linux下安装jdk+配置多个tomcat

1.安装jdk:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
tar zvxf jdk-7u60-linux-x64.tar.gz
mv jdk1.7.0_60/ /usr/local/jdk1.7.0_60/


配置环境变量
vi /etc/profile
export JAVA_HOME=/usr/local/jdk1.7.0_60/
export CATALINA_BASE=/usr/local/tomcat

export CATALINA_HOME=/usr/local/tomcat

export CATALINA_2_BASE=/usr/local/tomcat_2

export CATALINA_2_HOME=/usr/local/tomcat_2

export PATH=$CATALINA_HOME/bin:$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/lib

source /etc/profile //让环境变量生效

2.安装tomcat:
wget http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.11/bin/apache-tomcat-7.0.11.tar.gz
tar zxf apache-tomcat-7.0.11.tar.gz
mv apache-tomcat-7.0.11 /usr/local/tomcat
mkdir -p /data/htdocs/www
cp -rf /usr/local/tomcat/webapps/* /data/htdocs/www/


3.安装多个tomcat  （需要修改tomcat配置）
 vi /etc/profile
export JAVA_HOME=/usr/local/jdk
export PATH=$CATALINA_HOME/bin:$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/lib

修改 tomcat/bin/catalina.sh

增加

export JAVA_HOME=$JAVA_HOME
export CLASSPATH=$JAVA_HOME/lib
export CATALINA_BASE=$CATALINA_2_BASE （引用上面配置的环境变量）
export CATALINA_HOME=$CATALINA_2_HOME
export PATH=$CATALINA_HOME/bin:$JAVA_HOME/bin:$PATH

每个tomcat文件都需要配置 一一对应 

然后修改

tomcat/conf/server.xml

把里面的端口换成 不要跟其他tomcat重复

比如 tomcat-1 8080 tomcat-2 8082等... 共需要修改4处端口

之后依次启动tomcat进行测试,
