一個tomcat程序啓動多個tomcat實例

####環境

CATALINA_HOME /data/app/tomcat-7.0.64 tomcat程序所在目錄

CATALINA_BASE /data/app/tomcat-1 每一個tomcat實例配置文件，work，臨時文件的目錄 /data/app/tomcat-2

####多實例啓動準備

• 準備catalina_base並拷貝必要文件

# mkdir tomcat-1

# mdkir tomcat-2

# cp -a tomcat-7.0.64/{conf,logs,webapps,work,temp} tomcat-1/

# cp -a tomcat-7.0.64/{conf,logs,webapps,work,temp} tomcat-2/

• 修改配置文件，修改端口防止端口衝突

# cat tomcat-1/conf/server.xml

多實例啓動tomcat

# export CATALINA_HOME=/data/app/tomcat-7.0.64/

# export CATALINA_BASE=/data/app/tomcat-1/

# /data/app/tomcat-7.0.64/bin/startup.sh

Using CATALINA_BASE:   /data/app/tomcat-1/
Using CATALINA_HOME:   /data/app/tomcat-7.0.64/
Using CATALINA_TMPDIR: /data/app/tomcat-1//temp
Using JRE_HOME:        /data/app/jdk1.7.0_80
Using CLASSPATH:       /data/app/tomcat-7.0.64//bin/bootstrap.jar:/data/app/tomcat-7.0.64//bin/tomcat-juli.jar
Tomcat started.

# export CATALINA_BASE=/data/app/tomcat-2/

# /data/app/tomcat-7.0.64/bin/startup.sh

Using CATALINA_BASE:   /data/app/tomcat-2/
Using CATALINA_HOME:   /data/app/tomcat-7.0.64/

####不一樣實例參數的不一樣的解決

相同的參數能夠寫在$CATALINA_HOME/bin/catalina.sh裏，可是有些參數是得單獨寫的，好比jmx的端口 使用腳本啓動

• 啓動腳本
