部署spring cloud项目开机自启脚本的时候遇到了报错

5月 31 10:27:20 localhost.noob systemd[1]: Failed to start springcloud - resource recovery service.

2. 解决方案

2.1 新建 启动/停止/重启服务的shell文件

2.1.1 启动 recovery-start

#!/bin/bash
javaOptions="-Dfile.encoding=utf-8 -Xms512m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m"

nohup java $javaOptions -jar /recovery/ruoyi-gateway.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-auth.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-system.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-gen.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-file.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-recovery.jar >/dev/null 2>&1 & 

2.1.2 停止 recovery-stop

#!/bin/bash

ps -ef | grep ruoyi | grep -v grep | cut -c 10-16 | xargs kill -9

2.1.3 重启 recovery-restart

#!/bin/bash
javaOptions="-Dfile.encoding=utf-8 -Xms512m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m"

ps -ef | grep ruoyi | grep -v grep | cut -c 10-16 | xargs kill -9

nohup java $javaOptions -jar /recovery/ruoyi-gateway.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-auth.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-system.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-gen.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-file.jar >/dev/null 2>&1 & 
nohup java $javaOptions -jar /recovery/ruoyi-modules-recovery.jar >/dev/null 2>&1 & 

2.2 创建 recovery.service 服务启动项

2.2.1 新建 recovery.service 服务文件

systemd有系统和用户区分

系统（/usr/lib/systemd/system/）

用户（/etc/lib/systemd/user/）

一般系统管理员手工创建的单元文件建议存放在/etc/systemd/system/目录下面。

vim /lib/systemd/system/recovery.service

[Unit]
Description=springcloud - resource recovery service
Documentation=https://qwq.ro
After=network.target
[Service]
Type=forking
ExecStart=/bin/bash /recovery/bin/recovery-start
ExecReload=/bin/bash /recovery/bin/recovery-restart
ExecStop=/bin/bash /recovery/bin/recovery-stop
PrivateTmp=true
[Install]
WantedBy=multi-user.target

3. 测试

systemctl daemon-reload # 先进行文件生效配置 systemctl enable recovery.service # 设置为开机启动 systemctl start recovery.service # 启动nacos服务 systemctl stop recovery.service # 停止nacos服务
