安装版本：mysql8.0.16-php7.2.16 -nginx1.16

nginx安装

安装Nginx源

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

安装nginx

yum install -y nginx

启动nginx并设置开机自动运行

systemctl start nginx  #启动,restart-重启,stop-停止
systemctl enable nginx #开机启动

安装PHP

安装源

 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

搜索是否存在PHP72w

yum search php72w

3.安装所需扩展

yum install php72w.x86_64 php72w-fpm.x86_64 php72w-cli.x86_64 php72w-common.x86_64 php72w-gd.x86_64 php72w-ldap.x86_64 php72w-mbstring.x86_64 php72w-mcrypt.x86_64 php72w-mysql.x86_64 php72w-pdo.x86_64 php72w-pecl-redis.x86_64 php72w-devel php72w-pear

启动php并设为开机启动

 systemctl start php-fpm #启动,restart-重启，stop-停止
 
 systemctl enable php-fpm #开机启动

配置nginx监听php-fpm

copy 一份/etc/nginx/conf.d/default.conf 文件

cp default.conf my.conf

修改my.conf配置如下

 location / {
        root   /data;
        index  index.php index.html index.htm;
    }

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

配置过程中遇到的报错

2019/05/03 12:20:12 [error] 2600#2600: *5 "/data/index.php" is forbidden (13: Permission denied), client: 10.0.2.2, server: my.nginx.cn, request: "GET / HTTP/1.1", host: "my.nginx.cn"
Connection closing...Socket close.

百度得到解决方案：具体原因就是服务器的SELinux设置为了开启(enabled)状态。

#直接行下面的命令：

setenforce 0

#这种方法我没有尝试，不知道有效性。
vim /etc/selinux/config

#将配置文件中的SELINUX=enforcing修改为SELINUX=disabled即可，修改完成后需要重启下机器。

#这种方法应该是有效的，至少在我的机器中是通过该方式解决了问题。
