我在RHEL7系统上。我是haproxy的新手。我想我有一些问题。这是我要使用的地址。
[root@haproxy-el7-001 haproxy]# grep 1936 /etc/haproxy/haproxy.cfg
bind 10.29.103.39:1936
这是我的haproxy.cfg周围的样子...
listen haproxy_stats
bind 10.29.103.39:1936
mode http
stats enable
stats hide-version
stats realm Haproxy\ Statistics
stats uri /
stats auth xxxxx:xxxxx
我没有要进行负载平衡的其他服务,但是我仍然希望能够像这样查看统计信息...
[root@haproxy-el7-001 haproxy]# wget http://10.29.103.39:1936

这是输出,ip a
我没有看到列出的vip 10.29.103.39。

我在这里做错了什么?
我正在使用使用Puppetlabs HAProxy模块的内部Puppet模块。木偶代码确实看起来像这样...
keepalived::instance { 'haproxy-vip':
advert_int => '1',
priority => "$priority",
state => "$state",
virtual_router_id => "$vrouter_id",
interface => 'eth0',
virtual_ips => [ $controller_vip, $swift_vip ],
track_script => [ 'check_haproxy' ],
}
...并且此代码未在RHEL7上进行测试。RHEL7接口名称可能有所不同。在我的RHEL7系统上,主要网卡称为“ ens160”。我将人偶代码更改为使用事实“接口”,如下所示...
$allnics = split( $interfaces, "," )
$interface = $allnics[0]
keepalived::instance { 'haproxy-vip':
advert_int => '1',
priority => "$priority",
state => "$state",
virtual_router_id => "$vrouter_id",
interface => "$interface",
virtual_ips => [ $controller_vip, $swift_vip ],
track_script => [ 'check_haproxy' ],
}
