对于新装 CentOS 系统,我个人会通常做以下工作
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
