| 4 | +###命令: vim`docker-compose.yml` # 建立`docker-compose` 部署文件 |
| 5 | + |
| 6 | +``` |
| 7 | +version: '3.1' |
| 8 | +services: |
| 9 | + db: |
| 10 | + image: mysql |
| 11 | + command: --default-authentication-plugin=mysql_native_password |
| 12 | + restart: always |
| 13 | + environment: |
| 14 | + MYSQL_ROOT_PASSWORD: test-mysql@2022 |
| 15 | + ports: |
| 16 | + - 53306:3306 |

| 19 | + image: adminer |
| 20 | + restart: always |
| 21 | + ports: |
| 22 | + - 10086:8080 |
| 23 | +``` |
| 24 | + |
| 25 | +###使用`linuxserver/docker-compose` 部署 MYSQL 和 adminer 服务 |
| 26 | + |
| 27 | +``` |
| 28 | +docker run --rm \ |
| 29 | + -v /var/run/docker.sock:/var/run/docker.sock \ |
| 30 | + -v "$PWD:$PWD" \ |
| 31 | + -w="$PWD" \ |
| 32 | + linuxserver/docker-compose \ |
| 33 | + up |
| 34 | +``` |
| 35 | + |
| 36 | +###部署完成，浏览器访问`http://ip:10086` 登陆管理建立数据库 |
| 37 | + |
| 38 | +- 可以web-ui建立数据库和添加用户，也可以使用执行 sql 命令完成创建用户 |
| 39 | + |
| 40 | +``` |
| 41 | +# 创建数数据库: world |
| 42 | +CREATE DATABASE `world` COLLATE 'utf8mb4_bin'; |
| 43 | +
|
| 44 | +# 创建用户密码 |
| 45 | +CREATE USER 'test'@'%' IDENTIFIED BY 'NSbgs4Z8nYAnqhW'; |
| 46 | +
|
| 47 | +# 修改用户密码 |
| 48 | +SET PASSWORD FOR 'test'@'localhost' = 'test@localhost'; |
| 49 | +
|
| 50 | +# 修改远程链接的用户 |
| 51 | +CREATE USER 'test22'@'%' IDENTIFIED BY 'NSbgs4Z8nYAnqhW'; |
| 52 | +GRANT ALL PRIVILEGES ON `world`.* TO 'test22'@'%'; |
| 53 | +``` |
| 54 | +SQL命令中的 'test22'@'%' 可以这样理解: test22是用户名，%是主机名或IP地址，这里的%代表任意主机或IP地址， |
| 55 | +你也可替换成任意其它用户名或指定唯一的IP地址；'MyPassword'是给授权用户指定的登录数据库的密码 |
| 56 | + |

| 58 | + |
| 59 | +###`CREATE TABLE` 创建`City` 数据表，如果已经存在，使用`DROP TABLE` 先删除 |
| 60 | + |
| 61 | +``` |
| 62 | +# DROP TABLE IF EXISTS `City`; |
| 63 | +CREATE TABLE `City` ( `ID` int, `Name` text, `CountryCode` text, |
| 64 | +`District` text, `Population` int ); |
| 65 | +``` |
| 66 | + |
| 67 | +###`INSERT INTO` 向`City` 数据表插入数据，或者使用备份的出来的数据导入`City.sql.gz`[下载](https://github.com/hongwenjun/vps_setup/raw/remove/mysql/City.sql.gz) |
| 68 | +-`City.sql.gz`[下载](https://github.com/hongwenjun/vps_setup/raw/remove/mysql/City.sql.gz) |
| 69 | + |
| 70 | +``` |
| 71 | +INSERT INTO `City` (`ID`, `Name`, `CountryCode`, `District`, `Population`) VALUES |
| 72 | +(1,'Kabul','AFG','Kabol',1780000), |
| 73 | +(2,'Qandahar','AFG','Qandahar',237500), |
| 74 | +(3,'Herat','AFG','Herat',186800), |
| 75 | +(4,'Mazar-e-Sharif','AFG','Balkh',127800), |
| 76 | +(5,'Amsterdam','NLD','Noord-Holland',731200), |
| 77 | +
|
| 78 | +(4078,'Nablus','PSE','Nablus',100231), |
| 79 | +(4079,'Rafah','PSE','Rafah',92020); |
| 80 | +
|
| 81 | +``` |
| 82 | + |
| 83 | +##使用php远程访问学习示例 |
| 84 | + |
| 85 | +###在建立php环境的机器上，使用命令行测试 |
| 86 | + |
| 87 | +``` |
| 88 | +docker exec -it nginx-php bash |
| 89 | +php -a |
| 90 | +
|
| 91 | +$link = mysqli_connect("18.18.18.18", "test22", "NSbgs4Z8nYAnqhW", "world","53306"); |
