graceful restart detection in prefork mode
Dear developers, My situation is following: In my Apache2 running in prefork mode I have following situation. Whole pages (except loging page) are run over https (port 443) and authentication is done over my own module. When the most users are looking on the pages (https) then I would like to reload configuration of my apache over command apache2ctl -k graceful I suggest that new users will see new configuration and old users will have their session till they will not logout. But unfortunatelly all sessions are closed and as new as old users have to login again for other work. Is there any solution for that like detection for gracefull restart? Do you now any idea how to do that? My apache2 which is delivered by SUSE is pretty old (I know). linux:~ # httpd2 -l Compiled in modules: core.c prefork.c http_core.c mod_so.c linux:~ # httpd2 -V Server version: Apache/2.2.3 Server built: Apr 14 2010 11:41:47 Server's Module Magic Number: 20051115:3 Server loaded: APR 1.2.2, APR-Util 1.2.2 Compiled using: APR 1.2.2, APR-Util 1.2.2 Architecture: 32-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with -D APACHE_MPM_DIR=server/mpm/prefork -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT=/srv/www -D SUEXEC_BIN=/usr/sbin/suexec2 -D DEFAULT_PIDLOG=/var/run/httpd2.pid -D DEFAULT_SCOREBOARD=logs/apache_runtime_status -D DEFAULT_LOCKFILE=/var/run/accept.lock -D DEFAULT_ERRORLOG=/var/log/apache2/error_log -D AP_TYPES_CONFIG_FILE=/etc/apache2/mime.types -D SERVER_CONFIG_FILE=/etc/apache2/httpd.conf linux:~ # Thank you in advance. -- Best Regards / S pozdravem Petr Hracek
