一键部署默认提供一个简单的单后端配置文件
vcl 4.1;
backend default {
.host = "127.0.0.1"; // 替换为你的Web服务器IP
.port = "8080"; // 替换为你的Web服务器端口
}
sub vcl_recv {
# 在这里添加请求处理逻辑
return (hash);
}
sub vcl_backend_response {
# 在这里添加后端响应处理逻辑
set beresp.ttl = 10m; # 设置缓存时间为10分钟

多后端负载均衡
vcl 4.1;

# 定义多个后端服务器

.port = "8080"; # 端口
.max_connections = 200; # 最大连接数限制
}
backend server2 {
.host = "192.168.1.11"; # 第二个后端服务器IP
.port = "8080";
.max_connections = 200;
}
backend server3 {
.host = "192.168.1.12"; # 第三个后端服务器IP
.port = "8080";
.max_connections = 200;
}
# 负载均衡算法
sub vcl_init {
new lb = directors.round_robin(); # 轮询算法

# 可选：根据后端服务器设置不同的缓存标识
