Ubuntu 18.04 LEMP(Linux+Nginx+Mysql+PHP)環境建立
底下紀錄如何在 Ubuntu 18.04 上建立 LEMP 的環境。 This note demonstrates how to create a LEMP environment on an Ubuntu 18.04 server.
步驟一：安裝 Nginx Web Server (Step One: Installing nginx web server)
Open a console and input the following commands to install nginx.
- sudo apt-get update
- sudo apt-get install nginx
接著查詢主機IP
You can find your server’s public IP address by the following command:
ip addr show eth0 | grep inet | awk ‘{ print $2; }’ | sed ‘s/\/.*$//’
在瀏覽器鍵入 local host ip。 Type the address in your web browser(Google chrome or firefox .etc).
http://server_domain_name_or_IP
若在瀏覽器上看到下圖，表示 nginx 已安裝成功。If you see the below message, your nginx installation is completed.
可看到上圖時，nginx便已經可跑靜態網頁了，預設的html檔案存放位置為 /var/www/html
步驟二：安裝MySql(Step Two: Installing mysql
Open a console and input the following commands to install mysql.
sudo apt-get install mysql-server
安裝完後輸入以下指令進行安全性設定 Type the following command to secure the MySQL installation:
sudo mysql_secure_installation
步驟三：安裝php與設定 php.ini(Step Three: Installing php and configuring the php.ini)
Installing php:
sudo apt-get install php-fpm php-mysql
Modifying php.ini file:
sudo nano /etc/php/7.2/fpm/php.ini
Replace this line:
;cgi.fix_pathinfo=1 with
cgi.fix_pathinfo=0
Save and restart php service:
sudo service php7.2-fpm restart
步驟四：設定Nginx的php模組功能(The PHP Processor configuration for nginx)
建立一個nginx設定
Create the configuration file for nginx:
sudo nano /etc/nginx/sites-available/test.com
Input the below text to the configuration file:
server { listen 80;
root /var/www/html;
index index.php index.html index.htm;
server_name test.com;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
}
location ~ /\.ht {
deny all;
}
}
# Creating a symbolic link to enable the new server block.
sudo ln -s /etc/nginx/sites-available/test.com /etc/nginx/sites-enabled/
# Unlink the default configuration
sudo unlink /etc/nginx/sites-enabled/default
# Checking the new configuration file
sudo nginx -t
# Reload Nginx
sudo service nginx reload
步驟五：建立php測試檔案(Step Five: Create a php file to test)
# Creating the test php file
sudo nano /var/www/html/info.php
Input the following php code into the new file(info.php).
Open your browser to visit this page:
http://your_server_domain_or_IP/info.php
You should see some information about your server:
