CentOS新装系统的后续工作

1.换源

我一般换 中国科学技术大学镜像源 ，因为阿里源、华为源都放过我鸽子XDDD

2.基础环境

sudo yum install gcc gcc-c++ pcre openssh openssh-devel openssl openssl-devel libtools cmake autoconf tcl ntpdate -y

# 升级内核和所有软体
sudo yum update -y

3.同步时间服务器(server time.ustc.edu.cn)

[root@basic-platform ~]# cat /etc/ntp.conf | grep -v "^#" | grep -v "^$"
driftfile /var/lib/ntp/drift
restrict default nomodify notrap nopeer noquery
restrict 127.0.0.1
restrict ::1
server time.ustc.edu.cn
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor

[root@basic-platform ~]# systemctl start ntpdate.service
