Debian12搭建Nextcloud最新版并frp到二级域名

起因：因为台风的原因，要居家办公，但正值公司业务最要紧的时刻，所以需要搭建远程共享，结果发现基于原有的经验，已经难以适应版本更新带来的问题，所以就解决方法，进行了一次重新总结，作为记录，也希望能帮到有类似需求的读者。

关于frp转发 https，请看我的这篇：利用frps搭建本地自签名https服务的透传_lggirls的博客-CSDN博客

一、平台环境的搭建

1.1.Mariadb数据库的安装。

采用apt命令直接安装就可以是 10.11.3版。主要是对其进行设置，开启数据库通过远程登录进行管理的功能。

apt update
apt install mariadb-server
#安装结束，进行配置
mysql_secure_installation
root@Home:~# mysql -u root
##以下为mysql环境下的操作
mysql> select User, host from mysql.user ;   #查看一下当前的账户信息
mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%'  IDENTIFIED BY '147258369' ; #设定root可远程登录
mysql> select User, host from mysql.user ; 再查看一下当前的账户信息，增加了一个 root   %
mysql> quit ；
 
### 备注： 单独设置 root@localhost 的秘密
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '147258369';

1.2. nginx稳定版的安装

当前nginx最常用的是1.22版，但稳定版已经发布到1.24了。对于系统没有最前沿要求的，可以继续apt直接装就可以了。要安装最新版，还是要按照官方说明进行前置环境的安装，然后才可以。

###以下命令是在debian12最小化安装环境进行，没有sudo命令，直接以root账户操作的！！！
##先安装一些必要的软件。主要是下载工具，key、验证文件、源地址文件的导入工具等
 apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring
 
## 下载key文件，并导入
curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
 
## 对下载的文件的验证
gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg
 
## 设置稳定版nginx的安装源的地址
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/debian `lsb_release -cs` nginx" | tee /etc/apt/sources.list.d/nginx.list
 
## 进行声明，告诉debian11系统，按照我们所设定的安装包来进行安装
echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n"     | tee /etc/apt/preferences.d/99nginx
 
## 真正的安装
apt update
apt install nginx

1.3 安装php-fpm

apt 默认安装即可。主要是安装必须的插件

apt install php-fpm php-gd php-mysql php-curl php-mbstring php-intl php-gmp php-bcmath php-xml php-imagick php-zip

1.4 配置nginx和php

#
    location ~ \.php$ {
        root           /usr/share/nginx/nextcloud;
	#fastcgi_pass   127.0.0.1:9000;
	fastcgi_pass unix:/run/php/php-fpm.sock;  ## 这里使用的是sockt连接方式
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/nextcloud$fastcgi_script_name;
        include        /etc/nginx/fastcgi_params;
    }

编写info.php

cat info.php

<?php
phpinfo();
?>

二、 Nextcloud的下载和解压缩

这个比较简单。看官网介绍即可

在debian12 中，我安装的nginx的默认路径是 /usr/share/nginx/html 这里根据配置文件的需要，将nextcloud 直接放在了和html同级别的位置，也是就是 usr/share/nginx/nextcloud

三、配置nextcloud 的nginx虚拟机

vim /etc/nginx/conf.d/cloud.conf

##  内容如下  可以从官网关于nginx的设置说明中找到，这里是禁用了ssl，以便后面使用frp


upstream php-handler {
	# server 127.0.0.1:9000;
    server unix:/var/run/php/php-fpm.sock;
}

# Set the `immutable` cache control options only for assets with a cache busting `v` argument
map $arg_v $asset_immutable {
    "" "";
    default "immutable";
}


server {
    listen 34567;  ## 这两段最好修改一下，因为电信运营商会封一些默认的80、8080、21等常用端口
    listen [::]:34567;
    server_name cloud.abcd.com;

    server_tokens off;

