搭建个人云存储一般会想到ownCloud,堪称是自建云存储服务的经典。而Nextcloud是ownCloud原开发团队打造的号称是“下一代”存储。初一看觉得“口气”不小,刚推出来就重新“定义”了Cloud,真正试用过后就由衷地赞同这个Nextcloud:它是个人云存储服务的绝佳选择。可以说Nextcloud 是一款* (开源) 的类 Dropbox 软件,由 ownCloud 分支演化形成。它使用 PHP 和 JavaScript 编写,支持多种数据库系统,比如 MySQL/MariaDB、PostgreSQL、Oracle 数据库和 SQLite。它可以使你的桌面系统和云服务器中的文件保持同步,Nextcloud 为 Windows、Linux、Mac、安卓以及苹果手机都提供了客户端支持。同时,Nextcloud 也并非只是 Dropbox 的克隆,它还提供了很多附加特性,如日历、联系人、计划任务以及流媒体 Ampache。
与ownCloud相比,Nextcloud的功能丝毫没有减弱,甚至由于可以安装云存储服务应用,自制性更强,也更符合用户的需求。Nextcloud官网的帮助文档写得相当地详细,几乎任何关于Nextcloud的问题都可以找到答案,这说明Nextcloud开发团队确实比ownCloud更加优秀。
一开始以为Nextcloud只是一个网盘云存储,后来看到Nextcloud内置了Office文档、图片相册、日历联系人、两步验证、文件管理、RSS阅读等丰富的应用,我发现Nextcloud已经仅仅可以用作个人或者团队存储与共享,还可以打造成为一个个人办公平台,几乎相当于一个个人的Dropbox了。
以下内容将介绍如何在 CentOS 7 服务器中安装和配置最新版本的 Nextcloud 12,并且会通过 Nginx 和 PHP7-FPM 来运行 Nextcloud,同时使用 MariaDB 做为数据库系统。Nextcloud云盘环境部署后,可以实现web网页端、手机移动端和桌面客户端三者数据同步,其中桌面客户端可以在本地设置一个文件夹,用于同步数据,这样也就相当于在本地备份了数据。同时客户端只要设置开机启动,即只要是启动状态中,它和网页端的数据就是自动同步的。废话不多说了,直接看部署笔记:
部署机器的系统是Centos7.4版本 [root@nextcloud-server ~]# cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) 一、安装并配置Nginx和php-fpm ================================================================ 将自带的epel、nginx、php全部卸载(rpm -e ... --nodeps) [root@nextcloud-server ~]# rpm -qa|grep php [root@nextcloud-server ~]# rpm -qa|grep php-common [root@nextcloud-server ~]# rpm -qa|grep nginx =============================================================== CentOS默认的yum源中并不包含Nginx和php-fpm,首先要为CentOS添加epel源: [root@nextcloud-server ~]# yum -y install epel-release [root@nextcloud-server ~]# yum -y install nginx 需要再添加一个yum源来安装php-fpm,可以使用webtatic(这个yum源对国内网络来说恐怕有些慢,当然你也可以选择其它的yum源) [root@nextcloud-server ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 安装php7-fpm和一些其它的必要的组件 [root@nextcloud-server ~]# yum -y install php70w-fpm php70w-cli php70w-gd php70w-mcrypt php70w-mysql php70w-pear php70w-xml php70w-mbstring php70w-pdo php70w-json php70w-pecl-apcu php70w-pecl-apcu-devel 完成后,检查一下php-fpm是否已正常安装 [root@nextcloud-server ~]# php -v PHP 7.0.25 (cli) (built: Oct 29 2017 13:43:03) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies 配置php-fpm [root@nextcloud-server ~]# vim /etc/php-fpm.d/www.conf ..... user = nginx //将用户和组都改为nginx group = nginx ..... listen = 127.0.0.1:9000 //php-fpm所监听的端口为9000 ...... env[HOSTNAME] = $HOSTNAME //去掉下面几行注释 env[PATH] = /usr/local/bin:/usr/bin:/bin env[TMP] = /tmp env[TMPDIR] = /tmp env[TEMP] = /tmp 在/var/lib目录下为session路径创建一个新的文件夹,并将用户名和组设为nginx [root@nextcloud-server ~]# mkdir -p /var/lib/php/session [root@nextcloud-server ~]# chown nginx:nginx -R /var/lib/php/session/ [root@nextcloud-server ~]# ll -d /var/lib/php/session/ drwxr-xr-x. 2 nginx nginx 4096 1月 25 09:47 /var/lib/php/session/ 启动Nginx和php-fpm服务,并添加开机启动 [root@nextcloud-server ~]# systemctl start php-fpm [root@nextcloud-server ~]# systemctl start nginx [root@nextcloud-server ~]# systemctl enable php-fpm [root@nextcloud-server ~]# systemctl enable nginx 二、安装并配置MariaDB 使用MaraiDB作为Nextcloud数据库。