遇到一个问题， nginx代理php请求到php-fpm, 发现不知道是nginx的问题， 还是php-fpm的问题. 想通过bash直接调试php-fpm.

查了下, 发现是可以。记录下。

debian/ubuntu 下安装

1
# apt-get install libfcgi0ldbl

centos/redhat 下安装

1
#  yum --enablerepo=epel install fcgi

编写脚本测试

# cat > php-fpm.sh <<EOF
    #!/bin/bash
    SCRIPT_FILENAME=/var/www/html/site/index.php \
    REQUEST_URI=/api/user/wealth.json \
    QUERY_STRING=uid=121923823&_=1828188212 \
    REQUEST_METHOD=GET \
    cgi-fcgi -bind -connect php-fpm-host:9000
  EOF

测试

1
# bash -x php-fpm.sh

这个就是nginx代理过去的请求是原理是一样的, nginx传的变量会更多点。
