docker docker-compose instalar mysql:5.7.31

1. Antecedentes

En la empresa, creo que encontrará muchos servidores de prueba diferentes. Hay mucho trabajo de implementación por hacer entre el personal de operación y mantenimiento. Es necesario conectarse a la base de datos mysql para realizar pruebas y pruebas de estrés. Aquí, elija docker para instalar mysql5.7, que es simple y conveniente.

En cuanto a por qué se elige mysql5.7, es porque la versión de mysql5.7 es estable.En segundo lugar, la instalación es mucho más simple que otras versiones superiores (mysql8), y hay muchas menos operaciones de inicialización como concesión, como acceso denegado para usuario root... ...contraseña no. Ver estos mensajes de error de conexión es un verdadero dolor de cabeza.

2. Instalar docker, docker-compose

Modificar a través del archivo daemon.json

（1）在/etc/docker目录中添加daemon.json文件，内容如下：
        {
              "registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn"]
        }
（2）重启docker服务：
     systemctl restart docker
（3）执行：docker info，查看是否配置成功：

3. Cree un archivo de arreglo docker-compose

# vim docker-compose.yml

version: '3.8'
services:
  mysql:
    container_name: mysql57
    image: mysql:5.7.31
    restart: always
    ports:
      - 3307:3306
    privileged: true
    volumes:
      - $PWD/mysql57/log:/var/log/mysql 
      - $PWD/mysql57/conf/my.cnf:/etc/mysql/my.cnf
      - $PWD/mysql57/data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: "123456"
      MYSQL_USER: 'haima'
      MYSQL_PASS: '123456'
    command: [
        '--character-set-server=utf8mb4',
        '--collation-server=utf8mb4_general_ci',
        '--max_connections=3000'
    ]
    networks:
      - myweb

networks:

  myweb:
    driver: bridge

3. Cree el script de inicialización init-mysql.sh

#!/bin/bash
mkdir -p $PWD/mysql57/{conf,data,log}  #创建本地文件夹


#新建配置文件
tee $PWD/mysql57/conf/my.cnf<<-'EOF'
[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
lower_case_table_names=1 #实现mysql不区分大小（开发需求，建议开启）
# By default we only accept connections from localhost
#bind-address   = 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
default-time_zone = '+8:00'

# 更改字符集 如果想Mysql在后续的操作中文不出现乱码,则需要修改配置文件内容
symbolic-links=0
character-set-server=utf8mb4
[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4

EOF

4. Organización de archivos y estructura de directorios de secuencias de comandos de instalación

[root@centos7 mysql]# chmod +x init-mysql.sh docker-compose.yml  #加执行权限
[root@centos7 mysql]# ./init-mysql.sh

[root@centos7 mysql]# tree ./  #查看目结构
./
├── docker-compose.yml
├── init-mysql.sh
└── mysql57
    ├── conf
    │   └── my.cnf
    ├── data
    └── log

5. Iniciar el servicio

docker-compose up -d
此时服务已经启动成功了.使用角本是不是很爽,嘿嘿...

iniciar sesión en mysql

[root@centos7 mysql57]# docker exec -it mysql57 mysql -uroot -p123456
