2022.11.15 Centos7设置Jar包开机自启动

一、创建自启脚本 auto_start.sh

在 /etc/rc.d/init.d 目录下创建 auto_start.sh 文件

#!/bin/bash

#配置jdk的路径
export JAVA_HOME=/usr/jdk1.8.0_144
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

#项目1
export APP_NAME1="XXXX.jar"
export JVM_OPTS1="-Dname=${APP_NAME1}  -Duser.timezone=Asia/Shanghai -Xms512M -Xmx2g -XX:PermSize=256M -XX:MaxPermSize=2g -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"
#项目2
export APP_NAME2="XXXX.jar"
export JVM_OPTS2="-Dname=${APP_NAME2}  -Duser.timezone=Asia/Shanghai -Xms512M -Xmx2g -XX:PermSize=256M -XX:MaxPermSize=2g -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"

#静默启动
nohup java -jar  ${JVM_OPTS1} /usr/local/springboot/${APP_NAME1} > /dev/null 2>&1 &
nohup java -jar  ${JVM_OPTS2} /usr/local/springboot/${APP_NAME2} > /dev/null 2>&1 &

备注：

• XXXX.jar需替换为实际的jar包
• 若不清楚JDK位置，可用命令查询：

echo $JAVA_HOME

赋予执行权限

chmod +x /etc/rc.d/init.d/auto_start.sh

二、设置开机自启动

编辑/etc/rc.d目录下的rc.local文件

#!/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
#新增
/etc/rc.d/init.d/auto_start.sh

备注：

• 若需延迟启动，则可以加上 sleep

#延时5分钟
sleep 5m 
#执行
/etc/rc.d/init.d/auto_start.sh

赋予rc.local文件执行权限

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

三、重启服务器

重启命令：

reboot

查看包含.jar后缀的文件启动状态

ps -ef | grep .jar
