[原创实践]redhat linux 5.3搭建Nexus

1：下载安装JDK，配置好环境变量（JAVA_HOME等）

下载linux下64位的jdk-7u45-linux-x64.tar.gz（百度网盘下载，官网的jdk-7u51-linux-x64.tar.gz总是下载失败），上传到/tmp目录下。

cd  /opt/app/jdk/64/

tar -zxvf  jdk-7u45-linux-x64.tar.gz -C /opt/app/jdk/64/

修改`/.bash_profile

export JAVA_HOME=/opt/app/jdk/64/jdk1.7.0_45
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

执行 source ~/.bash_profile

使配置文件立即生效。

验证安装成功可执行echo $JAVA_HOME

java -version

2：Maven安装。

（1）maven官网下载apache-maven-3.1.1-bin.tar.gz，上传到linux服务器的/opt/tmp目录下。

（2)建立/opt/app/maven目录

(3)安装maven,其实就是解压缩到目录
cd /tmp
tar -zxvf  apache-maven-3.1.1-bin.tar.gz -C /opt/app/maven/
hotel用户下配置环境变量，编辑.bash_profile文件，添加如下代码
export MAVEN_HOME=/opt/app/maven/apache-maven-3.1.1
export PATH=${PATH}:${MAVEN_HOME}/bin

执行
source ~/.bash_profile

使配置文件立即生效。

验证安装成功可执行mvn -version

3:nexus的安装

下载nexus-2.7.2-03-bundle.tar.gz

建立/opt/app/nexus目录
cd /tmp
tar -zxvf  nexus-2.7.2-03-bundle.tar.gz -C /opt/app/nexus/
cd /opt/app/nexus/nexus-2.7.2-03/bin/

执行./nexus  start，在日志文件中/opt/app/nexus/nexus-2.7.2-03/logs/wrapper.log发现错误

root用户下

/etc/selinux/config SELINUX=enforcing 改成 SELINUX=disabled

hotel用户执行

chcon -t texrel_shlib_t /opt/app/nexus/nexus-2.7.2-03/bin/jsw/lib/libwrapper-linux-x86-32.so

./nexus  start

验证启动是否成功：

lsof -i:8081
