一：JDK

1.Installation

Download the lasted version of the JDK from: http://java. ,now is JDK1.7.0_10.
Unpack the arcive to /usr/lib/jvm/java with the below command line:

tar -zxvf jdk-7u10-linux-i586.tar.gz

2. Set java environment variable

# vi /etc/profile

# This is added by selina for set java environment:

JAVA_HOME=/usr/lib/jvm/java/jdk1.7.0_10

JRE_HOME=/usr/lib/jvm/java/jdk1.7.0_10/jre

export JAVA_HOME

export JRE_HOME

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

# end of set java environmnet

save and exit.

# source /etc/profile //with immediate effect

# java -version or echo $JAVA_HOME

check whether take effect :logout then

# java -version or echo $JAVA_HOME

二：Maven

1.Installation

Download the lasted version of the Maven from http://maven./download.html ,now is 3.0.4 .
Unapack the archive to /usr/local with beow the command line :
tar -zxvf apache-maven-3.0.4-bin.tar.gz
rename apache-maven-3.0.4 as maven3
mv apache-maven-3.0.4 maven3

2.Set Maven environment variable

# vi /etc/profile

# This is added by selina for set Maven environment:

MAVEN_HOME=/usr/local/maven3

export MAVEN_HOME

export PATH=$MAVEN_HOME/bin:$PATH

# end of set java environmnet

save and exit.

# source /etc/profile //with immediate effect

# mvn -v or echo $MAVEN_HOME

check whether take effect :logout then

# mvn -v or echo $MAVEN_HOME

Note that if you use "mvn -v" to see ,will show maven and jave version info indicate that successfully installed and configured.

三：Nexus

1.Installation

Download the lasted version of the Nexus from http://nexus./downloads/ ,now is nexus-2.2-01.

Unpack the archive to /usr/local with the below command line

tar -zxvf nexus-2.2-01-bundle.tar.gz

and remane to nexus2 with the below command line

mv nexus-2.2-01-bundle nexus2

2. Run Nexus

$ cd /usr/local/nexus2/bin/jsw/linux-x86-32

$ ./nexus start (restart/stop...) # use ordinary account not root

if successd ,Go to browser http://ip:8081/nexus ,account and passowd is admin and admin123

(if you want to change port number ,pls go to ./nexus2/conf/nexus.properties to set ,the default is 8081)

issues:

(1)if successfully installed ,will show :

Starting Nexus OSS...

Stared Nexus OSS

But ,after installing nexus ,excute command "./nexus start" failed ,show the below message:

Starting Nexus OSS...

Failed to start Nexus OSS.

Solution : this is casued by priviledge of nexus directory ,it belongs to root user .After change the owner of the nexus directory to the current user ,rerun the command "./nexus start",it works.

sudo chown -R selina:selina ../../nexus

(2)Can't browser

when http://ip:8081/nexus ,failed ,need to see log message from: ./nexus/logs/wrapper.log ,show "Unable to start JVM: No such file or directory" in here ,

Solution : editing "<nexus_root>/bin/jsw/conf/wrapper.conf" and changing "wrapper.java.commad" the full path to my java executable

wrapper.java.commad={JAVA_HOME}/bin/java

Again to http://ip:8081/nexus ,failed ,see log message ,show " error..Temp directory:/usr/lcoal/sonatype-work/nexus/tmp "

Solution : chmod -R 777 /usr/local/sonatype-work/nexus/tmp

Congratulations ,well done.Click the "Login In" on the top right corner.the default username is admin ,password is admin123.

登录后最重要的事情就是打开远程索引下载，操作为选择菜单Administrator->Repositories，然后在右边打开的列表中依次选择type字段为proxy的记录，在下方的编辑区中修改"Download Remote Indexes"值为true，再从这三个仓库上点右键选择"Reapir Index"，这一步别忘，Repair Index后，Nexus会从后台去官方地址下载仓库索引文件，大概20M大小，根据网速快慢下载相应时间后选择仓库时会以树形目录的方式显示仓库内容。(注意：如果repaire-index后,在“browser index"里仍然看不到东西，要确定/usr/lcoal/sonatype-work/nexus目录是否有写权限 ）Central的"Remote storage location"默认的是http://repo1./maven2,因这是国外网站，忒慢，如此找到了以下这个源镜像：http://repo.maven./maven2想要maven使用刚刚配置的nexus服务作为仓库服务器需要修改settings.xml文件。

在maven中存在两个 settings.xml，一个位于maven2的安装目录conf下面，作为全局性配置。对于团队设置，保持一致的定义是关键，所以 maven/conf下面的settings.xml就作为团队共同的配置文件。保证所有的团队成员都拥有相同的配置。当然对于每个成员，都需要特殊的自定义设置，如用户信息，所以另外一个settings.xml就作为本地配置。默认的位置为：${HOME} /.m2/settings.xml目录

然后，在从你的工程里的pom.xml中加入以下内容：

<repository>

  <name>Nexus Release Repo</name>
  <url>http://localhost:8081/nexus/content/repositories/releases</url>
</repository>

  <id>snapshots</id>
  <name>snapshots</name>
  <url>http://localhost:8081/nexus/content/repositories/snapshots</url>
