Nextcloud私有云盤在Centos7下的部署筆記

 

搭建我的雲存儲通常會想到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。初一看以爲「口氣」不小,剛推出來就從新「定義」了Cloud,真正試用事後就由衷地贊同這個Nextcloud:它是我的雲存儲服務的絕佳選擇。能夠說Nextcloud 是一款自由 (開源) 的類 Dropbox 軟件,由 ownCloud 分支演化造成。它使用 PHP 和 JavaScript 編寫,支持多種數據庫系統,好比 MySQL/MariaDB、PostgreSQL、Oracle 數據庫和 SQLite。它可使你的桌面系統和雲服務器中的文件保持同步,Nextcloud 爲 Windows、Linux、Mac、安卓以及蘋果手機都提供了客戶端支持。同時,Nextcloud 也並不是只是 Dropbox 的克隆,它還提供了不少附加特性,如日曆、聯繫人、計劃任務以及流媒體 Ampache。php

與ownCloud相比,Nextcloud的功能絲毫沒有減弱,甚至因爲能夠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至關地詳細,幾乎任何關於Nextcloud的問題均可以找到答案,這說明Nextcloud開發團隊確實比ownCloud更加優秀。css

一開始覺得Nextcloud只是一個網盤雲存儲,後來看到Nextcloud內置了Office文檔、圖片相冊、日曆聯繫人、兩步驗證、文件管理、RSS閱讀等豐富的應用,我發現Nextcloud已經僅僅能夠用做我的或者團隊存儲與共享,還能夠打形成爲一個我的辦公平臺,幾乎至關於一個我的的Dropbox了。html

如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,而且會經過 Nginx 和 PHP7-FPM 來運行 Nextcloud,同時使用 MariaDB 作爲數據庫系統。Nextcloud雲盤環境部署後,能夠實現web網頁端、手機移動端和桌面客戶端三者數據同步,其中桌面客戶端能夠在本地設置一個文件夾,用於同步數據,這樣也就至關於在本地備份了數據。同時客戶端只要設置開機啓動,即只要是啓動狀態中,它和網頁端的數據就是自動同步的。廢話很少說了,直接看部署筆記:node

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)
   
1、安裝並配置Nginx和php-fpm
================================================================
將自帶的epel、nginx、php所有卸載(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,首先要爲CentOS添加epel源:
[root@nextcloud-server ~]# yum -y install epel-release
[root@nextcloud-server ~]# yum -y install nginx
   
須要再添加一個yum源來安裝php-fpm,可使用webtatic(這個yum源對國內網絡來講恐怕有些慢,固然你也能夠選擇其它的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
 
完成後,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                                   //將用戶和組都改成nginx
group = nginx
.....
listen = 127.0.0.1:9000                        //php-fpm所監聽的端口爲9000
......
env[HOSTNAME] = $HOSTNAME                     //去掉下面幾行註釋
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp
   
在/var/lib目錄下爲session路徑建立一個新的文件夾,並將用戶名和組設爲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/
   
啓動Nginx和php-fpm服務,並添加開機啓動
[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
   
2、安裝並配置MariaDB
使用MaraiDB做爲Nextcloud數據庫。yum安裝MaraiDB服務
[root@nextcloud-server ~]# yum -y install mariadb mariadb-server
   
啓動MariaDB服務並添加開機啓動
[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,密碼默認爲空,直接回車便可
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
==============================================================================================
或者採用另外一種修改密碼的方式:跳過受權表
1)在/etc/my.cnf文件裏添加"skip-grant-tables"
2)重啓mariadb服務
3)無密碼登錄mariadb,而後重置mysql密碼
MariaDB [(none)]> update mysql.user set password=password("kevin@123") where user="root";
4)去掉/etc/my.cnf文件裏的"skip-grant-tables"內容
5)重啓mariadb服務
6)這樣就可使用上面重置的新密碼kevin@123登錄mariadb了
==============================================================================================
   
設置完MariaDB的密碼後,使用命令行登陸MariaDB,併爲Nextcloud建立相應的用戶和數據庫。
例如數據庫爲nextcloud_db,用戶爲nextclouduser,密碼爲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;
   
3、爲Nextcloud生成自簽名SSL證書
爲SSL證書建立一個新的文件夾:
[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                                                  
   
而後將證書文件的權限設置爲660
[root@nextcloud-server cert]# chmod 700 /etc/nginx/cert
[root@nextcloud-server cert]# chmod 600 /etc/nginx/cert/*
   
