httpd tomcat mod_jk.so整合

[linjky]

系统：centos7 mini
httpd2.4.6和tomcat7.0.69都是用yum安装。两个服务都可以正常使用。但配置了mod_jk后httpd就无法启动了。
mod_jk.so是用源码编译的，版本1.2.42，此文件命名为mod_jk-1242.so放在"/etc/httpd/modules"目录下。
然后在"/etc/httpd/conf"目录下生成mod_jk-1242.conf和workers.properties两个文件。
mod_jk-1242.conf内容：(此文件已在httpd.conf中导入)
LoadModule jk_module modules/mod_jk-1242.so
JkWorkersFile conf/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkshmFile /var/log/httpd/mod_jk.shm
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /servlet/* worker1
JkMount /*.jsp worker1
JkMount /*.do worker1
JkMount /*.action worker1

workers.properties内容：
worker.list=worker1
worker.worker1.port=8009
worker.worker1.host=127.0.0.1
worker.worker1.type=ajp13
worker.worker1.lbfactor=1
配置完后启动httpd出错，提示我用systemctl status httpd 和 journalctl -xe 查看信息

systemctl status httpd信息：

找了好多天了，一直找不到错在哪，只要把mod_jk配置文件注释掉就httpd可以正常启动，请高人给找找问题出在哪？？？

今天查了下httpd的error_log里面有写： Initializing shm:/var/log/httpd/mod_jk.shm.2247 errno=13. Unable to start due to shared memory failure.

用debug记录了下mod_jk.log,内容如下： [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] jk_set_time_fmt::jk_util.c (486): Pre-processed log time stamp format is '[%a %b %d %H:%M:%S %Y]' [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] dump_options::mod_jk.c (674): JkOption 'ForwardURICompat' set in server 'localhost.localdomain' [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] dump_options::mod_jk.c (682): JkOption 'ForwardURIEscaped' set in server 'localhost.localdomain' [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] dump_options::mod_jk.c (706): JkOption 'ForwardKeySize' set in server 'localhost.localdomain' (default) [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] dump_options::mod_jk.c (734): JkOption 'CollapseSlashesUnmount' set in server 'localhost.localdomain' (default) [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_open::jk_uri_worker_map.c (900): rule map size is 2 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_add::jk_uri_worker_map.c (850): wildchar rule '/servlet/*=worker1' source 'JkMount' was added [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_add::jk_uri_worker_map.c (850): wildchar rule '/*.jsp=worker1' source 'JkMount' was added [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_dump::jk_uri_worker_map.c (178): uri map dump after map open: id=0, index=0 file='(null)' reject_unsafe=0 collapse_slashes=3 reload=60 modified=0 checked=0 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_dump::jk_uri_worker_map.c (185): generation 0: size=0 nosize=0 capacity=0 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_dump::jk_uri_worker_map.c (185): generation 1: size=2 nosize=0 capacity=4 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_dump::jk_uri_worker_map.c (198): NEXT (1) map #0: uri=/servlet/* worker=worker1 context=/servlet/* source=JkMount type=Wildchar len=10 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] uri_worker_map_dump::jk_uri_worker_map.c (198): NEXT (1) map #1: uri=/*.jsp worker=worker1 context=/*.jsp source=JkMount type=Wildchar len=6 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] init_jk::mod_jk.c (3533): Setting default connection pool max size to 1 [Mon Aug 07 14:15:33 2017][2425:140429726779520] [debug] jk_map_read_property::jk_map.c (501): Adding property 'worker.list' with value 'worker1' to map.

今天找到了JkshmFile /var/log/httpd/mod_jk.shm这里的一个错误，给改成JkShmFile /var/log/httpd/mod_jk.shm后还是报一样的错误。郁闷了！！！ 今天直接新装了一个centos7用源码安装了httpd-2.4.27、tomcat-8.5.16、mod_jk-1.2.42后竟然配置成了！！！ 上的面的贴子中的错误还是解决不了。版本兼容的问题？我看又不像呀。 配置成功后我试了试，写下我的感觉，如果不对，希望以后的各位多加指正： 只能apache调用tomcat解读jsp，不能tomcat调用apache解读html； jsp文件要在tomcat的web目录里，而apache的web目录里可以没有这个jsp文件,而html文件相反。 难道以后要在两个web目录里都部署上网站？或两个web目录指定同一个web目录？ 以后这个网站有个登录、session或其它什么的能正常工作？ 先到这，以后有什么不懂的再来补充。如果有哪位高人看到这个贴子的话帮忙回答一下，如果不时间不方便，也请说个方向，我可以自己去查。

试试是不是SELinux的影响。 “setenforce 0”临时关闭SELinux后启动httpd试试。

[linjky]

那个虚拟机我给删了，看不了了，不过我感觉应该不是SELinux的问题。我上面不是有一个用源码安装成功的列子吗？那个例子就没有就没有关闭SELinux。 不过还是感觉你回答我的问题，非常感谢。

[linjky]

再回复下，也没是SELinux的问题，我装的虚拟机有点多，有点忘了到底关没关闭它了

[linjky]

我试过了，跟SELinux没有关系。

今天查了下httpd的error_log里面有写： Initializing shm:/var/log/httpd/mod_jk.shm.2247 errno=13. Unable to start due to shared memory failure.

看看有没有这个文件 /var/log/httpd/mod_jk.shm
