Written in front:
I have seen many netizens' questions about the server configuration, build a reliable and secure application development server is the basis of web programming, especially for friends who have developed JSP on Linux.
This document is the crystallization of my multi-year server configuration. I haven't been modified by my N before publishing (the last big revision is just released in RH7.2, and then because I have not found a mistake because I didn't find any mistakes, I didn't have it. Upgrade), documentation
Reprinted by Tianji Network at the end of 2001 (
Http://www.yesky.com/200206/217592.shtml), after linuxbye.net, CNJsp.COM is reproduced, after the time test, it has not been discovered, and you have not found it.

The document is longer, divided into more articles, this is the eighth article, the following is the text:

Example 4: Test PHP
1 Create a source file
Touch /Home/www/test.php
CHMOD 701 /HOME/www/test.php
2 Edit the source file
Vi Test.php
## The source code is as follows:
PHPINFO ();
?>
3 Test the program
Lynx http://www.yesgo.loc/test.php
/ / The result is a list of known server-side variables.
-------------------------------------------------- ------------------------------------------
Step 17 Configuration Debug
## The possible mistakes of the debugging process are as follows:
Frequently wrong one: you don't have permission
Forbidden
You don't have permission to access / on this server.
Apache / 1.3.22 Server AT
Www.yesgo.loc
Port
80
reasons may be:
1, you didn't set the guest group permissions for this directory or the file;
2, you didn't set this file name as the default page, especially in the case of only domain name access.
Solution:
CHMOD 701 / HOME / WWW
CHMOD 701 / HOME / WWW / *
vi /usr/local/apache/conf/httpd.conf
DirectoryIndex index.html index.jsp index.xtp index.php index.php3
Common Error 2: 404 Not Found
404 NOT Found / INDEX.JSP WAS NOT Found On this Server.
RESIN 2.0.5 (Built THU NOV 15

reasons may be:
1. You request the file name to enter an error;
2, you didn't build the corresponding host in resin.conf and httpd.conf.
Solution:
1. Check the file name, especially pay attention to the case;
2. Refer to the configuration supporting the JSP virtual host section in the RESIN Install step. Common error three: java.lang.classNotFoundException
500 Servlet Exception

reasons may be:
1. The host name, database name, account or password in the source code is incorrect;
2. If the database name, account number, password is correct, that is the description is that the host name does not match;
3. If you use a data source library, check if the data source settings and the name of the source code are entered correct.
Solution:
1. See RESIN INSTALL and Server Test;
Note: The database connection is not just the account and password, but is determined by the host name, database name, username, and password.
