apache2和jk和tomcat安装笔记-ubuntu

2019独角兽企业重金招聘Python工程师标准>>>

Ubuntu是个很奇怪的系统。。。安装完的路径完全和官网下载安装的不一样

 

 

Tomcat一定要用7.0.5X      别的有的不好使各种报错

环境变量里一定要有JAVA_HOME,PATH里一定包含JAVA_HOME

cat /etc/hosts

127.0.0.1       localhost

127.0.0.1       umw

127.0.0.1       192.168.0.121

网络对应关系需要把局域网ip对应本地ip

 

如果想获取客户端真实的ip应该添加remoteip这个模块

 

apt-get install apache2 libapache2-mod-jk

安装apache2和jk

 

Apache2的jk插件在/etc/apache2/mods-avalibale/jk.conf

         而jk的workers.propertiy在/etc/libapache2-mod-jk/workers.propertiy

在property里指定java环境和多个tomcat

workers.java_home=/usr/lib/jvm/java7

  worker.list=loadbalancer,jkstatus

        worker.tomcat1.type=ajp13  

        worker.tomcat1.host=localhost

        worker.tomcat1.port=8009 

        worker.tomcat1.lbfactor=1

        worker.tomcat1.socket_keepalive=1 

 

        worker.tomcat2.type=ajp13

        worker.tomcat2.host=localhost

        worker.tomcat2.port=9009

        worker.tomcat2.lbfactor=1

        worker.tomcat2.socket_keepalive=1

        worker.jkstatus.type=status

        worker.loadmanager.sticky_session=True

        worker.loadbalancer.type=lb  

        worker.loadbalancer.balance_workers=tomcat1,tomcat2

这个status一定要这么写 哎 累死我了各种试

 

在/etc/apache2/mods-avalibale/jk.conf编辑如下

加上

JkMount /*  loadbalancer

     JkMount /jkstatus jkstatus 

 

找到 Deny from all注释掉

 下面改为        Allow from all

 

 

Tomcat的配置

conf目录下

编辑web.xml

最后一行</web-app>上面加上<distributable/> 

（使多个session共享）

在server.xml里配置session和端口

<Connector port="8080" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

这两句 第一个tomcat不用变 第二个改端口可以分别是 9090和9009，响应的端口改为9443

找到engine标签 换成一下配置

jvmRoute第二个tomcat写tomcat2

Receiver的address改为自己局域网的ip，port第二个tomcat改为4002

如果你不是在一台机器上布置两个tomcat，就不用改

 

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

 

   <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"   

                    channelSendOptions="8">

 

             <Manager className="org.apache.catalina.ha.session.DeltaManager"   

                      expireSessionsOnShutdown="false"   

                      notifyListenersOnReplication="true"/>

 

             <Channel className="org.apache.catalina.tribes.group.GroupChannel">

               <Membership className="org.apache.catalina.tribes.membership.McastService"   

                           address="228.0.0.4"   

                           port="45564"   

                           frequency="500"   

                           dropTime="3000"/>

               <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"   

                         address="192.168.0.121"

                         port="4001"

                         autoBind="100"   

                         selectorTimeout="5000"   

                         maxThreads="6"/>

 

               <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">

                 <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>

               </Sender>

               <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>

               <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>

             </Channel>

 

             <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"   

                    filter=""/>

             <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

 

             <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"   

                       tempDir="/tmp/war-temp/"   

                       deployDir="/tmp/war-deploy/"   

                       watchDir="/tmp/war-listen/"   

                       watchEnabled="false"/>

 

             <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

             <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

           </Cluster>

 

 

Apache2的配置

在/etc/apache2/apache2.conf里

空白处加

ServerName localhost:80

DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php3 index.pl index.xhtml

在/etc/apache2/site-avaliable里编辑000-default.conf设置两个tomcat的虚拟主机目录

为了可以通过端口访问两个tomcat，如果不想让两个tomcat暴露的话不需要设置这个虚拟主机

<VirtualHost *:8080>

           ServerAdmin webmaster@localhost

           DocumentRoot /opt/tomcat5/webapps

           ErrorLog /var/log/apache2/idealerror.log

           LogLevel warn

           CustomLog /var/log/apache2/idealaccess.log combined

           <Directory "/opt/tomcat5/webapps/">

               Options FollowSymLinks

               AllowOverride None

              Order allow,deny

              Allow from all

           </Directory>

  </VirtualHost>

  <VirtualHost *:9090>

          ServerAdmin webmaster@localhost

          DocumentRoot /opt/tomcat6/webapps

          ErrorLog /var/log/apache2/idea2error.log

          LogLevel warn

          CustomLog /var/log/apache2/idea2access.log combined

          <Directory "/opt/tomcat6/webapps/">

              Options FollowSymLinks

              AllowOverride None

             Order allow,deny

              Allow from all

           </Directory>

  </VirtualHost>

先启动tomcat再启动apache restart

直接访问局域网地址192.168.0.121就会跳转到其中一台tomcat的主页

访问http://192.168.0.121/jkstatus就可以查看apache2的状态

然后你就可以吧项目考到tomcat的webapps目录下来（两个tomcat都要考哦），重启tomcat访问项目

 

Apache2的相关命令

/etc/init.d/apache2 force-reload 重载

/etc/init.d/apache2 restart 重启

a2enmod添加插件（可查看jk是否被启用）

a2dismod卸载插件

错误日志文件 在var/log/apache2文件夹中其中有mod_jk的日志文件，

也可以查看tomcat目录下的logs文件夹内的localhost_access_log.2014-12-03.txt文件来查看tomcat与apache之间的通讯信息（比较多 看的眼花缭乱的）
