为什么当文件error.log不存在时Apache停止

为什么某些路径设置错误或我的情况下Apache服务器停止工作-文件不存在?这是我的配置:

<VirtualHost *:80>
    ServerName toma-coreshop.webbuild.com
    DocumentRoot /home/projects/toma/toma-coreshop

    <Directory /home/projects/toma/toma-coreshop>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
ErrorLog /home/projects/toma/toma-coreshop/logs/error.log
</VirtualHost>

现在error.log文件不存在,整个服务器掉线了。其他域也不起作用。为什么会这样呢?也赞赏任何有用的链接。预先谢谢你!

首先,如果errorlog指令中指定的目录路径存在,Apache 2.4将创建一个日志文件。

仅当目录丢失时,才会出现此问题。

在Apache(重新)启动期间,它将检查配置中是否有错误。在修改配置时出现错误,但是Apache没有重新启动,因此仍然可以运行时,可以手动执行以下操作:

# apachectl -t
(2)No such file or directory: AH02291: Cannot access directory '/var/www/example.com/nologs/' for error log of vhost defined at /etc/httpd/conf/plesk.conf.d/vhosts/example.com.conf:10
AH00014: Configuration check failed

Strace显示,在重新启动期间,Apache检查所有指定的错误日志目录:

# strace /usr/sbin/httpd
...
stat("/etc/httpd/logs/", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
...
stat("/var/www/example.com/nologs/", 0x7ffff84f3140) = -1 ENOENT (No such file or directory)
write(2, "(2)No such file or directory: AH"..., 203(2)No such file or directory: AH02291: Cannot access directory '/var/www/example.com/nologs/' for error log of vhost defined at /etc/httpd/conf/plesk.conf.d/vhosts/example.com.conf:10
) = 190
write(2, "AH00014: Configuration check fai"..., 36AH00014: Configuration check failed
) = 36

看来,能够访问错误日志对于Apache正常执行非常重要。同时,Apache不会随意创建日志目录的完整路径。
