Arch Linux apache在启动崩溃时启动

内核恐慌

我安装了带有Arch Linux的Raspberry Pi B +,并且在启动时,Apache Web服务器无法启动:

[xxx@rpi ~]# systemctl status -l httpd
* httpd.service - Apache Web Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Thu 1970-01-01 01:00:23 CET; 45 years 0 months ago
  Process: 177 ExecStart=/usr/bin/apachectl start (code=exited, status=134)

Jan 01 01:00:23 rpi apachectl[177]: Assertion 'canonical' failed at src/nss-myhostname/nss-myhostname.c:204, function fill_in_hostent(). Aborting.
Jan 01 01:00:23 rpi apachectl[177]: /usr/bin/apachectl: line 79:   185 Aborted                 (core dumped) $HTTPD -k $ARGV
Jan 01 01:00:23 rpi systemd[1]: httpd.service: control process exited, code=exited status=134

[xxx@rpi ~]#

但是,如果从ssh终端重新启动apache(在系统重新启动并ssh登录之后),则该apache已正确运行:

[xxx@rpi ~]# systemctl restart httpd && systemctl status -l httpd
* httpd.service - Apache Web Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

           |-429 /usr/bin/httpd -k start
           `-430 /usr/bin/httpd -k start

发生了什么(正在运行Linux octopustest 3.12.35-1-ARCH #1 PREEMPT Tue Dec 23 07:14:51 MST 2014 armv6l GNU/Linux内核和Apache/2.4.10)?

点子

有一个非常简单的解决方案对我有用。它需要编辑/ etc / hosts文件,如果可能的话,总是避免这样做,但是它解决了我遇到的所有问题。如果有人尝试访问Internet并获取信息(包括Apache,Eclipse和其他应用程序),则会发生此错误。有时,这是由应用程序本身的错误引起的,但也可能是本地问题,当您的/ etc / hosts文件缺少程序所需的某些元素时,会导致该问题。

请注意,您将需要管理员访问权限(或成为该sudoers的一部分)才能完成其中一些步骤。

首先,使用以下命令打开hosts文件:sudo nano /etc/hosts您的主机文件应类似于以下内容,它是我的直接副本:

# 
# /etc/hosts: static lookup table for host names
#

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1   localhost.localdomain   localhost BEN-PC-ARCH
::1         localhost.localdomain   localhost BEN-PC-ARCH
# End of file

请注意,除了将127.0.0.1反映到localhost.localdomain之外,还有第二行执行相同的操作。/etc/hosts无论出于何种原因,将此文件添加到文件中都可以解决该问题。
