nginx使用fastcgi模式时，要启动多个cgi进程才能正常使用drupal

Posted 2023-04-10

参考技术A 安装drupal时，使用了nginx+fastcgi模式。
一开始只起了一个php-cgi进程，结果发现进入主界面后，每次点“配置”后，系统就会阻塞，直到超时后报错“PDOException:
SQLSTATE[23000]:
Integrity
constraint
violation:
1048
Column
'uid'
cannot
be
null",
这里应该是$uid取值为空。
首先到db里看了user表和session表，发现有内容。没办法又根据关键字找了一圈代码，也没有发现有用的线索。后来在群里经过好心人的提醒，cgi处理进程要启多个，因为“有些程序会curl,访问自己,系统就会卡死,或通信失败”。然后又启了1个php-cgi（现在有2个），问题解决。
这里附上nginx.conf里配置多个fastcgi的指令吧，希望能给遇到类似问题的同学一点帮助：

sh 使用Nginx和MySQL编译并将php 5.3.27安装到FastCGI模式
