搭建個人雲存儲一般會想到ownCloud,堪稱是自建雲存儲服務的經典。而Nextcloud是ownCloud原開發團隊打造的號稱是“下一代”存儲。初一看覺得“口氣”不小,剛推出來就重新“定義”了Cloud,真正試用過后就由衷地贊同這個Nextcloud:它是個人雲存儲服務的絕佳選擇。可以說Nextcloud 是一款自由 (開源) 的類 Dropbox 軟件,由 ownCloud 分支演化形成。它使用 PHP 和 JavaScript 編寫,支持多種數據庫系統,比如 MySQL/MariaDB、PostgreSQL、Oracle 數據庫和 SQLite。它可以使你的桌面系統和雲服務器中的文件保持同步,Nextcloud 為 Windows、Linux、Mac、安卓以及蘋果手機都提供了客戶端支持。同時,Nextcloud 也並非只是 Dropbox 的克隆,它還提供了很多附加特性,如日歷、聯系人、計划任務以及流媒體 Ampache。
與ownCloud相比,Nextcloud的功能絲毫沒有減弱,甚至由於可以安裝雲存儲服務應用,自制性更強,也更符合用戶的需求。Nextcloud官網的幫助文檔寫得相當地詳細,幾乎任何關於Nextcloud的問題都可以找到答案,這說明Nextcloud開發團隊確實比ownCloud更加優秀。
一開始以為Nextcloud只是一個網盤雲存儲,后來看到Nextcloud內置了Office文檔、圖片相冊、日歷聯系人、兩步驗證、文件管理、RSS閱讀等豐富的應用,我發現Nextcloud已經僅僅可以用作個人或者團隊存儲與共享,還可以打造成為一個個人辦公平台,幾乎相當於一個個人的Dropbox了。
以下內容將介紹如何在 CentOS 7 服務器中安裝和配置最新版本的 Nextcloud 12,並且會通過 Nginx 和 PHP7-FPM 來運行 Nextcloud,同時使用 MariaDB 做為數據庫系統。Nextcloud雲盤環境部署后,可以實現web網頁端、手機移動端和桌面客戶端三者數據同步,其中桌面客戶端可以在本地設置一個文件夾,用於同步數據,這樣也就相當於在本地備份了數據。同時客戶端只要設置開機啟動,即只要是啟動狀態中,它和網頁端的數據就是自動同步的。廢話不多說了,直接看部署筆記:
部署機器的系統是Centos7.4版本 [root@nextcloud-server ~]# cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) 一、安裝並配置Nginx和php-fpm ================================================================ 將自帶的epel、nginx、php全部卸載(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默認的yum源中並不包含Nginx和php-fpm,首先要為CentOS添加epel源: [root@nextcloud-server ~]# yum -y install epel-release [root@nextcloud-server ~]# yum -y install nginx 需要再添加一個yum源來安裝php-fpm,可以使用webtatic(這個yum源對國內網絡來說恐怕有些慢,當然你也可以選擇其它的yum源) [root@nextcloud-server ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 安裝php7-fpm和一些其它的必要的組件 [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,檢查一下php-fpm是否已正常安裝 [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 //將用戶和組都改為nginx group = nginx ..... listen = 127.0.0.1:9000 //php-fpm所監聽的端口為9000 ...... env[HOSTNAME] = $HOSTNAME //去掉下面幾行注釋 env[PATH] = /usr/local/bin:/usr/bin:/bin env[TMP] = /tmp env[TMPDIR] = /tmp env[TEMP] = /tmp 在/var/lib目錄下為session路徑創建一個新的文件夾,並將用戶名和組設為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/ 啟動Nginx和php-fpm服務,並添加開機啟動 [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、安裝並配置MariaDB 使用MaraiDB作為Nextcloud數據庫。yum安裝MaraiDB服務 [root@nextcloud-server ~]# yum -y install mariadb mariadb-server 啟動MariaDB服務並添加開機啟動 [root@nextcloud-server ~]# systemctl start mariadb [root@nextcloud-server ~]# systemctl enable mariadb 接下來設置MariaDB的root密碼 [root@nextcloud-server ~]# mysql_secure_installation //按照提示設置密碼,首先會詢問當前密碼,密碼默認為空,直接回車即可 Enter current password for root (enter for none): //直接回車 Set root password? [Y/n] Y New password: //輸入新密碼 Re-enter new password: //再次輸入新密碼 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 ============================================================================================== 或者采用另一種修改密碼的方式:跳過授權表 1)在/etc/my.cnf文件里添加"skip-grant-tables" 2)重啟mariadb服務 3)無密碼登陸mariadb,然后重置mysql密碼 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"內容 5)重啟mariadb服務 6)這樣就可以使用上面重置的新密碼kevin@123登陸mariadb了 ============================================================================================== 設置完MariaDB的密碼后,使用命令行登錄MariaDB,並為Nextcloud創建相應的用戶和數據庫。 例如數據庫為nextcloud_db,用戶為nextclouduser,密碼為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、為Nextcloud生成自簽名SSL證書 為SSL證書創建一個新的文件夾: [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 //國家 State or Province Name (full name) []:beijing //省份 Locality Name (eg, city) [Default City]:beijing //地區名字 Organization Name (eg, company) [Default Company Ltd]:kevin //公司名 Organizational Unit Name (eg, section) []:Technology //部門 Common Name (eg, your name or your server's hostname) []:kevin //CA主機名 Email Address []:kevin@wangshibo.cn 然后將證書文件的權限設置為660 [root@nextcloud-server cert]# chmod 700 /etc/nginx/cert [root@nextcloud-server cert]# chmod 600 /etc/nginx/cert/* 四、下載並安裝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/ 進入Nginx的root目錄,並為Nextcloud創建data目錄,將Nextcloud的用戶和組修改為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、設置Nginx虛擬主機 進入Nginx的虛擬主機配置文件所在目錄並創建一個新的虛擬主機配置(記得修改兩個server_name為自己的域名): [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; } } 接下來測試以下配置文件是否有錯誤,確保沒有問題后重啟Nginx服務。 [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、為Nextcloud設置Firewalld防火牆和SELinux 可以選擇關閉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 如果打開了防火牆,則需要設置Firewalld和SELinux 首先需要安裝SElinux管理工具policycoreutils-python [root@nextcloud-server ~]# yum -y install policycoreutils-python 接着設置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/' 接下來設置Firewlld防火牆,為Nextcloud開放http和https兩個端口 [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、安裝Nextcloud 解析上面nginx中配置的域名nextcloud.kevin-inc.com,訪問訪問http://nextcloud.kevin-inc.com進行Nextcloud界面安裝(訪問http域名會自動跳轉到https,安裝提示安裝即可!)
