使用commons-daemon启动、关闭java程序
系统环境:
CentOS 7 X64
JDK1.8
一:
安装jsvc
下载 commons-daemon的源代码包
http://apache.fayea.com//commons/daemon/source/commons-daemon-1.0.15-src.zip
解压之后 cd src/native/unix/
运行:
export CFLAGS=-m64
export LDFLAGS=-m64
注意:这2句代码仅仅有64位系统才须要
./configure
make
完毕之后,就会在当前文件夹下生成jsvc文件,把它复制到一个文件夹下,这里是 /home/clouder/vs/jsvc 文件夹
然后,把JSVC_HOME增加到环境变量
vim .bashrc
export JSVC_HOME=/home/clouder/vs/jsvc
二:编写java代码
启动类必须实现Daemon接口,然后重写start(), stop()方法就可以
package com.lala; import org.apache.commons.daemon.Daemon; import org.apache.commons.daemon.DaemonContext; import org.apache.commons.daemon.DaemonInitException; public class Application implements Daemon { MyServer server = null; public void init(DaemonContext context) throws DaemonInitException,Exception { server = new MyServer(); } public void start() throws Exception { server.start(); } public void stop() throws Exception { server.stop(); } public void destroy() { System.exit(0); } }
<dependency> <groupId>commons-daemon</groupId> <artifactId>commons-daemon</artifactId> <version>1.0.15</version> </dependency>
三:编写shell脚本
server.sh
#!/bin/bash if [ "$JAVA_HOME" = "" ]; then echo "Error: JAVA_HOME is not set." exit 1 fi if [ "$JSVC_HOME" = "" ]; then echo "Error: JSVC_HOME is not set." exit 1 fi bin=`dirname "$0"` export MYJETTY_HOME=`cd $bin/../; pwd` MYJETTY_CONF_DIR=$MYJETTY_HOME/conf MYJETTY_WORK_DIR=$MYJETTY_HOME/work CLASSPATH="${MYJETTY_CONF_DIR}" for f in $MYJETTY_HOME/lib/*.jar; do CLASSPATH=${CLASSPATH}:$f; done LOG_DIR=${MYJETTY_HOME}/logs CLASS=com.lala.Application #jsvc所在的文件夹 DAEMON_HOME=$JSVC_HOME PID=${MYJETTY_WORK_DIR}/myjetty.pid case "$1" in start) $DAEMON_HOME/jsvc -Djava.io.tmpdir=$MYJETTY_WORK_DIR -wait 5000 -pidfile $PID -outfile LOG_DIR/myjetty.out -errfile '&1' -cp $CLASSPATH $CLASS exit $?;; stop) $DAEMON_HOME/jsvc -stop -pidfile $PID $CLASS exit $? ;; *) echo "Usage jsvc start,stop" exit 1;; esac
最后,使用
sh server.sh start启动服务
sh server.sh stop关闭服务
