Centos6配置yum源

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.

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:

[base]
name=CentOS-6.10 - Base - mirrors.aliyun.com
failovermethod=priority	
baseurl=https://mirrors.aliyun.com/centos-vault/6.10/os/$basearch/

结果验证

# 安装vim
yum install -y vim

为Centos6配置epel源

# 手动编辑epel.repo文件
vim /etc/yum.repos.d/epel.repo

• 阿里云的epel源
  https://developer.aliyun.com/mirror/epel?spm=a2c6h.13651102.0.0.3e221b11ILV8ex

# 阿里云的epel源
[epel-aliyun]
name=epel-aliyun-CentOS-$releasever
baseurl=https://mirrors.aliyun.com/epel-archive/$releasever/$basearch/
gpgcheck=0

结果验证

# 从epel源安装htop
yum install -y htop

为Centos6配置ELRepo源—已ELRepo被官方清空

因上游ELRepo源已被官方清空,下游的镜像源内也空了.

# 编辑/etc/yum.repos.d/elrepo.repo
vim /etc/yum.repos.d/elrepo.repo

elrepo.repo具体内容如下:
