Docker快速搭建（CentOS）

通过Docker方式，可在30分钟内完成整个环境的搭建，方便快捷。

更新系统

sudo yum update -y

安装 Java SDK 8

# yum安装
yum install -y java-1.8.0-openjdk.x86_64

安装 ImageMagick 7.0.11

本应用通过 ImageMagick 生成图形验证码，使用图形验证码前需要先安装 ImageMagick。

# 安装相关依赖
yum install -y gcc gcc-c++ glib2-devel cairo-devel libtool-ltdl-devel tcl-devel libpng-devel libjpeg-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel

# 下载
wget https://imagemagick.org/download/ImageMagick.tar.gz --no-check-certificate

# 解压
tar -xvzf ImageMagick.tar.gz

# 进入解压之后的文件夹
cd /ImageMagick-7.1.0-0

# 执行
./configure --with-modules --enable-shared --with-perl

# 编译
make && make install

# 设置快捷方式
ldconfig /usr/local/lib

# 测试
magick -version

docker部署环境

该docker环境包含mysql、reids、elasticsearch、mongodb、kafka-manager、kakak、zookeeper，对应端口/账号见文末端口汇总

安装/启动docker

# 设置Yum源：
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 执行以下命令，添加docker的yum源
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

# 安装
sudo yum install -y docker-ce

# 启动
sudo systemctl start docker

# 设置开机启动
sudo systemctl enable docker

# 验证是否安装成功
docker run hello-world

# 等待一段时间后出现`Hello from Docker!`就是成功了：

安装docker-compose

# 下载
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 设置权限
sudo chmod +x /usr/local/bin/docker-compose

# 创建快捷方式
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

# 验证
docker-compose --version

创建docker-compose.yml文件

# 使配置生效
systemctl daemon-reload

# 重启Docker
systemctl restart docker

# 构建环境（在docker-compose.yml所在路径执行）
docker-compose up -d
