Linux系统配置yum源和ntpd服务

一.配置yum源：

1.Centos7系统：

执行vi /etc/yum.repos.d/CentOS-Base.repo，将原有内容替换为如下内容：

[base]name=CentOS-$releasever - Base - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-7

[updates]name=CentOS-$releasever - Updates - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/updates/$basearch/gpgcheck=1gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-7

[extras]name=CentOS-$releasever - Extras - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/extras/$basearch/gpgcheck=1gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-7

[centosplus]name=CentOS-$releasever - Plus - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-

[contrib]name=CentOS-$releasever - Contrib - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/contrib/$basearch/gpgcheck=1enabled=0gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-7

wq保存文件退出。

2.Centos6系统：

执行vi /etc/yum.repos.d/CentOS-6.repo，将原有内容替换为如下内容：

[base]name=CentOS-$releasever - Base - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-6

[updates]name=CentOS-$releasever - Updates - mirrors.jdcloudcs.combaseurl=http://mirrors.jdcloudcs.com/centos/$releasever/updates/$basearch/gpgcheck=1gpgkey=http://mirrors.jdcloudcs.com/centos/RPM-GPG-KEY-CentOS-6

wq保存文件退出。

3.Ubantu系统：

执行vi /etc/apt/sources.list，将原有内容替换为如下内容：

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial main restricted

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial-updates main restricted

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial universe

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial-updates universe

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial-security universe

deb http://mirrors.jdcloudcs.com/ubuntu/ xenial-security multiverse

wq保存文件退出。

二.配置ntpd服务：

1.调整ntpd配置文件：

执行vi /etc/ntp.conf，将原有内容替换为如下内容：

driftfile /var/lib/ntp/drift

pidfile /var/run/ntpd.pid

logfile /var/log/ntp.log

#Access Control Support

restrict default kod nomodify notrap nopeer noquery

restrict -6 default kod nomodify notrap nopeer noquery

restrict 127.0.0.1

#local clock

server 127.127.1.0

fudge 127.127.1.0 stratum 10

#jdcloud ntp server

server ntp.jdcloudcs.com iburst minpoll 4 maxpoll 10

fudge ntp.jdcloudcs.com stratum 2

wq保存文件退出。

2.启动ntpd服务：

执行services ntpd start（Centos6系统）

执行systemctl start ntpd（Centos7系统）

执行services ntpd start（Ubantu系统）

3.设置开机自启动服务：

执行chkconfig ntpd on（Centos6系统）

执行systemctl enable ntpd（Centos7系统）

执行chkconfig ntpd on（Ubantu系统，需要先apt-get install chkconfig进行安装）
