關於安裝linux時要怎麼分區的考慮的參考方式?

標籤：linux   分區   掛載點   安裝   

對於使用迷你安裝的centos7目錄列表,注意連結方式的目錄會在統計佔用空間時不會算入的;

看看佔用空間(連結目錄不會出現)

ok到這裡,是否你知道每一個大概多少足夠了?

這裡再看眼使用了幾年的普通線上web伺服器的目錄(ubuntu的)

看看佔用空間情況(有mysql,nginx,php)

du -h -d 1796K    ./run9.4M    ./etc4.0K    ./opt1.2G    ./usr640M    ./lib4.0K    ./media4.0K    ./cdrom172K    ./build5.0M    ./tmp4.0K    ./mnt8.0K    ./srv4.0K    ./lib649.8M    ./bin272K    ./rootdu: cannot access â./proc/2121/task/2121/fd/4â: No such file or directorydu: cannot access â./proc/2121/task/2121/fdinfo/4â: No such file or directorydu: cannot access â./proc/2121/fd/4â: No such file or directorydu: cannot access â./proc/2121/fdinfo/4â: No such file or directorydu: cannot access â./proc/23692/task/23692/fd/26â: No such file or directorydu: cannot access â./proc/23692/task/23692/fd/35â: No such file or directorydu: cannot access â./proc/23692/task/23692/fd/39â: No such file or directory0       ./proc11M     ./sbin16K     ./lost+found264K    ./home86M     ./boot328G    ./var4.0K    ./dev0       ./sys330G    .

再看看var中的佔用情況(mysql 的data是放在lib中,www是網站與一些相關備份)

lltotal 72drwxr-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/

佔用空間

/var# du -h -d 116G     ./lib9.9G    ./log41G     ./backups4.0K    ./opt4.0K    ./local36K     ./spool16K     ./lost+found4.0K    ./mail17M     ./crash639M    ./cache4.0K    ./metrics262G    ./www4.0K    ./tmp328G    .

var/www就沒有什麼好多說了.自己決定的

看看除了mysql外,其它東西佔用多

/var# du -h -d 1 /var/lib/12M     /var/lib/php54.0K    /var/lib/misc15G     /var/lib/mysql8.0K    /var/lib/update-manager8.0K    /var/lib/sudo8.0K    /var/lib/ureadahead496K    /var/lib/usbutils20K     /var/lib/update-notifier74M     /var/lib/mlocate12K     /var/lib/sgml-base12K     /var/lib/locales140K    /var/lib/ucf8.0K    /var/lib/vim4.0K    /var/lib/update-rc.d20K     /var/lib/initramfs-tools14M     /var/lib/aptitude52K     /var/lib/belocs4.0K    /var/lib/initscripts4.0K    /var/lib/dhcp4.0K    /var/lib/ubuntu-release-upgrader32K     /var/lib/apache24.0K    /var/lib/git8.0K    /var/lib/logrotate4.0K    /var/lib/landscape4.0K    /var/lib/os-prober4.0M    /var/lib/nginx12K     /var/lib/AccountsService24K     /var/lib/libxml-sax-perl12K     /var/lib/xml-core8.0K    /var/lib/dbus3.7M    /var/lib/apt-xapian-index4.0K    /var/lib/ntpdate8.0K    /var/lib/apparmor4.0K    /var/lib/python48K     /var/lib/nssdb32M     /var/lib/dpkg146M    /var/lib/apt8.0K    /var/lib/pycentral4.0K    /var/lib/plymouth4.0K    /var/lib/libuuid28K     /var/lib/polkit-128K     /var/lib/pam8.0K    /var/lib/urandom32K     /var/lib/systemd4.0K    /var/lib/insserv16G     /var/lib/

再看眼沒用上的阿里去的伺服器

ok.到這裡是不是就可以知道怎麼分了呢.

用得足夠久.或是看看別人相同的作用伺服器.這裡就很容易知道怎麼分了.
