配置文件

切换root权限，新建一个nextcloud的文件夹，进入该目录，创建docker-compose.yml

[cps@localhost ~]$ su root

安装部署

docker-compose up -d

本地访问

http:localhost:8008

Nextcloud设置

等待一会

内网穿透

cpolar安装

curl -L https://www.cpolar.com/static/downloads/install-release-cpolar.sh | sudo bash
sudo systemctl enable cpolar
sudo systemctl start cpolar

cpolar登录web

1. https://www.cpolar.com/官网注册账号
2. cpolar安装成功后，在外部浏览器上访问Linux 的9200端口即:【http://服务器的局域网ip:9200】
3. 使用cpolar账号登录，登录后即可看到cpolar web 配置界面，在仪表盘下创建隧道。

配置可信任域名

‘trusted_domains’ => 添加可信任域名5256185a.r1.vip.cpolar.cn

确保docker容器NextCloud、Mysql已开启

[root@localhost nextcloud]# docker ps

问题与解决

bash: docker-compose: command not found…

[root@localhost nextcloud]# docker-compose up -d
bash: docker-compose: command not found...

1. 安装工具源

sudo yum -y install epel-release

2. docker-compose依赖python，安装 python-pip 模块

sudo yum install python-pip

3. 下载docker-compose 安装包

wget https://github.com/docker/compose/releases/download/1.14.0-rc2/docker-compose-Linux-x86_64

4. 重命名工具 docker-compose 名称，并移动到系统可执行目录

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

5. 修改文件的可执行属性

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

6. 验证

docker-compose -version

---

mysql 很多Waiting。。。镜像pull不下来

1. 配置文件

 vi   /etc/docker/daemon.json

{ 
 "registry-mirrors": ["https://studk.mirror.aliyuncs.com","http://f1361db2.m.daocloud.io"] 
} 

2. 重启服务

sudo systemctl restart docker

---

通过不被信任的域名访问

'trusted_domains' =>
  array (
   0 => 'localhost',
   1 => '这里写域名',
),
