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;
}
}
