gentoo 时间不准确问题解决方法

狐狸贝贝 — Wed, 25 Feb 2009 07:35:00 GMT

我用的亚洲上海的时间：
Code:
#ln -sf /usr/share/zoneinfo/Asia/Harbin /etc/localtime
当前有了两个时间：一个是系统启动时候的时间，就是主板上的硬件时间一个是当前系统时间。系统以启动时的系统时间安作为UTC－格林威治标准时间为标准再根据当前时区增加或减少了时差得到的结果。所以是不准确的。
先读取主板上的硬件时间：
Code:
#hwclock --show
用这个时间同步系统时间：
#hwclock --hctosys
编辑系统时间为本地时间而不是UTC时间：
Code:
#nano -w /etc/conf.d/clock
就是把这一句：
CLOCK="UTC" 改成CLOCK="local"
重启系统，重新设置时间，并把系统时间同步回硬件时间
Code:
#date 095502132009
#hwclock --systohc

中间牵扯到系统的UTC和local的变更问题，逻辑关系挺麻烦。做个笔记吧，至少解决了。

gentoo下安装JBoss Web Server 2.1.2

狐狸贝贝 — Wed, 18 Feb 2009 07:11:00 GMT

1、安装jdk并配置环境
# emerge sun-jdk
# nano /etc/env.d/20java-config
添加以下内容

PATH="/opt/sun-jdk-1.6.0.12/bin"
ROOTPATH="/opt/sun-jdk-1.6.0.12/bin"
CLASSPATH=.:/opt/sun-jdk-1.6.0.12/lib/dt.jar:/opt/sun-jdk-1.6.0.12/lib/tools.jar

2、安装jboss并配置环境
进入　http://www.jboss.org/jbossweb/downloads/jboss-web/

下载 JBoss Web Server 2.1.2.GA bintar，文件为jboss-web-2.1.2.GA.tar.gz
# tar -xvf jboss-web-2.1.2.GA.tar.gz

# mv jboss-web-2.1.2.GA /jboss

# nano /etc/env.d/99jboss-config
添加以下内容：

JBOSS_HOME="/jboss"
PATH="/jboss/bin"
ROOTPATH="/jboss/bin"

# /jboss/bin/startup.sh

Using CATALINA_BASE:   /jboss
Using CATALINA_HOME:   /jboss
Using CATALINA_TMPDIR: /jboss/temp
Using JRE_HOME:       /usr

3、浏览器里输入http://localhost:8080，显示以下页面说明正常

4、将JBOSS设置为开机自动运行
# nano /etc/conf.d/local.start
添加以下内容：

/jboss/bin/startup.sh

安装gentoo-bashcomp

狐狸贝贝 — Wed, 07 Jan 2009 08:32:00 GMT

安装gentoo-bashcomp的目的：
　　给portage相关命令（如emerge、equery、revdep-rebuile等）加上TAB补全功能

#emerge gentoo-bashcomp //顺带会装上app-shells/bash-completion

#nano /etc/profile //添加以下配置启用completion

[[ -f /etc/profile.d/bash-completion ]] && source /etc/profile.d/bash-completion

#env-update && source /etc/profile    //刷新env

#bashcomp-config enable gentoo        //启用gentoo-bashcomp

补充：
#bashcomp-config list        //列出需要手工启用bash-completion的命令列表
#bashcomp-config enable unrar    //启用rar的bash-completion

Gentoo 升级系统的标准步骤

狐狸贝贝 — Wed, 07 Jan 2009 07:09:00 GMT

Gentoo 升级系统的标准步骤

#emerge --sync      //升级整个portage目录
#emerge portage     //如果不是最新的portage，需要按提示执行此操作
#emerge python     //如果不是最新的python，需要按提示执行此操作
#/usr/sbin/update-python     //执行完emerge python后执行此操作

#emerge -avuDN world      //按照 /var/lib/portage/world 文件下的包，重新构建整个系统
参数说明：  --ask (-a) 控制Portage显示它要更新的软件包列表，并让您决定是否继续更新
                --verbose (-v) 在屏幕上输出完整的文件列表
                --update (-u) 更新包的最佳版本
                --deep (-D) 更新系统中的每个软件包
                --newuse (-N) USE标记变更后，要使Portage检查USE标记的变动是否导致
                            需要安装新的软件包或者将现有的包重新编译

#emerge -av --depclean //清除不需要（孤立）的软件包

#revdep-rebuild //gentoolkit包里面的一个软件，用来检查系统的依赖关系是否都满足，
自动安装没有满足关系的包

#dispatch-conf //更新系统的配置文件

#emerge -e world //本地重新编译整个系统，USE标记变化不大时不需执行
参数说明： --emptytree (-e)
