Configuration of multiple Tomcat7 running on a single CentOS host

Environment:

CentOS 6.5 x64

JDK8

apache-tomcat-7.0.70

1. Plan and configure the port:

Tomcat	HTTP port, default 8080	AJP Port, default 8009	Remote Stop service port, default 8005
original apache-tomcat-7.0.70	71  <connector port= "8080 "  protocol= "http/1.1"                     connectiontimeout= "20000"                    redirectport= " 8443 "/>	< Connector port= "8009 "  protocol= "ajp/1.3" redirectport= "8443"/>	22  <server port= "8005 " shutdown=" shutdown ";
Tomcat7-com-80	<connector port= "protocol=" http/1.1 " connectiontimeout= "20000" Redirectport= "8443" uriencoding= "UTF-8"/>	<connector port= "8030" protocol= "ajp/1.3" redirectport= "8443"/>	<server port= "8006" shutdown= "Shutdown" >
tomcat7-ms-81	<connector port= "bayi" protocol= "http/1.1" connectiontimeout= "20000" Redirectport= "8443" uriencoding= "UTF-8"/>	<connector port= "8031" protocol= "ajp/1.3" redirectport= "8443"/>	<server port= "8007" shutdown= "Shutdown" >
tomcat7-app-3800	<connector port= "3800" protocol= "http/1.1" connectiontimeout= "20000" Redirectport= "8443" uriencoding= "UTF-8"/>	<connector port= "8032" protocol= "ajp/1.3" redirectport= "8443"/>	<server port= "8008" shutdown= "Shutdown" >

2. Download tomcat and unzip, empty the WebApps content, create a new root directory, and then modify the Server.xml content.

Under about 126 lines, add the app's configuration:

126 unpackwars= "true" autodeploy= "true" >

<context path= "" docbase= "ROOT" debug= "0" reloadable= "true" allowlinking= "true"/>

In this case, simply empty the WebApps directory, create a new root folder, and copy the app to the root folder.

3. Replication of three Tomcat servers

Cp-r apache-tomcat-7.0.70 tomcat7-com-80
Cp-r apache-tomcat-7.0.70 tomcat7-ms-81

Cp-r apache-tomcat-7.0.70 tomcat7-app-3800

4. Configure three Tomcat ports according to the plan.

5. Create a Tomcat environment settings script

Under Tomcat's Bin directory, create the setenv.sh file:

#add Tomcat PID Catalina_pid= "$CATALINA _base/tomcat-ms-81. PID" #add Java opts Java_opts= "-server-xx:permsize=1024m-xx:maxpermsize=1024m-xss1024k-xms512m-xmx1024m-xx:maxnewsize=512m"

Note Modify the red PID name, the above parameters mean the following:

-XMS JVM initializing heap memory size

-XMX maximum memory for JVM heap

-XSS Thread Stack size

-xx:permsize JVM Initial memory allocation size for non-heap areas

-xx:maxpermsize JVM non-heap maximum memory

6. Deploy the app and start Tomcat in turn, with the following script:

/usr/local/hmg/tomcat7-com-80/bin/shutdown.sh/usr/local/hmg/tomcat7-ms-81/bin/shutdown.sh/usr/local/hmg/ tomcat7-app-3800/bin/shutdown.sh/usr/local/hmg/tomcat7-com-80/bin/startup.sh/usr/local/hmg/tomcat7-ms-81/bin/ startup.sh/usr/local/hmg/tomcat7-app-3800/bin/startup.sh
