#make && make install

#cd apr-util-1.5.4

#./configure --prefix=/opt/app/apr-util --with-apr=/opt/app/apr

#make && make install 

#cd pcre-8.40

#./configure --prefix=opt/app/pcre

#make && make install

# tar zxf  httpd-2.4.25.tar.gz

# cd http-2.4.25

# ./configure --prefix=/opt/app/apache2.4.25 --with-apr=/opt/app/apr --with-apr-util=/opt/app/apr-util --with-pcre=/opt/app/pcre --with-mpm=worker --enable-rewrite --enable-so --enable-headers --enable-expires --enable-deflate
