我在我的Ubuntu 14.04中使用php-fpm 5.5.9配置Apache 2.4.9。我想要的是为php-fpm请求制作一个平衡器，但它会引发以下错误：
AH01071: Got error 'Primary script unknown\n'
当我尝试访问我的php文件时。代理平衡器似乎没有抓住ProxyPassMatch传递给它的文档根目录。我使用UDS让apache访问php-fpm套接字，而不是使用网络tcp。
如果我没有平衡器配置它，一切正常。
ProxyPassMatch ^/(.*\.php(/.*)?)$ unix:/var/run/php5-fpm.sock1|fcgi://./var/www/html
ProxyPassMatch ^/(.*\.php(/.*)?)$ balancer://localhost/var/www/html
<Proxy balancer://localhost/>
BalancerMember unix:/var/run/php5-fpm.sock1|fcgi://localhost:9001
BalancerMember unix:/var/run/php5-fpm.sock2|fcgi://localhost:9002
BalancerMember unix:/var/run/php5-fpm.sock3|fcgi://localhost:9003
BalancerMember unix:/var/run/php5-fpm.sock4|fcgi://localhost:9004
</Proxy>
这是平衡器的配置日志：

tcpdump在这种情况下可能会有所帮助。
tcpdump port 9001 -A | strings
它将向您显示apache尝试在哪里找到主文件
