hi,sir; i am installing php4.0.2+oracle8.1.16+apache1.3.14 in redhat7.0 ,first i installed apache at /opt/apache ,it run well. then i installed oracle at /opt/oracle and /opt/oraclient,as you see,i installed oci at /opt/oraclient.now oracle works well,too. at last,i try to install php as a dso in apache like this : shell> ./configure --with-apxs=/opt/apache/bin/apxs --with-oracle=/opt/oracle --with-oci8=/opt/oraclient --enable-track-vars ;make;make install shell> cp php.ini-dist /usr/local/lib it didn't show any error messages.then i start apache : [root@linux bin]# ./apachectl restart ./apachectl restart: httpd not running, trying to start ./apachectl restart: httpd started it looks like that apache is running.but ......i can't see 'httpd' when running 'ps -e' in console,and when i visit in ie5 ,i found apache didn't work.i changed httpd.conf ,change the line 'LoadModule php4_module libexec/libphp4.so' to '#LoadModule php4_module libexec/libphp4.so' and start apache again,this time it works well.i feel so stange,why? i installed apache like this shell>./configure --with-prefix=/opt/apache --enable-module=most --enable-shared=max so apache should support dso.in fact,i had installed php with mysql as dso,it works well.i think i made some mistake when configure php with oracle and oci8,who can give me some help?
