求帮助，Linux安装Nginx后改了根目录报403

没改之前还有欢迎。。。。。啥的改了之后
我修改的是下面三个地方，原来的都是html;


除了报403，里面的图片可以看
关于权限，我都设置了777

我的意思是先把：
location / {
root /home/ftpuser/www;
index index.html index.htm;
}
还原成：
location / {
root html;
index index.html index.htm;
}
再新增新增一个location:
location ~ .*.(gif|jpg|jpeg|png)$ {
root /home/ftpuser/www;
index index.html index.htm;
}

注意路径的拼接，你可以看看nginx的error.log中会有最后拼接访问的路径，这样就知道你修改路径后，为什么拼接的路径不正确了

我没记错的话，root后面的目录是从Ng的安装根目录开始算起。照你这个配置，应该会找到ng的安装根目录/home/ftpuser/www。不知道说的对不对

抱歉刚才没看懂你的问题。你是说你改了配置之后，图片可以正确访问，但是其他请求报错是吧？我看你把所有请求全部指向了/home/ftpuser/www
而这个文件夹里面只放了图片，所以你能正确访问图片，其他请求会报错。
这里应该改一下：
location / {
root /home/ftpuser/www;
index index.html index.htm;
}
先还原。任何新增一个location:
location ~ .*.(gif|jpg|jpeg|png)$ {
root /home/ftpuser/www;
index index.html index.htm;
}

         #access_log  logs/host.access.log  main;

        location / {
            root   /home/ftpuser/www;
            index  index.html index.htm;
        }
    location ~ .*.(gif|jpg|jpeg|png)$ {
        root   /home/ftpuser/www;
        index  index.html index.htm;
    }
        #error_page  404              /404.html;

改成这样么？

我的想法就是输入http://192.168.44.128/ 后显示那个Nginx的欢迎页面
