## 一、安装java 环境 ``` yum install java-1.8.0-openjdk ``` ## 二、安装mysql 环境 ### 2.1 安装Yum Repository ``` wget https://repo.mysql.com//mysql80-community-release-el8-1.noarch.rpm ``` ### 2.2 使用rpm来安装MySQL ``` rpm -ivh mysql80-community-release-el8-1.noarch.rpm ``` ### 2.3 使用yum安装mysql服务 ``` yum install mysql-server ``` ### 2.4 检查是否已经设置为开机启动MySQL服务 ``` [root@localhost ~]# systemctl list-unit-files|grep mysqld mysqld.service disabled mysqld@.service disabled [root@localhost ~]# systemctl enable mysqld.service #设置开机启动 Created symlink /etc/systemd/system/multi-user.target.wants/mysqld.service → /usr/lib/systemd/system/mysqld.service. [root@localhost ~]# systemctl list-unit-files|grep mysqld mysqld.service enabled mysqld@.service disabled [root@localhost ~]# ps -ef|grep mysql # 查看是否启动MySQL服务 root 4311 32702 0 21:07 pts/4 00:00:00 grep --color=auto mysql [root@localhost ~]# systemctl start mysqld.service #启动服务 ``` ### 2.5 修改root密码及开启远程连接 ``` # 第一步 本地登录mysql mysql -uroot -p # 第二步 切换数据库 use mysql # 第三步 创建用户 CREATE USER 'root'@'%' IDENTIFIED BY 'mysql密码'; # 第四步 授予所有权限 grant all privileges on *.* to 'root'@'%'; # 第五步 更新root@localhost的密码 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysql密码'; # 第六步 刷新权限 flush privileges; ``` ## 三、打包部署 ``` # 项目打包 mvn clean package -Dmaven.test.skip=true # 传输项目到指定服务器 # 运行jar nohup java -jar -Xms256m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m ruoyi-admin.jar > ruoyi-admin.log 2>1 & nohup java -jar -Xms256m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m ruoyi-api.jar >ruoyi-api.log 2>1 & ```
