环境:centOS 6.5(64位)、jdk8_8u5 、tomcat7.054、nginx1.47、libevent-2.0 、memcached-1.4.20
10.1.1.127 // tomcat,nginx,memcached
10.1.1.128 // tomcat
tomcat 机配置
1、卸载自带jdk ,采用rpm 包安装
rpm –qa |grep java | xargs rpm -e --nodeps //批量卸载自带的jdk相关包
2、rpm 安装
rpm -ivhjdk-8u5-linux-x64.rpm //默认安装在 /usr/java
mv 改名改为 /usr/java/jdk
java -version //验证安装成功
3、写入环境
vim /etc/profile
JAVA_HOME=/usr/java/jdk
JRE_HOME=/usr/java/jdk/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH
source /etc/profile // 环境生效
4.解压tomcat 测试运行
tar –zxf apache-tomcat-7.0.54.tar.gz -C/usr/local
mv apache-tomcat-7.054 tomcat
vim/etc/sysconfig/iptables //防火墙开放8080端口
-A RH-Firewall-1-INPUT -m state --state NEW -mtcp -p tcp --dport 8080 -j ACCEPT
service iptables restart
http://10.1.1.127:8080/ //开启tomcat,测试tomcat安装成功
5.导入 msm-1.7包到 tom/lib/ ( tomcat 节点都要放

6.更改tomcat session保存方式(Non-Sticky,kryo
vim conf/context.xml
memcachedNodes="n1:10.1.1.217:11211" sticky="false" lockingMode="auto" sessionBackupAsync="false" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" sessionBackupTimeout="1000" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" /> //参数用法官方文档 https://code.google.com/p/memcached-session-manager/wiki/SetupAndConfiguration 章节Overviewover memcached-session-manager configuration attributes nginx 安装配置 1.源码包安装 #yum install pcre* //nginx 依赖pcre类库 #useradd nginx #tar xf /share/soft/lamp/nginx/nginx-1.4.7.tar.gz-C /usr/src/ #cd /usr/src/nginx-1.4.7 #./configure --prefix=/usr/local/nginx--user=nginx --group=nginx --with-http_gzip_static_module --with-http_stub_status_module # make && make install 2.nginx 反向代理,实现负载均衡代理后面两台tomcat 服务器 user nginxnginx; worker_processes 5; error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; events { worker_connections 1024; use epoll; } http { upstreamsession { server 10.1.1.217:8080weight=1 max_fails=2 fail_timeout=30s; server 10.1.1.218:8080weight=1 max_fails=2 fail_timeout=30s; } server { listen 80; server_name 10.1.1.217; root /nginxroot/; location~ \.(txt|jsp)$ { proxy_passhttp://session; } proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; } } mkdir /nginxroot/ //以上是简单的实现的是对jsp访问的均衡调度,实验随便改的 memcached 的安装 //先安装libevent(memcached依赖libevent) 1.安装 #tar zxvf libevent-2.0.21-stable.tar.gz #cd zxvf libevent-2.0.21-stable # ./configure --prefix=/usr #make && make install # tar zxvf memcached-1.4.20.tar.gz #cd memcached-1.4.20 #./configure --with-libevent=/usr #make && make install 2.启动,关闭命令 //启动 -d 后台运行 –m 内存大小 –p 端口 –c 最大并发数 /usr/local/bin/memcached -d -m 128 -u root -p11211 -c 256 -P /var/run/memcached.pid kill `cat /var/run/memcached1.pid` //关闭 http://hxq0506.iteye.com/blog/1388971 //参考链接 测试: 启动顺序 tomcat – nginx – memcached 测试页面test.jsp,放入webapps/ROOT: Server Info: SessionID:<%=session.getId()%> SessionIP:<%=request.getServerName()%> SessionPort:<%=request.getServerPort()%> <% out.println("127"); //标记后端节点 %> 结果:session 保持不变
