varnish后端VCC-编译器失败

Question

我想在我的SX服务器前面添加一个varnish代理，我有两个shows ip:192.168.0.100 ip: 192.168.0.101都可以在lan中工作，但重新启动varnish时显示编译错误

nano /etc/varnish/default.vcl

# define our first nginx server
backend nginx01 {
    .host = "192.168.0.100";
    .port = "80";
}

# define our second nginx server
backend nginx02 {
    .host = "192.168.0.101";
    .port = "80";
}

# configure the load balancer
director nginx round-robin {
    { .backend = nginx01; }
    { .backend = nginx02; }
}

# When a request is made set the backend to the round-robin director named nginx
sub vcl_recv {
    set req.backend = nginx;
}

重新启动varnish时显示错误

root@Sproxy:~# service varnish restart
Message from VCC-compiler:

Answer 1

尽管@Redithion给出了这个例子，但Varnish 4.0的正确配置似乎是：

vcl 4.0;

import directors;

backend nginx01 {
    .host = "192.168.0.100";
    .port = "80";
}

backend nginx02 {
    .host = "192.168.0.101";
    .port = "80";
}

sub vcl_init {
    new nginx = directors.round_robin();
    nginx.add_backend(nginx01);
    nginx.add_backend(nginx02);
}

sub vcl_recv {
    set req.backend_hint = nginx.backend();
}

Answer 2

您似乎使用的是Varnish 4.0。在此版本中，控制器已被moved to VMODs

这是一个基于我从here获得的示例

vcl 4.0;

# define first nginx server
backend nginx01 {
    .host = "192.168.0.100";
    .port = "80";
}

# define second nginx server
backend nginx02 {
    .host = "192.168.0.101";
    .port = "80";
}

sub vcl_init {
    new cluster1 = directors.round_robin();
    cluster1.add_backend(nginx01, 1.0);
    cluster1.add_backend(nginx02, 1.0);
}

sub vcl_recv {
    set req.backend_hint = cluster1.backend();
}

提示：不要忘记“vcl4.0；”语句！
