VM 上的Apache 2有时没有找到mods

2018-06-22 21:20:38

我在Ubuntu 10.04服务器虚拟机（ESXi 4.1）上运行Apache 2，并得到一些非常奇怪的东西：

有时会找到启用mods的目录。
有时候不是。似乎没有找到约75％。
两者之间没有任何变化。

下面是error.log中的一些摘录，结合命令行来演示发生了什么：

所以我开始停止Apache，以便更轻松地在日志中找到东西：

CMDLN: root@bunny:/etc/apache2# apache stop  
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName  
ERRLOG: [Tue Feb 15 11:45:40 2011] [notice] caught SIGTERM, shutting down

然后我开始它：

CMDLIN: root@bunny:/etc/apache2# apache start
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
ERRLOG: [Tue Feb 15 11:46:09 2011] [notice] Apache/2.2.14 (Ubuntu) proxy_html/3.0.1 mod_perl/2.0.4 Perl/v5.10.1 configured -- resuming normal operations

然后我重新启动它：

CMDLIN: root@bunny:/etc/apache2# apache restart
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
ERRLOG: [Tue Feb 15 11:46:15 2011] [notice] SIGHUP received.  Attempting to restart

然后我换回目录来测试它使用我的shell路径的理论

CMDLIN: root@bunny:/etc/apache2# cd ..
CMDLIN: root@bunny:/etc# apache restart
APWARN: apache2: Syntax error on line 33 of /etc/apache2/apache2.conf: Include directory 'mods-enabled' not found
ERRLOG: apache2: Syntax error on line 33 of /etc/apache2/apache2.conf: Include directory 'mods-enabled' not found

看起来像迄今为止...还挺..

CMDLIN: root@bunny:/etc# apache restart
APWARN: apache2: Syntax error on line 33 of /etc/apache2/apache2.conf: Include directory 'mods-enabled' not found

仍然看起来像，但这次没有记录错误。改回apache目录并重试

CMDLIN: root@bunny:/etc# cd apache2/
CMDLIN: root@bunny:/etc/apache2# apache restart
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
APWARN: httpd not running, trying to start
ERRLOG: [Tue Feb 15 11:46:30 2011] [warn] pid file /var/run/apache2.pid overwritten -- Unclean shutdown of previous Apache run?
ERRLOG: [Tue Feb 15 11:46:30 2011] [notice] Apache/2.2.14 (Ubuntu) proxy_html/3.0.1 mod_perl/2.0.4 Perl/v5.10.1 configured -- resuming normal operations

嗯，看起来就是这样，对吧？至于为什么...不知道...

另一个好的重启，除了那个DNS的东西...

CMDLIN: root@bunny:/etc/apache2# apache restart
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
ERRLOG: [Tue Feb 15 11:46:36 2011] [notice] SIGHUP received.  Attempting to restart

到目前为止这么好......等等......糟糕，这出现在日志中，而我没有改变目录，而Apache正在尝试启动，而是关闭。

ERRLOG: apache2: Syntax error on line 33 of /etc/apache2/apache2.conf: Include directory 'mods-enabled' not found

我去重新启动它，然后...

CMDLIN: root@bunny:/etc/apache2# apache restart
APWARN: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
APWARN: httpd not running, trying to start
ERRLOG: [Tue Feb 15 11:46:45 2011] [warn] pid file /var/run/apache2.pid overwritten -- Unclean shutdown of previous Apache run?
ERRLOG: [Tue Feb 15 11:46:45 2011] [notice] Apache/2.2.14 (Ubuntu) proxy_html/3.0.1 mod_perl/2.0.4 Perl/v5.10.1 configured -- resuming normal operations

它已经回来了。我很困惑。

我不知道为什么会发生这种情况，它没有任何意义，它应该这样做。我的直觉告诉我，它不知道怎样才能找到正确的道路，并且期望MODS能够因为某种原因与我的位置相关，在我的身体里......而这种本身就会变得毛茸茸的，它变得更糟当Apache在运行过程中关闭它自己的同一个“错误”

这是我的httpd.conf：

<Location ~ "/ws/?.*$">
    SetHandler perl-script
    PerlResponseHandler Webservices::Qmedtrix
</Location>

<Directory /var/www>
    Options +ExecCGI +Includes
</Directory>

<Directory /usr/share>
    Options ExecCGI FollowSymlinks Indexes
</Directory>

ProxyPass /group http://localhost:8080/group
ProxyPassReverse /group http://localhost:8080/group

这是我的apache2.conf：

LockFile ${APACHE_LOCK_DIR}/accept.lock

这是我的默认虚拟域名：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DirectoryIndex index.shtml index.html

    DocumentRoot /var/www
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /var/www/>
        Options Indexes FollowSymLinks MultiViews +Includes +ExecCGI
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog /var/log/apache2/access.log combined

</VirtualHost>

和我的envars文件：

#unset HOME
# I have tried the above line enabled and not, no difference.

if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
        SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
        SUFFIX=
fi

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX
export LANG=C
export LANG

我很难过。

任何想法发生了什么？

我在KVM虚拟客户端也遇到了完全相同的问题。对我来说，解决方案是取消注释以下行：

#ServerRoot“/ etc / apache2”

希望这可以帮助下一个开始想知道为什么他必须在“/ etc / apache2”目录中运行“apache2ctl start”才能成功的人;）

apachectl是一个bash脚本。您可能需要将该行为的错误报告提交给Ubuntu BTS。

您应该删除/etc/envvars文件中的行：

#unset HOME
# I have tried the above line enabled and not, no difference.

if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
        SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
        SUFFIX=
fi

删除所有这些。

然后编辑你的envvars以删除你的$后缀，以便你的最终文件看起来像这样：

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2.pid
export APACHE_RUN_DIR=/var/run/apache2
export APACHE_LOCK_DIR=/var/lock/apache2
export APACHE_LOG_DIR=/var/log/apache2
export LANG=C
export LANG

我和你的问题完全一样。并在玩envvars后修复它。
