linux配置多個tomcat

 對於如今server的配置，內存4G，動輒幾十G內存，徹底能夠一機多tomcat徹底利用起來。一機多tomcat須要修改tomcat配置文件幾處地方。

1.tomcat環境變量
環境變量中自定義多tomcat主目錄
vi /etc/profile
 

export CATALINA_1_HOME=/usr/local/tomcat1
export TOMCAT_1_HOME=/usr/local/tomcat1
export CATALINA_2_HOME=/usr/local/tomcat2
export TOMCAT_2_HOME=/usr/local/tomcat2
export CATALINA_3_HOME=/usr/local/tomcat3
export TOMCAT_3_HOME=/usr/local/tomcat3

2.tomcat配置文件server.xml端口JVM虛擬機名稱

每一個tomcat的8005 8080 8009 8443端口不能同樣，好比：

tomcat1爲：

8005改成8501

8080改成8801

8009改成8901

8443改成8401

tomcat2爲:

8005改成8502

8080改成8802

8009改成8902

8443改成8402

tomcat3爲:

8005改成8503

8080改成8803

8009改成8903

8443改成8403

 

修改JVM名稱:

找到每一個tomcat的<Engine name="Catalina" defaultHost="localhost">配置分別修改成修改成(每一個tomcat的jvm名稱不能一致):

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat3">

 

 

3.修改tomcat啓動、中止腳本

vi /etc/init.d/tomcat1

#############################################
export JAVA_HOME=/usr/java/default
export CATALINA_HOME=$CATALINA_1_HOME

case "$1" in
  'start')
    /usr/local/tomcat1/bin/startup.sh
    touch /var/lock/subsys/tomcat1
    ;;

  'stop')
    /usr/local/tomcat1/bin/shutdown.sh
    rm -f /var/lock/subsys/tomcat1
    ;;

  'restart')
    $0 stop
    $0 start
    ;;

  *)
    echo "Usage: tomcat1 { start | stop | restart }"
    exit 1
esac
exit 0
###############################################

vi /etc/init.d/tomcat2

#############################################
export JAVA_HOME=/usr/java/default
export CATALINA_HOME=$CATALINA_2_HOME

case "$1" in
  'start')
    /usr/local/tomcat2/bin/startup.sh
    touch /var/lock/subsys/tomcat2
    ;;

  'stop')
    /usr/local/tomcat2/bin/shutdown.sh
    rm -f /var/lock/subsys/tomcat2
    ;;

  'restart')
    $0 stop
    $0 start
    ;;

  *)
    echo "Usage: tomcat2 { start | stop | restart }"
    exit 1
esac
exit 0
###############################################

vi /etc/init.d/tomcat3

#############################################
export JAVA_HOME=/usr/java/default
export CATALINA_HOME=$CATALINA_3_HOME

case "$1" in
  'start')
    /usr/local/tomcat3/bin/startup.sh
    touch /var/lock/subsys/tomcat3
    ;;

  'stop')
    /usr/local/tomcat3/bin/shutdown.sh
    rm -f /var/lock/subsys/tomcat3
    ;;

  'restart')
    $0 stop
    $0 start
    ;;

  *)
    echo "Usage: tomcat3 { start | stop | restart }"
    exit 1
esac
exit 0
###############################################

 

配置完成後須要給/etc/init.d/目錄中的tomcat1 tomcat2 tomcat3文件添加執行權限。

chmod u+x /etc/init.d/tomcat1
chmod u+x /etc/init.d/tomcat2
chmod u+x /etc/init.d/tomcat3

而後啓動tomcat使用如下命令就能夠啓動了：

service tomcat1 start
service tomcat2 start
service tomcat3 start

中止tomcat的命令與啓動命令基本相同，start改成tomcat就OK了。
