关于安装linux时要怎么分区的考虑的參考方式?

对于使用最小化安装的centos7文件夹列表,注意链接方式的文件夹会在统计占用空间时不会算入的;

看看占用空间(链接文件夹不会出现)

ok到这里,是否你知道每个大概多少足够了?

这里再看眼使用了几年的普通线上webserver的文件夹(ubuntu的)

看看占用空间情况(有mysql,nginx,php)

86M     ./boot
328G    ./var
4.0K    ./dev
0       ./sys
330G    .

再看看var中的占用情况(mysql 的data是放在lib中,www是站点与一些相关备份)

var/www就没有什么好多说了.自己决定的

ok.到这里是不是就能够知道怎么分了呢.

用得足够久.或是看看别人同样的作用server.这里就非常easy知道怎么分了.
