Install PHP 7, Apache, MySQL 5.6 on CentOS / RHEL 7.1 & 6.7 + Wordpress
最近做了个小项目,挣了几百块钱,于是买了个域名:shawshining.com 和一个搬瓦工的服务器。搬瓦工自带CentOS6,支持一键安装ss,比较方便。买的搬瓦工的服务器只有500MB内存,导致出现一些以前在类似阿里云的学生机1g内存上根本不会出现的问题。所以有必要告诉后来人怎么填坑。事不宜迟,写个教程让大家少走点弯路。如果有问题,清查看最下面的问题解决方法。如果问题依然没有解决可以google,百度一下!主要参考:https://tecadmin.net/install-php-7-apache-2-4-mysql-on-centos-rhel/#

Wordpress安装
安装之前,先创建一个数据库,创建一个用户,并设定其密码。WordPress的安装需要用到这个数据库,并且需要你输入用户名和密码。

把文件下载好解压上传到/var/www/html目录
直接打开你的服务器ip地址,就能打开安装向导,一步步进行即可。
如果提示无法生成wp-config.php文件,可以复制它自动生成好的代码,使用ftp连接,自己上传该文件。
如果你遇到忽然页面变成了白色的话,那么恭喜你!你中招了,请查看问题解决方法。
问题解决方法:
我遇到的问题的根本原因全部都是因为内存只有512MB完全不够用。问题表征主要有:
1.各种服务无法启动。
2.WordPress安装时页面空白。

/etc
php.ini
memory_limit = 256M
