Ubuntu 20.04 安装 xxl-job 2.3.1 任务调度系统

配置过程需要全程链接外部网络

1.apt install net-tools                    #习惯问题
2.apt install ssh                            #方便远程安装操作
3.apt install vim -y                        #可以选择性安装
4.apt install maven                       #默认会安装 openjdk11  不需要单独配置jdk

更新源一下：

sudo apt-get update 

更新过程或显示缺失key  安装就行

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 467B942D3A79BD29

sudo apt-get update  

apt-cache policy mysql-server

安装 mysql 5.7   

#为什么不安装默认的 mysql 8.0  主要是 jdbc 的驱动问题。

sudo apt install mysql-community-client=5.7.41-1ubuntu18.04
sudo apt install mysql-client=5.7.41-1ubuntu18.04

sudo apt install mysql-community-server=5.7.41-1ubuntu18.04

这里输入 mysql root密码  123456     # 这里的密码需要和后面xxl-job 的密码统一

sudo apt install mysql-server=5.7.41-1ubuntu18.04

安装完毕检查，安装后的软件情况
dpkg -l | grep mysql

开始解压安装  xxl-job 
将压缩文件放到/opt 下
cd /opt

tar -zxvf xxl-job-2.3.1.tar.gz 

cd xxl-job-2.3.1/

vi xxl-job-admin/src/main/resources/application.properties

1.web端口，如果有冲突，一定要更换(本文采用默认8080)

server.port=8080

2.修改数据库信息

spring.datasource.url=jdbc:mysql://deptestxx:3306/xxl-job?Unicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=123456（修改成MySQL密码）

开始导入 xxl-job 数据库   导入的时候注意数据库文件的实际路径 

mysql -uroot -p123456 < /opt/xxl-job-2.3.1/doc/db/tables_xxl_job.sql

查看 mysql 数据导入情况   xxl-job 一共有8个表 确认是否完全正常

mysql -uroot -p123456

mysql> show databases;

mysql> use xxl_job

You can turn off this feature to get a quicker startup with -A

mysql> quit;

开始使用maven 打包   过程有点长 20-30分钟 左右

mvn package

启动  xxl-job

# 具体的 xxl-job-admin-2.3.1.jar  需要跟进自己的实际生成文件做调整

##########################开机自动启动脚本设置###########################################

开机自动启动脚本设置

由于ubuntu20.04LST 没有/etc/rc.local，需要创建一个.sh文件

sudo vi /etc/rc.local

脚本内容为

root@ibe-jobs:/etc/ssh# more /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

#source /etc/profile

nohup java -jar /opt/xxl-job-2.3.1/xxl-job-admin/target/xxl-job-admin-2.3.1.jar &
nohup java -jar /opt/xxl-job-2.3.1/xxl-job-executor-samples/xxl-job-executor-sample-springboot/target/xxl-job-executor-sample-springboot-2.3.1.jar &
exit 0

给脚本赋权限

sudo chmod +x /etc/rc.local

完成脚本编写后需要启动rc.local.service,命令如下

sudo vi /lib/systemd/system/rc-local.service

rc.local.service的内容如下

在文件下面添加如下内容,并且修改ExecStart

[Service]
ExecStart=/etc/rc.local start
[Install]
WantedBy=multi-user.target

执行

systemctl enable rc-local
systemctl start rc-local.service  #启动服务
systemctl status rc-local.service #查看状态
