在CentOS 7.2 新增了nginx官方的yum來源，使用yum install nginx 安裝的nginx/1.10.2
安裝完成後我關閉了系統防火牆，預設站點可以正常訪問，我又添加了另一個虛擬主機設定文件，內容如下：
server {
listen 80;
server_name idas.it;
root /home/html;
index index.html index.php;
# location / {
# try_files $uri $uri/ /index.php?$query_string;
# }
location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}目錄權限如下：

-rwxrwxr-x. 1 root root 612 Nov 12 15:24 index.html權限都給了，但存取還是403 Forbidden，以下是nginx的錯誤日誌：

求老司機帶路！ ！ ！ ！ ！
可以試試是否是SElinux沒關導致的，可以使用以下命令關閉：
好像跟什麼安全策略有關，透過軟連線應該可以解決，ln -s /var/nginx/html /home/html
