Solarisメモ

Last updated at Posted at 2013-08-05

sudoの代わりはpfexec

  • 現場ではsu -してましたが、pfexecコマンドあるんですよ。

ネットワーク設定

  • hostname.インターフェース名 というファイルにIPアドレスを記入する。
$ ls -l /etc/hosts
lrwxrwxrwx 1 root root 12 2009-11-08 19:25 /etc/hosts -> ./inet/hosts

$ cat /etc/hostname.bge0 
192.168.10.191

$ cat /etc/netmasks
192.168.10.0    255.255.255.0

$ cat /etc/defaultrouter
192.168.10.1

smb.confの場所

  • /etc/sfw/smb.conf
$ pfexec svcadm restart svc:/network/samba:default

disk

fstabではなくvfstab

$ cat /etc/vfstab 
#device         device          mount           FS      fsck    mount   mount

ソフトウェアRAID

現場ではハードウェアRAIDでした。ハードウェアRAIDの状態は/var/adm/messagesで確認だったか
raidの同期状態がわかります。zpoolについてはこちら

$ zpool status
  pool: rpool
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        rpool       ONLINE       0     0     0
          mirror    ONLINE       0     0     0
            c8d0s0  ONLINE       0     0     0
            c9d0s0  ONLINE       0     0     0

ディスクの状態

$ zfs list

rpool                       646G   267G   448G  /rpool

rpool/dump                 1023M   267G  1023M  -
rpool/export               16.6G   267G    21K  /export
rpool/export/home          16.6G   267G  16.4G  /export/home

rpool/swap                 1023M   268G   448M  -

homeディレクトリがnfsを想定して用意されているかな？

  • /rpool/export/home/{ユーザー名}/

diskのクローン・・・

  • Linuxの1CDからddしたらいいよ。RAIDドライバの関係でHDDを認識しづらいのでRedHadのCDがオススメ。

アプリケーションディレクトリが綺麗

  • /usr/gnu/bin
  • /usr/bin
  • /usr/X11/bin
  • /usr/sbin
  • /sbin
  • /usr/php/bin/
  • /usr/mysql/bin/
  • /usr/apache2/2.2/bin/
