gentoo emerge command

by

升級系統/世界

emerge -uDN system ( world )

升級完世界 把多餘的東西砍掉

emerge --depclean

檢查 library 一致?

revdep-rebuild

用vmware , frame buffer I/O很慢 , 要加 -q

安裝被keywords mark起來的ebuild

把 ebuild 名稱加到 /etc/portage/package.keywords 就可以了

在 /etc/make.conf 加 ACCEPT_KEYWORDS=”~amd64″

裝特定版本的 package

emerge =www-servers/apache-2.x.x

cd /
mount -t proc proc /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
cp -L /etc/resolv.conf /mnt/gentoo/etc/
chroot /mnt/gentoo /bin/bash
env-update && source /etc/profile

[gentoo] 排除舊的 lib 相容問題

by 
 * Messages for package sys-devel/libtool-2.2.6b:

 * Old versions of installed libraries were detected on your system.
 * In order to avoid breaking packages that depend on these old libs,
 * the libraries are not being removed.  You need to run revdep-rebuild
 * in order to remove these old dependencies.  If you do not have this
 * helper program, simply emerge the 'gentoolkit' package.
 *
 *   # revdep-rebuild --library libltdl.so.3
 *
 * Once you've finished running revdep-rebuild, it should be safe to
 * delete the old libraries.  Here is a copy & paste for the lazy:
 *   # rm '/usr/lib64/libltdl.so.3'

下了 revdep-rebuild –library libltdl.so.3 會

[monster] monster.tw 記錄 / memo / ubuntu / 裝 圖形介面 / GUI / gnome desktop / ip address / setting

by

昨天晚上去一位朋友公司幫忙用他們的 server , 回來就想要做幾件事:

1. 記錄一下自己的 server 某些重要檔案, 也可供其他人參考

2. 備份重要 file

3. 隨時準備好最新版的救援CD/Live CD/Live USB , 最新版的 Monster LAMP pack 也要燒好收著.

4. 準備一個 “萬用” 含各類 driver 的 linux kernel , 以供救援使用.

5. 搞懂 booting steps / GRUB setting

service / daemon 管理工具

sysv-rc-conf text based utility :

sudo apt-get install sysv-rc-conf

另一套 GUI

sudo apt-get install gnome-system-tools gdm

monster.tw 是裝這個 apt-get install rcconf

列出 runlevels 的 program : chkconfig

裝 圖形介面 / GUI / gnome desktop

sudo apt-get install ubuntu-desktop --no-install-recommends

啟動 desktop manager :

/etc/init.d/gdm start

stop x server / 關掉 x window: /etc/init.d/gdm stop

改 IP address

cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 172.30.0.42
        netmask 255.255.255.0
        network 172.30.0.0
        broadcast 172.30.0.255
        gateway 172.30.0.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 8.8.8.8
        dns-search monster.tw

重新啟動 networking
/etc/init.d/networking restart

若要使用 DHCP 的話

auto eth0
iface eth0 inet dhcp

加上 default route

gateway 1.2.3.4

或另一個 static route

up route add -net 1.2.3.0 netmask 255.255.255.0 gw 1.2.3.4

change host name:

改 /etc/hostname
改 /etc/hosts

若是用 vmware 之類的軟體導致 clone 出來的 ubuntu 網路 interface 跑掉, 可以砍掉 
/etc/udev/rules.d/70-persistent-net.rules
後 reboot , 就可以解決了.

裝 dev-php5/pecl-memcache 有點問題

9d15a8d72725c3ef7655c96adb685696

解決:

在 /etc/portage/package.keywords 加上

dev-php5/pecl-memcache

gentoo NFS

by

在 gentoo 要裝 NFS client 要裝

emerge -av net-fs/nfs-utils portmap

/etc/init.d/portmap start

EDIT: /etc/fstab 加一行
freenas.monster.tw:/mnt/data/public     /m1 nfs rw,addr=172.30.0.xx    0 0

有 showmount 可以看 NFS 有 export 那些 directory 出來
