部署 Apache
[root@localhost ~]# yum install httpd httpd-devel
[root@localhost ~]# echo “apache html test” > /var/www/html/index.html
[root@localhost ~]# cd /tmp
[root@localhost tmp]# tar zxvf tomcat-connectors-1.2.32-src.tar.gz
[root@localhost tmp]# cd tomcat-connectors-1.2.32-src/native
[root@localhost native]# ./configure --with-apxs=/usr/bin/apxs #如果没有/usr/bin/apxs需要安装httpd-devel
aclocal-1.15 执行autoreconf -ivf yum install automake autoconf
[root@localhost native]# make && make install
[root@localhost native]# cp ../conf/httpd-jk.conf /etc/httpd/conf.d/jk.conf
[root@localhost native]# vim /etc/httpd/conf.d/jk.conf
JkMount /*.jsp wlb
[root@localhost native]# cp ../conf/workers.properties /etc/httpd/conf
[root@localhost native]# vim /etc/httpd/conf/workers.properties
worker.list=wlb
worker.wlb.type=lb
worker.wlb.balance_workers=tomcat1,tomcat2
worker.tomcat1.type=ajp13
worker.tomcat1.host=192.168.122.20
worker.tomcat1.port=8009
worker.tomcat1.lbfactor=1
worker.tomcat2.type=ajp13
worker.tomcat2.host=192.168.122.30
worker.tomcat2.port=8009
worker.tomcat2.lbfactor=1
[root@localhost native]# service httpd start
部署 Tomcat 1 & Tomcat 2
[root@localhost ~]# service httpd stop
[root@localhost ~]# cd /tmp
[root@localhost tmp]# chmod +x jdk-6u27-linux-i586.bin
[root@localhost tmp]# ./jdk-6u27-linux-i586.bin
[root@localhost tmp]# mv jdk1.6.0_27/ /usr/local/jdk
使用1.8版本以下的openjdk
yum install java-1.7.0-openjdk.x86_64
[root@localhost tmp]# vim /etc/bashrc
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64/jre/
export JAVA_BIN=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64/jre/bin/
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
[root@localhost tmp]# source /etc/bashrc
[root@localhost tmp]# java -version
[root@localhost tmp]# tar zxf apache-tomcat-6.0.32.tar.gz
[root@localhost tmp]# mv apache-tomcat-6.0.32 /usr/local/tomcat
[root@localhost tmp]# cd /usr/local/tomcat/bin
[root@localhost bin]# ./startup.sh
[root@localhost bin]# vim /usr/local/tomcat/webapps/ROOT/index.jsp
#Tomcat2 修改为别的颜色
<%= request.getSession().getId() %>
Tomcat 1
#Tomcat 2阶段测试
1.访问 index.html 由 Aapche 处理,
2.访问 index.jsp 交给 Tomcat 1 与 Tomcat 2 负载处理,
3.访问 index.jsp 时在 Tomcat 1 与 Tomcat 2 之间进行切换,但是 session_id 也随之变化
部署 Memcache 1 & Memcache 2
[root@localhost tmp]# tar xf libevent-2.0.15-stable.tar.gz
[root@localhost tmp]# cd libevent-2.0.15-stable
[root@localhost libevent-2.0.15-stable]# ./configure && make && make install
[root@localhost tmp]# tar xf memcached-1.4.5.tar.gz
[root@localhost tmp]# cd memcached-1.4.5
[root@localhost memcached-1.4.5]# ./configure && make && make install
[root@localhost memcached-1.4.5]# memcached -h
[root@localhost memcached-1.4.5]# memcached -p 11211 -l 192.168.122.40 -u root -m 10 -c 10 -vvv -f 1.2 -n 60
部署 Tomcat 1 & Tomcat 2 支持连接 Memcached
[root@localhost tmp]# cp session/*.jar /usr/local/tomcat/lib
[root@localhost tmp]# vim /usr/local/tomcat/conf/context.xml
memcachedNodes="n1:192.168.122.40:11211,n2:192.168.122.50:11211"
failoverNodes="n1"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
注意：定义内容要写在<Context></Context>里面
[root@localhost tmp]# /usr/local/tomcat/bin/shutdown.sh
[root@localhost tmp]# /usr/local/tomcat/bin/startup.sh
最终测试
1.访问 index.html 由 Aapche 处理,
2.访问 index.jsp 交给 Tomcat 1 与 Tomcat 2 负载处理,
3.访问 index.jsp 时在 Tomcat 1 与 Tomcat 2 之间进行切换,并且 session_id 不会变化
