Installing Lumen -- Red Hat/CentOS

＃＃＃＃To install a modern version of PHP on Red Hat and CentOS

I recommend using the Webtatic ( https://webtatic.com/ )　yum repository.

First, add the repository with the Webtatic　release RPM; you should use the repository that matches　your specific version

# CentOS/REHL 7

Adding the Webtatic Repository

$ yum -y update
$ sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

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

Installing PHP Packages from Webtatic

$ yum install
php71w.x86_64
php71w-mysql.x86_64
php71w-mbstring.x86_64
php71w-xml.x86_64
php71w-pecl-xdebug.x86_64

 

install the MySQL client and server

Installing MySQL on REHL

$ sudo yum install mysql-server mysql 

（这里我用的是：

sudo yum install mariadb-server mariadb
执行完后， sudo systemctl status mariadb.service 

）

(备注：　这里犯了个低级错误，　在自己的ubuntu系统里执行sudo yum install mysql-server mysql，　报错如下：

没有已启用的仓库。
执行 "yum repolist all" 查看您拥有的仓库。
您可以用 yum-config-manager --enable <仓库名> 来启用仓库

那么自己就设置仓库（To set up the repository－－－https://webtatic.com/projects/yum-repository/）：

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm，结果报错：
rpm：RPM should not be used directly install RPM packages, use Alien instead!　可笑！！我在ubuntu系统　用rpm安装rpm包，　所以
提示让我转换　rpm为ubuntu能够识别的包。！！

)

Securing the MySQL Installation

Once MySQL is installed, you should set a root password

$sudo  /usr/bin/mysql_secure_installation　　

(备注：sudo: /usr/bin/mysql_secure_installation：找不到命令,原因是： mysql-server没有安装成功

执行完 sudo yum install mariadb-server mariadb，之后就能找到命令了
