Chrony介绍和安装

1.Chrony（时间同步服务）

1.1 Chrony介绍

Chrony 是一个用于时间同步的软件，它旨在提供高精度的系统时钟同步。Chrony 软件包括一个 NTP（Network Time Protocol，网络时间协议）服务器和客户端，可以帮助计算机系统与网络时间服务器同步，以确保系统时钟的准确性。

以下是 Chrony 的一些关键特点和功能：

高精度时钟同步：Chrony 旨在提供比传统的 NTP 实现更高精度的时钟同步。它采用一些先进的算法和技术，例如平滑过渡和时钟漂移补偿，以确保系统时钟能够尽可能准确地与参考时间源同步。
网络时间协议支持：Chrony 支持 NTP 协议，可以与外部的 NTP 服务器进行通信，从而获取准确的时间信息。这使得计算机系统可以通过网络与可靠的时间源进行同步，以消除时钟漂移和误差。
灵活的配置选项：Chrony 提供了丰富的配置选项，允许管理员根据特定的需求和环境对时钟同步进行定制。管理员可以设置不同的 NTP 服务器、调整同步频率和优先级等参数。
容错和稳健性：Chrony 具有一定的容错机制，可以处理网络中断、临时不可用的时间服务器或其他异常情况。它可以自动调整同步策略，以确保系统时钟的稳定性和准确性。
系统时钟管理：除了作为 NTP 客户端，Chrony 还可以作为系统时钟管理工具，监视和调整系统时钟，以确保其精度和稳定性。

总之，Chrony 是一个功能强大的时间同步工具，适用于需要高精度时钟同步的计算机系统，尤其是对时间同步精度要求较高的服务器和网络设备。通过使用 Chrony，用户可以确保其系统时钟与外部时间源同步，从而提高计算机系统的时间准确性和稳定性。

1.2 Chrony 文件组成

包：chrony

两个主要程序：chronyd和chronyc

chronyd：后台运行的守护进程，用于调整内核中运行的系统时钟和时钟服务器同步。它确定计算机增减时间的比率，并对此进行补偿
chronyc：命令行用户工具，用于监控性能并进行多样化的配置。它可以在chronyd实例控制的计算机上工作，也可在一台不同的远程计算机上工作

服务unit 文件： /usr/lib/systemd/system/chronyd.service

监听端口：服务端: 123/udp,客户端: 323/udp

配置文件： /etc/chrony.conf

1.3 配置文件chrony.conf

server - 可用于时钟服务器，iburst 选项当服务器可达时，发送一个八个数据包而不是通常的一个数据包。 包间隔通常为2秒,可加快初始同步速度

driftfile - 根据实际时间计算出计算机增减时间的比率，将它记录到一个文件中，会在重启后为系统时钟作出补偿

rtcsync - 启用内核模式，系统时间每11分钟会拷贝到实时时钟（RTC）

allow / deny - 指定一台主机、子网，或者网络以允许或拒绝访问本服务器

cmdallow / cmddeny - 可以指定哪台主机可以通过chronyd使用控制命令

bindcmdaddress - 允许chronyd监听哪个接口来接收由chronyc执行的命令

makestep - 通常chronyd将根据需求通过减慢或加速时钟，使得系统逐步纠正所有时间偏差。在某些特定情况下，系统时钟可能会漂移过快，导致该调整过程消耗很长的时间来纠正系统时钟。该指令强制chronyd在调整期大于某个阀值时调整系统时钟

local stratum 10 - 即使server指令中时间服务器不可用，也允许将本地时间作为标准时间授时给其它客户端

2.Chrony安装

2.1 主机初始化

2.1.1 设置网卡名

Rocky Linux 9/10、Almalinux 9/10、CentOS Stream 9/10、AnolisOS 23、OpenCloudOS 9：
- 创建 systemd 链接文件：创建 /etc/systemd/network/70-eth0.link 文件。

[root@rocky10 ~]# mkdir -p /etc/systemd/network/
[root@rocky10 ~]# touch /etc/systemd/network/70-eth0.link

Rocky Linux 8、Almalinux 8、CentOS 7、CentOS Stream 8、openEuler 22.03和24.03 LTS、AnolisOS 8、OpenCloudOS 8、Kylin Server v10/v11、UOS Server v20：
- 修改 GRUB 配置文件：打开 /etc/default/grub 文件，添加以下内容到 GRUB_CMDLINE_LINUX 行

net.ifnames=0 biosdevname=0

执行以下命令：

sed -ri.bak '/^GRUB_CMDLINE_LINUX=/s@"$@ net.ifnames=0 biosdevname=0"@' /etc/default/grub

然后更新 GRUB 配置：

grub2-mkconfig -o /boot/grub2/grub.cfg

如果是 UEFI 引导系统，更新命令为：

# Rocky
grub2-mkconfig -o /boot/efi/EFI/rocky/grub.cfg

# Almalinux
grub2-mkconfig -o /boot/efi/EFI/almalinux/grub.cfg

# CentOS
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

# Kylin Server
grub2-mkconfig -o /boot/efi/EFI/kylin/grub.cfg

# UOS Server
grub2-mkconfig -o /boot/efi/EFI/uos/grub.cfg

# UEFI 引导系统可以直接执行下面命令：
EFI_DIR=`find /boot/efi/ -name "grub.cfg" | awk -F"/" '{print $5}'`
grub2-mkconfig -o /boot/efi/EFI/${EFI_DIR}/grub.cfg

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="<网卡MAC地址>", NAME="eth0"

注意：创建Udev这个步骤只在AnolisOS 8上执行。

将 <网卡MAC地址> 替换为实际网卡的 MAC 地址。

net.ifnames=0 biosdevname=0

执行以下命令：

sed -ri.bak '/^GRUB_CMDLINE_LINUX=/s@"$@net.ifnames=0 biosdevname=0"@' /etc/default/grub

然后更新 GRUB 配置：

grub-mkconfig -o /boot/grub/grub.cfg

如果是 UEFI 引导系统，更新命令为：

# Ubuntu
grub-mkconfig -o /boot/efi/EFI/ubuntu/grub.cfg

# Debian
grub-mkconfig -o /boot/efi/EFI/debian/grub.cfg

# UEFI 引导系统可以直接执行下面命令：
