chmod 755

What chmod 755 means

755 (rwxr-xr-x) is the standard permission for directories and executable files. On a directory it lets everyone list and enter it while only the owner can add or remove files. On a file it makes a script or program runnable by everyone but editable only by you.

Typical uses: web root and its sub-directories, ~/bin scripts, and anything in /usr/local/bin. Combined with 644 for files it's the classic safe setup for websites.
