Centos6_2">Centos6的一些优势

Centos6的安装镜像仅400M,开机内存使用仅仅110M. 资源使用率极低,1G内存的机器就能跑的飞起.

JDK和Nginx都能正常运行,对一些硬件资源有限的项目,还挺适合的.

Centos6CentOS_Vaultyum_10">为Centos6配置CentOS Vault源—防止yum源过期

参考：https://mirrors.ustc.edu.cn/help/centos.html
CentOS 6系统于2020年11月30日停止维护服务，如有需要继续使用 CentOS6，请使用 CentOS Vault 镜像源。

mkdir -p /etc/yum.repos.d/bak# 备份旧的源文件
mv /etc/yum.repos.d/*.bak /etc/yum.repos.d/bak# 编辑
vi /etc/yum.repos.d/CentOS-Vault.repo

源内容如下:
