Centos7 开机自启动脚本

做了java项目，jar包启动脚本已经写好了。想让他开机自启，做下记录：

1. 要自启的脚本

脚本位置任意，就叫 app_all_start.sh吧。暂放root目录下吧。脚本要有权限哦。

#!/bin/bash
#chkconfig: 35 20 80
#description: jar start

export JAVA_HOME=/usr/local/jdk1.8.0_381
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

echo "--------wait for mysql、redis、nacos--------------"
sleep 180s

## 多个jar包都要启动
/opt/workspace/test1/start.sh
sleep 20s
/opt/workspace/test2/start.sh
sleep 20s
/opt/workspace/test3/start.sh
sleep 20s
/opt/workspace/test4/start.sh

2. 单个jar 包 启动文件

就是上面那个start.sh文件

#!/bin/bash

export JAVA_HOME=/usr/local/jdk1.8.0_381
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

nohup java -jar -Xmx2g -Xms2g  -Dfile.encoding=utf-8 -Dspring.config.location=classpath:/application-test.yml /opt/workspace/test1/test1.jar >/dev/null 2>&1 &

3. app_all_start.sh自启

• 修改rc.local文件

vim  /etc/rc.d/rc.local

在最后添加自启的脚本

#!/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
 
/root/app_all_start.sh

• 给rc.local添加执行权限

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

• 重启服务器测试
