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

$ 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。
# 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
