與其說是lnmp環境，還不如說是3個docker環境的mysql、php和nginx鏡像。下面我們將以依次按照mysql、php和nginx鏡像的順序描述它們的搭建過程：
環境要求：
docker-compose
docker-ce
centos7 2CPU 4Gb 50G
1、mysql
這裏採用官方mysql:5.7的鏡像，首先需要創建mysqld.conf文件，生產環境的mysql配置需要自行優化，這裏囧供開發環境使用。
[root@basic lnmp]# cat /data/mysql/conf/mysqld.cnf |grep -v ^#|grep -v ^$
[mysql]
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock
[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
max_connections=200
character-set-server=utf8
skip-name-resolve
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M
default-time_zone='+8:00'
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
[root@basic lnmp]#
啓動mysql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
說明：10.0.2.10/library/mysql:5.7 這個鏡像其實和 mysql:5.7官方的一樣，只是將他打了個tag push到自己的harbor倉庫永久保存，方便下載使用。
2、php
這裏採用Dockerfile的模式，基於centos:7的官方鏡像製作，直接上Dockerfile-php文件：
[root@basic lnmp]# cat Dockerfile-php
From centos:7

EXPOSE 9000

[root@basic lnmp]#
php-5.6.36.tar.gz文件自行從官網php.net下載，放到dockfile-php同一級目錄。
curl -L "https://www.php.net/distributions/php-5.6.36.tar.gz" -o php-5.6.36.tar.gz
根據dockerfile-php文件製作自己的鏡像文件：
docker build -t 10.0.2.10/library/php:5.6.36 -f Dockerfile-php .
看到後面Successfully說明鏡像製作成功：
下面我們看一下剛剛製作的鏡像：
啓動php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
這裏採用官方nginx:1.15.11來啓動。
先在宿主機創建 /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]#
啓動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
說明：10.0.2.10/library/nginx:1.15.11 這個鏡像其實和官方 nginx:1.15.11的一樣，只是將他打了個tag push到自己的harbor倉庫永久保存，方便下載使用。
鏡像和容器信息截圖
1、鏡像信息：
2、容器信息：
測試驗收
1、靜態頁面測試
[root@basic lnmp]# cat wwwroot/index.html
hello php
2、php動態頁面測試
[root@basic lnmp]# cat wwwroot/index.php
<?php
echo "hello php";
phpinfo();
?>
3、數據庫連接測試
[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 "請完善數據庫鏈接信息";
exit(0);
}
$conn = mysql_connect($host, $user, $pwd) or die("Error數據庫連接失敗");
if($conn){
echo "OK數據庫連接成功";
}
}
?>
