最好的LNMP配置在0.5G内存的Centos7.0上

服务器配置

Centos7.0+0.5G内存+1CPU

Web服务器配置

PHP 5.4.16 + Nginx 1.6.3+MariaDB 5.5.44

在上面跑了一个shadowsocks和一个wordpress，数据库配置文件使用my-small.cnf,但是MariaDB经常挂掉，所以求一个好的配置。

数据库挂掉后，重启MariaDb

启动

systemctl start mariadb

结果

<code>Job for mariadb.service failed. See 'systemctl status mariadb.service' and 'journalctl -xn' for details.</code>

Run

systemctl status mariadb.service
