多个docker镜像部署lnmp开发环境

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，首先需要创建mysqld.conf文件，生产环境的mysql配置需要自行优化，这里囧供开发环境使用。

\[root@basic lnmp\]\# 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  
\[root@basic lnmp\]\#

#### 启动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

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  
MAINTAINER zhujinbing

RUN cp /php-5.6.36/sapi/fpm/php-fpm.conf.in /usr/local/php/etc/php-fpm.conf

RUN sed -i -e 's\\;date.timezone =\\date.timezone = Asia/Shanghai\\g' /usr/local/php/etc/php.ini

RUN mkdir /usr/local/php/log && \\  
cd / && rm -rf php\* && \\  
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

ENV PATH $PATH:/usr/local/php/sbin:/usr/local/php/bin  
\#COPY php.ini /usr/local/php/etc/  
\#COPY php-fpm.conf /usr/local/php/etc/  
WORKDIR /usr/local/php  
EXPOSE 9000  
CMD \["/usr/local/php/sbin/php-fpm"\]  
\[root@basic lnmp\]\#

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。  
curl -L "[https://www.php.net/distributions/php-5.6.36.tar.gz][https_www.php.net_distributions_php-5.6.36.tar.gz]" -o php-5.6.36.tar.gz

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：  
![多个docker镜像部署lnmp开发环境][docker_lnmp 1]

#### 启动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 ###

这里采用官方nginx:1.15.11来启动。  
先在宿主机创建 /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;  
\}  
\}  
\[root@basic lnmp\]\#

#### 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。

\[root@basic lnmp\]\# 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";  
\}  
\}  
?>
