mysql-proxy启动时可能会碰到libevent-1.4.so.2不能打开的问题，打开shell，运行LD_DEBUG=libs ./mysql-proxy -h会得到mysql-proxy运行时需要到哪里去寻找所需的包，改问题的解决办法是建立libevent到指定目录的软连接。
mysql-proxy服务启动 vi /etc/init.d/mysql-proxy
#!/bin/sh
#chkconfig:2345 80 20
#description:mysql-proxy
export LUA_PATH=/usr/local/share/mysql-proxy/?.lua

killall mysql-proxy
'restart')
if $0 stop ; then
$0 start
else
echo "retart failed!!!"
exit 1
fi
esac
exit 0
chkconfig --add mysql-proxy
chomod +x /etc/init.d/mysql-proxy
/etc/init.d/mysql-proxy start|stop|restart
得到mysql-proxy服务的启动，关闭和重启。
