tomcat环境搭建&多实例配置

sdhgf

tomcat多实例感觉在实际使用中意义不大，不过可以模拟多台TOMCAT服务器的场景，减轻实验机器压力，多应用更靠谱 LINK:tomcat多应用(虚拟主机)配置
jdk版本:jrockit-jdk1.6.0_37-R28.2.5-4.1.0
tomcat版本:apache-tomcat-7.0.39
jrockit安装位置 /usr/local/jrockit/
tomcat安装位置 /usr/local/apache-tomcat-7.0.39/
需要包apr-1.4.6.tar.gz、apr-util-1.5.1.tar.gz、jrockit-jdk1.6.0_37-R28.2.5-4.1.0-linux-ia32.bin(32位)、apache-tomcat-7.0.39.tar.gz

tar zxvf apr-1.4.6.tar.gz
cd apr-1.4.6
./configuremake && make install

tar zxvf apr-util-1.5.1.tar.gzcd apr-util-1.5.1
./configure --with-apr=/usr/local/aprmake && make install

./jrockit-jdk1.6.0_37-R28.2.5-4.1.0-linux-ia32.bin#安装第二步选择安装目录/usr/local/jrockit/ln -s -f /usr/local/jrockit/jre/bin/java /usr/bin/ln -s -f /usr/local/jrockit/bin/javac /usr/bin/

环境配置 – vim /etc/profile

#set JAVA & TOMCAT ENVIRONMENTexport JAVA_HOME=/usr/local/jrockitexport CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/libexport PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/binexport CATALINA_HOME=/usr/local/apache-tomcat-7.0.39export JAVA_HOME CLASSPATH PATH CATALINA_HOMEexport LD_LIBRARY_PATH=/usr/local/apr/lib

source /etc/profile #刷新环境变量

java -version

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06)
Oracle JRockit(R) (build R28.2.5-20-152429-1.6.0_37-20120927-1915-linux-ia32, compiled mode)
/*JAVA配置成功*/

LINK: tomcat根据日期生成日志
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
每个实例供用TOMCAT的/bin、/lib内的包，单独使用其他文件
实例都存放在tomcat的安装文件目录中，名称叫webapps1,webapps2

cd /usr/local/apache-tomcat-7.0.39/mkdir {webapps1,webapps2}cp -r {conf/,logs/,temp/,webapps/,work/} webapps1cp -r {conf/,logs/,temp/,webapps/,work/} webapps2

修改/usr/local/apache-tomcat-7.0.39/conf/server.xml

<Server port="8005" shutdown="SHUTDOWN">...  <Service name="Catalina00">...    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />...    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />...    <Engine name="Catalina00" defaultHost="localhost" jvmRoute="jvm00">...      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
        <Context path="" docBase="/usr/local/apache-tomcat-7.0.39/webapps" reloadable="true" />...      </Host>
    </Engine>
  </Service></Server>

对应webapps1/conf/server.xml、webapps2/conf/server.xml，修改端口、名称、应用位置等
分别启动对应实例

export CATALINA_BASE=$CATALINA_HOME/bin/bash $CATALINA_HOME/bin/startup.sh -Dcatalina.baseexport CATALINA_BASE=$CATALINA_HOME/webapps1/bin/bash $CATALINA_HOME/bin/startup.sh -Dcatalina.baseexport CATALINA_BASE=$CATALINA_HOME/webapps2/bin/bash $CATALINA_HOME/bin/startup.sh -Dcatalina.base
