安装docker

1
yum update

安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

1
yum install -y yum-utils device-mapper-persistent-data lvm2

设置yum源

1
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

可以查看所有仓库中所有docker版本，并选择特定版本安装

1
yum list docker-ce --showduplicates | sort -r

安装指定版本或者最新版本

1
yum install docker-ce-17.12.1.ce

或者

1
yum install docker-ce

启动Docker，命令：systemctl start docker，然后加入开机启动，如下

1
2
systemctl start docker
systemctl enable docker

EXPOSE 9501

以上面Dockerfile创建一个myeasyswooletest镜像

1
docker build -t myeasyswooletest .

安装完毕后,新建一个容器

1
docker run --name=mytest -ti -p 9501:9501 myeasyswooletest

-ti 启动容器后直接进入容器终端
-p 容器端口映射到外部端口

此时发现容器根目录中存在easyswoole项目目录，为了方便开发，需要做目录映射，由于直接映射会覆盖掉容器中对应目录的内容，需要在宿主机安装easyswoole再进行映射，因此这里先将容器中项目目录拷贝出来，再重新创建容器并映射目录

拷贝文件目录到宿主机中

1
2
docker cp {dockerId}:/easyswoole /www/wwwroot/myeasyswoolestest

关闭并删除容器

1
2
3
docker stop {dockerId}

docker rm {dockerId}

启动容器并映射目录

1
docker run -ti -p 9501:9501 --restart=always  -v /www/wwwroot/myeasyswooletest:/easyswoole myeasyswooletest7

-t:在新容器内指定一个伪终端或终端。

-i:允许你对容器内的标准输入 (STDIN) 进行交互。

-d:让容器在后台运行。

-P:将容器内部使用的网络端口映射到我们使用的主机上。

-p : 是容器内部端口绑定到指定的主机端口

-v：参数用于数据卷映射，/home/vpaas 是宿主机卷标，/usr/local/vpaas_file 是容器卷标

–name: 容器名称

vpaas:latest： 创建的镜像名

数据卷的作用：

docker 镜像启动的容器和宿主机可以看成两个不同的Linux系统，这两个文件系统之间传输文件就是用数据卷进行传输的。

宿主机将文件放入到 /home/vpaas 中，通过容器卷标 /usr/local/vpaas_file 就可以看到放入的文件，类似于文件夹共享。

进入容器

1
docker exec -it {dockerId} /bin/bash

在容器内安装—为了word转pdf

1
2
3
yum install -y libreoffice 
yum install -y unoconv
yum install -y ImageMagick

通过容器生成镜像

1
docker commit -m "安装word转pdf的依赖" {dockerId} newserver

-m:提交的描述信息

-a: 指定镜像作者

e218edb10161：容器ID

newserver: 指定要创建的目标镜像名

重新新建容器

1
docker run -ti -p 9501:9501 --restart=always  -v /www/wwwroot/myeasyswooletest:/easyswoole newserver

拷贝一个docx文件到容器内试试

1
docker cp /www/kkjj.docx {dockerId}:/www/

转换一下

1
soffice --headless --invisible --convert-to pdf kkjj.docx --outdir ./

发现有乱码（不支持中文）

将本地的中文字体放到一起，一起拷贝过去

1
docker cp /usr/share/fonts/chinese ae4c6f7a8b6d:/usr/share/fonts

中文可以显示了

将pdf转图片

1
convert  kkjj.pdf -resize 500% -quality 100 -sharpen 0x1.0 kkjj.png

将镜像发布出去

1
docker login
1
docker images

重命名镜像tag

1
docker tag 94998885c9d4 hottredpen/newserver

推送到自己的仓库

1
docker push hottredpen/newserver

推送太慢，就打包到本地

1
docker save -o pdf.tar pdfserver1.4

另一台机器上安装本地包

1
docker load < pdf.tar

##其他

pfdi添加中文字体

1
https://github.com/DCgithub21/cd_FPDF/blob/master/chinese.php

新增一个PDFChinese.php
