如何在centos7.3系统下安装php7.0

需求：在Centos7.3下搭建LNMP环境

1. 关闭防火墙和selinux 

 打开文件selinux  

vim  /etc/sysconfig/selinux

将文件中SELINUX=enforcing改为disabled，然后执行”setenforce 0″不用重启地关闭selinux。  

SELINUX=disabled

关闭放火墙 systemctl stop firewalld.service  

2.安装软件

2.1.MYSQL安装 

 下载MySQL的repo源 

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

安装mysql-community-release-el7-5.noarch.rpm包 

rpm -ivh mysql-community-release-el7-5.noarch.rpm

安装MYSQL 

 sudo yum install -y  mysql-server

 更改MYSQL用户权限： 

sudo chown -R root:root /var/lib/mysql

 重启服务： 

systemctl restart mysql.service

登录，并修改密码： 

mysql -u root 
mysql > use mysql; 
mysql > update user set password=password(‘123456‘) where user=‘root‘; 
mysql > exit;

2.2nginx安装 下载对应当前系统版本的nginx包 

wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

建立nginx的yum仓库（默认yum是没有nginx的） 

rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

下载并安装nginx yum install -y nginx 

nginx启动 

 systemctl start nginx.service

2.3安装php 

 rpm 安装 Php7 相应的 yum源 

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

安装php7.0

yum install -y php70w

安装PHP扩展 

 yum install -y  php70w-mysql.x86_64   php70w-gd.x86_64   php70w-ldap.x86_64   php70w-mbstring.x86_64  php70w-mcrypt.x86_64

安装php FPM 

 yum install -y php70w-fpm

3. 修改配置文件

3.1修改Nginx配置文件 

 nginx配置文件位置：

（/etc/nginx/conf.d/default.conf） 
 vim /etc/nginx/conf.d/default.conf

 修改 root目录,可自定义： 

 root   /forest/nginxDir/html;

 配置php解析，修改 下面代码中黑色加粗部分：

 location ~.php$ { 
 root   /forest/nginxDir/html; 
 fastcgi_pass 127.0.0.1:9000; 
 fastcgi_index index.php; 
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
 include    fastcgi_params;
 }

3.2 修改php-fpm配置文件 

 php-fpm配置文件位置：（/etc/php-fpm.d/www.conf） 

修改 

user =nginx 
group=nginx

4.放入测试文件 

cd /forest/nginxDir/html
echo 'hello eric' >index.php

5.启动服务

5.1启动nginx服务： 

systemctl start nginx.service

 查看启动状态： 

systemctl status nginx

看到以下字眼说明启动成功！ 

Active: active (running) since 六 2016-11-19 13:40:04 CST; 50min ago

5.2.启动PHP-FPM： 

systemctl start php-fpm.service

 查看启动状态： 

systemctl status php-fpm.service

 看到以下字眼说明启动成功！ 

Active: active (running) since 六 2016-11-19 14:14:33 CST; 18min ago

6.测试 

 在浏览器打开192.168.44.129：80/index.php 看到 hello eric 就大功告成~

设置开机自启动服务

systemctl enable php-fpm.service
systemctl enable nginx.service

如项目框架为lavarel，则配置文件可用下面这个：

server {
   listen  80;
   server_name learn.laravel5.com;
   root /var/www/html/learnlaravel5/public;
   index index.html
   index.php;
   location / {
        try_files $uri $uri/
        /index.php$is_args$query_string;
    }
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME
        $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}
