1、准备工具 Xshell和Xftp,连接上服务器

2、下载jdk-7u76-linux-x64.tar.gz 安装包 到 /usr/local/目录

3、解压缩tar xvf jdk-7u76-linux-x64.tar.gz 到目录/usr/local/jdk ， 删除压缩包 rmjdk-7u76-linux-x64.tar.gz

4、设置jdk环境变量 vim /etc/profile

export JAVA_HOME=/usr/local/jdk
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=./:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

5、使profile配置生效。命令行：source /etc/profile

6、验证安装 java -version 、 javac

7、下载apache-tomcat-8.0.39.tar.gz 到/usr/local/目录

8、解压缩tar xvf apache-tomcat-8.0.39.tar.gz 到目录/usr/local/tomcat ， 删除压缩包 rm apache-tomcat-8.0.39.tar.gz

9、配置环境变量 vim /etc/profile.d/tomcat.sh

CATALINA_BASE=/usr/local/tomcat
PATH=$CATALINA_BASE/bin:$PATH
export PATH CATALINA_BASE

. /etc/profile.d/tomcat.sh

10、 配置server.xml

<Service name="Catalina">

    <Connector port="80" protocol="HTTP/1.1"  
               connectionTimeout="20000"
               redirectPort="8443" />

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

    <Engine name="Catalina" defaultHost="x.x.x.x">
 
      <Realm className="org.apache.catalina.realm.LockOutRealm">
 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="x.x.x.x"  appBase="project/ccnulife"
            unpackWARs="true" autoDeploy="true">
 
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
			   
    	<Context path="" docBase="/usr/local/apache-tomcat-8.0.39/ccnulife" reloadable="true" crossContext="true"/>

      </Host>
	  
    </Engine>
