禅道PMS 在lnmp下的安装问题

禅道PMS（zentaoPMS）是一个优秀的国产开源项目管理软件。官方提供了lamp一键安装包，但是我们常常已经有了lnmp环境，那么需要直接从源码包安装zentaopms。

最近帮朋友安装zentaopms，安装了标准的lnmp，安装zentao时却碰到了问题：

经过google，问题是php参数session.save_path = "/var/lib/php/session"

目标目录不存在，或者php-fpm没有写权限，解决办法：

（假设我们以nginx身份运行php-fpm）

mkdir -p /var/lib/php/session
chown nginx:nginx /var/lib/php/session
