在 CentOS7上用 yum 搜索 redis, 通常情况下是找不到想要的结果的:

[root@34fd69572161 /]# yum update
[root@34fd69572161 /]# yum search all redis
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile

网上有使用 yum install epel-release添加 Fedora 的 epel 仓库的, 先说结论: **不可行, 是过期攻略. **

如下:

[root@f873fc89b235 /]# yum install epel-release
[root@f873fc89b235 /]# yum update
[root@f873fc89b235 /]# yum info redis

有 redis 了, 不过是非常旧的版本3.2.12, 所以这个仓库应该是没有人维护了, 故该方法不可行

正解如下

使用 remi 仓库

官网地址: Remi’s RPM repository (remirepo.net)

在页面中找到如下部分, 右键 remi-release-8.rpm 复制链接地址即可得到仓库地址

然后执行如下命令 (命令中的网址即上面复制的仓库地址)

yum install https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm -y

yum update -y

使用这个仓库时在 yum 后加上参数 --enablerepo=remi 即可

结果如下:

[root@34fd69572161 /]# yum --enablerepo=remi info redis
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile

 * extras: mirrors.cn99.com

 * remi-safe: mirrors.tuna.tsinghua.edu.cn
 * updates: mirrors.dgut.edu.cn
Available Packages

执行安装

yum --enablerepo=remi install redis -y
