現在容器化技術越來越成熟和流行,比傳統的虛擬化技術確實是有很大的優勢,所以流行是必然的。今天來實踐一把,使用Docker的dockerfile方式定製lnmp環境。
環境配置

Docker 版本:19.03.5
Nginx 版本:1.15.5
PHP 版本:7.2.26

Nginx配置檔案
vim /data/docker/config/nginx/conf.d/default.conf
server {
listen 80;
listen [::]:80;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;
charset utf-8;
server_name zhangdetalk.com www.zhangdetalk.com;
location ~ \.md$ {
default_type 'text/plain';
}
root /var/www/html/zhangdetalk_blog_admin;//專案目錄
location / {
#try_files $uri $uri/ =404;
index index.php index.htm index.html;
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
location ~ \.php$ {
include fastcgi_params;
fastcgi_index index.php;
fastcgi_pass php7:9000;//容器:埠號
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
docker-compose安裝
1. curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
2. chmod +x /usr/local/bin/docker-compose //設定可執行許可權
建立並啟動容器
docker-compose -f docker-compose-linux.yml up -d --force-recreate --remove-orphans
容器檢視
docker ps
測試
vim /data/www/zhangdetalk_blog_admin/index.php
<?php
echo "Hello World";
$conn = mysqli_connect('資料庫容器名字','dbuser','dbpw');
if($conn){
echo '資料庫連線成功!';
}else{
echo '資料庫連線失敗!';
}
phpinfo();
?>
透過訪問站點:http://www.zhangdetalk.com/
可以看到顯示資料庫連線成功,並列印出PHP的相關資訊
到此步,我們的lnmp環境搭建大功告成!
github原始碼

遇到的問題
1、PHP程式碼連線資料庫,host不能寫成127.0.0.1或localhost,需要填寫資料庫容器名字
2、mysql8連線,連線失敗,因為加密方式有變化
解決方式:主機登入mysql,修改成舊的加密方式(mysql_native_password),並重置密碼
* mysql -uroot -p;
* use mysql;
* select host,user,plugin from user;
* alter user 'root'@'%' identified with mysql_native_password by '123456';
