socat

测试下来,socat要比haproxy稳定,速度快,推荐使用

nohup socat -T 600 TCP4-LISTEN:1883,reuseaddr,fork TCP4:54.223.43.113:1883  >> socat1883.log 2>&1 &

yum install -y haproxy

# 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

chroot /var/lib/haproxy
