[转]nginx虚拟目录(alias与root的区别)

今天配置awstats，awstats创建出的文件目录在/home/awstats下，在nginx中加入配置后狂报404，发现还是忽略了root和alias的区别，特将修改配置记录如下：

1.失败：server {
        server_name  test.com;
        charset utf-8,GB2312;
        index  index.html;

 

        location / {
        root html;
        access_log logs/access.log main;
         }

        location ~ ^/awstats/ {
        root  /home/awstats/;
        index  index.html;
        access_log off;
        error_log off;
        charset gb2312;
        }

 

2.失败: server {
        server_name  test.com;
        charset utf-8,GB2312;
        index  index.html;

 

        location / {
        root html;
        access_log logs/access.log main;
         }

        location ~ ^/awstats/ {
        alias  /home/;
        index  index.html;
        access_log off;
        error_log off;
        charset gb2312;
        }

 

3.成功: server {
        server_name  test.com;
        charset utf-8,GB2312;
        index  index.html;

 

        location / {
        root html;
        access_log logs/access.log main;
         }

        location ~ ^/awstats/ {
        alias  /home/awstats/;
        index  index.html;
        access_log off;
        error_log off;
        charset gb2312;
        }

 

4.成功: server {
        server_name  test.com;
        charset utf-8,GB2312;
        index  index.html;

 

        location / {
        root html;
        access_log logs/access.log main;
         }

        location ~ ^/awstats/ {
        root  /home/;
        index  index.html;
        access_log off;
        error_log off;
        charset gb2312;
        }

 

从以上例子很明显看出，还是对root和alias的概念搞混了~

1.      location ~ ^/awstats/ {
        root  /home/awstats/;
访问：http://test.com/awstats/ 实际访问的是/home/awstats/awstats/

 

2.      location ~ ^/awstats/ {
        alias  /home/

访问：http://test.com/awstats/ 实际访问的是/home/

 

3.      location ~ ^/awstats/ {                        #使用alias时目录名后面一定要加“/”
        alias  /home/awstats/;

访问：http://test.com/awstats/ 实际访问的是/home/awstats/

 

4.      location ~ ^/awstats/ {
        root  /home/;

访问：http://test.com/awstats/ 实际访问的是/home/awstats/
借用ayou老师的一句话：
一般情况下，在location /中配置root，在location /other中配置alias是一个好习惯