4、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,併爲Nextcloud建立data目錄,將Nextcloud的用戶和組修改成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
   
5、設置Nginx虛擬主機
進入Nginx的虛擬主機配置文件所在目錄並建立一個新的虛擬主機配置(記得修改兩個server_name爲本身的域名):
[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;
    
    ssl_certificate /etc/nginx/cert/nextcloud.crt;
    ssl_certificate_key /etc/nginx/cert/nextcloud.key;
    
    # Add headers to serve security related headers
    # Before enabling Strict-Transport-Security headers please read into this
    # topic first.
    add_header Strict-Transport-Security "max-age=15768000;
    includeSubDomains; preload;";
    add_header X-Content-Type-Options nosniff;
    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Robots-Tag none;
    add_header X-Download-Options noopen;
    add_header X-Permitted-Cross-Domain-Policies none;
    
    # Path to the root of your installation
    root /usr/share/nginx/html/nextcloud/;
    
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }
    
    # The following 2 rules are only needed for the user_webfinger app.
    # Uncomment it if you're planning to use this app.
    #rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
    #rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json
    # last;
    
    location = /.well-known/carddav {
      return 301 $scheme://$host/remote.php/dav;
    }
    location = /.well-known/caldav {
      return 301 $scheme://$host/remote.php/dav;
    }
    
    # set max upload size
    client_max_body_size 512M;
    fastcgi_buffers 64 4K;
    
    # Disable gzip to avoid the removal of the ETag header
    gzip off;
    
    # Uncomment if your server is build with the ngx_pagespeed module
    # This module is currently not supported.
    #pagespeed off;
    
    error_page 403 /core/templates/403.php;
    error_page 404 /core/templates/404.php;
    
    location / {
        rewrite ^ /index.php$uri;
    }
    
    location ~ ^/(?:build|tests|config|lib|3rdparty|templates|data)/ {
        deny all;
    }
    location ~ ^/(?:\.|autotest|occ|issue|indie|db_|console) {
        deny all;
    }
    
    location ~ ^/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|ocs-provider/.+|core/templates/40[34])\.php(?:$|/) {
        include fastcgi_params;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param HTTPS on;
        #Avoid sending the security headers twice
        fastcgi_param modHeadersAvailable true;
        fastcgi_param front_controller_active true;
        fastcgi_pass php-handler;
        fastcgi_intercept_errors on;
        fastcgi_request_buffering off;
    }
    
    location ~ ^/(?:updater|ocs-provider)(?:$|/) {
        try_files $uri/ =404;
        index index.php;
    }
    
    # Adding the cache control header for js and css files
    # Make sure it is BELOW the PHP block
    location ~* \.(?:css|js)$ {
        try_files $uri /index.php$uri$is_args$args;
        add_header Cache-Control "public, max-age=7200";
        # Add headers to serve security related headers (It is intended to
        # have those duplicated to the ones above)
        # Before enabling Strict-Transport-Security headers please read into
        # this topic first.
        add_header Strict-Transport-Security "max-age=15768000;includeSubDomains; preload;";
        add_header X-Content-Type-Options nosniff;
        add_header X-Frame-Options "SAMEORIGIN";
        add_header X-XSS-Protection "1; mode=block";
        add_header X-Robots-Tag none;
        add_header X-Download-Options noopen;
        add_header X-Permitted-Cross-Domain-Policies none;
        # Optional: Don't log access to assets
        access_log off;
    }
    
    location ~* \.(?:svg|gif|png|html|ttf|woff|ico|jpg|jpeg)$ {
        try_files $uri /index.php$uri$is_args$args;
        # Optional: Don't log access to other assets
        access_log off;
    }
}
   
接下來測試如下配置文件是否有錯誤,確保沒有問題後重啓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
   
6、爲Nextcloud設置Firewalld防火牆和SELinux
能夠選擇關閉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
   
若是打開了防火牆,則須要設置Firewalld和SELinux
首先須要安裝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,爲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
   
7、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,安裝提示安裝便可!)

==================NextCloud安全與性能優化==================python

這種提示通常在NextCloud的服務器管理中能夠看到,建議緩存類的直接安裝一個便可,安裝多了也沒有什麼用。
爲了Nextcloud服務的安全和性能, 請將全部設置配置正確. 

