elementaryos5安装mysql5.7、php7.2、nginx1.14.0

一、mysql5.7

安装mysql5.7：

sudo apt-get install mysql-server-5.7

查看安装的mysql版本：

mysql -V

5.7版本mysql安装过程中以及安装完毕都不会提示设置密码

配置用户名密码：

su mysql

show databases；
use mysql;
update user set authentication_string=PASSWORD("123456") where user='root';
update user set plugin="mysql_native_password";
flush privileges;
quit;

修改完毕，重启mysql：

sudo /etc/init.d/mysql restart或者sudo systemctl restart mysql

二、安装nginx1.14.0：

sudo apt-get install nginx

访问下127.0.0.1看看有没有欢迎界面就行了

三、安装php7.2

sudo apt-get install php7.2-fpm php7.2-mysql

之后可能还需要gd之类的，可以sudo apt-get install php7.2然后按下tab会自动提示

四、配置nginx支持php,要不然访问php就变成了下载文件　　

备份一个先：

sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/default.bak

编辑配置文件

sudo vim /etc/nginx/sites-available/default

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# Default server configuration

server {

# SSL configuration
#

# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.

# Don't use them in a production server!
#
# include snippets/snakeoil.conf;

root /var/www/html;

# Add index.php to the list if you are using PHP
index index.html index.php index.htm index.nginx-debian.html;

server_name _;

location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}

# pass PHP scripts to FastCGI server
#
location ~ \.php$ {

include snippets/fastcgi-php.conf;

# With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
# With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
# listen 80;
# listen [::]:80;
#
# server_name example.com;
#
# root /var/www/example.com;
# index index.html;
#
# location / {
# try_files $uri $uri/ =404;
# }
#}
#

#虚拟主机

server {
listen 8000;
#listen [::]:80;

server_name localhost;

root /home;
index index.html index.php;

location / {
try_files $uri $uri/ =404;
}

# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
include snippets/fastcgi-php.conf;

# With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
# With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# include fastcgi_params;
}
}

其中最重要的就是：如果需要虚拟主机，虚拟主机配置里面也要添加location ~ \.php$ {...

虚拟主机配置项：

sudo vim /etc/nginx/sites-available/default

文件底部添加就行了
