对于使用最小化安装的centos7目录列表,注意链接方式的目录会在统计占用空间时不会算入的;
看看占用空间(链接目录不会出现)
ok到这里,是否你知道每一个大概多少足够了?
这里再看眼使用了几年的普通线上web服务器的目录(ubuntu的)
看看占用空间情况(有mysql,nginx,)
du -h -d 1 796K ./run 9.4M ./etc 4.0K ./opt 1.2G ./usr 640M ./lib 4.0K ./media 4.0K ./cdrom 172K ./build 5.0M ./tmp 4.0K ./mnt 8.0K ./srv 4.0K ./lib64 9.8M ./bin 272K ./root du: cannot access ?./proc/2121/task/2121/fd/4?: No such file or directory du: cannot access ?./proc/2121/task/2121/fdinfo/4?: No such file or directory du: cannot access ?./proc/2121/fd/4?: No such file or directory du: cannot access ?./proc/2121/fdinfo/4?: No such file or directory du: cannot access ?./proc/23692/task/23692/fd/26?: No such file or directory du: cannot access ?./proc/23692/task/23692/fd/35?: No such file or directory du: cannot access ?./proc/23692/task/23692/fd/39?: No such file or directory 0 ./proc 11M ./sbin 16K ./lost+found 264K ./home 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是网站与一些相关备份)
ll total 72 drwxr-xr-x 15 root root 4096 Sep 23 02:50 ./ drwxr-xr-x 24 root root 4096 Sep 23 02:45 ../ drwxrwxrwx 3 root root 4096 Sep 25 06:33 backups/ drwxr-xr-x 11 root root 4096 Sep 24 19:04 cache/ drwxrwsrwt 2 root whoopsie 4096 Nov 14 06:25 crash/ drwxr-xr-x 47 root root 4096 Sep 24 19:02 lib/ drwxrwsr-x 2 root staff 4096 Jan 21 2011 local/ lrwxrwxrwx 1 root root 9 Sep 23 02:50 lock -> /run/lock/ drwxrwxr-x 15 root syslog 4096 Nov 19 06:47 log/ drwx------ 2 root root 16384 May 21 2011 lost+found/ drwxrwsr-x 2 root mail 4096 May 21 2011 mail/ drwxrwsrwt 2 root whoopsie 4096 Sep 23 02:44 metrics/ drwxr-xr-x 2 root root 4096 May 21 2011 opt/ lrwxrwxrwx 1 root root 4 Sep 23 02:50 run -> /run/ drwxr-xr-x 5 root root 4096 Sep 23 04:01 spool/ drwxrwxrwt 2 root root 4096 Sep 23 03:04 tmp/ drwxr-xr-x 12 root root 4096 Nov 13 10:30 www/

var/www就没有什么好多说了.自己决定的
看看除了mysql外,其它东西占用多

再看眼没用上的阿里去的

ok.到这里是不是就可以知道怎么分了呢.
用得足够久.或是看看别人相同的作用服务器.这里就很容易知道怎么分了.
