环境准备

[root@docker ~]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)
[root@docker ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:           1.8G        209M        517M        8.9M        1.1G        1.3G
Swap:          1.0G          0B        1.0G
[root@docker ~]# hostname -I
10.0.0.250 172.16.1.250
systemctl disable firewalld.service
systemctl stop firewalld.service
iptables -F

安装yum-utils，它提供yum-config-manager实用程序

yum install -y yum-utils

添加稳定版本库

yum-config-manager 
    --add-repo 
    https://download.docker.com/linux/centos/docker-ce.repo	

更新yum包索引

yum makecache fast

安装Docker社区版

yum install docker-ce -y

启动docker守护进程

systemctl enable docker
systemctl start docker
systemctl status docker

测试，，，网络延时问题可能会导致测试不成功，多测两次

docker run hello-world

查看镜像

c7是下面要用来启动容器的镜像，在centos镜像的基础上安装了常用软件包。

[root@docker ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
c7                  latest              8af948261786        2 days ago          476 MB
centos              latest              a8493f5f50ff        6 weeks ago         192 MB

这里需要一些相关的软件包和配置文件，这里给大家提供了链接：http://pan.baidu.com/s/1eR8vdXg 密码：l1sj

创建web01

docker run --network=host -itd  --name=web01 -h web01 c7
docker attach web01

使用提供的软件包安装nginx

#nginx
yum localinstall -y  nginx-1.10.2-1.x86_64.rpm

nginx配置文件

cd /application/nginx/conf/

[root@web01 conf]# cat nginx.conf

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
include extra/blog.conf;
}

[root@web01 conf]# mkdir extra
[root@web01 extra]# ls
blog.conf

上传wordpress到站点根目录

[root@web01 extra]# cd /application/nginx/html/
[root@web01 html]# wget https://cn.wordpress.org/wordpress-4.7.4-zh_CN.tar.gz
[root@web01 html]# tar xf wordpress-4.7.4-zh_CN.tar.gz
[root@web01 html]# chown -R www.www /application/nginx/html

启动nginx,安装php并启动

/application/nginx/sbin/nginx
chmod +x /etc/rc.local
echo "/application/nginx/sbin/nginx" >> /etc/rc.local

#php
yum localinstall libiconv-devel-1.15-1.x86_64.rpm php-5.5.32-1.x86_64.rpm -y
/application/php/sbin/php-fpm
chmod +x /etc/rc.local
echo "/application/php/sbin/php-fpm" >> /etc/rc.local

创建数据库容器

docker run --network=host -itd  --name=db01 -h db01 c7
docker attach db01

安装并启动数据库

yum -y install mariadb mariadb-server
 mysql_install_db --user=mysql
 mysqld_safe    &>/dev/null &
/usr/bin/mysqladmin -u root password '123456'
mysql -uroot -p123456

创建wordpress库和授权帐户

create database wordpress;
grant all on wordpress.* to 'wordpress'@'localhost' identified by '123456';
grant all on wordpress.* to wordpress@'172.16.1.250' identified by '123456';
