socat

测试下来，socat要比haproxy稳定，速度快，推荐使用

{% highlight shell %} nohup socat -T 600 TCP4-LISTEN:1883,reuseaddr,fork TCP4:54.223.43.113:1883 >> socat1883.log 2>&1 & {% endhighlight %}

deprecated under here

haproxy

{% highlight shell %} yum install -y haproxy {% endhighlight %}

{% highlight shell %}

vi /etc/haproxy/haproxy.cfg

global # to have these messages end up in /var/log/haproxy.log you will # need to: # # 1) configure syslog to accept network log events. This is done # by adding the '-r' option to the SYSLOGD_OPTIONS in # /etc/sysconfig/syslog # # 2) configure local2 events to go to the /var/log/haproxy.log # file. A line like the following can be added to # /etc/sysconfig/syslog # # local2.* /var/log/haproxy.log # log 127.0.0.1 local2
