(OCPP服务器)SteVe编译搭建全过程

注意：建议使用3.6.0，我升级到3.7.1，并没有多什么新功能，反而电表的实时数据只能看到累计电能了，我回退了就正常，数据库是兼容的，java版本换位java11，其他不变就好

背景：
国外欧标充电桩开发中，服务器对接是很重要的一环，出国外的基本都是需要支持OCPP功能，基本要求是OCPP1.6，还有些客户已经开始要2.0了，OCPP测试至关重要，目前有两种测试方法，1，使用Monta服务器，去注册一个账号，然后链接调试即可，2.自己在云端搭建一个自己的OCPP平台（SteVe）。
两个平台我都有使用，用得多并且顺手的是SteVe平台。以下是简单总结一下使用后的感受。
Monta平台界面比较单一，下发的命令的应答只能看log里面找到对应的应答数据（json），优点是有认证测试功能，可以免费自己注册一个账号就能使用，免费https://ocpp-toolkit.monta.app/

SteVe平台界面丰富，可以管理ocpp tags（充电卡）或者get configration的时候预设很多系统的key使用，应答命令会帮你解析在页面显示出来，目前SteVe平台是最完善的，并且是开源免费的。

综上所述，自己搭建一个服务器就很有必要了。

SteVe平台搭建主要流程：

• 1.先准备一个云服务器，如果没有云服务器，可以考虑用虚拟机安装一个centos7，然后把这个机器映射到外网临时用也行。
• 2.下载SteVe官方源码包，我这里就用3.17.1举例。官方源码在GitHub https://github.com/steve-community/steve。
• 3.数据库MYSQL8的安装与配置，因为CentOS使用的是mariadb，但你去编译SteVe的时候你会发现提示非长期支持版，会报错。
• 4.安装Java17，Centos内置了Java工具，但查看版本发现是1.8的，SteVe3.7.1要求是Java17，删除Java1.8再安装Java17.
• 5.编译SteVe源码。
• 6.运行，测试
• 7.制作开机自启。

详细步骤：
1.下载SteVe源码。并阅读README.md，了解这个平台需要用到的环境，先配置好这些环境，然后了解编译工具和编译运行。经过阅读发现需要使用mysql8，java17，Maven
2.首先来安装数据库，数据库MYSQL8的安装与配置，查看当前mariadb版本信息。

rpm -e --nodeps 上一条命令列出的文件名。
rpm -qa|grep mariadb 用于检查是否卸载干净。

让AI帮忙写了一个centos7安装mysql8的脚步，这样比传统的下载安装更省事

#!/bin/bash# Exit script on any error
set -e# Fixed password to be used
fixed_password="Msb666666"# 1. Add the MySQL Yum repository
echo "Adding the MySQL Yum repository..."
wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpmecho "Checking the integrity of the downloaded package..."
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysqlecho "Installing the MySQL Yum repository..."
yum localinstall mysql80-community-release-el7-3.noarch.rpm -y# 2. Install the MySQL server
echo "Installing the MySQL server..."
yum install mysql-community-server -y# 3. Start the MySQL service
echo "Starting the MySQL service..."
systemctl start mysqld
systemctl enable mysqld# 4. Get the temporary password generated for the root user
echo "Retrieving the temporary password..."
temp_password=$(grep 'temporary password' /var/log/mysqld.log | tail -1 | rev | cut -d" " -f1 | rev)echo "The temporary MySQL root password is: $temp_password"# 5. Change the root user's password to the desired fixed password
echo "Changing the root user's password..."mysql --connect-expired-password -uroot -p"$temp_password" <<-EOF
ALTER USER 'root'@'localhost' IDENTIFIED BY '$fixed_password';
FLUSH PRIVILEGES;
EOFecho "The root password has been successfully changed to the fixed password."# Optionally, you can run the mysql_secure_installation steps here if you want to automate it further.echo "MySQL 8 installation is complete."

还有mysql运行脚本

#!/bin/bash# This script starts the MySQL service and sets it to launch on boot# Exit script on any error
set -e# Start the MySQL service
echo "Starting the MySQL service..."
systemctl start mysqld# Enable the MySQL service to start on boot
echo "Setting the MySQL service to start on boot..."
systemctl enable mysqld# Confirmation message
echo "MySQL service has been started and set to launch on boot."

安装好了之后通过ssh命令行登陆数据库

mysql -u root

接下来为steve创建相关数据

steve 数据库mysql8
用户名：root
密码：Msb666666@,
Steve数据库用户名：steve
密码：changeme

脚本安装后需要更新默认的随机密码，密码不能太简单，需要带点符合，否则会失败

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Msb666666@,';
FLUSH PRIVILEGES;

创建SteVe需要用到的数据库stevedb

CREATE DATABASE stevedb CHARACTER SET utf8 COLLATE utf8_unicode_ci;

创建完毕后可以使用命令查看一下，可以看到Stevedb

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| stevedb            |
| sys                |
+--------------------+
5 rows in set (0.00 sec)

再为这个数据创建一个数据库用户steve，这个和SteVe平台README.md默认用户名和密码保持一致，否则两边一起改。

CREATE USER 'steve'@'localhost' IDENTIFIED BY 'changeme';
GRANT ALL PRIVILEGES ON stevedb.* TO 'steve'@'localhost';
GRANT SUPER ON *.* TO 'steve'@'localhost';

然后退出数据库尝试使用新数据库用户登陆

  mysql -u steve -p

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| performance_schema |
| stevedb            |
+--------------------+
3 rows in set (0.00 sec)mysql> 

这样就完成了，不需要建表，这个SteVe在打包编译和运行的时候都会自动建表。
编译之前还需要改一下数据库默认时区，解决java编译的时候时区问题。

 vi  /etc/my.cnf

增加default-time-zone=‘+08:00’

重启数据库

 systemctl restart mysqld

数据库好了，还需要Java运行环境

  yum install java-17-openjdk-devel

如果系统里有多个java版本可以使用alternatives来切换

CentOS 支持通过 alternatives 命令来管理多个版本的 Java。您可以按照以下步骤进行设置：

alternatives --install /usr/bin/javac java /usr/lib/jvm/temurin-17-jdk/bin/java 1
alternatives --install /usr/bin/javac javac /usr/lib/jvm/temurin-17-jdk/bin/javac 1

sudo alternatives --config java

选择Java17即可

修改Steve代码
修改Java代码，改到上海时区东八区，方便测试使用

public class Application implements ApplicationStarter, AutoCloseable {private final ApplicationStarter delegate;public Application() {// For Hibernate validatorSystem.setProperty("org.jboss.logging.provider", "slf4j");SteveConfiguration sc = SteveConfiguration.CONFIG;log.info("Loaded the properties. Starting with the '{}' profile", sc.getProfile());// 设置java.util.TimeZone的默认时区为东八区TimeZone.setDefault(TimeZone.getTimeZone("Asia/Shanghai"));       DateTimeZone.setDefault(DateTimeZone.forID("Asia/Shanghai"));//TimeZone.setDefault(TimeZone.getTimeZone(sc.getTimeZoneId()));//DateTimeZone.setDefault(DateTimeZone.forID(sc.getTimeZoneId()));log.info("Date/time zone of the application is set to {}. Current date/time: {}", sc.getTimeZoneId(), DateTime.now());switch (sc.getProfile()) {case DEV:

默认的配置部署到服务器是无法正常访问的，需要修改一下配置，数据库部分一定要和前面配置的数据库的鞥冷信息和端口一样，网页登录信息建议改为自己的密码，最好还是随机密码，修改的java配置文件在src\main\resources\config\prod\main.properties

安装Maven工具，这个是编译这个项目必不可少的工具，

wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

yum install -y apache-maven

[root@iZj6cagyhi0qjy83boeqcyZ ~]# mvn -version
Apache Maven 3.0.5 (Red Hat 3.0.5-17)
Maven home: /usr/share/maven
Java version: 17.0.13, vendor: Eclipse Adoptium
Java home: /usr/lib/jvm/temurin-17-jdk

OS name: "linux", version: "3.10.0-1160.114.2.el7.x86_64", arch: "amd64", family: "unix"

编译代码，生成Java应用程序

./mvnw package

执行并测试

/usr/bin/java -jar /home/steve3.7.1/target/steve.jar

打开网页

能打开基本就成功了，登陆用户名和密码是src\main\resources\config\prod\main.properties里面的

# Credentials for Web interface access
#
auth.user = admin
auth.password = 写上你的密码

手工执行通过后，可以制作自启动Steve服务器

vi /etc/systemd/system/steve.service

systemctl enable steve.service
