在CentOS下，要实现Tomcat的开机启动，已有能做的工具包括：

1. tomcat 自带的 jsvc， 这个工具会启动2个线程，如果应用对资源独占，会造成应用启动不了,这个和Apache Commons 里的 daemon 项目是一样的。

2. Java Service Wrapper ,

参考nginx的脚本，自己写了一个脚本，供大家参考：

# #!/bin/bash # # chkconfig: - 91 35 # description: Starts and stops tomcat CATALINA_HOME=/data/site/tomcat-8085 PID_FILE=/var/run/tomcat8085.pid JAVA_HOME=/usr/java/default JAVA_OPTS="-server -Xms512m -Xmx1024m" CATALINA_BASE=$CATALINA_HOME CATALINA_OPTS="-Djava.library.path=$CATALINA_HOME/bin" CLASSPATH=\ $JAVA_HOME/lib/tools.jar:\ $CATALINA_HOME/bin/commons-daemon.jar:\ $CATALINA_HOME/bin/bootstrap.jar RETVAL=0 # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 # Start daemons functions. start() { # # Start Tomcat # if [ -e $PID_FILE ];then echo "$PID_FILE already running...." exit 1 fi echo -n $"Starting $PID_FILE: " nohup $JAVA_HOME/bin/java \ -Dcatalina.home=$CATALINA_HOME \ -Dcatalina.base=$CATALINA_BASE \ -Djava.io.tmpdir=$TMP_DIR \ $CATALINA_OPTS \ -cp $CLASSPATH \ $JAVA_OPTS \ org.apache.catalina.startup.Bootstrap start >$CATALINA_HOME/logs/catalina.out & RETVAL=$? echo [ $RETVAL = 0 ] && touch $PID_FILE return $RETVAL } # Stop daemons functions. stop() { # # Stop Tomcat # echo -n $"Stopping $PID_FILE: " nohup $JAVA_HOME/bin/java \ -Dcatalina.home=$CATALINA_HOME \ -Dcatalina.base=$CATALINA_BASE \ -Djava.io.tmpdir=$TMP_DIR \ $CATALINA_OPTS \ -cp $CLASSPATH \ org.apache.catalina.startup.Bootstrap stop >$CATALINA_HOME/logs/catalina.out & RETVAL=$? echo [ $RETVAL = 0 ] && rm -f $PID_FILE return $RETVAL } # See how we were called. case "$1" in start) start ;; stop) stop ;; restart) stop start ;; *) echo $"Usage: $prog {start|stop|restart}" exit 1 esac exit $RETVAL  

安装步骤

1. #vi tomcatd 输入以上脚本

2. #chmod +x tomcatd 设置有执行权限

3. #cp tomcatd /etc/init.d 复制到启动目录

4. #chkconfig --add tomcatd

5. #chkconfig tomcatd on

6. #service tomcatd start 启动

7. #service tomcatd stop 停止
