CentOS7使用阿里yum源进行升级和安装php70W

切换镜像

1、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

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

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 

3、之后运行yum makecache生成缓存

4. 安装WEBTATIC源

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

提示错误：

error: Failed dependencies:
epel-release >= 7 is needed by webtatic-release-7-3.noarch

安装epel解决上面问题

yum install epel-release -y 

5. 终端再次运行如下命令：

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装php

1. 检查是否有安装php

php -v

如果有安装请先写在

yum remove php common 

2. 检查php包

yum list php70w

3. 安装

yum install php70w

4. 验证php安装

php -v
