linux下自動化部署jdk和tomcat

1.將jdk與tomcat安裝包與腳本放在同一目錄下

2.使用vim 打開腳本文件在命令格式下將腳本轉成unix格式：set fileformat=unix

3.使用 chmod +x 腳本名.sh  將腳本文件變成可執行文件

4.使用source命令執行腳本 source ./腳本名.sh 

注意：該腳本會刪除舊的jdk 與 tomcat，若是之前的系統須要保留，請備份後執行

if [ -e /usr/local/java ];then
        echo "delete old exist jdk ..."
        sleep 2
        rm -rf /usr/local/java
        echo "install new jdk ..."
        mkdir /usr/local/java
        sleep 2
        tar zxvf jdk* -C /usr/local/java
else
        mkdir /usr/local/java
        tar zxvf jdk* -C /usr/local/java
fi

JDKPATH=`ls /usr/local/java`
echo ${JDKPATH}

echo " ">>/etc/profile
echo "# JDK ENV">>/etc/profile
echo "JAVA_HOME=/usr/local/java/${JDKPATH}">>/etc/profile
echo 'export JAVA_HOME=$JAVA_HOME'>>/etc/profile
echo 'export PATH=$PATH:$JAVA_HOME/bin'>>/etc/profile
if [ -e /usr/local/tomcat ];then
    echo "delete old exist tomcat ..."
    sleep 2
    rm -rf /usr/local/tomcat
    echo "install new tomcat ..."
    mkdir /usr/local/tomcat
    sleep 2
    tar zxvf apache-tomcat* -C /usr/local/tomcat/
else
    mkdir /usr/local/tomcat
    tar zxvf apache-tomcat* -C /usr/local/tomcat/
fi

echo ""
echo "source /etc/profile"
    source /etc/profile
