varnish round robin director 不选择后端
varnish round robin director not picking backends
我有 varnish 设置，有 2 个后端服务器和循环控制器。
这 2 个后端在 varnishstat 和 varnishadm 中显示为健康。
varnishadm 输出：
Backend name Admin Probe
boot.app1 probe Healthy 5/5
boot.app2 probe Healthy 5/5
VCL 配置：
probe ping {
.interval = 5s;
.timeout = 1s;
.threshold = 3;
.window = 5;
.url = "/ping";
}
backend app1 {
.host = "app-1.example.com";
.port = "80";
.probe = ping;
}
backend app2 {
.host = "app-2.example.com";
.port = "80";
.probe = ping;
}
new application_servers = directors.round_robin();
application_servers.add_backend(app1);
application_servers.add_backend(app2);
set req.backend_hint = application_servers;
varnishstat 输出：
VBE.boot.app1.happy ffffffffff VVVVVVVVVVVVVVVVVVVVVVVV
VBE.boot.app1.bereq_hdrbytes 66.17K 0.00 91.00 0.00 0.00 0.00
VBE.boot.app1.beresp_hdrbytes 76.72K 0.00 106.00 0.00 0.00 0.00
VBE.boot.app1.beresp_bodybytes 11.91M 0.00 16.50K 0.00 0.00 0.00
VBE.boot.app1.conn 251 0.00 . 251.00 251.00 251.00
VBE.boot.app1.req 251 0.00 . 0.00 0.00 0.00
VBE.boot.app2.happy ffffffffff VVVVVVVVVVVVVVVVVVVVVVVV
您可以从 varnishstat 命令中看到，流量似乎只发送到循环配置中的第一台服务器。除了 .happy
之外，app2 服务器没有其他行
有什么想法会导致主管每次都选择第一台服务器吗？

通常您会调用 .backend() 以作为 backend_hint 传递。
req.backend_hint = application_servers.backend();
我认为如果不这样做会出现语法错误，但在您使用 director 实例作为后端的情况下，它可能只是 returns 第一个后端。
set req.backend.hint = application_servers.backend(); 这行在你的 vcl 中的什么位置？
应该是sub vcl_recv
中的第一行
此外，探测器 window 是什么样子的？你列出了 'happy' 但如果你 运行 varnishstat -1 你应该看到完整的探测 window.
为了帮助进一步调试它，请在您的 vcl 中放入一些系统日志调用。使用 vmod std 或将它们内联
C{
syslog(LOG_ERR, "I am at line X in my vcl");
}C
您需要开启内联C选项。在 Varnish 4 中它默认关闭。
发现问题与用于部署清漆的 puppet 模块有关。
puppet 模块未在 vcl 文件中包含相关模板。
我已经向 GitHub 提交了一个拉取请求来解决这个问题
我有 varnish 设置，有 2 个后端服务器和循环控制器。
这 2 个后端在 varnishstat 和 varnishadm 中显示为健康。
varnishadm 输出：
Backend name Admin Probe
boot.app1 probe Healthy 5/5
boot.app2 probe Healthy 5/5
VCL 配置：
probe ping {
.interval = 5s;
.timeout = 1s;
.threshold = 3;
.window = 5;
.url = "/ping";
}
backend app1 {
.host = "app-1.example.com";
.port = "80";
.probe = ping;
}
backend app2 {
.host = "app-2.example.com";
.port = "80";
.probe = ping;
}
new application_servers = directors.round_robin();
application_servers.add_backend(app1);
application_servers.add_backend(app2);
set req.backend_hint = application_servers;
varnishstat 输出：

VBE.boot.app2.happy ffffffffff VVVVVVVVVVVVVVVVVVVVVVVV
您可以从 varnishstat 命令中看到，流量似乎只发送到循环配置中的第一台服务器。除了 .happy
之外，app2 服务器没有其他行有什么想法会导致主管每次都选择第一台服务器吗？

通常您会调用 .backend() 以作为 backend_hint 传递。
req.backend_hint = application_servers.backend();
我认为如果不这样做会出现语法错误，但在您使用 director 实例作为后端的情况下，它可能只是 returns 第一个后端。
set req.backend.hint = application_servers.backend(); 这行在你的 vcl 中的什么位置？
应该是sub vcl_recv
此外，探测器 window 是什么样子的？你列出了 'happy' 但如果你 运行 varnishstat -1 你应该看到完整的探测 window.
为了帮助进一步调试它，请在您的 vcl 中放入一些系统日志调用。使用 vmod std 或将它们内联
C{
syslog(LOG_ERR, "I am at line X in my vcl");
}C
您需要开启内联C选项。在 Varnish 4 中它默认关闭。
发现问题与用于部署清漆的 puppet 模块有关。
puppet 模块未在 vcl 文件中包含相关模板。
我已经向 GitHub 提交了一个拉取请求来解决这个问题
