测试keepalived  重启服务IP能否自动飘

关闭nginx 关闭，是否自动开启。

 

 

#-----------------nginx发布静态文件-------------

 

有一个A网站，访问的话会重定向跳转到B网站上，在A网站的nginx配置文件中配置的有如下：

location / {
   rewrite ^/(.*)    http://B/$1   redirect;
}

现在有一个需求，就是在小程序中需要给A网站验证一个txt文件，正常做法是要把这个文件上传到B网站才行，但是B网站无法进行操作，只能是在A上面操作，所以考虑直接使用写死的方式进行：

location /EJyhBr8IAO.txt{
        alias /opt/verify/EJyhBr8IAO.txt;
}

示例：

location /WW_verify_IPbZZJDkYw0tKQ7m.txt{
alias /usr/local/nginx/html/WW_verify_IPbZZJDkYw0tKQ7m.txt;
}

把txt文件上传到指定目录，完美解决。
