CentOS7 安装 NextCloud

NextCloud 的安装依赖LAMP环境，即 Linux + Apache + MySQL(Mariadb) + PHP，所以在装 NextCloud前最好先装好这些，并且保证已经可用。

为了方便，本文在运行shell命令时都是以管理员用户身份运行（root权限下运行）！！！

具体步骤：

这里重申一下，为免麻烦，以下命令都是以管理员用户的身份运行的，root权限下执行的！

1. 开放防火墙

setenforce 0
sed -i 's/enforcing/disabled/' /etc/selinux/config
systemctl disable --now firewalld
reboot

2. 安装php 7.2 + apahce 运行环境

yum install centos-release-scl-rh -y
# yum search php 
yum install rh-php72 -y
yum install rh-php72 rh-php72-php rh-php72-php-gd rh-php72-php-mbstring rh-php72-php-intl rh-php72-php-pecl-apcu -y
yum install rh-php72-php-mysqlnd -y
scl -l
scl enable rh-php72 "php -v"
scl enable rh-php72 bash
php -v
php -myum install -y httpd
systemctl start httpd
systemctl enabled httpdln -s /opt/rh/httpd24/root/etc/httpd/conf.d/rh-php72-php.conf /etc/httpd/conf.d/
ln -s /opt/rh/httpd24/root/etc/httpd/conf.modules.d/15-rh-php72-php.conf /etc/httpd/conf.modules.d/
ln -s /opt/rh/httpd24/root/etc/httpd/modules/librh-php72-php7.so /etc/httpd/modules/systemctl restart httpd

3，安装mysql数据库

yum -y install wget gcc gcc-c++ ncurses ncurses-devel cmake numactl.x86_64 libaio
wget http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

登录NextCloud，创建管理员用户，访问：http://192.168.225.194/NextCloud/

【注意！】 图4这步包括以下内容：1. 创建owncloud的管理员用户（Create an admin account）。2. 数据存储文件夹（Data folder）。这里默认文件夹就可以了，不用管。 3. 配置数据库，包括数据库类型的选择，对应的用户、密码、数据库配置。这里默认是SQLite数据库类型，如果要用MySQL或者MariaDB的，这里一定要配置一下。如果忘记配置了，可以参考博文《如何将owncloud的数据库从SQLite迁移到MySQL/MariaDB》迁移数据库。
