安装配置Nginx+tomcat负载均衡集群服务器环境

jdk-6u22-linux-x64.bin、apache-tomcat-6.0.26.tar.gz

二、安装

1、安装JDK

./jdk-6u22-linux-i586.bin

mv jdk1.6.0_22/ /usr/local/

2、安装tomcat

tar zxvf apache-tomcat-6.0.26.tar.gz

mv apache-tomcat-6.0.26 /usr/local/

cd /usr/local/

mv apache-tomcat-6.0.26/ tomcat1

3、配置环境变量

vi /etc/profile

JAVA_HOME=/usr/local/jdk1.6.0_22

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

PATH=$JAVA_HOME/bin:$PATH

export JAVA_HOME CLASSPATH PATH

source /etc/profile

4、测试

java -version

java version "1.6.0_22"

Java(TM) SE Runtime Environment (build 1.6.0_22-b04)

Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

5、用普通用户启动tomcat

cd /usr/local/tomcat1/bin

tar zxvf jsvc.tar.gz

cd jsvc-src

chmod +x configure

./configure --with-java=/usr/local/jdk1.6.0_22

make

6、创建用户

useradd tomcat

7、修改配置文件

vi server.xml（修改如下内容）

8、创建启动脚本

vi /etc/init.d/tomcat1

#!/bin/sh

# Startup Script for Tomcat6

# description: Tomcat Daemon

# processname: jsvc

# pidfile: /var/run/jsvc.pid

. /etc/rc.d/init.d/functions

export JAVA_HOME=/usr/local/jdk1.6.0_22

export CATALINA_HOME=//usr/local/tomcat1

DAEMON_HOME=$CATALINA_HOME/bin

TOMCAT_USER=tomcat

# for multi instances adapt those lines.

TMP_DIR=/var/tmp

PID_FILE=/var/run/jsvc.pid

CATALINA_BASE=$CATALINA_HOME

CATALINA_OPTS=

CLASSPATH=

$JAVA_HOME/lib/tools.jar:

$CATALINA_HOME/bin/commons-daemon.jar:

$CATALINA_HOME/bin/bootstrap.jar

case "$1" in

 start)

#

# Start Tomcat

#

$DAEMON_HOME/jsvc-src/jsvc

-user $TOMCAT_USER

-home $JAVA_HOME

-Dcatalina.home=$CATALINA_HOME

-Dcatalina.base=$CATALINA_BASE

-Djava.io.tmpdir=$TMP_DIR

-wait 10

-pidfile $PID_FILE

-outfile $CATALINA_HOME/logs/catalina.out

   -errfile '&1'

$CATALINA_OPTS

-cp $CLASSPATH

org.apache.catalina.startup.Bootstrap

#

# To get a verbose JVM

#-verbose

# To get a debug of jsvc.

#-debug

exit $?

;;

 stop)

#

# Stop Tomcat

#

$DAEMON_HOME/jsvc-src/jsvc

-stop

-pidfile $PID_FILE

org.apache.catalina.startup.Bootstrap

exit $?

;;

 *)

echo "Usage tomcat.sh start/stop"

exit 1;;

esac

chmod a+x /etc/init.d/tomcat1

9、启动|关闭

su - tomcat

/etc/init.d/tomcat1 start|stop

三、安装第二个tomcat

cp –r /usr/local/tomcat1 /usr/local/tomcat2

cp /etc/init.d/tomcat1 /etc/init.d/tomcat2

vi server.xml（修改如下内容）

connectionTimeout="20000"

redirectPort="9443"

URIEncoding="UTF-8" />

vi /etc/init.d/tomcat2（修改如下内容）

export CATALINA_HOME=//usr/local/tomcat2

启动|关闭

su - tomcat

/etc/init.d/tomcat2 start|stop

四、配置调度器nginx

vi nginx.conf（增加以下内容）

   upstream tomcatserver {

server 127.0.0.1:8080 srun_id=a weight=5 max_fails=2 fail_timeout=600s;

server 127.0.0.1:8180 srun_id=b weight=5 max_fails=2 fail_timeout=600s;

jvm_route $cookie_JSESSIONID|sessionid reverse;

   }

server {

   listen 80;

   server_name your domain;

   location / {

root /webroot;

index index.jsp index.do index.html index.htm;

rewrite "^/([0-9]+).html$" /a.jsp?id=$1 last;

   }

   location ~ ^/WEB-INF/* {

deny all;

   }

   location ~ .*.(jsp|do)?$ {

proxy_pass http://tomcatserver;

include proxy.conf;

   }

   log_format mainlogs '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

   access_log /var/log/nginx/oa.log mainlogs;

   location ~ /..+ {

deny all;

   }

}

重启nginx

/usr/local/nginx/sbin/nginx -t

/etc/init.d/nginx reload
