ubuntu16.04安装nginx，mysql，php

安装nginx

$ sudo apt-get update
$ sudo apt-get install nginx

ubuntu 安装nginx，默认配置如下

 #location ~ \.php$ {
        #       include snippets/fastcgi-php.conf;
        #
        #       # With php7.0-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php7.0-fpm:
        #       fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        #}

安装mysql

$ sudo apt-get install mysql-server

To secure the installation, we can run a simple security script that will ask whether we want to modify some insecure defaults. Begin the script by typing:

$ mysql_secure_installation

注意：此步是做一些安全配置，可以不执行。比如VALIDATE PASSWORD PLUGIN，设置密码复杂度等。

默认启动监听是127.0.0.1地址。可以注释掉

# vim /etc/mysql/mysql.conf.d/mysqld.cnf
    #bind-address           = 127.0.0.1

安装PHP

$ sudo apt-get install php-fpm php-mysql

默认安装是PHP7.0版本，此版本cgi.fix_pathinfo已发现有漏洞。需更改配置

$ sudo vim /etc/php/7.0/fpm/php.ini
找到cgi.fix_pathinfo此行
更改为cgi.fix_pathinfo=0
然后重启php
$ sudo systemctl restart php7.0-fpm

php-fpm 启动默认是监听socket文件，链接PHP也只能通过sock文件链接。需要更改为端口

找到/etc/php/7.0/fpm/pool.d/www.conf

;listen = /run/php/php7.0-fpm.sock
listen = 127.0.0.1:9000

配置nginx链接PHP

$ vim /etc/nginx/conf.d/test.conf

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;

    server_name server_domain_or_IP;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass 127.0.0.1:9000;
    }
}

$ nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
$ nginx -s reload

编辑/var/www/html/info.php

<?php
phpinfo();
?>

访问http://ip:port/info.php
