项目部署在CentOS的小问题，项目403

今天访问以前的网站项目，突然发现无法访问了，并且报错为403.
但是，tomcat自带的项目是能够访问的
tomcat--log

找了半天原因，想到的可能原因有两个
1、原来数据库的内容被修改过，部分数据可能出现冲突或是不完整
2、tomcat在CentOS上的部分权限不够
之后整理了数据库数据，给tomcat了777的权限

[root@Fleischer local]# ls
aegis  cloudmonitor  games    lib    libexec  redis  share  tomcat
bin    etc           include  lib64  nginx    sbin   src
[root@Fleischer local]# chmod -R 777 tomcat

之后就能够正常运行了，特此记录。
