空白的augeas设置值失败

Question

当我设置值(augeas-0.10.0与pupy-2.7.11一起使用)时，我遇到了与空格，ex有关的问题。

...

changes => "set *[self::directive='FastCgiExternalServer']/arg '/usr/lib/cgi-bin/php5-fcgi -socket /var/run/php5-fpm.sock -pass-header Authorization'",
...

保存完之后，我得到了这个错误消息：

/augeas/files/etc/apache2/mods-available/fastcgi.conf/error = "put_failed"
/augeas/files/etc/apache2/mods-available/fastcgi.conf/error/path = "/files/etc/apache2/mods-available/fastcgi.conf/IfModule/directive"
/augeas/files/etc/apache2/mods-available/fastcgi.conf/error/lens = "/usr/share/augeas/lenses/dist/httpd.aug:76.18-77.49:"
/augeas/files/etc/apache2/mods-available/fastcgi.conf/error/message = "Failed to match \n    ({ /arg/ = /([^\001-\004\t\n \"']|\\\\\"|\\\\')+|\"([^\001-\004\n\"\\]|\\\\[^\001-\004\n])\"|'([^\001-\004\n'\\]|\\\\[^\001-\004\n])'/ }({ /arg/ = /([^\001-\004\t\n \"']|\\\\\"|\\\\')+|\"([^\001-\004\n\"\\]|\\\\[^\001-\004\n])\"|'([^\001-\004\n'\\]|\\\\[^\001-\004\n])'/ })*)?\n  with tree\n    { \"arg\" = \"/usr/lib/cgi-bin/php5-fcgi -socket /var/run/php5-fpm.sock -pass-header Authorization\" }"

我尝试过不同的方法来逃避这个值，但是每次尝试都以同样的错误失败了。我做错什么了？感谢任何有帮助的答案！

Answer 1

你有两个问题：

• 您的更改可能会创建一个没有父arg节点的directive节点，这在Httpd.lns镜头中是无效的；
• 您需要在值周围强制引号，因为它包含空格。

所以(使用augtool)：

# Make sure the directive exists
set directive[. = 'FastCgiExternalServer'] FastCgiExternalServer
# Set the argument
set directive[. = 'FastCgiExternalServer']/arg '"/usr/lib/cgi-bin/php5-fcgi -socket /var/run/php5-fpm.sock -pass-header Authorization"'

应该工作得更好。

"arg“实际上是一张清单。每一个论点都应列举如下：

defvar conf /files/etc/apache2/sites-available/foo
clear $conf/VirtualHost
set $conf/VirtualHost/arg "172.16.0.1:80"
set $conf/VirtualHost/directive "FastCgiExternalServer"
set $conf/VirtualHost/*[self::directive='FastCgiExternalServer']/arg[0] "/usr/lib/cgi-bin/php5-fcgi"
set $conf/VirtualHost/*[self::directive='FastCgiExternalServer']/arg[1] "-socket"
set $conf/VirtualHost/*[self::directive='FastCgiExternalServer']/arg[2] "/var/run/php5-fpm.sock"
set $conf/VirtualHost/*[self::directive='FastCgiExternalServer']/arg[3] "-pass-header"
set $conf/VirtualHost/*[self::directive='FastCgiExternalServer']/arg[4] "Authorization"

它生成以下文件：

<VirtualHost 172.16.0.1:80>
FastCgiExternalServer -socket /var/run/php5-fpm.sock -pass-header Authorization
</VirtualHost>
