• tomcat生产环境JDK部署及虚拟主机等常用配置详解


    jdk和tomcat环境部署:

    1、删除系统自带的openjdk

    # java -version
    java version "1.7.0_45"
    OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
    OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
    # rpm -qa | grep java
    tzdata-java-2013g-1.el6.noarch
    java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
    java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
    # rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
    # rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64

    2、安装jdk-7u79

    # rpm -ivh jdk-7u79-linux-x64.rpm 
    # vim /etc/profile.d/java.sh

    export JAVA_HOME=/usr/java/latest
    export PATH=$JAVA_HOME/bin:$PATH

    验证是否安装成功
    # java -version
    java version "1.7.0_79"
    Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
    Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

    3、部署tomcat

    # unzip apache-tomcat-7.0.69.zip
    # cp -r apache-tomcat-7.0.69 /usr/local/
    # cd /usr/local
    # ln -sv apache-tomcat-7.0.69 tomcat

    # vim /etc/profile.d/tomcat.sh
    export CATALINA_HOME=/usr/local/tomcat
    export PATH=$CATALINA_HOME/bin:$PATH
    # . /etc/profile.d/tomcat.sh
    # chmod +x /usr/local/tomcat/bin/*.sh


    验证是否成功
    # catalina.sh version
    Using CATALINA_BASE:   /usr/local/tomcat
    Using CATALINA_HOME:   /usr/local/tomcat
    Using CATALINA_TMPDIR: /usr/local/tomcat/temp
    Using JRE_HOME:        /usr
    Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
    Server version: Apache Tomcat/7.0.69
    Server built:   Apr 11 2016 07:57:09 UTC
    Server number:  7.0.69.0
    OS Name:        Linux
    OS Version:     2.6.32-431.el6.x86_64
    Architecture:   amd64
    JVM Version:    1.7.0_79-b15
    JVM Vendor:     Oracle Corporation

    将tomcat加入服务脚本
    # vim /etc/init.d/tomcat


    #!/bin/sh
    # Tomcat init script for Linux.
    #
    # chkconfig: 2345 96 14
    # description: The Apache Tomcat servlet/JSP container.
    # JAVA_OPTS='-Xms64m -Xmx128m'
    JAVA_HOME=/usr/java/latest
    CATALINA_HOME=/usr/local/tomcat
    export JAVA_HOME CATALINA_HOME
    
    
    case $1 in
    start)
      exec $CATALINA_HOME/bin/catalina.sh start ;;
    stop)
      exec $CATALINA_HOME/bin/catalina.sh stop;;
    restart)
      $CATALINA_HOME/bin/catalina.sh stop
      sleep 2
      exec $CATALINA_HOME/bin/catalina.sh start ;;
    configtest)
      exec $CATALINA_HOME/bin/catalina.sh configtest ;;
    *)
      echo "Usage: `basename $0` {start|stop|restart}"
      exit 1
      ;;
    esac


    # chmod +x /etc/init.d/tomcat
    # chkconfig add tomcat
    # service tomcat start


    tomcat配置常用案例:


    1、定义同时监听两个端口80和8080:


    以下为connector常用属性的说明:
    1) address:指定连接器监听的地址,默认为所有地址,即0.0.0.0;
    2) maxThreads:支持的最大并发连接数,默认为200;
    3) port:监听的端口,默认为0;
    4) protocol:连接器使用的协议,默认为HTTP/1.1,定义AJP协议时通常为AJP/1.3;
    5) redirectPort:如果某连接器支持的协议是HTTP,当接收客户端发来的HTTPS请求时,则转发至此属性定义的端口;
    6) connectionTimeout:等待客户端发送请求的超时时间,单位为毫秒,默认为60000,即1分钟;
    7) enableLookups:是否通过request.getRemoteHost()进行DNS查询以获取客户端的主机名;默认为true;
    8) acceptCount:设置等待队列的最大长度;通常在tomcat所有处理线程均处于繁忙状态时,新发来的请求将被放置于等待队列中;

    <Connector port="80" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="443" />
        <Connector port="8080" address="127.0.0.1" maxThreads="1024" enableLookups="false" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="443" />
    


    2、定义host主机

    # mkdir /www/webapps/ROOT -pv
    # vim /www/webapps/ROOT/index.jsp
    <%@ page language="java" %>
    <%@ page import="java.util.*" %>
    <html>
    <head>
    <title>jsp page test1</title>
    </head>
    <body>
    <% out.println("hello world!"); %>
    </body>
    </html>

    # vim /usr/local/tomcat/conf/server.xml


    <Host name="www.a.com" appBase="/www/webapps" unpackWARS="true" autoDeploy="true">
          <Context path="" docBase="ROOT" reloadable="true" />
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="a.com_access_log." suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
          </Host>


    在host主机中添加另外的应用


    # mkdir /www/webapps/testapp
    # cp /www/webapps/ROOT/index.jsp /www/webapps/testapp/


    <Host name="www.a.com" appBase="/www/webapps" unpackWARS="true" autoDeploy="true">
          <Context path="" docBase="ROOT" reloadable="true" />
          <Context path="/test" docBase="testapp" reloadable="true" />
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="a.com_access_log." suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
          </Host>



    3、添加tomcat应用的status和应用的管理


    # vim /usr/local/tomcat/conf/tomcat-users.xml

    <role rolename="manage-gui" />
    <user username="tomcat" password="tomcat" roles="tomcat,manager-gui,admin-gui" />
