我正在尝试设置具有 2 个后端的清漆 (4) 服务器。但是，当我尝试使用 2 个不同的 URL 访问它时，它总是恢复到 server1 的后端。这是我的 .vcl 文件的相关部分。
后端服务器配置：
backend server1 {
.host = "127.0.0.1";
.port = "83";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}
backend server2 {
.host = "127.0.0.1";
.port = "84";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
}
和 vcl_recv 部分
import std;
# Respond to incoming requests.
sub vcl_recv {
if (req.method == "BAN") {
# Same ACL check as above:
if (!client.ip ~ purge) {
return(synth(403, "Not allowed."));
}
ban("req.http.host == " + req.http.host +
" && req.url == " + req.url);
# Throw a synthetic page so the
# request won't go to the backend.
return(synth(200, "Ban added"));
} else if (req.method == "PURGE") {
if (!client.ip ~ purge) {
return(synth(405,"Not allowed."));
}
return (purge);
} else if (req.method != "GET" && req.method != "POST" && req.method != "DELETE" && req.method != "PUT") {
return( synth(405, "Method not allowed"));
}
if (req.url ~ "^/piwik/piwik.php") {
set req.backend_hint = server1;
return(pass);
} else if (req.url ~ "^/piwik/piwik.js") {
set req.backend_hint = server1;
return(pass);
} else if (req.url ~ "^/piwik" ) {
# error 404 "Not found";
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~"/node/(\d+)/(.+)$") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~"/monitoring") {
# return( synth(404, "File not found"));
# set req.url = "/404-page-not-found";
return(pass);
} else if (req.url ~"^/user") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "^/admin") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "^/team") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "^/administer") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "/edit?$") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "/add?$") {
# return( synth(404, "File not found"));
set req.url = "/404-page-not-found";
} else if (req.url ~ "^(www\.)?server2.com$") {
set req.backend_hint = server2;
} else if (req.url ~ "^(www\.)?server1.com$") {
set req.backend_hint = server1.com;
}
如果我将以下语句添加到 vcl_recv 部分的底部，那么我可以访问 server2 的后端：
else {
set req.backend_hint = server2;
}
