设置apache和nginx的tomcat负载平衡

概述

本篇文章主要先容apache和nginx的相关设置，tomcat的相关安装设置我在前面有写过一篇，具体先容通过两种设置要领设置nginx。

apache设置

源码安装

./configure--prefix=/usr/local/apache（安装目次）makemakeinstall

对付2.4以上版本的apache在举办源码安装的时候有的呆板会提示缺少部门插件譬喻：apr、apr-util、pcre，需要先将这些插件安装好然后再安装apache

YUM安装

yuminstallhttpd

设置tomcate负载平衡

进入安装目次cnf.d文件夹下面，建设一个.conf后缀的文件

touchapa.confvimapa.cnfListen8051ServerAdmin[email protected]ServerNamelocalhostErrorLog'/etc/httpd/logs/app_error.log'CustomLog'/etc/httpd/logs/app_access.log'commonProxyPass/balancer://cluster/stickysession=JSESSIONID|jsessionidnofailover=Onlbmethod=byrequeststimeout=5maxattempts=3ProxyPassReverse/balancer://cluster/ProxyRequestsOffProxyPreserveHostOn#BalancerMemberajp://localhost:8009route=tomcat_aBalancerMemberhttp://localhost:8080/Front#BalancerMemberajp://localhost:8010route=tomcat_bBalancerMemberhttp://localhost:8081/Front

设置文件一开始设置了apache的端口8051，然后在最下面设置了毗连tomcat的项目端口，我这里的设置的apache和tomcat都在一台处事器上面别离利用了差异的端口，在tomcat的webapps路径下面建设了一个Front项目，项目下面存放了一个test.jsp的测试页面

cd/usr/local/tomcat1/webappsmkdirFrontcdFronttouchtest.jspvimtest.jsptesta

同样在tomcat2中也利用同样的要领建设测试页面，可是将testa改成testb

接下来确保8051端口被启用，也可以封锁防火墙，tomcat1、tomcat2都已启动，启动要领参考前面我写的关于tomcat的文章，确保httpd也以启动，假如已经将httpd插手了启动处事，

启动http处事servicehttpdstart查察处事启动状态servicehttpdstatus

接下来在欣赏器中输入：http://localhost:8051/test.jsp

假如刷新毗连页面功效是在testa和testb之间切换，说明设置乐成。

nginx设置

源码安装

建设nginx用户组groupaddnginx建设nginx用户useradd-gnginx-s/sbin/nologinnginx安装相关插件yuminstall–ymakezlib-developenssl-develpcre-devel解压nginx安装包tarzxvfnginx-1.8.0.tar.gz进入安装包cdnginx-1.8.0安装./configure--prefix=/usr/local/nginx--with-http_ssl_module--with-http_gzip_static_module--with-http_stub_status_modulemake&&makeinstall

单个文件设置要领

建设测试页面

cd/usr/local/tomcat1/webappsmkdirMFrontcdMFronttouchindex.jspvimindex.jspMFronttesta

tomcat2也同样操纵，将MFronttesta改成MFronttestb

设置文件
