Linux中JDK，Tomcat配置安装,mysql服务
1,查看Linux位数下载对应的jdk
getconf LONG_BIT
2.对文件近解压到指定的目录
tar -xzvf /opt/jdk-11.0.7_linux-x64_bin.tar.gz -C /usr/local/java/
3.配置环境变量
vim /etc/profile
在文件最后编辑
export JAVA_HOME=/usr/local/java/jdk-11.0.7（--解压后的bin一级的目录）
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH
让配置文件生效
source /etc/profile
4.查看版本
java -version