yum安装MaraiDB服务 [root@nextcloud-server ~]# yum -y install mariadb mariadb-server 启动MariaDB服务并添加开机启动 [root@nextcloud-server ~]# systemctl start mariadb [root@nextcloud-server ~]# systemctl enable mariadb 接下来设置MariaDB的root密码 [root@nextcloud-server ~]# mysql_secure_installation //按照提示设置密码,首先会询问当前密码,密码默认为空,直接回车即可 Enter current password for root (enter for none): //直接回车 Set root password? [Y/n] Y New password: //输入新密码 Re-enter new password: //再次输入新密码 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 ============================================================================================== 或者采用另一种修改密码的方式:跳过授权表 1)在/etc/my.cnf文件里添加"skip-grant-tables" 2)重启mariadb服务 3)无密码登陆mariadb,然后重置mysql密码 MariaDB [(none)]> update mysql.user set password=password("kevin@123") where user="root"; 4)去掉/etc/my.cnf文件里的"skip-grant-tables"内容 5)重启mariadb服务 6)这样就可以使用上面重置的新密码kevin@123登陆mariadb了 ============================================================================================== 设置完MariaDB的密码后,使用命令行登录MariaDB,并为Nextcloud创建相应的用户和数据库。 例如数据库为nextcloud_db,用户为nextclouduser,密码为nextcloudpasswd: [root@nextcloud-server ~]# mysql -p ...... MariaDB [(none)]> create database nextcloud_db; MariaDB [(none)]> create user nextclouduser@localhost identified by 'nextcloudpasswd'; MariaDB [(none)]> grant all privileges on nextcloud_db.* to nextclouduser@localhost identified by 'nextcloudpasswd'; MariaDB [(none)]> flush privileges; 三、为Nextcloud生成自签名SSL证书 为SSL证书创建一个新的文件夹: [root@nextcloud-server ~]# cd /etc/nginx/cert/ [root@nextcloud-server cert]# openssl req -new -x509 -days 365 -nodes -out /etc/nginx/cert/nextcloud.crt -keyout /etc/nginx/cert/nextcloud.key ..... Country Name (2 letter code) [XX]:cn //国家 State or Province Name (full name) []:beijing //省份 Locality Name (eg, city) [Default City]:beijing //地区名字 Organization Name (eg, company) [Default Company Ltd]:kevin //公司名 Organizational Unit Name (eg, section) []:Technology //部门 Common Name (eg, your name or your server's hostname) []:kevin //CA主机名 Email Address []:kevin@wangshibo.cn 然后将证书文件的权限设置为660 [root@nextcloud-server cert]# chmod 700 /etc/nginx/cert [root@nextcloud-server cert]# chmod 600 /etc/nginx/cert/* 四、下载并安装Nextcloud [root@nextcloud-server ~]# yum -y install wget unzip [root@nextcloud-server ~]# cd /usr/local/src/ [root@nextcloud-server src]# wget https://download.nextcloud.com/server/releases/nextcloud-12.0.4.zip [root@nextcloud-server src]# unzip nextcloud-12.0.4.zip [root@nextcloud-server src]# ls nextcloud nextcloud-12.0.4.zip [root@nextcloud-server src]# mv nextcloud /usr/share/nginx/html/ 进入Nginx的root目录,并为Nextcloud创建data目录,将Nextcloud的用户和组修改为nginx [root@nextcloud-server src]# cd /usr/share/nginx/html/ [root@nextcloud-server html]# mkdir -p nextcloud/data/ [root@nextcloud-server html]# chown nginx:nginx -R nextcloud/ [root@nextcloud-server html]# ll -d nextcloud drwxr-xr-x. 15 nginx nginx 4096 1月 24 17:04 nextcloud 五、设置Nginx虚拟主机 进入Nginx的虚拟主机配置文件所在目录并创建一个新的虚拟主机配置(记得修改两个server_name为自己的域名): [root@nextcloud-server ~]# cd /etc/nginx/conf.d/ [root@nextcloud-server conf.d]# vim nextcloud.conf upstream php-handler { server 127.0.0.1:9000; #server unix:/var/run/php5-fpm.sock; } server { listen 80; server_name nextcloud.kevin-inc.com; # enforce https return 301 https://$server_name$request_uri; } server { listen 443 ssl; server_name nextcloud.kevin-inc.com;

