mkdir /usr/local/java

cd /usr/local/java

rz -e jdk-8u211-linux-x64.tar.gz

tar -xvf   jdk-8u211-linux-x64.tar.gz

检查效果：

git 安装注册：

mkdir /usr/local/git

cd /usr/local/git

安装编译依赖：

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

下载Git并解压

wget https://github.com/git/git/archive/v2.3.0.zip

unizp  v2.3.0.zip

cd  v2.3.0.zip

指定编译安装路径和执行安装：

make prefix=/usr/local/git all && make prefix=/usr/local/git install

检查：

git --version

which git

whereis git

git注册，密钥生成：

maven 安装：

cd /usr/local

mkdir maven

cd /usr/local/maven

wget https://archive.apache.org/dist/maven/maven-3/3.1.0/binaries/apache-maven-3.1.0-bin.tar.gz

tar -zxvf apache-maven-3.1.0-bin.tar.gz

vim /etc/profile.d/maven.sh

#添加如下：

export MAVEN_HOME=/usr/local/maven/apache-maven-3.1.0
export PATH=${MAVEN_HOME}/bin:${PATH}

source /etc/profile.d/maven.sh

检验：

mvn -v

成功

本地仓库建立配置

mkdir /usr/local/maven

cd /usr/local/maven

rz -e apache-maven-3.6.1-bin.tar.gz

tar -xvf  apache-maven-3.6.1-bin.tar.gz

建立本地仓库

mkdir mvn-repo ：

cd   /usr/local/maven/apache-maven-3.6.1/conf

vi setting.xml

找到如下部分：

<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->

在此位置新增仓库刚才的mvn-repo路径：
<localRepository> /usr/local/maven/apache-maven-3.6.1/mvn-repo</localRepository>

代理设置：

找到<proxies>标签在里面修改host,port,：

<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username></username>
<password></password>
<host>proxy.we.com</host>
<port>8484</port>
<nonProxyHosts></nonProxyHosts>
</proxy>

镜像设置：

找到<miorrors>标签在里面加入ali镜像

<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>

四。环境变量配置java git ,maven

vi /ect/profile

#java_home
export JAVA_HOME=/usr/local/java/jdk1.8.0_211
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
#git 
export PATH="/usr/local/git/bin:$PATH"
#maven
#maven
export MAVEN_HOME=/usr/local/maven/apache-maven-3.6.1
export PATH=${MAVEN_HOME}/bin:${PATH}

保存后激活：

source /etc/profile
