1.tomcat
(1)下载 lftp 192.168.2.251
sh /root/jdk-6u32-linux-x64.bin
mv /root/jdk1.6.0_32/ /usr/local/lnmp/jdk
(2)命令 vim /etc/profile
export JAVA_HOME=/usr/local/lnmp/jdk(zuihou)
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile
(3)检测 echo $JAVA_HOME
/usr/local/lnmp/jdk
echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/lnmp/mysql/bin:/root/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/php/bin/:/usr/local/lnmp/jdk/bin
echo $CLASSPATH

which java
/usr/local/lnmp/jdk/bin/java
which javac
/usr/local/lnmp/jdk/bin/javac
(4)java测试 vim /root/test.java
public class test {
public static void main(String[] args)
{
System.out.println("hello");
}
}
javac test.java
java test
hello
2.整合
(1)安装tomcat
解压 tar zfx apache-tomcat-7.0.37.tar.gz -C /usr/local/lnmp/
重命名 mv /usr/local/lnmp/apache-tomcat-7.0.37/ /usr/local/lnmp/tomcat
执行 /usr/local/lnmp/tomcat/bin/startup.sh
端口 netstat -antlp (8080)
(2)测试页面 vim /usr/local/lnmp/tomcat/webapps/ROOT/test.jsp
server220 The time is: <%=new java.util.Date()%>
（3）配置 vim /usr/local/lnmp/nginx/conf/nginx.conf
location ~ \.jsp$ { （69）
proxy_pass http://127.0.0.1:8080;
}
(4)重启 nginx -s reload
(5)测试 192.168.2.220:8080
192.168.2.220/test.jsp
3.附带均衡
需要2个测试机
*1.副机
(1)建目录 mkdir /usr/local/lnmp
(2)profiel vim /etc/profile
export JAVA_HOME=/usr/local/lnmp/jdk
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile
(3)sh /usr/local/lnmp/tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/lnmp/tomcat
Using CATALINA_HOME: /usr/local/lnmp/tomcat
Using CATALINA_TMPDIR: /usr/local/lnmp/tomcat/temp
Using JRE_HOME: /usr/local/lnmp/jdk
Using CLASSPATH: /usr/local/lnmp/tomcat/bin/bootstrap.jar:/usr/local/lnmp/tomcat/bin/tomcat-juli.jar
(4)端口 netstat -antlp (880)
(5)测试页面 vim /usr/local/lnmp/tomcat/webapps/ROOT/test.jsp
server105 The time is: <%=new java.util.Date()%>
*2.主机
(1)复制 scp -r /usr/local/lnmp/jdk/ 192.168.2.105:/usr/local/lnmp/
scp -r /usr/local/lnmp/tomcat/ 192.168.2.105:/usr/local/lnmp/
(2)配置 vim /usr/local/lnmp/nginx/conf/nginx.conf
upstream westos {(19)
server 192.168.2.105:8080;
server 192.168.2.220:8080;
}
location ~ \.jsp$ { (68)
proxy_pass http://westos;
}
(3)重启 nginx -s reload
(4)测试 192.168.2.220/test.jsp (变化)