# Optional: Don't log access to other assets access_log off; } } 接下来测试以下配置文件是否有错误,确保没有问题后重启Nginx服务。 [root@nextcloud-server conf.d]# nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [root@nextcloud-server conf.d]# systemctl restart nginx 六、为Nextcloud设置Firewalld防火墙和SELinux 可以选择关闭Firewalld和SELinux [root@nextcloud-server ~]# systemctl stop firewalld [root@nextcloud-server ~]# systemctl disable firewalld [root@nextcloud-server ~]# setenforce 0 [root@nextcloud-server ~]# getenforce disable [root@nextcloud-server ~]# cat /etc/sysconfig/selinux ...... SELINUX=disabled 如果打开了防火墙,则需要设置Firewalld和SELinux 首先需要安装SElinux管理工具policycoreutils-python [root@nextcloud-server ~]# yum -y install policycoreutils-python 接着设置SELinux [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/data(/.*)?' [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/config(/.*)?' [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/apps(/.*)?' [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/assets(/.*)?' [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/.htaccess' [root@nextcloud-server ~]# semanage fcontext -a -t httpd_sys_rw_content_t '/usr/share/nginx/html/nextcloud/.user.ini' [root@nextcloud-server ~]# restorecon -Rv '/usr/share/nginx/html/nextcloud/' 接下来设置Firewlld防火墙,为Nextcloud开放http和https两个端口 [root@nextcloud-server ~]# systemctl start firewalld [root@nextcloud-server ~]# systemctl enable firewalld [root@nextcloud-server ~]# firewall-cmd --permanent --add-service=http [root@nextcloud-server ~]# firewall-cmd --permanent --add-service=https [root@nextcloud-server ~]# firewall-cmd --reload 七、安装Nextcloud 解析上面nginx中配置的域名nextcloud.kevin-inc.com,访问访问http://nextcloud.kevin-inc.com进行Nextcloud界面安装(访问http域名会自动跳转到https,安装提示安装即可!)
==================NextCloud安全与性能优化==================
这种提示一般在NextCloud的服务器管理中可以看到,建议缓存类的直接安装一个即可,安装多了也没有什么用。 为了Nextcloud服务的安全和性能, 请将所有设置配置正确. PHP 模块 ‘fileinfo’ 缺失. 我们强烈建议启用此模块以便在 MIME 类型检测时获得最准确的结果. HTTP 请求头 “Strict-Transport-Security” 没有配置为至少 “15552000” 秒. 出于增强安全性考虑, 推荐按照安全提示中的说明启用HSTS. 内存缓存未配置. 如果可用, 需要配置 memcache 以增强性能. PHP 的组件 OPcache 没有正确配置. 为了提供更好的性能, 我们建议在php.ini文件中使用下列设置: opcache.enable=1 opcache.enable_cli=1 opcache.interned_strings_buffer=8 opcache.max_accelerated_files=10000 opcache.memory_consumption=128 opcache.save_comments=1 opcache.revalidate_freq=1
==================NextCloud添加Memcached缓存=============
