tomcat单机多实例配置实战

更新：2022-05-23 13:44:51编辑：Story归类：nginx人气：226

java不同于php,单个站点更新维护都会影响到其他站点，一般都会将几个站点放在一个实例下。今天全称演示单台服务器如何配置多个tomcat实例。

环境

tomcat：/usr/local/tomcat-7.0.50
a.ttlsa.com
站点程序：/data/site/a.ttlsa.com
端口：8080

b.ttlsa.com
站点程序：/data/site/b.ttlsa.com
端口：8081

1. tomcat安装

安装很简单，配置好jdk与解压tomcat即可，关于《tomcat安装》我这边不再重复了。

如果连接失效，请复制http://www.ttlsa.com/web/install-tomcat7-on-linux/

2. 配置多实例目录

在tomcat安装目录下创建a.ttlsa.com、b.ttlsa.com，并且将conf、logs、webapp、temp、work目录拷贝到这两个目录，然后tomcat安装目录只需要留下bin、a.ttlsa.com、b.ttlsa.com、lib这4个目录即可。配置后的目录结构如下：

# pwd
 /usr/local/tomcat-7.0.50
 # tree -d -L 2
 ├── bin
 ├── a.ttlsa.com
 │ ├── conf
 │ ├── logs
 │ ├── target
 │ ├── temp
 │ ├── webapp
 │ └── work
 ├── lib
 └── b.ttlsa.com
 ├── conf
 ├── logs
 ├── temp
 ├── webapp
 └── work

# pwd

/ usr / local / tomcat - 7.0.50

# tree -d -L 2

├── bin

├── a . ttlsa . com

│ ├── conf

│ ├── logs

│ ├── target

│ ├── temp

│ ├── webapp

│ └── work

├── lib

└── b . ttlsa . com

├── conf

├── logs

├── temp

├── webapp

└── work

3. 配置站点server.xml

3.1 配置a.ttlsa.com

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml
//注释ajp
<!-- <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> -->

//server端口8005改为8001
<Server port="8001" shutdown="SHUTDOWN">

//在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下
<Host name="a.ttlsa.com" appBase="/data/site/a.ttlsa.com"
      unpackWARs="true" autoDeploy="true"
      xmlValidation="false" xmlNamespaceAware="false">
      <Context path="" docBase=""  reloadable="true">
        <valve className="org.apache.catalina.valves.RemoteAddrValve" />
      </Context>
</Host>

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml

//注释ajp

< ! -- < Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443" / > -- >

//server端口8005改为8001

< Server port = "8001" shutdown = "SHUTDOWN" >

//在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下

< Host name = "a.ttlsa.com" appBase = "/data/site/a.ttlsa.com"

unpackWARs = "true" autoDeploy = "true"

xmlValidation = "false" xmlNamespaceAware = "false" >

< Context path = "" docBase = "" reloadable = "true" >

< valve className = "org.apache.catalina.valves.RemoteAddrValve" / >

< / Context >

< / Host >

3.2 配置b.ttlsa.com

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml
//注释ajp
<!-- <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> -->

//server端口8005改为8002
<Server port="8002" shutdown="SHUTDOWN">

//在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下
<Host name="b.ttlsa.com" appBase="/data/site/b.ttlsa.com"
      unpackWARs="true" autoDeploy="true"
      xmlValidation="false" xmlNamespaceAware="false">
      <Context path="" docBase=""  reloadable="true">
        <valve className="org.apache.catalina.valves.RemoteAddrValve" />
      </Context>
</Host>

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml

//注释ajp

< ! -- < Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443" / > -- >

//server端口8005改为8002

< Server port = "8002" shutdown = "SHUTDOWN" >

//在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下

< Host name = "b.ttlsa.com" appBase = "/data/site/b.ttlsa.com"

unpackWARs = "true" autoDeploy = "true"

xmlValidation = "false" xmlNamespaceAware = "false" >

< Context path = "" docBase = "" reloadable = "true" >

< valve className = "org.apache.catalina.valves.RemoteAddrValve" / >

< / Context >

< / Host >

4. 多实例启动脚本

在a.ttlsa.com、b.ttlsa.com目录下分别创建启动脚本tomcat.sh
4.1 脚本内容tomcat.sh

#!/bin/sh
 # AuthName：凉白开
 # Website：http://www.ttlsa.com
 # DateTime：2014-05-04
 # description: 启动tomcat多实例.
 . /etc/init.d/functions
 RETVAL=$?
 # tomcat实例目录
 export CATALINA_BASE="$PWD"
 # tomcat安装目录
 export CATALINA_HOME="/usr/local/tomcat-7.0.50"
 # 可选
 export JVM_OPTIONS="-Xms128m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m"
 case "$1" in
 start)
 if [ -f $CATALINA_HOME/bin/startup.sh ];then
 echo $"Start Tomcat"
 $CATALINA_HOME/bin/startup.sh
 fi
 ;;
 stop)
 if [ -f $CATALINA_HOME/bin/shutdown.sh ];then
 echo $"Stop Tomcat"
 $CATALINA_HOME/bin/shutdown.sh
 fi
 ;;
 *)
 echo $"Usage: $0 {start|stop}"
 exit 1
 ;;
 esac
 exit $RETVAL

#!/bin/sh

# AuthName：凉白开

# Website：http://www.ttlsa.com

# DateTime：2014-05-04

# description: 启动tomcat多实例.

. / etc / init . d / functions

RETVAL = $ ?

# tomcat实例目录

export CATALINA_BASE = "$PWD"

# tomcat安装目录

export CATALINA_HOME = "/usr/local/tomcat-7.0.50"

# 可选

export JVM_OPTIONS = "-Xms128m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m"

case "$1" in

start )

if [ - f $ CATALINA_HOME / bin / startup . sh ] ; then

echo $ "Start Tomcat"

$ CATALINA_HOME / bin / startup . sh

; ;

stop )

if [ - f $ CATALINA_HOME / bin / shutdown . sh ] ; then

echo $ "Stop Tomcat"

$ CATALINA_HOME / bin / shutdown . sh

; ;

* )

echo $ "Usage: $0 {start|stop}"

exit 1

; ;

esac

exit $ RETVAL

4.2 启动脚本赋权限

# chmod a+x tomcat.sh

1	# chmod a+x tomcat.sh

5. 启动测试

5.1 启动/关闭a.ttlsa.com

启动
 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/
 # ./tomcat.sh start
 关闭
 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/
 # ./tomcat.sh stop

启动

# cd /usr/local/tomcat-7.0.50/a.ttlsa.com/

# ./tomcat.sh start

关闭

# cd /usr/local/tomcat-7.0.50/a.ttlsa.com/

# ./tomcat.sh stop

5.2 启动/关闭b.ttlsa.com

启动
 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/
 # ./tomcat.sh start
 关闭
 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/
 # ./tomcat.sh stop

启动

# cd /usr/local/tomcat-7.0.50/a.ttlsa.com/

# ./tomcat.sh start

关闭

# cd /usr/local/tomcat-7.0.50/a.ttlsa.com/

# ./tomcat.sh stop

备注：一定需要cd到tomcat.sh的当前目录下执行才可以

6. 结束

配置到此结束，如果需要操作多个实例显得比较麻烦，大家可以自行写统一的脚本，我这边有自己的一份，有需要的可以找我要。内容比较多，就不贴出来了。
