2.案例实施

2.1 ERP管理系统介绍

企业资源计划即 ERP (Enterprise Resource Planning)，建立在信息技术基础上，以系统化的管理思想，为企业决策层及员工提供决策运行手段的管理平台。由美国 Gartner Group 公司于1990年提出。企业资源计划是 MRP II（企业制造资源计划）下一代的制造业系统和资源计划软件。除了MRP II 已有的生产资源计划、制造、财务、销售、采购等功能外，还有质量管理，实验室管理，业务流程管理，产品数据管理，存货、分销与运输管理，人力资源管理和定期报告系统。在我国 ERP 所代表的含义已经被扩大，用于企业的各类软件，已经统统被纳入 ERP 的范畴。它跳出了传统企业边界，从供应链范围去优化企业的资源，是基于网络经济时代的新一代信息系统。它主要用于改善企业业务流程以提高企业核心竞争力。

ERP 是由美国计算机技术咨询和评估集团 Gartner Group Inc 提出的一种供应链的管理思想。企业资源计划是指建立在信息技术基础上，以系统化的管理思想，为企业决策层及员工提供决策运行手段的管理平台。ERP 系统支持离散型、流程型等混合制造环境，应用范围从制造业扩展到了零售业、服务业、银行业、电信业、政府机关和学校等事业部门，通过融合数据库技术、图形用户界面、第四代查询语言、客户服务器结构、计算机辅助开发工具、可移植的开放系统等对企业资源进行了有效的集成。

2.2 容器化部署MariaDB

（1）基础环境准备

下载软件包并解压：

[root@k8s-master-node1 ~]# curl -O http://mirrors.douxuedu.com/competition/ ERP.tar.gz

[root@k8s-master-node1 ~]# tar -zxvf ERP.tar.gz

导入CentOS基础镜像：

[root@k8s-master-node1 ~]# docker load -i ERP/CentOS_7.9.2009.tar

（2）编写Dockerfile

编写yum源：

[root@k8s-worker-node1 ~]# cd ERP/

[root@k8s-worker-node1 ERP]# vi local.repo
[erp]
name=erp
baseurl=file:///root/yum
gpgcheck=0
enabled=1

编写init.sh脚本：

[root@k8s-worker-node1 ERP]# vi mysql_init.sh
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 8
mysqladmin -u root password 'tshoperp'
mysql -uroot -ptshoperp -e "grant all on *.* to 'root'@'%' identified by 'tshoperp'; flush privileges;"
mysql -uroot -ptshoperp -e " create database jsh_erp;use jsh_erp;source /opt/jsh_erp.sql;"

编写Dockerfile：

[root@k8s-worker-node1 ERP]# vi Dockerfile-mariadb
FROM centos:centos7.9.2009
MAINTAINER Chinaskills
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
ENV LC_ALL en_US.UTF-8
RUN yum -y install mariadb-server
COPY jsh_erp.sql /opt/
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

2.4 容器化部署前端服务

（1）编写Dockerfile

编写Dockerfile：

[root@k8s-worker-node1 ERP]# vi Dockerfile-nginx

COPY nginx/app.tar.gz /
RUN tar -zxvf /app.tar.gz -C /
RUN /bin/bash -c 'echo init ok'
EXPOSE 80
CMD ["nginx","-g","daemon off;"]

#设置容器启动时运行的命令。使用nginx命令启动Nginx服务器，通过-g "daemon off;"参数确保Nginx以前台模式运行，可以让Docker容器保持运行状态，直到Nginx进程终止。

编写docker-compose.yaml编排文件：

[root@k8s-master-node1 ERP]# vi docker-compose.yaml
version: '3'
services:
  erp-mysql:
    restart: always       #设置无论退出状态如何，总是重启该服务。
    image: erp-mysql:v1.0
    container_name: erp-mysql
    environment:
      - "MYSQL_DATABASE=jsh_erp"
    ports:
      - 3306:3306
  erp-redis:
    image: erp-redis:v1.0
    container_name: erp-redis
    restart: always
    ports:
      - 6379:6379
    command: redis-server --port 6379 --requirepass tshoperp --appendonly yes  #设置Redis监听的端口、设置Redis密码、启用AOF持久化。
  erp-server:
    restart: always
    image: erp-service:v1.0
    container_name: erp-server
    ports:
      - 9999:9999

    restart: always
    image: erp-nginx:v1.0
    container_name: erp-web-ui
    ports:
      - 8888:80

查看服务：

[root@k8s-worker-node1 ERP]# docker-compose ps
   Name                 Command               State                    Ports
