↓ 扫一扫 视频在线观看↓

以php7.4为例，其他版本自行替换"php74"。

#创建epel源：

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

#再创建两个repo：

cat >/etc/yum.repos.d/remi-php74.repo<< EOF
[remi-php74]
name=php74 for Enterprise Linux 7 - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/7/php74/x86_64/
failovermethod=priority
enabled=1
gpgcheck=0
EOF

cat >/etc/yum.repos.d/remi-safe.repo<< EOF
[remi-safe]
name=remi-safe for Enterprise Linux 7 - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/7/safe/x86_64/
failovermethod=priority
enabled=1
gpgcheck=0
EOF

#检查一下:
