Hi All: Thank you all for taking time to read this message. I got two things that i really don't understand. 1. I got RedHat6.2. I tried to install modperl. Apache1.3.12 and modperl 1.24. I installed every prerequired package. Configuration is fine and compiling is fine without any errors. But i never got test passed. The error messages: httpd listening on port 8529 will write error_log to: t/logs/error_log letting apache warm up...\c done /usr/bin/perl t/TEST 0 still waiting for server to warm up...............not ok server failed to start! (please examine t/logs/error_log) at t/TEST line 95. make: *** [run_tests] Error 9 I check error.log file: [notice] Destruction->DESTROY called for $global_object [Tue Jun 13 18:42:39 2000] [warn] [notice] child_init for process 20497, report any problems to [no address given] There is nothing i can do. I am so frustrated because we has another machine upgrated from redhat5.2 to 6.1. We installed modperl without any problem. We tested everything ok. Please point out. Greate Thanks. 2. Since i can't get my new modperl running. I just use modperl coming with redhat6.2. The weired thing is that if i put PerlModule Apache::DBI in httpd.conf, the web server can not startup. If i take that out, the server can connect with database ( because i put use DBI; in perl script file?). But i can't get persistent connections, sometimes it can connect with database (mysql), sometimes it can't connect database with the following errors DBD::mysql::st execute failed: MySQL server has gone away at cnznetmod.pm line 1 59. DBD::mysql::st fetchrow failed: fetch() without execute() at cnznetmod.pm line 1 60. DBD::mysql::db do failed: MySQL server has gone away at cnznetmod.pm line 151. DBD::mysql::st execute failed: MySQL server has gone away at cnznetmod.pm line 1 59. DBD::mysql::st fetchrow failed: fetch() without execute() at cnznetmod.pm line 1 60. DBD::mysql::st execute failed: MySQL server has gone away at cnznetmod.pm line 1 30. DBD::mysql::st fetchrow failed: fetch() without execute() at cnznetmod.pm line 1 31. But it works in most time. I can't turn on debug because i can't put PerlModule Apache::DBI in httpd.conf. Thank you very much... Steven.
