n

groupadd myusers<\/strong>\ngpasswd -a www-data   myusers \n<\/strong>gpasswd -a root       myusers\n<\/strong>gpasswd -a other_user myusers<\/strong><\/pre>\n
and then give that group the needed privileges (change your desired path):<\/p>\n
sudo chown<\/a> -R :myusers \/var\/www\/<\/span><\/strong><\/pre>\n
So, you can modify the file\/folder from i.e. FTP or terminal, and also from Web-interface (which is Apache).\u00a0 And finally, assign correct chmod<\/code> permissions to\u00a0d<\/code>irectories and f<\/code>iles :<\/p>\n
find \/var\/www\/<\/span> -type d -exec chmod u+rwx,g+rwx,o+rx {} \\;\nfind \/var\/www\/<\/span> -type f -exec chmod u+rw,g+rw,o+r {} \\;\n<\/strong><\/pre>\n
That’s all .\u00a0<\/strong>(btw, sometimes, instead of rwx<\/code>\u00a0you might need\u00a0rwxs<\/strong><\/code>)<\/sup><\/p>\n
Definitions<\/em>:
\n<\/sub>*u<\/code> = <\/span>user<\/code>, <\/span>g<\/code> = <\/span>group<\/code>, <\/span>o<\/code> = <\/span>others<\/code>
\n* r<\/code> = <\/span>read<\/code> (same as <\/span>4<\/code>), <\/span>w<\/code> = <\/span>write<\/code>(same as <\/span>2<\/code>), <\/span>x<\/code> = <\/span>execute<\/code>(same as <\/span>1<\/code>)
\n<\/span>i.e. rwx<\/code> is 4+2+1 = 7<\/code>; So,\u00a0<\/sub> u+rwx,g+rwx,o+rx<\/code>\u00a0<\/strong>is same as\u00a0775<\/code><\/strong>
