无法在端口 80 CentOS v7.9.2009 kvm [ns] 上启动 Varnish - 错误：-a 参数 localhost:8443 和 localhost:8443 具有相同的地址

Question

请你们帮忙。我之前安装了 Varnish &工作如下： https://computingforgeeks.com/install- varnish-cache-for-apache-nginx-on-centos/。最近已经不行了。不知道为什么。

[root@ns ~]# systemctl status varnish.service
● varnish.service - Varnish Cache, a high-performance HTTP accelerator

Mar 02 08:41:43 [nameserver url] systemd[1]: varnish.service failed.

我猜问题是：

Mar 02 08:41:42 [nameserver url] varnishd[22134]: Error: -a arguments localhost:8443 and localhost:8443 have same address

运行 netstat -ltnp 来检查端口：8443

[root@ns ~]# netstat -ltnp

但我发现没有这样的端口。尝试重新启动 Apache、服务器和清漆。没有帮助。大家有遇到过类似的问题吗？我该如何解决这个问题？先感谢您

Answer 1

我使用以下命令运行默认的清漆服务配置文件：

$ sudo vi /etc/systemd/system/multi-user.target.wants/varnish.service

ExecStart=/usr/sbin/varnishd \
                  -a :80 \
                  -a localhost:8443,PROXY \
                  -p feature=+http2 \
                  -f /etc/varnish/default.vcl \
                  -s malloc,256m
        ExecReload=/usr/sbin/varnishreload

我认为问题在于这个。移除后清漆再次发挥作用。但我不确定它是否会在其他地方造成麻烦。

              -a localhost:8443,PROXY \
