\newdimen\SmallR % node radius
\SmallR=0.5cm
\newcommand{\A}{360/7}
\begin{tikzpicture}
\node[circle,minimum size=2*\SmallR,draw,thick] (1) at (0,0) {1};
\foreach \X in {2,...,8}
{\node[circle,minimum size=2*\SmallR,draw,thick] (\X) at ({-\X*\A+180}:\R) {\X};}
\foreach \X in {2,...,8}
{\pgfmathtruncatemacro{\Y}{mod(\X-1,7)+2}
\draw[-latex] (\X)--({\Y});
\draw[-latex] (1)--({\Y});}
\end{tikzpicture}
\end{document}

When compiled with pdflatex, it produces
