nginx-tomcat整合实现JAVA程序负载均

本组合使用软件各个版本：

Centos 5 Nginx-0.7.60-linux.tar.gz

tomcat5.5.27 for linux.zip jdk1_5_0_09-linux.bin pcre-7.8.tar.gz

操作系统安装不再详细说明，网上相关文档一大堆。

一.软件安装：

安装 JDK

将 jdk1_5_0_09-linux.bin 文件 cp 到/usr/local 目录下

添加权限：chmod u+x jdk1_5_0_09-linux.bin

执行安装：./ jdk1_5_0_09-linux.bin 按照提示输入 yes 即可完成安装

安装完成后会在/usr/local 下有个名为 jdk1.5.0_09 的目录

由于我做负载均衡，所以安装了两个 tomcat，解压 tomcat 到/usr/local/tomcat1 和/usr/local/tomcat2

分别进入/usr/local/tomcat1/bin 和/usr/local/tomcat2/bin 目录执行命令：chmod u+x *.Sh 设置权限

Tomcat1 保持不变，修改 tomcat2 下 conf 中 server.xml

<Server port="8005" shutdown="SHUTDOWN">
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

将红色字体的端口更改成其他不使用的端口，例如：8005 更改为 9005，8080 更改为 8081，8009 更改为 9009

修改 tomcat2 下 bin 中的 startup.sh 和 shutdown.sh 添加以下内容

export JAVA_HOME=/usr/local/java1.5.0_09
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=$JAVA_HOME/lib
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE

vi /etc/profile 配置系统变量，打开后添加以下内容：

JAVA_HOME=/usr/local/java1.5.0_09
export JAVA_HOME
CATALINA_BASE=/usr/local/tomcat1
CATALINA_HOME=/usr/local/tomcat1
export CATALINA_BASE CATALINA_HOME
TOMCAT_HOME=/usr/local/tomcat1
export TOMCAT_HOMECATALINA_2_BASE=/usr/local/tomcat2
CATALINA_2_HOME=/usr/local/tomcat2
export CATALINA_2_BASE CATALINA_2_HOME
TOMCAT_2_HOME=/usr/local/tomcat2
export TOMCAT_2_HOME
JRE_HOME=/usr/local/java1.5.0_09/jre
export JRE_HOME
CLASSPATH=/usr/local/java1.5.0_09/lib: /usr/local/java1.5.0_09/jre/lib
export CLASSPATH
PATH=$PATH:/usr/local/java1.5.0_09/bin:/usr/local/java1.5.0_09/jre/bin:/usr/local/tomcat1/bin:/usr/local/tomcat2/
bin
export PATH

保存退出，logout 注销一下

测试 JDK 是否安装成功

Java –version

看是否显示为刚刚安装的 jdk 版本名称

分别进入/usr/local/tomcat1/bin 和/usr/local/tomcat2/bin 目录执行./startup.sh

访问 http://local:8080/和 http://localhost:8081/看是否可以看到 tomcat 的欢迎界面

设置 tomcat 随系统启动

vi /etc/rc.d/rc.local 添加以下内容

/usr/local/tomcat1/bin/startup.sh

/usr/local/tomcat2/bin/startup.sh

安装 nginx，在安装 nginx 之前需要先安装所需的 pcre 库

解压我们下载的 pcre-7.8.tar.gz

tar zxvf pcre-7.8.tar.gz

cd pcre-7.8

./configure

make

make install

安装完毕

解压 nginx-0.7.60-linux.tar.gz

tar zxvf nginx-0.7.60-linux.tar.gz

./configure--user=www--group=www--prefix=/usr/local/nginx--with-http_stub_status_module--with-http_ssl_mod

ule

创建代理文件 vi /usr/local/nginx/conf/proxy.conf 输入以下内容proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 10m;

client_body_buffer_size 128k;

proxy_connect_timeout 600;

proxy_read_timeout 600;

proxy_send_timeout 600;

proxy_buffer_size 8k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

保存退出。

编辑 nginx.conf 文件 vi /usr/local/nginx/conf/nginx.conf 修改如下

#运行用户
#user nobody;
#启用进程
worker_processes 2;
#全局错误日志和 pid
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#工作模式及连接数上限

worker_connections 51200;
}

#配置 http 已经反向代理做负载均衡
