下载tomcat： wget http://mirrors.shu.edu.cn/apache/tomcat/tomcat-8/v8.5.34/bin/apache-tomcat-8.5.34.tar.gz

下载JDK： wget http://download.oracle.com/otn-pub/java/jdk/8u181-b13/96a7b8442fe848ef90c96a2fad6ed6d1/jdk-8u181-linux-x64.rpm?AuthParam=1536721970_38dbf1e81e1c24c45ef2e0ee119b29a4

安装jdk： rpm -ivh jdk-8u181-linux-x64.rpm?AuthParam=1536721970_38dbf1e81e1c24c45ef2e0ee119b29a4 安装目录： ls /usr/java 配置环境变量： #vi /etc/profile.d/java.sh export JAVA_HOME=/usr/java/latest export PATH=$JAVA_HOME/bin:$PATH 重读配置： #. /etc/profile.d/java.sh 查看版本：

java -version

java version "1.8.0_181" Java(TM) SE Runtime Environment (build 1.8.0_181-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode) 查看环境变量： ]# echo $JAVA_HOME /usr/java/latest

解压tomca至usr/local： tar xf apache-tomcat-8.5.34.tar.gz -C /usr/local/ ln -sv apache-tomcat-8.5.34 tomcat

添加环境变量： vi /etc/profile.d/tomcat.sh export CATALINA_HOME=/usr/local/tomcat export PATH=$CATALINA_HOME/bin:$PATH 重读：. /etc/profile.d/tomcat.sh 测试：

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/java/latest Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Server version: Apache Tomcat/8.5.34 Server built: Sep 4 2018 22:28:22 UTC Server number: 8.5.34.0 OS Name: Linux OS Version: 3.10.0-514.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_181-b13 JVM Vendor: Oracle Corporation 测试配置语法： catalina.sh configtest 启动yomcat：

catalina.sh start

添加第一个java程序： 1、创建目录结构 #mkdir myapp/{lib,classes,WEB-INF,META-INF} -pv mkdir: 已创建目录 "myapp/lib" mkdir: 已创建目录 "myapp/classes" mkdir: 已创建目录 "myapp/WEB-INF" mkdir: 已创建目录 "myapp/META-INF" 2、编写程序

vi myapp/index.jsp

<%@ page language="java" %> <%@ page import="java.util.*" %> <html> <head> <title>JSP Test Page</title> </head> <body> <% out.println("hello world"); %> </body> </html>

配置管理界面：添加管理员账号和密码： #vi /usr/local/tomcat/conf/tomcat-users.xml <role rolename="manager-gui"/> <user username="tomcat" password="tomcat1" roles="manager-gui"/>

配置远程访问manager： tomat_home/conf/Catalina/localhost/下添加manager.xml <Context privileged="true" antiResourceLocking="false" docBase="${catalina.home}/webapps/manager"> <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^.*$" /> </Context>
配置host manager：

vi tomcat-users.xml

#vim webapps/host-manager/META-INF/context.xml

	<Context antiResourceLocking="false" privileged="true" >
	<Valve className="org.apache.catalina.valves.RemoteAddrValve"
    		 allow="^.*$" />  #修改这里
		</Context>

创建目录文件： mkdir -pv /data/{webapps,logs} 拷贝测试文件： cp -r /usr/local/tomcat/webapps/myapp/* /data/webapps/ 编辑tomcat配置文件： #vi server.xml </Host> <Host name="web.shengjing360.com" appBase="/data/webapps" unpackWARs="true" autoDeploy="true"> <Context path="" docBase="/data/webapps" reloadable="true" /> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> 配置hosts文件，然后测试虚拟机：http://web.shengjing360.com:8080/

tomcat基于httpd负载均衡示例： vi /etc/httpd/conf.d/vhosts.conf

基于http： proxy balancer://lbcluster1> balancermember http://192.168.102.44:8080 loadfactor=10 route=TomcatA balancermember http://192.168.102.46:8080 loadfactor=10 route=TomcatB </proxy>
