Linux升级ntp，make时报错怎么办？急，在线等！！！！

根据你这个错误提示，可以看到是crypto模块里的函数定义出错，可能的原因是新版本ntp所用的这个模块版本比较新，你系统上的gcc可能不支持这个函数，你可以去搜索一下这个错误提示，看是原因，或者直接下载编译好的ntp软件rpm包来安装，相对来说更简单。

1.请确确认各节点的ntp包已经安装 ,我这里是个4.2.2的版本

[oracle@nascds10 ~]$ rpm -qa | grep ntp

ntp-4.2.2p1-9.el5_4.1

2.请编辑各个节点的ntp.conf文件

[oracle@nascds10 ~]$ su - root

Password:

[root@nascds10 ~]# vi /etc/ntp.conf

#New ntp server added by Robinson

server 192.168.1.128 prefer <<<<===========这里是时钟服务器

restrict 192.168.7.0 mask 255.255.255.255 nomodify notrap #基于网段的限制（限制在网段192.168.7.0）

broadcastdelay 0.008

[root@nascds11 ~]# vi /etc/ntp.conf

#New ntp server added by Robinson

server 192.168.7.71 prefer

broadcastdelay 0.008

3、配置ntpd的参数，我们主要强调的是要配置成"微调的模式" 也就是在options中要加入 -x的选项

[root@nascds10 ~]# vi /etc/sysconfig/ntpd

#The following item added by Robinson

#Set to 'yes' to sycn hw clock after successful ntpdate

SYNC_HWCLOCK=yes

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

[root@nascds11 ~]# vi /etc/sysconfig/ntpd

The following item added by Robinson

SYNC_HWCLOCK=yes

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

4、自动启动配置

[root@nascds10 ~]# chkconfig ntpd on

[root@nascds11 ~]# chkconfig ntpd on

5、重启一下，使最新配置生效

[root@nascds10 ~]# service ntpd restart

Shutting down ntpd: [ OK ]

ntpd: Synchronizing with time server: [ OK ]

Syncing hardware clock to system time [ OK ]

Starting ntpd: [ OK ]

[root@nascds11 ~]# service ntpd restart

Shutting down ntpd: [ OK ]

ntpd: Synchronizing with time server: [ OK ]

Syncing hardware clock to system time [ OK ]

Starting ntpd: [ OK ]

6、检查ntpd进程的状态

[root@nascds10 ~]# ntpq -p

remote refid st t when poll reach delay offset jitter

LOCAL(0).LOCL. 10 l 40 6410.0000.000 0.001

[root@nascds11 ~]# ntpq -p
