1.簡介
項目介紹：

2.項目部署配置
項目路徑：/root/Documents/NETCore
項目結構：
只顯示主要配置的文件
├── database
└── jhgdsm.sql （數據庫配置）
├── data.dll.config （數據庫連接字符串）
├── Dockerfile （docker配置）
├── proxy.conf （nginx配置）
├── docker-compose.yml（compose配置）
各個配置文件說明如下：
1.jhgdsm.sql ：
文件內容如下：
USE mysql;
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
DROP DATABASE IF EXISTS `jhgdsm`;
CREATE DATABASE jhgdsm;
USE jhgdsm;
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
DROP TABLE IF EXISTS `jh_user`;
CREATE TABLE `jh_user` (
`id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`account` varchar(50) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL,
`password` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`mtype` varchar(2) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '2',
`nickname` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`sex` varchar(2) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '1',
`mstatus` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT 'normal',
`company` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`email` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`mobile` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`img` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`createtime` datetime(0) NULL DEFAULT NULL,
`createuser_id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`updatetime` datetime(0) NULL DEFAULT NULL,
`updateuser_id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`logintime` datetime(0) NULL DEFAULT NULL,
`limitdevcount` int(11) NULL DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
-- ----------------------------
-- Records of jh_user
-- ----------------------------
INSERT INTO `jh_user` VALUES ('effd9698-01ab-49c8-9399-5f4ac7fd8d1b', 'admin', 'F5AAE2AA35E781EE3E1C03957B54F6F3', '1', '管理員11', '', 'normal', 'Giada', '', '', '', '2018-11-15 10:36:55', '', '2019-02-19 15:21:16', 'effd9698-01ab-49c8-9399-5f4ac7fd8d1b', '2019-04-10 17:09:36', 10);
#後面都是一些表的創建，忽略了
該文件是數據庫的數據表結構和數據,用於創建鏡像的時候初始化數據庫。數據庫名爲：jhgdsm，密碼123456。
2.data.dll.config
文件內容如下：
<?xml version="1.0" encoding="utf-8" ?>
<BaseSetting>
<MySqlConnection value="server=db;User ID=root;Password=123456;Database=jhgdsm;Allow User Variables=True;"></MySqlConnection>
</BaseSetting>
該文件就是mysql的連接字符串。注意“server=db”，後面會配置到。
3.Dockerfile
內容如下：
FROM microsoft/dotnet:latest
WORKDIR /app
COPY . /app
EXPOSE 5000
ENV ASPNETCORE_URLS http://*:5000
ENTRYPOINT ["dotnet","GDSMPlateForm.dll"]
FROM指定容器需要的鏡像，GDSMPlateForm.dll是運行項目的dll文件，端口號是5000
4.proxy.conf
內容如下：
server {
listen 8080;
location / {
proxy_pass http://gdsm:5000;
}
}
監聽docker下的8080端口，轉發路徑爲gdsm:5000，注意“gdsm”，後面會配置到。
5.docker-compose.yml
內容如下：
version: '2'
services:
db:
container_name: gdsm.db
image: mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: 123456
volumes:
- ./mysql:/var/lib/mysql
- ./database:/docker-entrypoint-initdb.d/
gdsm:
container_name: gdsm.web
build: .
depends_on:
- db
links:
- db
reverse-proxy:
container_name: gdsm.proxy
image: nginx
depends_on:
- gdsm
ports:
- "80:8080"
volumes:
- ./proxy.conf:/etc/nginx/conf.d/default.conf
以上內容部署了3個服務：
db：數據庫服務，data.dll.config文件的“server=db”相對應。
容器命名爲：gdsm.db，
參數“MYSQL_ROOT_PASSWORD: 123456”是數據庫密碼。
./mysql:/var/lib/mysql：掛載當前項目下的mysql文件夾來持久化存儲。
./database:/docker-entrypoint-initdb.d/：將/database目錄下的文件拷貝到/docker-entrypoint-initdb.d目錄下，也就是拷貝jhgdsm.sql文件。docker會遍歷docker-entrypoint-initdb.d目錄下所有的.sh和.sql後綴的文件並執行。
gdsm：web項目服務
容器命名爲：gdsm.web
build: .表示根據當前路徑來創建鏡像，創建過程與Dockerfile相關。
depends_on：表示依賴於db服務。
links：表示與db服務連接。
reverse-proxy:nginx服務
容器命名爲：gdsm.proxy
依賴於gdsm服務。
本機80端口映射到8080端口
./proxy.conf:/etc/nginx/conf.d/default.conf ：掛載了當前項目下的proxy.conf文件作爲反向代理配置文件。其中該文件下的 "http://gdsm:5000"的gdsm映射的是gdsm服務。
