nginx-tomcat整合实现java程序负载均衡

1、linux+nginx+tomcat+jdk整合实现java程序负载均衡木组合使川软件各个版木：centos 5 nginx-0.7.60-linux.tar.gz tomcat5.5.27 for linux.zip jdkl_5_0_09-iinux.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 jdkl_5_0_09-linux.bin 文件 cp 到/usr/local 目录卜添加权限：chmod u+x jdkl_5_0_09-linux.bin执行安装：./jdkl_5_0_09-linux.bin按照提示输入yes即

2、可完成安装安装完成后会右"usr/local下有个名为jdkl.5.0_09的目录山于我做负载均衡，所以安装了两个tomcat,解丿卞：【omca【至i/usr/k)cal/omca( 1和/usr/local/tomcat2分别进入/usr/local/tomcat 1/bin fll/usr/local/tomcat2/bin 目录执行命令:chmod u+x *.sh 设置权限tomcatl 保持不变，修改 tomcat2 下 conf 中 server.xml<scrvcr port=h8005" shutdown="shutdown,><

3、;! define a non-ssl http/1.1 connector on port 8080 -><connector port="8080" maxhttpheadersize="8192"maxthreads=" 150" minspiirethreads="25" maxsparethreads="75"enablelookups="false" redirectport="8443" acceptcount=" 10

4、0"conncctiontimcout="20000" disableuploadtimeout=,true" /><! define an ajp 1.3 connector on port 8009 -><connector port="8009" enablelookups="false" redirectport="8443m 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9(x)5, 8080更

5、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/javal .5.0_09export path=spath:$java_home/binexport classpath=sjava_home/libexport catalina_home=$catalina_2_homeexport catalina_base=$catalina_2_basevi /etc/profile配置系统变量，打开后添加以下内容：java_home=/usr/local/java

6、l .5.0_09export java_homecatalina_base=/usr/local/tomcatlcatalina_home=/usr/local/tomcatlexport catalina.base catalina.hometomcat_home=/usr/)ocal/tomcatlexport tomcat_homecatalin a_2_base=/usr/local/tomcat2catalin a_2_home=/usr/local/tomcat2export catalina_2_base catal1na_2_hometomcat_2_home=/usr/lo

7、cal/tomcat2export tomcat_2_homejre_home=/usr/local/javal.5.0_09/jreexport jre.homeclasspath=/usr/local/java 1.5.0_09/lib: /usr/local/javal .5.0_09/jre/libexport classpathpath=$path:/usr/local/javal.5.0_09/bin:/usr/local/javal.5.0_09/jre/bin:/usr/local/tomcatl/bin:/usr/local/tomcat2/binexport path保存退

8、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版木名称分别进入/usr/local/tomcat 1 /bin 和/usr/local/tomcat2/bin | 求执fj/startup.sh访问 httd：/local:8080/和 httd：/localhost:8081/看是否可以看到 tomcat 的欢迎界血设置tomcat随系统启动vi /etc/rc.d/rc.local 添加以下内容/usr/local/tomcat 1/bin/startup.sh/usr/local/tomcat2/bin/startup.sh安装ngin

9、x,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.gztar zxvf pcre 78tagzcd pcrc-7.8./configuremakemake install安装完毕解压 nginx-0.7.60-linux.tar.gztar zxvf nginx-0.7.60-linux.ta r.gz./configure-user=www-group=www-prefix=/usr/local/nginx-with-h(tp_stub_status_module-with-http_ssl_module创建代理文件vi /usr/local/ngin

10、x/conf/proxy.conf输入以下内容proxy_redirect proxy_sct_hcadcr proxy_set_header proxy_set_headeoff;host$host;x-real-ip$remote_addr;x-forwarded-for sproxy_add_x_forwarded_for;client_max_body_size 10m; client_body_buffer_size 128k;proxy_connect_timeout 600; proxy_rcad_tinicout 600; proxy_send_timeout 600;prox

11、y_buffer_size 8k: proxy_buffers 4 32k;proxy_busy_buffers_size 64k; poxy_tcmp_filc_witc_sizc 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;#卅用进程worker_processes 2; #全局错误日志和pid crror_log logs/crror.log;#error_log logs/error.log notice;#error_log logs/error.log i
