Programming Technology-compile cgi in a self-made C language to implement the search function-general Linux technology-Linux programming and kernel information. The following is a detailed description. 1. Environment
/Usr/local/apache/htdocs/(the file to be retrieved is in this directory)
/Usr/local/apache/temp/(as a transit folder)
/Usr/local/apache/cgi-bin/
2. Place a. out generated by gcc search. c in/usr/local/apache/cgi-bin/, and set the permission to nobody.
.
3. chown-R nobody. nobody/usr/local/apache/temp
4. Add the deletetemp permission to/etc/cron. daily to 555.
Rm-f/usr/local/apache/temp /*
5. Add a file myupdate permission to/etc/cron. hourly to 555.
Updatedb-U/usr/local/apache/htdocs
6. delete a file slocate. cron in/etc/cron. daily.
