当用微服务安装系统后，面临服务较多，一个一个安装比较麻烦，是否有统一的脚本可以直接执行安装呢？答案是肯定的：

1、首先介绍一下所有安装脚本，如下图

　　

spd-volume：是各服务外挂的资料卷

common.sh文件主要封装了一些公共的函数，比较docker的安装与检查

daemon.json与dokcer.service文件是安装docker必须的文件

docker-compose.yml文件是安装各服务的yml语法文件

install.conf是配置文件，如服务的端口ip都可在此配置

install.sh程序运行的主命令

2、将所有的安装脚本复制到要安装的linux服务器上面

新建/home/shell/spd-auto文件夹，将所有要安装的文件复制进去

3、修改配置文件，主要是修改如下的镜像的版本，和服务器的ip

4、修改各服务外挂的资料卷文件

以一个文件为例，主要是修改里面的ip地址和数据库连接地址

5、执行命令安装程序

进入到/home/shell/spd-auto文件夹中，执行如下命

./install.sh

如权限不足执行：chmod +x install.sh

如果不出意外，所有的服务都会安装完成

6、还原数据库

注意数据库的名字要与资料卷中的数据库的名称一致。

7、最后将将所有的服务脚本文件代码贴上，有问题请留言，当然脚本还有很多不足的地方，希望大家提出宝贵的建议。

   docker-compose version 1>/dev/null 2>/dev/null

    if [ $? != 0 ];then

       error "docker-compose 未正常安装，请先安装 docker-compose 后再次执行本脚本"

       exit 1

    fi

}

常见问题：

解决方法一（推荐）：

安装docker-compose

1、下载安装包：

官网：https://github.com/docker/compose/releases

百度云下载：

链接：https://pan.baidu.com/s/10In9P2lSLuYL3M7dVhARhQ

提取码：bax3

2、移动文件到指定目录并改名

mv docker-compose-linux-x86_64
/usr/local/bin/docker-compose

3、添加可执行权限

chmod +x
/usr/local/bin/docker-compose

4、命令测试是否安装成功

docker-compose -v 

解决方法二：

1、无法创建符号链接"/usr/bin/docker-compose": 文件已存在

下载docker-compose：curl -SL https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

加个执行权限：chmod +x /usr/local/bin/docker-compose
