一键化部署docker-ce容器化lnmp运行wordpress
前言
这段时间潜心研究docker，想写点东西出来，最后写了个容器话运行的wordpress。
镜像还有脚本我打包了，挂在我的服务器上面，有时间的可以下载下来玩一下。
docker
我把打包的文件放在了服务器上，下载速度可能有点慢。
wget http://www.seeit.life/tools/lnmp.tar #这个是镜像包还有启动脚本
wget http://www.seeit.life/tools/startlnmp.sh #这是解压镜像还有启动tar包里面的启动脚本全程自动化哦，只有最后的你要自己设置帐号密码。
只要
bash startlnmp.shdockerfile
下面我把dockerfile文件放出来，并且还有用到了哪些文件。
[ root@node3 ~/lnmp ]# ls
fpm mariadb nginx[ root@node3 ~/lnmp ]# cd fpm/
[ root@node3 ~/lnmp/fpm ]# ls
CentOS-Base.repo Dockerfile epel.repoCentos-Base.repo epel.repo文件我把里面的地址改成了自己的私有仓库速度会快一点。
不改也没关系的。

rm -rf /var/cache/yum/*;

#!/bin/bash
#
/usr/libexec/mariadb-prepare-db-dir
/usr/bin/mysqld_safe --basedir=/usr 因为要修改里面的nginx.conf的配置文件反带到9000端口，我写在外面直接覆盖里面的就好了。

}我没有使用docker-compose编排容器写yam文件，比较简单也懒得写了，就集成到了启动脚本上了。
[ root@localhost ~/lnmp ]# ls
docker-lnmp.sh fpmv1.0.tar mariadbv1.0.tar nginxv1.0.tar wordpress-4.7.4-zh_CN.tar.gz三个docker导出的镜像加wordpress的压缩包，还有启动初始化脚本。

基本上东西都放在这里了。
docker容器技术可以大大的减轻很多重复的工作，
一次创建，到处运行。资源弹性化利用…
