jdk是下的rpm的安装，会默认安装倒到 /usr/java/下 （rpm 命令？查去）
tomcat 去官方下个压缩包，解压，手动考到了 /usr/下；修改 /etc/profile 文件，在其末尾加入一下内容：
引用:JAVA_HOME=/usr/local/jdk
MYSQL_HOME=/usr/local/mysql
CATALINA_BASE=/usr/local/jakarta-tomcat-5.0.30
CATALINA_HOME=/usr/local/jakarta-tomcat-5.0.30
TOMCAT_HOME=/usr/local/jakarta-tomcat-5.0.30
PATH=$PATH:$JAVA_HOME/bin:$MYSQL_HOME/bin
CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/j2ee.jar:$JAVA_HOME/lib/j2ee-svc.jar:$JAVA_HOME/lib:$JAVA_HOME/lib/htmlconverter.jar:$CATALINA_HOME/common/lib/servlet-api.jar:$JAVA_HOME/lib/servlet-api.jar:$CATALINA_HOME/common/lib/jsp-api.jar:$CATALINA_HOME/common/lib:$CATALINA_HOME/common/lib/mysql-connector-java-3.2.0-alpha-bin.jar:$CATALINA_HOME/common/lib:$JAVA_HOME/lib/mysql-connector-java-3.2.0-alpha-bin.jar:$CATALINA_HOME/common/lib/jotm.jar:$JAVA_HOME/lib/jotm_jrmp_stubs.jar:$JAVA_HOME/lib/connector-1_5.jar:$JAVA_HOME/lib/jta-spec1_0_1.jar:$JAVA_HOME/lib/xapool.jar:$JAVA_HOME/lib/xapool.jar:$JAVA_HOME/lib/howl.jar:$JAVA_HOME/lib/commons-cli-1.0.jar:.
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC JAVA_HOME CATALINA_HOME CLASSPATH MYSQL_HOME CATALINA_BASE TOMCAT_HOME JOTM_HOME ANT_HOME
ok了，可以启动 tomcat 和mysql 部署程序了
缀一句，执行/usr/apache-tomcat-5.5.25/bin / 下catalina.sh run 命令，可以看到tomcat的控制台信息。
