Tomcat和java的安装

java开发环境搭建
1、将普通用户添加到sudoers中
   进入root模式
       编辑添加
           visudo
           username ALL=(ALL) ALL


2、安装jdk
   检查是否有jdk
       java -version

   查看jdk信息
       rpm -qa | grep java

   卸载openjdk
       rpm -e --nodeps tzdata-java-2015g-1.el7.noarch
       rpm -e --nodeps java-1.8.0-openjdk-1.8.0.65-3.b17.el7.x86_64


   新建java安装目录
       mkdir /usr/java

rpm软件包安装
       rpm -ivh jdk-*.rpm

       ###gz压缩包安装
           tar -xzvf jdk-*.tar.gz

安装tomcat
   创建安装目录
       mkdir /var/local

   下载
       cd /var/local
       wget http://apache.fayea.com/apache-mirror/tomcat/tomcat-7/v7.0.57/bin/apache-tomcat-7.0.57.tar.gz

   解压tomcat.tar.gz
       tar -xzvf apache-tomcat-*.tar.gz

   将目录改名为tomcat
       mv apache-tomcat-* tomcat

   启动tomcat
       /var/local/tomcat/bin/startup.sh

   Linux 下tomcat开机自启动
   修改Tomcat/bin/startup.sh 为:
           export JAVA_HOME=/usr/java/jdk1.8.0_121
           export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
           export PATH=$PATH:$JAVA_HOME/bin
           export CATALINA_HOME=/usr/local/tomcat
           /var/local/tomcat/bin/catalina.sh start

在/etc/rc.d/rc.local中加入:
/var/local/tomcat/bin/startup.sh

方法二：
1、把下面的代码保存为tomcat文件，并让它成为可执行文件 chmod 755 tomcat.
#!/bin/bash

if [ -f /etc/init.d/functions ]; then
           . /etc/init.d/functions
       elif [ -f /etc/rc.d/init.d/functions ]; then
           . /etc/rc.d/init.d/functions
       else
           echo -e "/atomcat: unable to locate functions lib. Cannot continue."
           exit -1
       fi

RETVAL=$?
CATALINA_HOME="/usr/local/tomcat"

case "$1" in
       start)
           if [ -f $CATALINA_HOME/bin/startup.sh ];
           then
               echo $"Starting Tomcat"
               $CATALINA_HOME/bin/startup.sh
           fi
       ;;
       stop)
           if [ -f $CATALINA_HOME/bin/shutdown.sh ];
       then
           echo $"Stopping Tomcat"
           $CATALINA_HOME/bin/shutdown.sh
       fi
       ;;
       *)
       echo $"Usage: $0 {start|stop}"
       exit 1
       ;;
       esac

exit $RETVAL

2、将tomcat文件拷贝到/etc/init.d/下，并运行：chkconfig --add tomcat

3、在tomcat/bin/catalina.sh文件中加入以下语句：
           export JAVA_HOME=/YOURPATH/tomcat/jdk
           export CATALINA_HOME=/YOURPATH/tomcat
           export CATALINA_BASE=/YOURPATH/tomcat
           export CATALINA_TMPDIR=/YOURPATH/tomcat/temp

启动tomcat： service tomcat start
停止tomcat: service tomcat stop
