apache2.4+tomcat8.0 cluster installation

The following installation method is for Windows platform

One, download apache2.4 and tomcat8.0 installation package

• Apache2.4:http://www.apachelounge.com/download/ (Windows platform may need to be installed : Visual C + + Redistributable For Visual Studio RC)

• Tomcat:http://tomcat.apache.org/download-80.cgi

Second, test start (extract an Apache and two tomcat)

Whether Apache and Tomcat were successfully launched separately. Apache's conf/httpd.conf needs to be configured as follows:

1. Modify the root path of ServerRoot Apache

2, open servername, as follows

3, modify the DocumentRoot

4, modify the Portal file configuration: DirectoryIndex (can be modified, not modified)

5, set the Serverscript directory

After Apache starts successfully, enter http://localhost in the browser address bar after the following page:

tomcat8.0 requires JDK7.0 or more support, each Tomcat Start.bat needs to be set to Java_home, CLASSPATH, Catalina_home (the current Tomcat Catalina_home). You can directly modify Start.bat as follows:

Third, change the Apache configuration

1. (Apache conf/httpd.conf) Modify httpd.conf Add module

#---------------------LoadModule start------------------------LoadModule lbmethod_byrequests_module modules/mod_ Lbmethod_byrequests.soloadmodule proxy_module modules/mod_proxy.soloadmodule proxy_ajp_module modules/mod_proxy_ Ajp.soloadmodule rewrite_module modules/mod_rewrite.soloadmodule proxy_balancer_module modules/mod_proxy_ Balancer.soloadmodule proxy_connect_module modules/mod_proxy_connect.soloadmodule proxy_ftp_module modules/mod_ Proxy_ftp.soloadmodule proxy_http_module modules/mod_proxy_http.soloadmodule slotmem_shm_module modules/mod_ Slotmem_shm.soloadmodule speling_module modules/mod_speling.soloadmodule ssl_module modules/mod_ssl.so#----------- -----------LoadModule End-------------------------

2. Remove the comment tag for include conf/extra/httpd-vhosts.conf #

3. Add reverse proxy at the end of file

Proxyrequests Off <proxy balancer://cluster>      balancermember ajp://127.0.0.1:8009 loadfactor=1 route=jvm1      balancermember ajp://127.0.0.1:9009 loadfactor=1 route=jvm2 </proxy>

4, modify the conf/extra/httpd-vhosts.conf

Comment out all the dummy-host, add the following content

<virtualhost *:80>          ServerAdmin [email protected]         ServerName localhost          serveralias localhost          Proxypass/balancer://cluster/stickysession=jsessionid Nofailover=on          proxypassreverse/balancer://cluster/          errorlog "Logs/lbtest-error.log"          Customlog "Logs/lbtest-access.log" Common </VirtualHost>

Four, change the Tomcat configuration: tomcat1 use 8080, tomcat2 use 9080

1, change tomcat2:<server port= "8005" shutdown= "Shutdown" > modified to 9005

2, modify <connector port= "8080" protocol= "http/1.1"
connectiontimeout= "20000"
redirectport= port in "8443"/> is 9080

3, modify <connector port= "8009" protocol= "ajp/1.3" redirectport= "8443"/> Modified to 9009

4, modify <engine name= "Catalina" defaulthost= "localhost" > at the end add jvmroute= "jvm2". At the same time, modify the TOMCAT1 label as Jvmroute= "JVM1" (the label is not open by default)

TOMCAT1:

TOMCAT2:

5, modify the TOMCAT1, Tomcat2 server.xml <cluster classname= "Org.apache.catalina.ha.tcp.SimpleTcpCluster"/> Changed to

<cluster classname= "Org.apache.catalina.ha.tcp.SimpleTcpCluster" >        <valve classname= " Org.apache.catalina.ha.tcp.ReplicationValve "filter=". *\.gif;. *\.js;. *\.jpg;. *\.png;. *\.htm;. *\.html;. *\.css;. *\.txt; " /></cluster>

6. Deploy test project to TOMCAT1 and TOMCAT2 below, then start TOMCAT1, TOMCAT2, Apache respectively. Then enter http://localhost/test/test.jsp in the Address bar to test.

Test item: http://download.csdn.net/detail/wuxian90/8847303

Note:

Apache may have some errors when booting up, common errors listed below (after correcting the error, you need to clear the log under logs, reboot)

• ah01177:failed to Lookup provider ' SHM ' for ' slotmem ': Is Mod_slotmem_shm loaded. let go mod_slotmem_shm .
• Ah02432:cannot Find LB method:byrequests. let go lbmethod_byrequests_module .
• ah00098:pid File E: / Java / Servers / 03_cluster / 00-apache24 /logs/httpd.pid overwritten--unclean shutdown of previous Apache run. Delete the file under logs/.
