1.如果显示 java： 未找到命令
source /etc/profile
2.如果是脚本执行
# #修改机器名
# hostnamectl set-hostnamr $1
# #修改静态网络
# addr=$2 #192.168.64.188

#安装vim 和 wget

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentoS-Base.repo.bak3
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

#创建软件安装文件夹

#配置JDK
mkdir -p /opt/soft/jdk180
jdkPath=`find /opt/ -name 'jdk*.tar.gz*'`
tar -zxf $jdkPath -C /opt/soft/jdk180 --strip-components 1
if [ ! $JAVA_HOME ]
then
echo 'export JAVA_HOME=/opt/soft/jdk180' >> /etc/profile
echo 'export CLASSPATH=.:%JAVA_HOME/lib/dt.jar:%JAVA_HOME/lib/tools.jar' >> /etc/profile
echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /etc/profile
source /etc/profile
fi
不要使用sh命令去运行脚本，直接使用source命令运行脚本就不会出现问题
