关于ConnectionManager的配置(原)

 

服务器规划

Domain	IP	Description
imserver.p2pvpn.com	172.0.7.205	基于openfire的im server
cm1.p2pvpn.com	172.0.7.206	Connection Manager
cm2.p2pvon.com	172.0.7.205	Connection Manager
dns	172.0.7.206	dns服务器

 

 

 

 

 

 

一.配置dns服务器(这里的dns仅用于内网测试)

1.db.p2pvpn.com文件,用于正向解析

 

$TTL 604800
@ IN SOA dns.p2pvpn.com. root.p2pvpn.com. (
                1
                604800
                86400
                2419200
                604800 )
@ IN NS dns
dns IN A 172.0.7.206
imserver IN A 172.0.7.205
cm IN A 172.0.7.206
cm IN A 172.0.7.205

 

 

 

2.db.7.0.172文件用于反向解析(可有可无,一般反向解析很少用)

 

$TTL 604800
@ IN SOA dns.p2pvpn.com. root.p2pvpn.com. (
                1
                604800
                86400
                2419200
                604800 )
@ IN NS dns
206 IN PTR dns 

 

 

3.修改named.conf.local

 

zone "p2pvpn.com" {
        type master;
        file "/etc/bind/db.p2pvpn.com";
};

 

zone "7.0.172.in-addr.arpa" {
        type master;
        file "/etc/bind/db.7.0.172";
};

 

 

通过上面的配置, 只需要im client通过cm.p2pvpn.com这个domain就能轮询二台Connection Manager

dns配置注意:

sudo /etc/init.d/bind9 restart

sudo vim /etc/resolv.conf:指向本地dns.

 

二.配置Connection Manager

1.修改cm1的manager.xml

 

<?xml version="1.0" encoding="UTF-8"?>

注意:

由于使用grinder进行bosh的测试.所以开放了端口7071(默认是7070,但是该端口在我的机器上被占用)

 

三.启动imserver.在管理控制台-server settings-connection managers里面可以看到已经有cm1,cm2连接到imserver上.

 

四.设置grinder

1.修改one2one.py文件.