PHP 模塊 ‘fileinfo’ 缺失. 咱們強烈建議啓用此模塊以便在 MIME 類型檢測時得到最準確的結果.
HTTP 請求頭 「Strict-Transport-Security」 沒有配置爲至少 「15552000」 秒. 出於加強安全性考慮, 推薦按照安全提示中的說明啓用HSTS.

內存緩存未配置. 若是可用, 須要配置 memcache 以加強性能.
PHP 的組件 OPcache 沒有正確配置. 爲了提供更好的性能, 咱們建議在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=============mysql

修改nextcloud程序目錄下的config目錄中的config.php文件,在配置文件中添加以下,這個是多個Memcached實例,單個本身改:
 
'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==================linux

在nextcloud的config配置文件中添加以下,這個是經過TCP鏈接的:
'memcache.local' => '\OC\Memcache\Redis',
'redis' => array(
     'host' => 'localhost',
     'port' => 6379,
      ),

還有性能更好的UNIX鏈接:
'memcache.local' => '\OC\Memcache\Redis',
'redis' => array(
     'host' => '/var/run/redis/redis.sock',
     'port' => 0,
     'dbindex' => 0,
     'password' => 'secret',
     'timeout' => 1.5,
      ),

同時,官方還推薦加入以下,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:每一個用戶(包括管理員)都要事先設置好本身的郵箱地址!
1)使用管理員帳號登錄Nextcloud。點擊右上角的設置圖標裏的"管理"-"其餘設置"nginx

前提是管理員(admin)要事先設置好本身的郵箱地址。以下設置好郵箱地址後,按Enter鍵後就會顯示一個"對勾"web

知足條件:ajax

1)在admin登錄後的"管理"->"其餘設置"的後臺裏配置好"電子郵件服務器"(配置後能夠測試發送郵件是否成功,前提是admin也要事先配置好本身的郵箱地址)
2)各用戶建立並登錄後,要記得配置各自的郵箱地址。好比wangshibo用戶登陸後,配置本身的郵箱地址
3)在分享文件的時候,只要使用對方帳號名進行分享,對方郵箱裏就會收到一封分享信息的郵件!

以下,在admin帳號下分享Nextcloud Manual.pdf這個文件給wangshibo用戶

而後登錄wangshibo用戶,就會發現Nextcloud Manual.pdf文件已經分享過來了

登錄wangshibo帳號配置的郵箱,就會發現有上面分享的郵件信

也能夠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爲512M,若是要想調整這個大小,操做方法以下:

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,改成0,表示沒有限制
......
post_max_size = 10800M    #設定 POST 數據所容許的最大大小,若是POST數據尺寸大於post_max_size $_POST 和 $_FILES superglobals 便會爲空.
......
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 爲佳.

2)修改nginx.conf
[root@nextcloud ~]# vim /etc/nginx/conf.d/nextcloud.conf
.....
client_max_body_size 10240M;

3)重啓php和nginx服務
[root@nextcloud ~]# systemctl restart php-fpm
[root@nextcloud ~]# systemctl restart nginx

==========雲盤建立新用戶==============
碰到一個問題:在admin管理員登陸nextclod,點擊右上角的"用戶",建立新用戶時候,點擊"建立"無反應,即沒法在web界面裏建立新用戶!
此時能夠去數據庫中建立新用戶:

[root@nextcloud ~]# mysql -pnextcloud@123

添加新用戶"wangshibo",密碼爲"wangshibo@123"
MariaDB [nextcloud_db]> insert into oc_users(uid,password) valuses("wangshibo","wangshibo@123");

再次查看:
MariaDB [nextcloud_db]> select * from oc_users;

發如今數據庫中建立的新用戶的密碼是明文保存的。

接着用admin管理員登陸nextcloud,點擊右上角"用戶",就能看到上面在數據庫中新建立的wangshibo用戶了,而後在這裏重置密碼!
(重置密碼時,輸入新密碼,而後按"Enter"鍵回車便可),最後確保用新重置的密碼登陸wangshibo帳號的雲盤。

wangshibo帳號登陸成功後,再登陸數據庫發現,該用戶的密碼就會密文保存了!

========================================================================
建立用戶組的正確方法:
點擊右上角"用戶",在"分組"->"添加分組"。

也能夠登陸數據庫裏建立:
MariaDB [nextcloud_db]> select * from oc_groups;
MariaDB [nextcloud_db]> insert into oc_groups values("運維組");

能夠將新用戶分組到對應的組內,也能夠禁用或刪除用戶。
點擊左下角的"設置",能夠顯示用戶的存儲目錄,郵件地址等。
