Linux 应用

OS: Redhat Enterprise Linux AS 4

1. 配置IP地址

-- first approach
# setup  -- 打开服务列表 -> Network Configuration -> 即可打开配置IP地址的图形界面, 即可进行配置.

-- second approach
# ifconfig eth0 {IP} {Mask}

-- third approach
# vi /etc/sysconfig/network-scripts/ifcfg-eth0 -- 修改里面的IP值即可

-- 修改IP后需要重启network
# service network stop
# service network start

-- 可以用ifconfig 查看IP地址
# ifconfig

-- 域名解析地址
# vi /etc/resolv.conf --修改DNS解析地址，可以添加过个nameserver=IP address

-- 测试网络连接
# ping IP

-- 测试是否能访问外网
# wget www.baidu.com

--------------------------------------------------------

-- 为同一块网卡配置多个IP地址
# cd /etc/sysconfig/network-scripts
# cp ifcfg-eth0 ifcfg-eth0:0
# vi ifcfg-eth0:0 -- 修改里面的配置， 重启network 即可

2. 安装JDK 6.0

/*
下载 jdk1.6.0_17 
url = [url]http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jdk-6u17-linux-i586.bin?BundledLineItemUUID=cdxIBe.oCXYAAAEl5xgxdJeo&OrderID=XCZIBe.owMwAAAEl3RgxdJeo&ProductID=lBFIBe.oSOMAAAEkGehn5G0y&FileName=/jdk-6u17-linux-i586.bin[/url]
*/
# wget {url}
# mkdir jdk
# mv {jdk file name} jdk/jdk-6u17-linux-i586.bin
# cd jdk
# chmod +x jdk-6u17-linux-i586.bin
# ./jdk-6u17-linux-i586.bin
-- accept license, enter yes
# rpm -ivh [.rpm]

-- configure the enviroment variable
# vi /etc/profile

/* 在 export ... 前面增加
    JAVA_HOME=/usr/java/jdk1.6.0_17
    ClASSPATH=$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/tools.jar
    PATH=$JAVA_HOME/bin:$PATH
    EXPORT JAVA_HOME CLASSPATH
*/

3. 安装Artifactory

--下载软件
# unzip artifactory-2.1.2.zip
# /artifactory-2.1.2/bin/artifactory.sh & -- 启动artifactory

3. 加载cdrom

# cd /mnt
# mkdir cdrom
# monut /dev/cdrom /mnt/cdrom -- 加载光驱内容
# umount /mnt/cdrom -- 退出光驱
# eject -- 弹出光驱

4. Commands

$ su -root -- 切换到root用户， 有一次我启动linux后用一个普通用户进入登陆系统，结果进去后不能用ifconfig命令，也上不了外网。后来我就用这个命令su -root 而不是仅仅是su 以root的用户登陆系统后，就可以用ifconfig命令了，也可以上外网了。

5. SVN command

# svn export --force 'http://ip[:port]/svn/repos' dest_directory -- 从SVN服务器上导出文件

# svn --help -- 可用命令

对于rpm软件包，其安装方法如下
　1、安装命令：　同第一种方式一样，将安装文件拷贝至你的目录中。然后使用rpm来安装该文件。命令如下：
　　       #rpm i filename.i386.rpm
　　rpm将自动将安装文件解包，并将软件安装到缺省的目录下。并将软件的安装信息注册到rpm的数据库中。参数i的作用是使rpm进入安装模式。

2、rpm常用参数
-i 安装软件
-t 测试安装，不是真的安装
-p 显示安装进度
-f 忽略任何错误
-U 升级安装
-v 检测套件是否正确安装

这些参数可以同时采用。更多的内容可以参考RPM的命令帮助。
四、软件的卸载
　　1. 软件的卸载主要是使用rpm来进行的。卸载软件首先要知道软件包在系统中注册的名称。

键入命令：
　   　     #rpm -q -a
　　即可查询到当前系统中安装的所有的软件包。
　　2. 确定了要卸载的软件的名称，就可以开始实际卸载该软件了。

键入命令：
　　        #rpm -e 软件名
　　即可卸载软件。参数e的作用是使rpm进入卸载模式。对名为[package name]的软件包进行卸载。

注意：1、系统中各个软件包之间相互有依赖关系。如果因存在依赖关系而不能卸载，rpm将给予提示并停止卸载。你可以使用如下的命令来忽略依赖关系，直接开始卸载：
　#rpm -e 软件名 -nodeps
忽略依赖关系的卸载可能会导致系统中其它的一些软件无法使用

　   2、后面使用的是软件名，而不是软件包名（package name）。例如，要安装software-1.2.3-1.i386.rpm这个包时，应执行：
   #rpm –ivh software-1.2.3-1.i386.rpm

而当卸载时，则应执行：
#rpm –e software

3、在Linux中还提供了象GnoRPM、kpackage等图形化的RPM工具，使得整个过程会更

加简单。
