由於目前專案併發量大，需優化伺服器效能，本文使用Apache的負載均衡做配置，使靜態檔案由Apache處理，動態頁面由Tomcat處理。本文中以xx.demo.com域名為案例。

準備前：
一、./etc/httpd/httpd.conf中先開啟訪問日誌，便於監控，可以在全域性配置裡開啟，也可單獨配置單個專案/etc/httpd/extra/httpd-vhosts.conf
單個專案配置：

#xx.demo.com
<VirtualHost *:80>
   ServerAdmin [email protected]
    DocumentRoot "/web/app/demo"
    ServerName xx.demo.net
    ErrorLog logs/xx.demo.com-error_log
    TransferLog logs/xx.demo.com-access_log
    ErrorDocument 404 404.html
<Directory "/web/app/demo/">
        Options FollowSymLinks MultiViews
        AllowOverride None
        Order deny,allow
        Allow from all
</Directory>
JkMount / tomcat1
JkMount /* tomcat1
</VirtualHost>
 

二、開啟Tomcat訪問日誌

配置：tomcat/conf/server.xml

<Host name="xx.demo.com"  appBase="/web/app/demo" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
</Host>
 

開始配置：

三、在apache目錄/apach_2_2_9/conf下建立tomcat1_uriworkermap.properties檔案，配置如下：

/*=tomcat1
!/*.jpg=tomcat1
!/*.gif=tomcat1
!/*.png=tomcat1
!/*.bmp=tomcat1
!/*.html=tomcat1
!/*.htm=tomcat1
!/*.swf=tomcat1
!/*.css=tomcat1
!/*.js=tomcat1
 

#xx.demo.com
<VirtualHost *:80>
   ServerAdmin [email protected]
    DocumentRoot "/web/app/demo"
    ServerName xx.demo.net
    ErrorLog logs/xx.demo.com-error_log
    TransferLog logs/xx.demo.com-access_log
    ErrorDocument 404 404.html
<Directory "/web/app/demo/">
        Options FollowSymLinks MultiViews
        AllowOverride None
        Order deny,allow
        Allow from all
</Directory>
Alias / /web/app/demo/ROOT/
JkMountFile conf/tomcat1_uriworkermap.properties
</VirtualHost>
