六、服务器常用路径

一、Nginx 安装

更新软件源

sudo apt-get update

安装 Nginx

sudo apt-get install nginx

配置 Nginx

1.安装 sysv-rc-con

sudo apt-get install sysv-rc-conf

若未报错即安装成功，若出现以下报错

E: Unable to locate package sysv-rc-conf

打开软件源列表 sources.list 文件

sudo vim /etc/apt/sources.list

按 i 进入insert模式，在文本末尾添加如下内容：

deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse

按键盘 esc 退出输入模式
按 :wq 保存退出

（后续涉及vim命令的操作方式均同上）

更新软件源

sudo apt-get update

重新安装 sysv-rc-con

sudo apt-get install sysv-rc-conf

2.设置 Nginx 开机启动

sudo sysv-rc-conf nginx on

3.允许 Nginx 通过防火墙

sudo ufw status
sudo ufw allow 'Nginx HTTP'

4.启动 Nginx

service nginx start

5.测试 Nginx 服务正常运行
浏览器中输入服务器公网IP，页面显示如下图，即表示 Nginx 配置成功

二、MySQL安装

安装MySQL服务

sudo apt-get install mysql-server

初始无密码进入MySQL

mysql -u root -p

配置MySQL密码

# 查看初识密码策略
SHOW VARIABLES LIKE 'validate_password%';
# 设置密码等级全局参数为LOW
set global validate_password_policy=LOW;
# 设置密码长度为4
set global validate_password_length=4;
# 选择数据库mysql
use mysql;
# 修改root账户的密码为root
update mysql.user set authentication_string=password('root') where user='root' and Host ='localhost';
# 保存信息并退出
update user set plugin="mysql_native_password";
flush privileges;
quit;

三、PHP安装

安装PHP服务

sudo apt-get install php-fpm php-mysql

查看安装的PHP版本号（后续涉及到版本号的地方，需要修改为你当前的PHP版本）

# 进入PHP安装位置
cd /etc/php/
# 查看安装的PHP版本
ls
# 显示 7.2
# 表示我电脑当前安装的PHP版本是 7.2

修改PHP配置文件（注意版本号）

sudo vim /etc/php/7.2/fpm/php.ini

找到773行左右
;cgi.fix_pathinfo=1

修改为

cgi.fix_pathinfo=0

重启PHP服务（注意版本号）

sudo systemctl restart php7.2-fpm

四、配置Nginx

修改nginx配置

第一步

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

修改内容为（注意版本号）：

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

# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# 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.php index.html index.htm index.nginx-debian.html;

server_name server_domain_or_IP;

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;
}

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

第二步

sudo vim /etc/nginx/conf.d/default.conf

输入以下内容：

server {
listen       80;
root         /usr/share/nginx/html;
server_name  localhost;

#charset koi8-r;
#access_log  /var/log/nginx/log/host.access.log  main;

location / {

index index.php index.html index.htm;

}

#error_page  404              /404.html;

#redirect server error pages to the static page /50x.html#
error_page   500 502 503 504  /50x.html;
location = /50x.html {

root   /usr/share/nginx/html;

}

#pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000#
location ~ .php$ {

fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
include        fastcgi_params;

}
}
