nextcloud在centos系统下搭建自己的私有云盘
搭建一套自己的私有云盘，让数据存储更加方便、可靠。自己搭建的云存储，首先没有什么容量、下载速度的限制，而且本地访问速度很快。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。
自己搭建私有云其实很简单，首先需要一台主机，然后需要选择一个私有云软件（比如ownCloud、nextCloud、seafile）。以下内容将介绍如何在 CentOS 7 服务器中安装和配置Nextcloud，并且会通过 Nginx 和 PHP7-FPM 来运行 Nextcloud，同时使用 MariaDB 数据库系统。具体部署方法如下：
一 . 部署环境的系统是Centos7版本
[root@nextcloud ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
二. 安装并配置Nginx和php-fpm
[root@nextcloud ~]# yum -y install epel-release
[root@nextcloud ~]# yum -y install nginx
添加一个yum源来安装php-fpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
安装相关组件
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 ~]# php -v
PHP 7.0.27 (cli) (built: Jan 14 2018 09:00:22) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
配置php-fpmvim /etc/php-fpm.d/www.conf.....user = nginx //将用户和组都改为nginxgroup = 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:/binenv[TMP] = /tmpenv[TMPDIR] = /tmpenv[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nginxmkdir -p /var/lib/php/sessionchown nginx:nginx -R /var/lib/php/session/ 启动Nginx和php-fpm服务，并添加开机启动systemctl start php-fpmsystemctl start nginxsystemctl enable php-fpmsystemctl enable nginx三. 安装并配置MariaDB 或 mysql使用MaraiDB作为Nextcloud数据库。yum安装MaraiDB服务yum -y install mariadb mariadb-server启动MariaDB服务并添加开机启动systemctl start mariadbsystemctl enable mariadbMariaDB [(none)]> create database nextcloud; MariaDB [(none)]> create user nextcloud@localhost identified by ‘123456‘;MariaDB [(none)]> grant all privileges on nextcloud.* to nextcloud@localhost identified by ‘123456‘;MariaDB [(none)]> flush privileges;四. 配置Nextcloud生成自签名SSL证书
先为SSL证书创建一个新的文件夹：cd /etc/nginx/cert/penssl 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]:lxplwh //公司名Organizational Unit Name (eg, section) []:Technology //部门Common Name (eg, your name or your server‘s hostname) []:lxplwh //CA主机名Email Address []:lxplwh@126.com 然后将证书文件的权限设置为660chmod 700 /etc/nginx/certchmod 600 /etc/nginx/cert/*五. 下载并安装Nextcloudwget https://download.nextcloud.com/server/releases/nextcloud-12.0.4.zipunzip nextcloud-12.0.4.zipmv nextcloud /usr/share/nginx/html/ 并为Nextcloud创建data目录，将Nextcloud的用户和组修改为nginxmkdir -p nextcloud/data/chown nginx:nginx -R nextcloud/ 六. 配置Nginx虚拟主机#user nobody;

确保没有问题后重启Nginx服务[root@nextcloud ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
解析上面nginx中配置的域名nextcloud.lxplwh.com，邦定hosts. 访问http://nextcloud.lxplwh.com进行Nextcloud界面安装.
设置帐号密码，以及数据库的连接信息。如果不报错，即可安装完成，进入。
到此安装完成。
下面进行一些安全与性能优化
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=1opcache.enable_cli=1opcache.interned_strings_buffer=8opcache.max_accelerated_files=10000opcache.memory_consumption=128opcache.save_comments=1opcache.revalidate_freq=1修改程序目录下的config目录中的config.php文件，在配置文件中添加多个Memcached实例，也可以添加一个：
‘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), ),在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