修改nextcloud程序目录下的config目录中的config.php文件,在配置文件中添加如下,这个是多个Memcached实例,单个自己改: 'memcache.local' => '\OC\Memcache\APCu', 'memcache.distributed' => '\OC\Memcache\Memcached', 'memcached_servers' => array( array('localhost', 11211), array('server1.example.com', 11211), array('server2.example.com', 11211), ), ================================================================== 依据本篇如上安装记录,添加memcache缓存的方法(本机单机安装memcahced) [root@nextcloud src]# yum -y install memcached [root@nextcloud src]# cat /etc/sysconfig/memcached PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="" [root@nextcloud src]# systemctl start memcached [root@nextcloud src]# systemctl enable memcached Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service. [root@nextcloud src]# lsof -i:11211 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME memcached 146026 memcached 26u IPv4 3320544 0t0 TCP *:memcache (LISTEN) memcached 146026 memcached 27u IPv6 3320545 0t0 TCP *:memcache (LISTEN) memcached 146026 memcached 28u IPv4 3320549 0t0 UDP *:memcache memcached 146026 memcached 29u IPv6 3320550 0t0 UDP *:memcache 修改nextcloud的config配置文件,添加memcached缓存配置 [root@nextcloud config]# pwd /usr/share/nginx/html/nextcloud/config [root@nextcloud config]# cp config.php config.php.bak [root@nextcloud config]# vim config.php ...... 'memcache.local' => '\OC\Memcache\APCu', 'memcache.distributed' => '\OC\Memcache\Memcached', 'memcached_servers' => array( array('localhost', 11211), ),
==================NextCloud添加Redis缓存==================
在nextcloud的config配置文件中添加如下,这个是通过TCP连接的: 'memcache.local' => '\OC\Memcache\Redis', 'redis' => array( 'host' => 'localhost', 'port' => 6379, ), 还有性能更好的UNIX连接: 'memcache.local' => '\OC\Memcache\Redis', 'redis' => array( 'host' => '/var/run/redis/redis.sock', 'port' => 0, 'dbindex' => 0, 'password' => 'secret', 'timeout' => 1.5, ), 同时,官方还推荐加入如下,来用于存储文件锁: 'memcache.locking' => '\OC\Memcache\Redis',
========Nextcloud的邮件发信设置========
Nextcloud发送邮件信息的前提:每个用户(包括管理员)都要事先设置好自己的邮箱地址!
1)使用管理员账号登陆Nextcloud。点击右上角的设置图标里的"管理"-"其他设置"
前提是管理员(admin)要事先设置好自己的邮箱地址。如下设置好邮箱地址后,按Enter键后就会显示一个"对勾"
满足条件:
1)在admin登陆后的"管理"->"其他设置"的后台里配置好"电子邮件服务器"(配置后可以测试发送邮件是否成功,前提是admin也要事先配置好自己的邮箱地址) 2)各用户创建并登陆后,要记得配置各自的邮箱地址。比如wangshibo用户登录后,配置自己的邮箱地址 3)在分享文件的时候,只要使用对方账号名进行分享,对方邮箱里就会收到一封分享信息的邮件!
如下,在admin账号下分享Nextcloud Manual.pdf这个文件给wangshibo用户
然后登陆wangshibo用户,就会发现Nextcloud Manual.pdf文件已经分享过来了
登陆wangshibo账号配置的邮箱,就会发现有上面分享的邮件信
也可以在文件来源方取消分享
==========云盘上传文件大小限制==============
nextcloud上传文件大小的自身限制为512M,如果要想调整这个大小,操作方法如下:
1)修改php.ini上传文件大小限制 [root@nextcloud ~]# vim /etc/php.ini ...... max_execution_time = 0 #默认是30秒,改为0,表示没有限制 ...... post_max_size = 10800M #设定 POST 数据所允许的最大大小,如果POST数据尺寸大于post_max_size $_POST 和 $_FILES superglobals 便会为空. ...... upload_max_filesize = 10240M #表示所上传的文件的最大大小 #另外要说明的是,post_max_size 大于 upload_max_filesize 为佳. 2)修改nginx.conf [root@nextcloud ~]# vim /etc/nginx/conf.d/nextcloud.conf ..... client_max_body_size 10240M; 3)重启php和nginx服务 [root@nextcloud ~]# systemctl restart php-fpm [root@nextcloud ~]# systemctl restart nginx
==========云盘创建新用户==============
碰到一个问题:在admin管理员登录nextclod,点击右上角的"用户",创建新用户时候,点击"创建"无反应,即无法在web界面里创建新用户!
此时可以去数据库中创建新用户:
[root@nextcloud ~]# mysql -pnextcloud@123 Welcome to the MariaDB monitor. Commands end with ; or \g.