    # Add .mjs as a file extension for javascript

	    #        text/javascript js mjs;
    }

    # Specify how to handle directories -- specifying `/index.php$request_uri`
    # here as the fallback means that Nginx always exhibits the desired behaviour
    # when a client requests a path that corresponds to a directory that exists
    # on the server. In particular, if that directory contains an index.php file,
    # that file is correctly served; if it doesn't, then the request is passed to
    # the front-end controller. This consistent behaviour means that we don't need
    # to specify custom rules for certain paths (e.g. images and other assets,
    # `/updater`, `/ocm-provider`, `/ocs-provider`), and thus
    # `try_files $uri $uri/ /index.php$request_uri`
    # always provides the desired behaviour.
    index index.php index.html /index.php$request_uri;

    # Rule borrowed from `.htaccess` to handle Microsoft DAV clients
    location = / {

    # for `/.well-known`.
    location ^~ /.well-known {
        # The rules in this block are an adaptation of the rules
        # in `.htaccess` that concern `/.well-known`.

        location = /.well-known/carddav { return 301 /remote.php/dav/; }

    }

    location / {

    }
}

四、下载phpMyadmin，配置数据库

五、输入nextcloud所在的主机ip，进行安装

六、特殊的配置

全新安装的nextcloud时，会出现过一会，安装页面出现错误；静等到一切安装完成,输入地址，却出现404错误的问题；还有在进入登录页面后，在确定密码没有错误的情况下，无法通过web页面登录；登录次数过多后，因防暴力试错破解机制，导致延迟登录。本文将解决这几个问题

修改配置文件，加入可登录系统的ip

图中有 0～3 共4个ip，注意没有证书的化，手动输入开头 http:// XXXX-ip/ 来确保非加密网页

/var/lib/php/session 这个文件夹及其中的文件，权限要和 nginx 、php保持一致。

目前新安装的nginx，默认使用的账户是 www-data

chown -R www-data:www-data /var/lib/php/session/

http强制转换为https的问题

不知道从哪个版本开始，安装指导和配置文件内，都开始指向 https了，即便没有申请证书，也会指向和强制把http => https 。修改配置文件，取消这一设定，保持 http就可以了

vim nextcloud/config/config.php

如果以为自己记错了密码，反复登录，会出现IP受限的问题

也可以通过修改配置，取消试错保护的功能。可以登录，问题解决后，再改回来

方法：如第2步，在配置文件中添加一行：

 'auth.bruteforce.protection.enabled' => false,

七、frp和转发服务器nginx的配置

这一部分可以参考 Nextcloud 结合frp搭建私有网盘_frp nextcloud_lggirls的博客-CSDN博客

需要注意的是，在之前的这篇中，还没有强制使用https，比较好转发，但现在不行了。

还有关于转发代理的问题，可以参考：使用frp结合nginx实现对https的反向代理支持_frp+nginx_lggirls的博客-CSDN博客

在本例子中，我们搭建的nextcloud使用的是http协议，在frp和nginx代理后，也是http协议

代理服务器上的配置：

这里的34567 端口，是frps服务器中的virtual_host 的端口

server {
        listen      80 default_server;  
        listen      [::]:80 default_server;
        server_name cloud.abcd.com;
 
        location / {
            proxy_pass http://127.0.0.1:34567; 
        }
    }

八、检查和纠正报警

8.1. 内存低于512M

find / -name 'php.ini'

vim /etc/php/8.2/fpm/php.ini

## 搜索 memory_limit, 将memory_limit = 128M, 修改为大于512的值

8.2 Strict-Transport-Security "max-age=15552000......

vim /etc/nginx/conf.d/test-site.conf


## 将下列内容添加到 ssl_certificate_key 配置项的下一行即可
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

8.3 PHP 的安装似乎不正确，无法访问系统环境变量。getenv("PATH") 函数测试返回了一个空值。

vim A
## 内容如下
env[PATH] = /usr/local/bin:/usr/bin:/bin:/usr/local/php/bin

cat A >> /etc/php/8.2/fpm/php-fpm.conf

8.4 上传文件小于1024K

解决方法： vim /etc/nginx/nginx.conf 在 http { } 段落中，增加一句：

client_max_body_size 0;

8.5 您的安装没有设置默认的电话区域。

vim nextcloud/config/config.php
##增加如下内容
  'default_phone_region' => 'CN',

8.6 内存缓存未配置
