基于上一篇：CentOS7.3安装Apache2.4+MySQL5.7+PHP7.1过程记录 的环境基础上，搭建NextCloud进行中，不管是否成功都把过程记录下来先。
一、配置MySQL数据库
# 使用 root 用户登录 MySQL [root@localhost ~]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.22 MySQL Community Server (GPL) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> # 修改 MySQL 配置文件 vim /etc/my.cnf # 修改默认编码为 UTF-8，添加在 [mysqld] 后 character_set_server = utf8 init_connect = 'SET NAMES utf8' # 进入编辑my.cnf配置文件 [root@localhost sgtfz]# vim /etc/my.cnf # 已进入my.cnf配置文件，下面是已经修改好的内容 # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld] character_set_server = utf8 init_connect = 'SET NAMES utf8' # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid # 编辑好之后保存退出 # 使用 root 用户登录 MySQL [root@localhost sgtfz]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.22 MySQL Community Server (GPL) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. # 创建 nextcloud 数据库 mysql> create database nextcloud; Query OK, 1 row affected (0.01 sec) # 创建 nextcloud_user 用户 mysql> create user 'nextcloud_user'@'localhost' identified by '密码'; Query OK, 0 rows affected (0.00 sec) # 给 nextcloud_user 用户授权 nextcloud 数据库的所有权限 mysql> grant all on nextcloud.* to 'nextcloud_user'@'localhost'; Query OK, 0 rows affected (0.00 sec) # 刷新权限（将当前 user 和 privilige 表中的用户信息/权限设置从 mysql 库提取到内存中） mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) # 退出 MySQL mysql> \q
二、部署Nextcloud
# 移动到 Apache 部署目录，这一步我漏了 cd /var/www/html # 下载 Nextcloud 服务端 [root@localhost sgtfz]# wget https://download.nextcloud.com/server/releases/nextcloud-13.0.2.zip --2018-05-28 00:11:58-- https://download.nextcloud.com/server/releases/nextcloud-13.0.2.zip 正在解析主机 download.nextcloud.com (download.nextcloud.com)... 88.198.160.133 正在连接 download.nextcloud.com (download.nextcloud.com)|88.198.160.133|:443... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：61108941 (58M) [application/zip] 正在保存至: “nextcloud-13.0.2.zip” 100%[============================================>] 61,108,941 30.0KB/s 用时 22m 32s 2018-05-28 00:34:32 (44.1 KB/s) - 已保存 “nextcloud-13.0.2.zip” [61108941/61108941]) # 移动已下载好的nextcloud-13.0.2.zip到/var/www/html目录 [root@localhost sgtfz]# mv nextcloud-13.0.2.zip /var/www/html # 转到/var/www/html目录 [root@localhost sgtfz]# cd /var/www/html # 解压nextcloud服务端压缩包 [root@localhost html]# unzip nextcloud-13.0.2.zip # 如果没有解压程序，安装 unzip 解压程序 yum -y install unzip # 赋予目录权限（R: 递归） [root@localhost html]# chmod -R 777 nextcloud # 永久关闭 SELinux（需重启）如果没有关闭SELinux，浏览器访问 IP/nextcloud 会造成“内部服务器错误” [root@localhost html]# sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config # 重启CentOS主机，稍后继续下一步。
没有关闭SELinux的结果如下图：
关闭SELinux，然后重启CentOS服务器主机后，正常了。
按步骤创建管理员账户，点击安装完成
这里我忘了，默认使用的是SQLite作为数据库使用，强烈不推荐。所以我们使用MySQL如下图
1.数据库用户名
2.数据库密码
3.数据库名称
4.数据库地址（数据库的IP，如果是本机，可以写127.0.0.1，也可以写localhost）
最后再点击完成。
稍等片刻，就进入我们的私有云啦！！
接下来怎么使用这个nextcloud私有云，就以后再慢慢去体验与发现了😪
