linux计划任务crontab如何设定每分钟执行一次java程序

1.编辑一个脚本, 将java的环境变量写入其中,然后再加入程序运行语句到其中!例如,/root/bin/example.sh

2. #!/bin/bash
3. PATH=/usr/java/j2sdk1.4.2_06/bin:/usr/java/j2sdk1.4.2_06/jre/bin:$PATH
4. CLASSPATH=/usr/java/j2sdk1.4.2_06/lib:/usr/java/j2sdk1.4.2_06/jre/lib:/usr/java/j2sdk1.4.2_06/lib/tools.jar:/home/tomcat5/webapps/cms/WEB-INF/classes
5. export PATH CLASSPATH
6. java example

复制代码

2. #chmod u+x /root/bin/example.sh

复制代码

2.建立cron规则

2. #crontab -e

复制代码

2. * * * * *  /root/bin/example.sh

复制代码

1. 
   
2. #!/bin/bash
   
3. PATH=/home/oracle/j2sdk1.4.2_07/bin:/home/oracle/j2sdk1.4.2_07/jre/bin:$PATH
   
4. CLASSPATH=/home/oracle/j2sdk1.4.2_07/lib:/home/oracle/j2sdk1.4.2_07/jre/lib:/home/oracle/j2sdk1.4.2_07/lib/tools.jar:/usr/website/sichuan/webapps/ROOT/WEB-INF/classes;/home/oracle/tomcat/common/lib
   
5. export PATH CLASSPATH
   
6. java mms
   

复制代码

执行sh时提示错误:
bad interpreter: 没有那个文件或目录
是什么原因,如果解决?

1. 
   
2. [root@scutnet-linux6 oracle]# sh -x mms.sh
   
3. + PATH=/home/oracle:/home/oracle/j2sdk1.4.2_07/bin:/home/oracle/j2sdk1.4.2_07/jre/bin:/usr/kerberos/sbin:/home/oracle/j2sdk1.4.2_07/bin:/home/oracle/j2sdk1.4.2_07/jre/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/oracle/bin
   
4. + CLASSPATH=/home/oracle:/home/oracle/j2sdk1.4.2_07/lib:/home/oracle/j2sdk1.4.2_07/jre/lib:/home/oracle/j2sdk1.4.2_07/lib/tools.jar:.:/home/oracle/j2sdk1.4.2_07/lib:/home/oracle/j2sdk1.4.2_07/jre/lib:/usr/java/jdbc
   
5. + export PATH $'CLASSPATH\r'
   
6. ': not a valid identifierCLASSPATH
   
7. + java mms
   
8. Test mms at 2006-02-13 12:02:05

理解java class的定义！ 单独执行java class时候要写明位置！
比如/home/tomcat5/webapps/cms/WEB-INF/classes里有一个我要用的example.class 其放在/home/tomcat5/webapps/cms/WEB-INF/classes/Example/server/example.class.你在脚本里执行的时候就要写：

2. java Example.server.example

复制代码
