扩容

系统盘只有2G，需要扩下

虚拟机虚拟介质扩容量

先在virtualbox中对系统盘扩容到10G

linux系统内部扩容

1、下载parted命令
2、扩容
参考https://blog.csdn.net/qq_45664055/article/details/137920769
parted输入后使用resizepart 命令进行扩
3、调整文件系统
ext4的使用resize2fs

resize2fs /dev/sda1

4、使用df -h命令查看发现已经扩容OK了

设置时区

root用户下执行

timedatectl set-timezone 'Asia/Shanghai'

编辑颜色

编辑~/.bashrc
放开以下几行的注释后重新登录即可。

 export LS_OPTIONS='--color=auto'
 eval "$(dircolors)"
 alias ls='ls $LS_OPTIONS'
 alias ll='ls $LS_OPTIONS -l'
