# 前言
昨天有个朋友让我帮他找个 销售管理系统 ，他是搞批发的，他说自己的电脑很早以前装了个销售管理系统，已经联系不到厂家了，现在这台电脑运行已经越来越慢了，电脑的操作系统还是 XP 的，他怕哪天系统挂了他就没有其他的系统记录销售流水和库存数据了
我大致了解了一下他的需求，然后就开始在 GitHub 上看看有没有免费开源的项目找个给他用，毕竟免费的它香嘛 _
# 华夏 ERP
经过一段时间搜索测试，有的 demo 体验好，但是没有一份比较完善的搭建和使用文档，有的文档很完善，但是功能略复杂，我朋友是个电脑小白，他又接受不了。之所以选择这个 华夏ERP ，是因为它的功能简单符合我朋友的要求，并且搭建起来也非常简单，说干就干，马上盘它。
先把整个项目 download 到本地，看了一下该项目支持 Windows 和 Linux ，我就选择 Linux 吧
# 安装项目
我这边选择的 Linux 操作系统是 CentOS 8 ，看了一下安装文档， linux 需要安装 jdk 和 mysql ，对方已经提供软件包的百度云盘下载地址，把下载下来的软件包用 WinSCP 上传到 CenOS , 用 RPM 命令安装，发现安装 mysql 报错了，缺少依赖，看了一下 mysql-5.8-528 这个版本也太老了，于是决定用 Mariadb 代替。

安装完 mariadb ，用 systemctl 命令启动 mysql 并添加开机启动，然后初始化 MySQL
[root@CentOS ~]# systemctl start mariadb && systemctl enable mariadb | |

[root@CentOS ~]# mysql_secure_installation | |
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB | |
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! | |
In order to log into MariaDB to secure it, we'll need the current | |
password for the root user. If you've just installed MariaDB, and | |
you haven't set the root password yet, the password will be blank, | |
so you should just press enter here. | |
Enter current password for root (enter for none): | |
OK, successfully used password, moving on... | |
Setting the root password ensures that nobody can log into the MariaDB | |
root user without the proper authorisation. | |
Set root password? [Y/n] | |
New password: | |
Re-enter new password: | |
Password updated successfully! | |
Reloading privilege tables.. | |
... Success! | |
By default, a MariaDB installation has an anonymous user, allowing anyone | |
to log into MariaDB without having to have a user account created for | |
them. This is intended only for testing, and to make the installation | |
go a bit smoother. You should remove them before moving into a | |
production environment. | |
Remove anonymous users? [Y/n] | |
... Success! | |
Normally, root should only be allowed to connect from 'localhost'. This | |
ensures that someone cannot guess at the root password from the network. | |
Disallow root login remotely? [Y/n] n | |
... skipping. | |
By default, MariaDB comes with a database named 'test' that anyone can | |
access. This is also intended only for testing, and should be removed | |
before moving into a production environment. | |
Remove test database and access to it? [Y/n] | |
- Dropping test database... | |
... Success! | |
- Removing privileges on test database... | |
... Success! | |
Reloading the privilege tables will ensure that all changes made so far | |
will take effect immediately. | |
Reload privilege tables now? [Y/n] | |
... Success! | |
Cleaning up... | |
All done! If you've completed all of the above steps, your MariaDB | |
installation should now be secure. | |
Thanks for using MariaDB! |
用 Navicat 15 for MariaDB 连接数据库发现连不上，用 telnet 测试发现端口不通
关闭 firewalld 再测试连接正常，但是登陆后依然报错估计是权限问题
登录 mysql 添加权限后，再用 Navicat 15 for MariaDB 连接登录正常了
[root@CentOS ~]# mysql -uroot -p | |

新建一个数据库，数据库名 jsh_erp , 字符集 utf8 , 排序 utf8_general_ci
导入数据库数据需要 运行项目sql文件 ，sql 文件在项目根目录的 docs 文件夹下面，看到提示 sucessfully 就代表数据库导入成功，刷新数据库，可以看到里面的数据表
# 项目配置
现在需要用 maven 将项目打包， Windows 需要安装 JDK ，并配置系统环境变量
然后把 apache-maven-3.2.3-bin.zip 解压出来，我这边解压到 E 盘根目录，然后在 path 变量添加 apache-maven-3.2.3\bin 的路径
最后用 mvn 命令打包项目，打开 cmd ，用 cd 命令切换到项目根目录，输入 mvn clean install 将项目打包，这个过程应该需要等待挺长时间的，反正我等了差不多十分钟，取决于你的网速。
命令执行完后显示 success 表示打包完成，此时目录多了一个 dist 的目录，把里面的 jshERP2.0-bin.zip 解压出来上传到 CentOS
ssh 连接 CentOS ，进入 jshERP2.0/config 目录，编辑 application.properties 文件，更改数据库的用户名和密码，web 端口默认 8080 ，需要的自己更改
[root@CentOS ~]# cd jshERP2.0/ | |
[root@CentOS jshERP2.0]# ls | |
bin config docs erp_web lib logs README.md restart.sh start.bat start.sh status.sh stop.sh | |
[root@CentOS jshERP2.0]# cd config/ | |
[root@CentOS config]# ls | |
application.properties logback-spring.xml | |
[root@CentOS config]# vi application.properties |
更改完后，用 chmod -R 755 jshERP2.0 更改根目录权限，添加权限后运行 start.sh 脚本启动，提示 Starting ... SUCCESS! 说明程序运行成功
此时打开了浏览器，输入 CenotOS 主机的 IP 地址端口号 8080 ，成功显示登录页面，注册个账户登录正常
Note：
如果脚本运行成功无法访问，请检查是否被防火墙拦截了。
如果脚本运行失败，则检测 application.properties 配置的 mysql 用户名和密码是否有误。
本地测试了一下没有发现什么问题，就直接把项目部署到自己阿里云服务器了，然后告诉我朋友域名和端口，剩下的就靠他自己去摸索了，毕竟我也不会用
