nextcloud x 集群？

不不不，这边只介绍单机配置（

环境准备

1. docker

建议通过软件包管理器(apt/yum)安装,需要添加docker官方源/镜像源
这样便于更新

为了性能考虑，可使用mysql作为数据库服务器

一步一步按照命令走（新手建议，毕竟是经验233

##以下为mysql安装过程
官方文档

1.环境变量（提供参数

mysql8.0及更新需配合php相关插件升级/修改数据库密码方式为native，以下提供一个实例,进入容器并登录mysql，命令行键入类似以下命令

ALTER USER ‘nextcloud‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘new_password‘;

命令形式

export docker_mysql_version = 5.7
export docker_mysql_port = 3306
export docker_mysql_container_name = mysql
export docker_mysql_container_root_password = passwdforrooot 
export docker_mysql_container_user_name = user
export docker_mysql_container_user_password = passwdforuser
export docker_mysql_container_database = nextcloud 

.env形式(环境变量文件，便于部署/保密，与命令形式二选一)

docker_mysql_version = 5.7
docker_mysql_port = 3306
docker_mysql_container_name = mysql
docker_mysql_container_root_password = passwdforrooot 
docker_mysql_container_user_name = user
docker_mysql_container_user_password = passwdforuser
export docker_mysql_container_database = nextcloud 

2.docker命令

docker run \
--name $docker_mysql_container_name \ 
-e MYSQL_ROOT_PASSWORD=$docker_mysql_container_root_password \
-e MYSQL_DATABASE=$docker_mysql_container_database \
-e MYSQL_USER=$docker_mysql_container_user_name \
-e MYSQL_PASSWORD=$docker_mysql_container_user_password \
-p $docker_mysql_port:3306 \
--restart=on-failure:5 \
mysql:$docker_mysql_version

##以下为nextcloud容器安装

1.环境变量

export docker_nextcloud_volume1=~/nextcloud

2.docker命令

docker run -d \
-v $docker_nextcloud_volume1:/var/www/html \
--link $docker_mysql_container_name:mysql
nextcloud

若不使用mysql，请去除

--link $docker_mysql_container_name:mysql
