linux下同时起动两个tomcat都要做什么设置
我使用的是apache-tomcat-6.0.20的一个解压包。
修改了service.xml内的几个端口
tomcat1:
<Server port="6001" shutdown="SHUTDOWN">
<Connector port="8001" protocol="HTTP/1.1"
<Connector port="7001" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="tomcat1" defaultHost="localhost">

tomcat2:
<Server port="6002" shutdown="SHUTDOWN">
<Connector port="8002" protocol="HTTP/1.1"
<Connector port="7002" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="tomcat2" defaultHost="localhost">

还有catalina.sh文件内的
CATALINA_HOME
CATALINA_BASE
分别改为
CATALINA_HOME_1
CATALINA_HOME_2
CATALINA_BASE_1
CATALINA_BASE_2

环境变量为
export JAVA_HOME=/usr/local/jdk/jdk1.6.0_14
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export CATALINA_HOME_1=/usr/local/tomcat1
export CATALINA_HOME_2=/usr/local/tomcat2
export DAEMON_HOME_1=/usr/local/tomcat1/bin/jsvc-src
export DAEMON_HOME_2=/usr/local/tomcat2/bin/jsvc-src
export CATALINA_BASE_1=/usr/local/tomcat1
export CATALINA_BASE_2=/usr/local/tomcat2
export JRE_HOME=/usr/local/jdk/jdk1.6.0_14
export PATH=$JAVA_HOME/bin:$PATH

但还是会报异常
[WARN]main-org.apache.catalina.connector.MapperListener-Error registering contexts
java.lang.NullPointerException
