Docker容器里部署Apache+PHP+MariaDB+phpMyAdmin

在上一节中我们知道数据库的用户名是root，密码是123456，但是我们还缺少数据库的ip地址，我们使用如下方法获取docker实例的ip地址，是172.17.0.3

[root@test01 ~]# docker ps
CONTAINER ID        IMAGE                      COMMAND             CREATED             STATUS              PORTS                     NAMES
2e78c466919e        liuxin/centos-mariadb:v1   "/root/run.sh"      11 hours ago        Up 3 hours          0.0.0.0:13306->3306/tcp   dreamy_bell
[root@test01 ~]# docker inspect --format ‘{{ .NetworkSettings.IPAddress }}‘ 2e78c466919e
172.17.0.3
[root@test01 ~]# 

[root@test01 ~]# mkdir phpMyAdmin_dockerfile && cd phpMyAdmin_dockerfile
[root@test01 phpMyAdmin_dockerfile]# ls
config.inc.php  Dockerfile  httpd_init.sh  phptest.php  run.sh

内容如下。具体每行的意思已经添加到注释中了

[root@test01 phpMyAdmin_dockerfile]# cat Dockerfile

#添加启动文件
ADD run.sh /root/run.sh
RUN chmod 775 /root/run.sh

#设置默认启动命令
CMD ["/root/run.sh"]

这里我直接将写好的配置文件上传，然后修改文件权限。也可以通过脚本来配置，不过比较麻烦，不如这个简单。改动的配置如下

设置phpmyadmin的登录密码

$cfg[‘blowfish_secret‘] = ‘123456‘; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
设置连接数据库的账号、密码、ip和端口

$cfg[‘Servers‘][$i][‘host‘]          = ‘172.17.0.3‘;    // MySQL hostname or IP address
$cfg[‘Servers‘][$i][‘port‘]          = ‘‘;              // MySQL port - leave blank for default port
$cfg[‘Servers‘][$i][‘user‘]          = ‘root‘;          // MySQL user
$cfg[‘Servers‘][$i][‘password‘]      = ‘123456‘;      // MySQL password (only needed

[root@test01 phpMyAdmin_dockerfile]# cat httpd_init.sh 
#!/bin/sh

sed -i ‘s/#ServerName www.example.com:80/ServerName localhost:80/g‘ /etc/httpd/conf/httpd.conf
sed -i ‘/Require ip/d‘ /etc/httpd/conf.d/phpMyAdmin.conf
sed -i ‘//a Require all granted‘ /etc/httpd/conf.d/phpMyAdmin.conf

[root@test01 phpMyAdmin_dockerfile]# cat phptest.php 
< ?php
phpinfo();
?>

[root@test01 phpMyAdmin_dockerfile]# cat run.sh 
#!/bin/sh

httpd
while true;do sleep 1000;done

[root@test01 phpMyAdmin_dockerfile]# docker build -t liuxin/centos-phpmyadmin:v1 ./

映射，物理机端口8080到容器的80端口

[root@test01 phpMyAdmin_dockerfile]# docker run -d -p 8080:80 liuxin/centos-phpmyadmin:v1 /root/run.sh
