idea中通过docker 创建mysql容器 及报错-bash: docker-compose: command not found

1.创建一个springboot项目

1.1在根目录下创建两个文件

• 一个是mysql的脚本文件
• 一个是创建mysql容器的配置文件

略。。。。。。。。。。。。。。 2.创建并连接docker中的mysql容器 2.1通过配置文件docker-compose.yml 创建docker中的mysql容器 最后networks： -  ems会报错先记录一下

version: "3.8"

volumes:
  data:

services:

  mysql:
    image: mysql:8.0
    ports:
      - "3306:3306"
    environment:
      - "MYSQL_ROOT_PASSWORD=root"
      - "MYSQL_DATABASE=ems"
    volumes:
      - data:/var/lib/mysql
      - ./ems.sql:/docker-entrypoint-initdb.d/ems.sql
    networks:
      - ems

2.2连接虚拟主机  2.3编辑名称并选择SFTP 

 2.4在虚拟主机目录下创建ems文件夹，并将提前准备好的sql文件和刚才编辑的配置文件拖入虚拟主机的ems目录下  2.5验证docker-compose

 2.6选择创建的虚拟主机名称

cd 项目目录  cd ems（我的文件名是ems）

 输入命令 docker-compose config 如果得到如下响应 说明地址没有问题

如果出现-bash: docker-compose: command not found报错 请移步至文章末端

启动：docker-compose up -d

报错了：

WARNING: Some networks were defined but are not used by any service: outside
ERROR: Service "mysql" uses an undefined network "ems"

解决办法：修改配置文件加入网络

方法1：

networks:
  network1:
    external: true
    name: ems

方法2：

networks:
  ems:
    driver: bridge（声明要生成的网络）

 

 继续执行命令docker-compose up -d 启动成功

docker ps 查看 已经启动

3.在执行命令过程中遇到了一个-bash: docker-compose: command not found错误 3.1解决报错-bash: docker-compose: command not found

解决办法：
1、安装pip

# yum -y install epel-release
# yum -y install python-pip

2、升级pip

# pip install --upgrade pip

3、安装docker-compose插件

# pip install docker-compose

注意安装插件的时候可以看一下日志是否有报错

我遇到的报错如下

 Traceback (most recent call last):
      File "", line 1, in
    IOError: [Errno 2] No such file or directory: '/tmp/pip-build-e0oyPd/importlib-metadata/setup.py'

 解决办法

度娘一顿操作猛如虎,执行以下命令

pip3 install --upgrade pip

再安装docker-compose就不报错了

[root@localhost ~]# pip3 install docker-compose
[root@localhost ~]# docker-compose -version
docker-compose version 1.29.1, build unknown

4、验证是否安装成功

# docker-compose -version
docker-compose version 1.26.2, build unknown

大功告成！！！！！！
