参考文章 CentOS7安装Nextcloud13 使用（Nginx+MariaDB+PHP）_WolfBolin技术博客-CSDN博客

环境说明

• 一个带有40G系统盘的轻量级应用服务器（阿里云）
• CentOS 7.3 （阿里云公共镜像）
• SELinux关闭（阿里云CentOS默认配置无需更改）

基础初始化

新服务器中所有自带服务都需要更新

yum -y update

安装 nginx 并添加基础配置

添加 EPEL 和 REMI 包的仓库源

yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

启用 PHP 7.4 Remi存储库

yum -y install yum-utils
yum-config-manager --enable remi-php74

通过 EPEL 仓库来安装 nginx

yum -y install nginx

安装完成之后打开文件 /etc/nginx/nginx.conf ，前五十行中包含以下内容：

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf

在include /etc/nginx/conf.d/*.conf;前面添加如下配置：

    upstream php-handler {
        server 127.0.0.1:9000;
       #server unix:/var/run/php5-fpm.sock;
    }

即：

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
​
    upstream php-handler {
        server 127.0.0.1:9000;
       #server unix:/var/run/php5-fpm.sock;
    }
​
    include /etc/nginx/conf.d/*.conf;

安装 php7 和 php-fpm

添加 webtatic 仓库

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装 php7 以及功能相关的包

yum -y install php php-fpm php-cli php-gd php-mysql php-pear php-xml php-mbstring php-pdo php-intl php-json php-pecl-apcu php-pecl-apcu-devel git

配置 php-fpm

打开文件/etc/php-fpm.d/www.conf，前一百行中包含如下内容：

; RPM: apache Choosed to be able to access some dir as httpd
user = apache
; RPM: Keep a group allowed to write in log dir.
group = apache

将 user 和 group 的值改为 nginx，即：

; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx

为 php-fpm 添加 session 支持

mkdir -p /var/lib/php/session

将 session 添加权限到 nginx

chown nginx:nginx -R /var/lib/php/session/

启动 php-fpm 和 nginx

systemctl start php-fpm
systemctl start nginx

设置 php-fpm 和 nginx 开机自启

systemctl enable php-fpm
systemctl enable nginx

安装MariaDB

这里使用 MariaDB 作为 Nextcloud 的数据库。可以直接使用 yum 命令从 CentOS 默认远程仓库中安装 mariadb-server包。

yum -y install mariadb mariadb-server

systemctl start mariadb
systemctl enable mariadb

配置MariaDB

使用MySQL初始化指令初始化root用户，默认密码为空。

mysql_secure_installation

#配置过程
Set root password? [Y/n] Y
New password:
Re-enter new password:

Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

先使用命令登录MySQL

mysql -u root -p

输入以下 mysql 查询语句来创建新的数据库和用户。

create database nextcloud;
create user nextclouduser@localhost identified by 'nextclouduser@';
grant all privileges on nextcloud_db.* to nextclouduser@localhost identified by 'nextclouduser@';
flush privileges;
exit

安装SSL证书

我们可以自己生成SSL证书，也可以申请专业的SSL证书。
自签名的SSL证书在使用的时候会报错，建议使用有资质的SSL证书。

建议将证书文件放到 nginx 目录下的 cert 文件夹，即 /etc/nginx/cert 文件夹。

下载和初步安装 Nextcloud

找到正确的官方下载库：https://download.nextcloud.com/server/releases/

安装必要的下载解压工具

yum -y install wget unzip

先进入 /tmp 目录，然后使用 wget 从官网下载最新的 Nextcloud 13。

cd
cd /tmp
wget https://download.nextcloud.com/server/releases/nextcloud-21.0.1.zip

解压 Nextcloud，并将其移动到 /var/www 目录。

mkdir /var/www/
unzip nextcloud-13.0.0.zip
mv nextcloud/ /var/www/

手动指定文件储存位置（可选）

若想修改文件储存的位置（比如你另外购买了一块云硬盘）
这时则需要编辑nextcloud的配置文件，修改datadirectory指向的文件夹。

修改 nextcloud 安装目录下文件 nextcloud/config/config.sample.php 。

将 'datadirectory' => '/var/www/owncloud_data/'
修改为 'datadirectory' => '你的路径'

配置Nginx转发规则

我们需要在Nginx的配置文件下写入有关nextcloud的转发协议。
我们可以直接新建一个配置文件并写入信息，当Nginx重新加载后就能使用配置文件了。

在 nginx 配置目录（即 /etc/nginx/conf.d/）中新建文件 nextcloud.conf。

根据个人需要修改并写入配置：

• server_name需要改为域名
• ssl_certificate和ssl_certificate_key需要改为SSL证书对应的文件
• root需要改为nextcloud文件夹所在路径
• 配置数据来自nextcloud官方文档

server {
    listen 80;
    listen [::]:80;
    server_name cloud.example.com;
    # enforce https
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name cloud.example.com;

    ssl_certificate /etc/ssl/nginx/cloud.example.com.crt;
    ssl_certificate_key /etc/ssl/nginx/cloud.example.com.key;

检验一下配置的正确性之后就能用域名访问网盘了

nginx -t
systemctl restart nginx

常见错误

有可能你在访问页面时可以正常显示但是提示你**“内部服务器错误”**，若出现这个情况有两个可能：

• Nginx 对 nextcloud 文件夹的访问权限不够，使用如下操作重新给予权限

cd /var/www
mkdir -p nextcloud/data
chown nginx:nginx -R nextcloud/

• SELinux 未关闭

永久关闭 SELinux 需要编辑文件 /etc/selinux/config，将 SELINUX=enforcing 修改为 SELINUX=disabled ，重启后生效
临时关闭 SELinux 只需要在 shell 中输入 setenforce 0 就可以临时关闭 SELinux 。
