与其说是lnmp环境，还不如说是3个docker环境的mysql、php和nginx镜像。下面我们将以依次按照mysql、php和nginx镜像的顺序描述它们的搭建过程：
环境要求：
docker-compose
docker-ce
centos7 2CPU 4Gb 50G
1、mysql
这里采用官方mysql:5.7的镜像
启动mysql的容器
docker run --name lnmp_mysql -p 3306:3306 --privileged=true -v /data/mysql/data:/var/lib/mysql -v /data/mysql/conf:/etc/mysql/mysql.conf.d -e MYSQL_ROOT_PASSWORD=root -d 10.0.2.10/library/mysql:5.7
说明：10.0.2.10/library/mysql:5.7 这个镜像其实和 mysql:5.7官方的一样，只是将他打了个tag push到自己的harbor仓库永久保存，方便下载使用。
2、php
这里采用Dockerfile的模式，基于centos:7的官方镜像制作，直接上Dockerfile-php文件：
[root@basic lnmp]# cat Dockerfile-php
From centos:7

[root@basic lnmp]#
php-5.6.36.tar.gz文件自行从官网php.net下载，放到dockfile-php同一级目录。
根据dockerfile-php文件制作自己的镜像文件：
docker build -t 10.0.2.10/library/php:5.6.36 -f Dockerfile-php .
看到后面Successfully说明镜像制作成功：
下面我们看一下刚刚制作的镜像：
启动php的容器：
docker run --name lnmp_php --link=lnmp_mysql:lnmp_mysql -d -v /root/lnmp/wwwroot:/home/wwwroot -v /root/lnmp/wwwlogs:/home/wwwlogs -v /root/lnmp/tmp:/tmp -v /etc/localtime:/etc/localtime --privileged=true 10.0.2.10/library/php:5.6.36
3、nginx
这里采用官方nginx:1.15.11来启动
启动nginx容器
docker run \
--name lnmp_nginx \
--link=lnmp_php:phpfpm \
--link=lnmp_mysql:mysql \
-d -p 8088:80 \
-v /root/lnmp/wwwroot:/home/wwwroot \
-v /root/lnmp/nginx_conf:/etc/nginx/conf.d \
-v /root/lnmp/wwwlogs:/home/wwwlogs \
10.0.2.10/library/nginx:1.15.11
说明：10.0.2.10/library/nginx:1.15.11 这个镜像其实和官方 nginx:1.15.11的一样，只是将他打了个tag push到自己的harbor仓库永久保存，方便下载使用。
附上 /root/lnmp/nginx_conf/default.conf配置文件：
[root@basic lnmp]# cat /root/lnmp/nginx_conf/default.conf |grep -v ^#|grep -v ^$
server {
listen 80;
server_name localhost;
access_log /home/wwwlogs/access.log main;
location / {
root /home/wwwroot;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ .php$ {
root /home/wwwroot;
fastcgi_pass phpfpm:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
[root@basic lnmp]#
测试验收
1、静态页面测试
[root@basic lnmp]# cat wwwroot/index.html
hello php
2、php动态页面测试
[root@basic lnmp]# cat wwwroot/index.php
<?php
echo "hello php";
phpinfo();
?>
3、数据库连接测试
[root@basic lnmp]# cat wwwroot/index.php
<?php
echo "hello php";
phpinfo();
?>
[root@basic lnmp]# cat wwwroot/mysql.php
<form action="" method="post">
<select name="host">
<option value="localhost" selected>localhost</option>
<option value="127.0.0.1">127.0.0.1</option>
<option value="lnmp_mysql">lnmp_mysql</option>
</select>
<br><br>
user:<input type="text" name="user" value=""><br><br>
pwd :<input type="password" name="pwd" value=""><br><br>
<input type="submit" value="connent">
<input type="reset" value="reset">
</form>
<?php
error_reporting(~E_ALL);
$host = $_POST['host'];
$user = $_POST['user'];
$pwd = $_POST['pwd'];
if(isset($_POST['host']) && isset($_POST['user']) && isset($_POST['pwd'])){
if(strlen($host)<1 or strlen($user)<1 or strlen($pwd)<1){
echo "请完善数据库链接信息";
exit(0);
}
$conn = mysql_connect($host, $user, $pwd) or die("Error数据库连接失败");
if($conn){
echo "OK数据库连接成功";
}
}
?>
