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

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
