3.1.2
【问题描述】
采用obd部署三台物理服务器，CPU 64core 内存128GB，三台物理服务器均配置完毕免密登录、防火墙、selinux、时钟同步，检查如下：
[admin@fompdb1 ~]$ ntpstat
synchronised to local net (127.127.1.0) at stratum 9
time correct to within 11 ms
polling server every 64 s
[admin@fompdb1 ~]$ ssh fompdb2 ntpstat
synchronised to NTP server (192.168.5.140) at stratum 10
time correct to within 45 ms
polling server every 1024 s
[admin@fompdb1 ~]$ ssh fompdb3 ntpstat
synchronised to NTP server (192.168.5.140) at stratum 10
time correct to within 39 ms
polling server every 1024 s
obd配置文件如下：
