varnish 4
WordPress 4.4
中有多个主机,我遇到503错误。
虚拟服务器, server_1 和 server_2 。 (我只复制一个,因为两者的VS相同,x等于服务器编号)。
server {
listen 81;
server_name server_x.localhost;
root /var/www/server_x;

当我尝试在任何服务器中输入时,我得到 503后端提取失败,但当我通过单独的服务器(http://server_1.localhost
和http://server_2.localhost
进入)时返回200
代码。
答案 0 :(得分:0)
Varnish通过GET /测试后端健康。而后端的IP是127.0.0.1 尝试登录您的服务器并通过控制台Web浏览器“get /”,如elinks(apt-get install elinks或yum install elinks,如果您没有): elinks http://127.0.0.1:81 当我在我的服务器上完成该操作时,遇到同样的问题,我注意到127.0.0.1没有默认网页,而Varnish收到错误404并将后端标记为坏。 希望这会有所帮助
