我正在使用 pgpool，当我运行时：
sudo pgpool -f pgpool.conf -F pcp.conf -n
它只记录一行并继续等待......：
2014-10-09 13:27:42 LOG: pid 28626: wd_chk_setuid: ifup[/sbin/ifconfig] doesn't have setuid bit
我使用 Vagrant VM 在 Ubuntu-14.04 上安装了 pgpool-II-3.3.4。
我的 pgpool.conf 中的看门狗和心跳配置：

我也遇到了同样的问题。我解决了一些问题，但又遇到了其他问题
我这样做：
mkdir /home/apache
cp /sbin/ifconfig /home/apache
cp /usr/sbin/arping /home/apache
接下来必须添加 setuid 位：
chmod ugo+s /home/ifconfig
chmod ugo+s /home/arping
但我收到以下信息：
[root@Fil-pgp apache]# /pgpool/bin/pgpool
2014-10-28 15:31:33 LOG: pid 4053: wd_chk_setuid all commands have setuid bit
2014-10-28 15:31:33 LOG: pid 4053: watchdog might call network commands which using setuid bit.
有什么建议吗？
