server 部署步骤备份

1. centos7.2 upload tomcat jdk for centos

2. 环境变量
   echo welcome to heima server
   cd /root/server
   pwd
   export JAVA_HOME=./jdk1.8.0_131/jre
   export PATH=$PATH:./jdk1.8.0_131/jre/bin:./apache-tomcat-8.5.15/bin
   export TOMCAT_HOME=./apache-tomcat-8.5.15/bin
   export CATALINA_HOME=./apache-tomcat-8.5.15
   chmod u+x $TOMCAT_HOME/startup.sh
   $TOMCAT_HOME/startup.sh

3. 设置开机启动 /etc/rc.d/rc.local ( 需要chmod 777)
   启动start-server.sh

4. tomcat启动卡死 centos随机数问题
   修改 ./jdk1.8.0_131/jre/lib/security
   securerandom.source=file:/dev/./urandom
