一 需要启动的jar包

yt_transport_service_source-V1.0.21.jar
transport-task-1.0-SNAPSHOT.jar
transport-web-java-1.0-SNAPSHOT.jar
yt_transport_web_source-1.0.1.jar

二 编写脚本文件
该脚本文件的存放位置和名字都是任意的，此处起名为allstart.sh，存放位置为当前目录。

vim allstart.sh

在打开的文件中输入以下代码信息，保存并退出：

#!/bin/bash

export JAVA_HOME=/opt/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

nohup java -jar /usr/local/web/platform/transport_service_source_7098/yt_transport_service_source-V1.0.21.jar --server.port=7098 > /usr/local/web/platform/transport_service_source_7098/yt_transport_service_source.log 2>&1 &
nohup java -jar /usr/local/web/platform/transport_task_18070/transport-task-1.0-SNAPSHOT.jar --server.port=18070 > /usr/local/web/platform/transport_task_18070/transport-task.log 2>&1 &
nohup java -jar /usr/local/web/platform/transport_web_8060/transport-web-java-1.0-SNAPSHOT.jar --server.port=8060 > /usr/local/web/platform/transport_web_8060/transport-web.log 2>&1 &
nohup java -jar /usr/local/web/platform/transport_web_source_8088/yt_transport_web_source-1.0.1.jar --server.port=8088 > /usr/local/web/platform/transport_web_source_8088/yt_transport_web_source.log 2>&1 &

解释：

/usr/local/web/platform/transport_service_source_7098/yt_transport_service_source-V1.0.21.jar是jar包的绝对路径；

--server.port=7098是服务的端口号；

/usr/local/web/platform/transport_service_source_7098/yt_transport_service_source.log是日志的输出路径。

操作说明：

1.如果没有vim工具，可以下载一个，使用yum install vim命令即可下载；或者将vim命令改成vi也是可以的，vi是系统自带的编辑工具。

2.编辑文件，首先得按一下i键，进入编辑，编辑完之后按esc键退出编辑，最后按:wq保存并退出。

三 给allstart.sh添加执行权限

chmod +x allstart.sh

四 编辑rc.local文件

vim /etc/rc.d/rc.local

在rc.local文件末尾添加allstart.sh文件的路径，保存并退出：

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
/usr/local/web/platform/allstart.sh

五 授予rc.local文件执行权限

chmod +x /etc/rc.d/rc.local

六 重启

reboot

七 重启之后查看jar包是否启动

[root@localhost platform]# ps -ef | grep java
root 1572 1 0 10:59 ? 00:02:52 java -jar /usr/local/web/platform/transport_service_source_7098/yt_transport_service_source-V1.0.21.jar --server.port=7098
root 1574 1 0 10:59 ? 00:01:22 java -jar /usr/local/web/platform/transport_task_18070/transport-task-1.0-SNAPSHOT.jar --server.port=18070
root 1580 1 0 10:59 ? 00:03:08 java -jar /usr/local/web/platform/transport_web_source_8088/yt_transport_web_source-1.0.1.jar --server.port=8088
root 1609 1 0 10:59 ? 00:02:17 java -jar /usr/local/web/platform/transport_eureka_8000/spring-cloud-eureka.jar --server.port=8000
root 5404 4945 0 11:40 pts/0 00:02:01 java -jar /usr/local/web/platform/transport_web_8060/transport-web-java-1.0-SNAPSHOT.jar --server.port=8060
root 23572 21935 0 16:13 pts/1 00:00:00 grep --color=auto java

至此，jar包开机自动启动脚本编写完毕~

都看到这了，动动你的小手点个赞吧！
