设置工作者 MPM 时出现问题

无法使 MPM Worker 工作..

我已经安装了该php-zts软件包，取消了注释#HTTPD=/usr/sbin/httpd.worker并/etc/sysconfig/httpd重新启动了 httpd 服务。

httpd 打印输出：

[root@web06 ~]# httpd -V

阿帕奇：

[root@web06 ~]# apachectl -v

Server built:   Sep  3 2009 17:41:45
[root@web06 ~]# apachectl -l
Compiled in modules:
  core.c
  worker.c
  http_core.c
  mod_so.c

服务器的详细信息：

Linux web 2.6.18-164.15.1.el5PAE #1 SMP Wed Mar 17 12:14:29 EDT 2010 i686 i686 i386 GNU/Linux

为什么 https 在 prefork 模式下仍然可以工作？

我感觉我错过了一些非常基本的东西......

谢谢！

输出sh -x /etc/init.d/httpd start > /tmp/apache.debug 2>&1

运行@quanta 的命令后：

[root@web06 ~]# ps -ef | grep httpd
root     16303     1  0 08:29 ?        00:00:00 /usr/sbin/httpd.worker

不知道为什么第一次检查ps -ef | grep httpd仍然显示/usr/sbin/httpd，但是因为我在调试中看到以下内容：

+ /bin/bash -c 'ulimit -S -c 0 >/dev/null 2>&1 ; /usr/sbin/httpd.worker'
...
+ success 'httpd.worker startup'

我很确定你的 Apache 正在工作模式下运行，第二次检查证明：

[root@web06 ~]# ps -ef | grep [h]ttpd
root     16303     1  0 08:29 ?        00:00:00 /usr/sbin/httpd.worker
apache   16305 16303  2 08:29 ?        00:00:37 /usr/sbin/httpd.worker
apache   16307 16303  2 08:29 ?        00:00:35 /usr/sbin/httpd.worker

不用来httpd -V检查 Apache 运行的模式，因为：

# which httpd
/usr/sbin/httpd

改用apachectl -V（大写）：

Server version: Apache/2.2.3

或者/server-info：

$ lynx -dump http://yourdomain.com/server-info | grep -i mpm
   MPM Name: Worker
   MPM Information: Max Daemons: 1 Threaded: yes Forked: yes
   Server Built With: -D APACHE_MPM_DIR="server/mpm/prefork" -D
          AcceptMutex - Valid accept mutexes for this platform and MPM
