配置 nginx server 出现nginx: [emerg] "root" directive is duplicate in /etc/nginx/server/blogs.conf:7

在配置nginx 虚拟机时，执行

sudo /usr/sbin/nginx -t

报下面的错误：

nginx: [emerg] "root" directive is duplicate in /etc/nginx/server/blogs.conf:
nginx: configuration file /etc/nginx/nginx.conf test failed

错误原因是：在配置文件时，访问路径设置了两个，重复配置webroot路径导致，去掉一个就可以了。

server {
        listen  default_server;

        #root /usr/share/nginx/html/;去掉这行
        index index.html index.htm;
        # Make site accessible from http://localhost/
        root /home/wangkongming/webroot/blogs;

        index index.html index.htm;
        server_name blogs.local;

        location / {
                try_files $uri $uri/ =;
        }

        location ~ \.php$ {
            fastcgi_pass 127.0.0.1:;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }
        access_log /data/logs/blogs/access.log;
        error_log /data/logs/blogs/error.log;
