❸ linux下如何設置jetty開機啟動

在/etc/init.d/下創建jetty文件內容：

vim/etc/init.d/jetty
#內容如下：
#!/bin/bash
#chkconfig:35951
#description:scripttostart/stopjettycase$1instart)
sh/opt/startjetty.sh;;stop)
sh/opt/stopjetty.sh;;*)
echo"Usage:$0(start|stop)";;esac
#更改許可權
chmod775jetty
#加入自動啟動
chkconfig–addjetty
#查看自動啟動設置
chkconfig–listjetty
jetty0:off1:off2:off3:on4:off5:on6:off

以後可以用以下命令啟動和停止腳本

servicejettystart#啟動
servicejettystop#停止
