如何在Piranha环境下做Socket应用服务的负载

cnhome_2008

感觉lvs是可以为socket做均衡负载的，只要调整一下monitor script脚本


可是最近一直没能做成功。

我做了个shell脚本如下

#!/bin/sh

if nc $1 1111 -w 3 -z;then
    echo "OK"
else
    echo "FAIL"
fi

可以检测1111端口

然后把monitor script上改为
Sending Program ="/opt/test.sh %h"
Send 不需要
Expact="OK"

realserver一直没有被检测到，不知道我这样做对不对，错在哪里。请做过的有经验的朋友指点指点。

补充一下错误日志

日志显示是expect值不对。你把手动运行命令的结构放上来，然后把配置文件放上来看看？

cnhome_2008

我直接用的这个脚本


#!/bin/sh

if nc $1 1111 -w 3 -z;then
    echo "OK"
else
    echo "FAIL"
fi

send program里边

检测对端1111端口是否存在


当然也可以用telnet,登陆

[root@localhost ~]# telnet xxx.xxx.xxx.xxx 1111
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx(xxx.xxx.xxx.xxx).
Escape character is '^]'.
+ Input login password please:

如果输入内容回车则显示一下提示:

+ Authentication succeeded! Input monitoring command:

用telnet那种方式的我一直没有配通，所以采用了第一种检测端口的脚本

cnhome_2008

[root@localhost opt]# ./test.sh xxx.xxx.xxx.xxx
Connection to xxx.xxx.xxx.xxx 1111 port [tcp/lmsocialserver] succeeded!
OK

这个是shell脚本的测试

cnhome_2008

改了一下配置

Send Program 为空
Sending "\n"
Expect "*"

测试通过

johnyo

[root@localhost opt]# ./test.sh xxx.xxx.xxx.xxx
Connection to xxx.xxx.xxx.xxx 1111 port [tcp/lmsocialserver] succeeded!
OK

如果是这样，expect 应该就是Connection to xxx.xxx.xxx.xxx 1111 port [tcp/lmsocialserver] succeeded!
OK
