nginx+tomcat+memcached构建session共享集群
一、安装配置tomcat 配置前说明： 系统为centos7 m1.xsllqs.com地址为192.168.1.107 c1.xsllqs.com地址为192.168.1.114 c2.xsllqs.com地址为192.168.1.113 安装tomcat需要配合JDK使用，JDK有oracle JDK和open JDK两种 oracle JDK8的下载地址：http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html tomcat的下载地址：http://tomcat.apache.org/ c1.xsllqs.com(192.168.1.114)下载安装jdk（建议加载到本地在传上去）和tomcat [root@c1~]#wgethttp://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm [root@c1~]#wgethttp://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz [root@c1~]#ls apache-tomcat-8.0.36.tar.gzjdk-8u73-linux-x64.rpm [root@c1~]#yuminstalljdk-8u73-linux-x64.rpm [root@c1~]#vim/etc/profile.d/java.sh exportJAVA_HOME=/usr/java/latest exportPATH=$JAVA_HOME/bin:$PATH [root@c1~]#./etc/profile.d/java.sh [root@c1~]#java-version javaversion"1.8.0_73" [root@c1~]#tarxfapache-tomcat-8.0.36.tar.gz-C/usr/local [root@c1~]#cd/usr/local/ [root@c1local]#ln-svapache-tomcat-8.0.36tomcat "tomcat"->"apache-tomcat-8.0.36" [root@c1tomcat]#vim/etc/profile.d/tomcat.sh exportCATALINA_HOME=/usr/local/tomcat exportPATH=$CATALINA_HOME/bin:$PATH [root@c1tomcat]#./etc/profile.d/tomcat.sh c2.xsllqs.com(192.168.1.113)下载安装jdk和tomcat [root@c2~]#wgethttp://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm [root@c2~]#wgethttp://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz [root@c2~]#ls apache-tomcat-8.0.36.tar.gzjdk-8u73-linux-x64.rpm [root@c2~]#yuminstalljdk-8u73-linux-x64.rpm [root@c2~]#vim/etc/profile.d/java.sh exportJAVA_HOME=/usr/java/latest exportPATH=$JAVA_HOME/bin:$PATH [root@c2~]#./etc/profile.d/java.sh [root@c2~]#java-version javaversion"1.8.0_73" [root@c2~]#tarxfapache-tomcat-8.0.36.tar.gz-C/usr/local [root@c2~]#cd/usr/local/ [root@c2local]#ln-svapache-tomcat-8.0.36tomcat "tomcat"->"apache-tomcat-8.0.36" [root@c2tomcat]#vim/etc/profile.d/tomcat.sh exportCATALINA_HOME=/usr/local/tomcat exportPATH=$CATALINA_HOME/bin:$PATH [root@c2tomcat]#./etc/profile.d/tomcat.sh 二、修改tomcat配置文件 [root@c1tomcat]#cd/usr/local/tomcat/webapps/ [root@c1webapps]#mkdirmyapp/{lib,classes,WEB-INF,META-INF}-pv [root@c1webapps]#cdmyapp/ 添加c1和c2的主页文件 [root@c1myapp]#vimindix.jsp <%@pagelanguage="java"%> <html> <head><title>Tomcat1</title></head> <body> <h1><fontcolor="red">c1.xsllqs.com</font></h1> <tablealign="centre"border="1"> <tr> <td>SessionID</td> <%session.setAttribute("xsllqs.com","xsllqs.com");%> <td><%=session.getId()%></td> </tr> <tr> <td>Createdon</td> <td><%=session.getCreationTime()%></td> </tr> </table> </body> </html> [root@c2myapp]#vimindix.jsp <%@pagelanguage="java"%> <html> <head><title>Tomcat2</title></head> <body> <h1><fontcolor="blue">c2.xsllqs.com</font></h1> <tablealign="centre"border="1"> <tr> <td>SessionID</td> <%session.setAttribute("xsllqs.com","xsllqs.com");%> <td><%=session.getId()%></td> </tr> <tr> <td>Createdon</td> <td><%=session.getCreationTime()%></td> </tr> </table> </body> </html> 修改tomcat-user.xml（c1和c2都要改） [root@c1conf]#vim/usr/local/tomcat/conf/tomcat-users.xml #在</tomcat-users>中添加 <rolerolename="manager-gui"/> <rolerolename="admin-gui"/> <userusername="tomcat"password="<tomcat>"roles="manager-gui,admin-gui"/> 修改server.xml（c1和c2都要改） [root@c1conf]#vim/usr/local/tomcat/conf/server.xml #修改主配置文件,appBase后面是应用的相对路径也可以是绝对路径 <Hostname="localhost"appBase="webapps" unpackWARs="true"autoDeploy="true"> #这里是访问日志的设置 <ValveclassName="org.apache.catalina.valves.AccessLogValve"directory="logs" prefix="localhost_access_log"suffix=".txt" pattern="%h%l%u%t"%r"%s%b"/> #这里设置Context调用msm需要的组件，m1为主c2为备，因为我这里只有3台机器所以把c2作为备，正常情况是4台，2台memcached和2台tomcat <Contextpath="/myapp"docBase="/usr/local/tomcat/webapps/myapp"reloadable="true"> <ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="m1:192.168.1.107:11211,c2:192.168.1.113:11211" failoverNodes="m1" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory" /> </Context> 测试配置文件 [root@c1~]#catalina.shconfigtest [root@c2~]#catalina.shconfigtest [root@c1~]#catalina.shstart [root@c2~]#catalina.shstart 三、安装msm c1和c2上下载msm需要的jar包 [root@c1~]#wgethttp://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager/1.9.4/memcached-session-manager-1.9.4.jar [root@c1~]#wgethttp://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager-tc8/1.9.4/memcached-session-manager-tc8-1.9.4.jar [root@c1~]#wgethttp://repo1.maven.org/maven2/de/javakaffee/msm/msm-javolution-serializer/1.9.4/msm-javolution-serializer-1.9.4.jar [root@c1~]#wgethttp://repo1.maven.org/maven2/net/spy/spymemcached/2.11.1/spymemcached-2.11.1.jar [root@c1~]#wgethttp://www.java2s.com/Code/JarDownload/javolution/javolution-5.4.3.1.jar.zip [root@c1~]#mvjavolution-5.4.3.1.jarmemcached-session-manager-1.9.4.jarmemcached-session-manager-tc8-1.9.4.jarmsm-javolution-serializer-1.9.4.jarspymemcached-2.11.1.jar/usr/local/tomcat/lib/ m1和c2上安装memcached [root@m1~]#yuminstallmemcached [root@c2~]#yuminstallmemcached m1上安装nginx修改nginx的配置文件 [root@m1~]#yuminstallnginx [root@m1~]#vim/etc/nginx/nginx.conf #server外加入 upstreamtcsrvs{ server192.168.1.114:8080; server192.168.1.113:8080; } #server内加入 location~*\.(jsp|do)${ proxy_passhttp://tcsrvs; } [root@m1~]#nginx-t 启动服务 [root@m1~]#systemctlstartnginx.service [root@m1~]#systemctlstartmemcached [root@c2~]#systemctlstartmemcached 四、测试
