使用 /etc/rc.d/rc.local配置：

輸入命令：

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

這句話的意思是授予 /etc/rc.d/rc.local 檔案執行許可權

然後我們建立啟動檔案 runJar.sh

#!/bin/bash

export JAVA_HOME=/usr/local/jdk1.8.0_171
export JRE_HOME=/usr/local/jdk1.8.0_171/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH

cd /home/
nohup java -jar jcmes-center-0.0.1-SNAPSHOT.jar >center.log 2>&1 &
nohup java -jar jcmes-security-login-0.0.1-SNAPSHOT.jar >login.log 2>&1 &
nohup java -jar jcmes-card-0.0.1-SNAPSHOT.jar >card.log 2>&1 
 

這裡我們選擇是以生成log的方式啟動jar包。

啟動幾個jar 就在後邊新增，注意jdk的環境變數填寫正確

cd /home/ 的意思是 進入jar包目錄

接下來我們賦予runJar.sh 執行許可權

chmod +x /home/runJar.sh

最關鍵的步驟

執行命令 

vi /etc/rc.d/rc.local

編輯 rc.local檔案

#!/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
/home/runJar2.sh
 

注意最後一行 加入我們的啟動檔案

最後 重啟伺服器

[[email protected] ~]# reboot

我們看是否已經啟動

[[email protected] ~]# ps -ef | grep java
root        917      1 48 23:40 ?        00:00:11 java -jar jcmes-center-0.0.1-SNAPSHOT.jar
root        918      1 42 23:40 ?        00:00:09 java -jar jcmes-security-login-0.0.1-SNAPSHOT.jar
root       1091   1070  0 23:40 pts/0    00:00:00 grep --color=auto java
 

OK~!
