Page number alignment

Question

This is my code:

\usepackage[french]{minitoc}
\fancyfoot{}
\fancyfoot[RO,LE]{ \textbf{ \small \textsf{\thepage}}}
\documentclass[12pt,a4paper]{book} 
\usepackage[T1]{fontenc}
\renewcommand{\baselinestretch}{1.5} 
\begin{document}
\include{Chapter1}
\include{Chapter2}
\end{document}

With this code, I have the number of pages: one on the left and one the right. I ask how can change it all on the middle? And the first page of each chapter (which contains the minitoc) is without number, I ask how can add a number of page in this page?

Answer 1

The first part of your question should be fixed with this...

\fancyfoot[C]{\textbf{\small\textsf{\thepage}}}

To change the plain fancy page style, which gets called at the start of the chapter

\fancypagestyle{plain}{
     \fancyfoot{}
     \fancyfoot[C]{\textbf{\small\textsf{\thepage‌​}}}
}

The above can also be used to create a new fancy page style by changing plain to xyz, for example, I have used this for various documents, it is a more comprehensive command than the above, since it resets everything first via the \fancyhf{} command.

%Header and Footer.
\usepackage{lastpage}
\fancypagestyle{detailed}{
    \fancyhf{} % clear all header and footers
    \fancyfoot[R]{\footnotesize{Page. \thepage~of~\pageref{LastPage}}}
    \renewcommand{\headrulewidth}{1pt}
    \renewcommand{\footrulewidth}{1pt}
 }

Then you can call

\thispagestyle{detailed}

for a single (local) instance, or,

\pagestyle{detailed}

to set the pagestyle from that point forward or until something else changes it.
