chronyc命令

【chronyc】是一个用于同步计算机时间的工具，它可以确保计算机时间与网络时间服务器保持一致，通过使用chronyc,我们可以避免因为计算机时间不准确而导致的各种问题，如计划任务失败、系统性能下降等，本文将介绍chronyc的基本使用方法和一些常见的配置选项。,我们需要安装chronyc，在大多数Linux发行版中，可以使用包管理器进行安装，在Ubuntu系统中，可以使用以下命令安装chronyc:, ,安装完成后，我们可以使用chronyc命令来查看当前的时间同步状态，要查看本地时间与服务器时间的差异，可以使用以下命令：,接下来，我们可以使用chronyc命令来进行时间同步，需要选择一个合适的时间服务器，在国内，我们可以使用NTP(Network Time Protocol)服务器，以下是一些常用的NTP服务器：,– ntp.aliyun.com,– ntp1.aliyun.com,– ntp2.aliyun.com,– ntp3.aliyun.com,– ntp4.aliyun.com,– ntp5.aliyun.com,– ntp6.aliyun.com, ,– ntp7.aliyun.com,– ntp8.aliyun.com,– ntp9.aliyun.com,– ntp10.aliyun.com,– ntp11.aliyun.com,– ntp12.aliyun.com,– ntp13.aliyun.com,– ntp14.aliyun.com,– ntp15.aliyun.com, ,要将chronyc配置为使用指定的NTP服务器，可以使用以下命令：,your_server_ip是你要使用的NTP服务器的IP地址，配置完成后，chronyc会自动开始与指定的NTP服务器进行时间同步，我们可以使用以下命令查看同步进度：,chronyc还支持多种时间源，如GPS、PTP等，要启用这些时间源，可以使用以下命令：,your_source_name是你要在chronyc中添加的时间源名称，your_source_ip是该时间源的IP地址，your_options是你要传递给该时间源的选项，要启用GPS时间源，可以使用以下命令：,“`bash,sudo chronyc sources my_gps tracking 192.168.1.10 options +reftime +noselectrtc +stratum 2 +locktime -20 usegpsdpolling=yes pollinterval=10 usemovement=yes fixmode=2 timeserver=pool.ntp.org stratum=2 maxerror=10 minpoll=4 maxpoll=50 offset=0 delay=0 jitter=0 pathloss=inf repeater=30 reachability=25 direct=no publicize=no mtu=1492 weight=1 prefilter=no strictprefetch=no nomodify = yes forcedquery = yes queryport = 37 port = 123 key = “” logfile = “/var/