==================NextCloud安全與性能優化==================
這種提示一般在NextCloud的服務器管理中可以看到,建議緩存類的直接安裝一個即可,安裝多了也沒有什么用。 為了Nextcloud服務的安全和性能, 請將所有設置配置正確. PHP 模塊 ‘fileinfo’ 缺失. 我們強烈建議啟用此模塊以便在 MIME 類型檢測時獲得最准確的結果. HTTP 請求頭 “Strict-Transport-Security” 沒有配置為至少 “15552000” 秒. 出於增強安全性考慮, 推薦按照安全提示中的說明啟用HSTS. 內存緩存未配置. 如果可用, 需要配置 memcache 以增強性能. PHP 的組件 OPcache 沒有正確配置. 為了提供更好的性能, 我們建議在php.ini文件中使用下列設置: 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緩存=============
修改nextcloud程序目錄下的config目錄中的config.php文件,在配置文件中添加如下,這個是多個Memcached實例,單個自己改: '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), ), ================================================================== 依據本篇如上安裝記錄,添加memcache緩存的方法(本機單機安裝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緩存配置 [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緩存==================
在nextcloud的config配置文件中添加如下,這個是通過TCP連接的: 'memcache.local' => '\OC\Memcache\Redis', 'redis' => array( 'host' => 'localhost', 'port' => 6379, ), 還有性能更好的UNIX連接: 'memcache.local' => '\OC\Memcache\Redis', 'redis' => array( 'host' => '/var/run/redis/redis.sock', 'port' => 0, 'dbindex' => 0, 'password' => 'secret', 'timeout' => 1.5, ), 同時,官方還推薦加入如下,來用於存儲文件鎖: 'memcache.locking' => '\OC\Memcache\Redis',
========Nextcloud的郵件發信設置========
Nextcloud發送郵件信息的前提:每個用戶(包括管理員)都要事先設置好自己的郵箱地址!
1)使用管理員賬號登陸Nextcloud。點擊右上角的設置圖標里的"管理"-"其他設置"
前提是管理員(admin)要事先設置好自己的郵箱地址。如下設置好郵箱地址后,按Enter鍵后就會顯示一個"對勾"
滿足條件:
1)在admin登陸后的"管理"->"其他設置"的后台里配置好"電子郵件服務器"(配置后可以測試發送郵件是否成功,前提是admin也要事先配置好自己的郵箱地址) 2)各用戶創建並登陸后,要記得配置各自的郵箱地址。比如wangshibo用戶登錄后,配置自己的郵箱地址 3)在分享文件的時候,只要使用對方賬號名進行分享,對方郵箱里就會收到一封分享信息的郵件!
如下,在admin賬號下分享Nextcloud Manual.pdf這個文件給wangshibo用戶
然后登陸wangshibo用戶,就會發現Nextcloud Manual.pdf文件已經分享過來了
登陸wangshibo賬號配置的郵箱,就會發現有上面分享的郵件信
也可以在文件來源方取消分享
==========雲盤上傳文件大小限制==============
nextcloud上傳文件大小的自身限制為512M,如果要想調整這個大小,操作方法如下:
1)修改php.ini上傳文件大小限制 [root@nextcloud ~]# vim /etc/php.ini ...... max_execution_time = 0 #默認是30秒,改為0,表示沒有限制 ...... post_max_size = 10800M #設定 POST 數據所允許的最大大小,如果POST數據尺寸大於post_max_size $_POST 和 $_FILES superglobals 便會為空. ...... upload_max_filesize = 10240M #表示所上傳的文件的最大大小 #另外要說明的是,post_max_size 大於 upload_max_filesize 為佳. 2)修改nginx.conf [root@nextcloud ~]# vim /etc/nginx/conf.d/nextcloud.conf ..... client_max_body_size 10240M; 3)重啟php和nginx服務 [root@nextcloud ~]# systemctl restart php-fpm [root@nextcloud ~]# systemctl restart nginx
==========雲盤創建新用戶==============
碰到一個問題:在admin管理員登錄nextclod,點擊右上角的"用戶",創建新用戶時候,點擊"創建"無反應,即無法在web界面里創建新用戶!
此時可以去數據庫中創建新用戶:
[root@nextcloud ~]# mysql -pnextcloud@123 Welcome to the MariaDB monitor. Commands end with ; or \g.
