nat123在centos下不稳定,掉线的处理办法

##关闭nat123相关进程
ps -ef |grep nat123linux |awk '{print $2}'|xargs kill -9
##进入nat123执行目录
cd  /root
##启动nat123相关进程
nohup mono /root/nat123linux.sh service >/root/out_put.log 2>&1 &

//1.配置nat123目录和执行文件和日志文件
$nat123_path = '/root';
$nat123_exec = $nat123_path . DIRECTORY_SEPARATOR . 'nat123linux.sh';
$nat123_out_put = $nat123_path . 'out_put.log';

//2.重置所在目录
chdir($nat123_path);

//3.关闭运行的Nat123进程
$stop_cmd = "ps -ef |grep nat123linux |awk '{print $2}'|xargs kill -9";
$res1 = exec($stop_cmd, $output, $return);

//4.重新启动Nat123进程
$start_cmd = "nohup mono $nat123_exec service >{$nat123_out_put} 2>&1 &";
$res2 = exec($start_cmd, $output, $return);
