VM虚拟机 CentOS7 安装PHP 环境

之前安装过PHP 云服务器环境，但是没有深究，停留在粗浅层次，我记性不好记点东西防止自己遗忘

PHP 服务器安装分两种一种YUM 安装一种编译安装（由于linux机制，每个文件夹都有他指定的含义，不可随意使用，编译安装需要了解，文件夹分类信息，YUM 安装则不需要去考虑，因为他已经帮你固定安装好了目录，这就是网上为什么推荐yum的原因）（文中例子是不必要操作，可了解但不是必须，个人建议理解一下）

YUM安装注意事项

1进入ROOT 权限(虚拟机) su 命令接着输入密码前缀带ROOT 即成功 CD / （切换到根目录，可不用操作怕误导注释出来）

[PCname@localhost ~]$ su

password：

[root@localhost PCname]# cd /

2.更换安装YUM 源

如果默认输入 yum install PHP 这样默认安装的会是5.4的PHP 但是我们现阶段基本上都是5.6 以及PHP7 的版本此时我们就需要更换YUM源。

CentOS 6.x 源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

CentOS 7.x 源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

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

例子：查看该源对应的安装包命令（以PHP 为例）

yum list --enablerepo=webtatic | grep PHP

例子：获得信息如下（截取部分）

[root@localhost /]# yum list --enablerepo=webtatic | grep PHP

emacs-PHP-mode.noarch 1.18.2-1.el7 base

PHP-Metadata.noarch 1.6.0-1.el7 epel

PHP-Monolog.noarch 1.22.0-1.el7 epel

例子：查询5.6版本PHP 命令（也可以查其他软件）

yum search PHP56w

例子：显示结果

[root@localhost yum.repos.d]# yum search PHP56w

2.安装Apache

yum install httpd httpd-devel

启动apache:

/bin/systemctl start httpd.service

此时用浏览器访问你服务器IP地址应该是

这样表示安装成功

笔记：

systemctl stop firewalld.service #停止firewall

systemctl disable firewalld.service #禁止firewall开机启动

firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）

2.安装MysqL:

yum install MysqL MysqL-server

启动MysqL:

systemctl start MysqL.service

如果报错

[root@localhost yum.repos.d]# systemctl start MysqL.service

Failed to start MysqL.service: Unit MysqL.service Failed to load: No such file or directory.

或者

Failed to start MysqLd.service: Unit not found

则安装 mariadb-server

yum install -y mariadb-server

启动服务

systemctl start mariadb.service

添加到开机启动

systemctl enable mariadb.service

//键入命令

[root@localhost /]# systemctl enable mariadb.service

Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

//进入MysqL

[root@localhost /]# MysqL -uroot -p

Enter password:

Welcome to the MariaDB monitor. Commands end with ; or g.

Your MariaDB connection id is 2

Server version: 5.5.60-MariaDB MariaDB Server

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]>

键入EXIT+ 回车退出 MysqL

搞定~

3.安装PHP

yum install PHP56w

重启apache使PHP生效

/bin/systemctl start httpd.service

查看 PHP 版本 PHP -v

[root@localhost /]# PHP -v

PHP 5.6.38 (cli) (built: Sep 15 2018 08:16:33)

进入文件目录

cd / (进入根目录)

cd var/www/html

[root@localhost www]# cd /var/www/html/

[root@localhost html]# touch index.PHP

[root@localhost html]#

此时可以在目录：/var/www/html/下建立一个 PHP 文件index.PHP,加入代码：访问查看PHP 配置文件
