IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=f72ecf66-d8b0-456b-9e61-05297b1d4131
DEVICE=ens33
ONBOOT=yes # 开机启动
IPADDR=192.168.9.100 # 设置本机IP
GATEWAY=192.168.9.2 # 设置本机的网关
NETMASK=255.255.255.0 # 设置本机的掩码

#  设置DNS
cat /etc/resolv.conf                          
nameserver 223.5.5.5
nameserver 114.114.114.114

# 重启网络服务

2. 更换源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum clean all && yum makecache

3. 安装常用工具

curl -sSL https://gitee.com/sgfoot/library/raw/master/oh-my-zsh/install.sh |bash

yum install net-tools git vim telnet screen tree nmap dos2unix lrzsz nc lsof wget tcpdump htop iftop iotop sysstat nethogs traceroute -y

yum install -y epel-release

4. 时间同步

# 安装
yum install chrony -y

# 管理
systemctl start chronyd      #启动
systemctl status chronyd    #查看
systemctl restart chronyd   #重启
systemctl stop chronyd      #停止

systemctl enable chronyd     #设置开机启动

timedatectl set-timezone Asia/Shanghai

设置时间源

vim /etc/chrony.conf

# 注释默认的同步地址
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ntp1.aliyun.com iburst # 添加这一行,表示与本机同步时间,其它机器都填写这个地址。
server ntp2.aliyun.com iburst
server ntp.ntsc.ac.cn iburst 

# Allow NTP client access from local network.
# allow 192.168.9.0/24   #允许哪些服务器到这台服务器来同步时间

systemctl restart chronyd   #重启

查看时间&同步


# 设置完时区后,强制同步下系统时钟:
chronyc -a makestep

# 校准时间服务器
chronyc tracking

# 查看
timedatectl

# 命令行模式查看时间同步源   
chronyc sources -v

# 查看时间同步源状态: 
chronyc sourcestats -v

5. 共享目录

yum install -y open-vm-tools

vmhgfs-fuse /mnt/hgfs/
