Linux环境编写脚本安装配置JDK,Tomcat，含Tomcat自启动

mkdir /usr/java







mkdir /znywImage















cp -f /usr/jdk-7u79-linux-x64.tar.gz /usr/java















tomcatPath=/usr/apache-tomcat-8.5.20







if [  -d "$tomcatPath" ]; then







    echo "删除$tomcatPath目录"







    sudo rm -rf $tomcatPath







    echo "目录$tomcatPath删除成功"







fi















jdkPath=/usr/java/jdk1.7.0_79







if [  -d "$jdkPath" ]; then







    echo "删除$jdkPath目录"







    sudo rm -rf $jdkPath







    echo "目录$jdkPath删除成功"







fi















tar -xzvf /usr/apache-tomcat-8.5.20.tar.gz -C /usr







tar -xzvf /usr/java/jdk-7u79-linux-x64.tar.gz -C /usr/java

echo "原来文件的总行数"







awk 'END{print NR}' $myfile















echo "jdk开始的行数"







grep -an "export JAVA_HOME=/usr/java/" $myfile |cut -d: -f1
