Docker CentOS镜像安装php7

①安装docker并配置完docker加速后

依次输入以下：

docker pull centos:centos7
docker images
docker run -t -i centos:centos7 /bin/bash 

②在进入CentOs7之后先安装wget

yum -y install wget

③然后解决CentOs yum解决下载速度慢 更换下载源

cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.back   /*备份或者改名*/
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 
yum makecache /*生成缓存*/

④处理wget下载速度过慢

wget http://jaist.dl.sourceforge.net/project/kmphpfm/mwget/0.1/mwget_0.1.0.orig.tar.bz2
yum install bzip2 gcc-c++ openssl-devel intltool -y
bzip2 -d mwget_0.1.0.orig.tar.bz2
tar -xvf mwget_0.1.0.orig.tar 
cd mwget_0.1.0.orig
./configure 
make
make install　　

⑤下载安装php环境

yum install epel-release
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
systemctl enable php-fpm.service
systemctl start php-fpm.service
yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel 

最后执行

php -v
