Solucion:

El problema está en que no se encuentra la librería libcrypto.a

La solucion es instalar openssl, siguiendo estos pasos:

cd /home/install/servicios/apachessl/
# Origen: http://www.openssl.org/source/openssl-0.9.6b.tar.gz∞


wget ftp://ftp.uniovi.es/pub6/www/security/ssl/OpenSSL/openssl-0.9.6b.tar.gz∞

cd /usr/src/
tar -zxvf /home/install/servicios/apachessl/httpd-2.0.35.tar.gz
tar -zxvf /home/install/servicios/apachessl/openssl-0.9.6b.tar.gz
ln -s /usr/src/openssl-0.9.6b /usr/src/ssl

# Se compila SSL

SSL_BASE=/usr/src/ssl
cd /usr/src/ssl/
ln -s /usr/bin/perl /usr/local/bin/perl
./config
make
make test
make install

ln -s /usr/local/ssl/lib/libcrypto.a /usr/lib/libcrypto.a
ln -s /usr/local/ssl/lib/libssl.a /usr/lib/libssl.a


ERROR al arrancar Apache:

$ /etc/rc.d/init.d/httpd start
/etc/rc.d/init.d/httpd start: httpd could not be started

SOLUCION:

Ver detenidamente el contenido del log de error:

$ tail /var/log/httpd/www.midominio.com/error.log
[Sun Jul  7 11:22:00 2002] [error] (2)No such file or directory:
could not open transfer log file /usr/local/apache/logs/www.midominio.com/access.log.

Vemos que el directorio /usr/local/apache/logs/www.midominio.com/
no existe. Lo tenemos que generar, en este caso:

mkdir /usr/local/apache/logs/www.midominio.com/
