我们在 Ubuntu 16.04.3 Server 上配置了 25 个虚拟主机,使用 apache2.4.18 和 PHP 7.0.22
apachectl configtest
给出语法 OK
对于虚拟主机从哪个特定时间开始显示默认页面,并没有明确的模式。
所有虚拟主机都写入自己的日志,当默认页面开始显示时,特定主机的日志就会静默。
service apache2 reload
解决问题。
我已经检查了 apache 错误和访问日志,没有什么异常,系统日志也没有什么异常。
知道哪里出了问题或者在哪里寻找错误吗?
Apache2.conf:
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.
# Global configuration
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"

# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.

# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5
# These need to be set in /etc/apache2/envvars

#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog ${APACHE_LOG_DIR}/error.log
#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#

Apache 站点配置,全部都是这种格式:
<VirtualHost *:80>
ServerName domainname.fi
ServerAlias www.domainname.fi
ServerAlias domainname.aliasdomain.domain.fi
ServerAdmin [email protected]
DocumentRoot /data/domainname.fi
ErrorLog /data/domainname.fi/logs/error.log
CustomLog /data/domainname.fi/logs/access.log combined
</VirtualHost>
我首先想到的是 apache2 中存在一些 bug,因此我对其进行了升级,但是问题并没有得到解决。
编辑:添加了conf文件以及我的第一个想法
答案1
根据定义,apache 将其读取配置时遇到的第一个虚拟服务器用作默认服务器。因此,默认服务器在未启动或重新加载的情况下不应更改。
Apache 将对默认服务器的访问记录到默认服务器的日志中,可能是 /var/log/apache2/access.log。当您遇到这种情况时,您可能会访问当时处于活动状态的默认服务器。如果您访问 /XXXYYYZZZ,您可能会执行类似
find /var/log/apache2 -type f | xargs grep /XXXYYYZZZ
找出 apache 在哪里记录它,并可能得到它使用的虚拟服务器的线索。
在配置完美的系统中,我无法想象默认条目如何“获取”对明确定义的虚拟服务器的访问权限。只是一些大胆的猜测:
不同的虚拟主机部分中有重叠的服务器名称/服务器别名条目
您的虚拟主机定义位于 25 个文件中,这些文件由 apache 读取。如果您的文件名中有非 ASCII 字符,则可能会根据 LANG 或 LC_xxx 设置以不同的顺序读取它们。执行每小时/每日/每月日志切换的脚本可能会使用启动脚本以外的其他语言设置。
您有一些配置异常,因此 apache 不会抱怨,但却可以不确定地工作。
也许您想发布您的配置,以便其他人可以检查它。
嗯,暂时没有其他想法。
