Elasticsearch 5.0 以上 elasticsearch-head 安装教程

编程学习 elasticsearch, es, node 0 Comments

elasticsearch 5.0/5.0.1以上版本的elasticsearch-head插件，使用node单独运行，会出现跨站访问的问题：

http://localhost:9200/_nodes. No 'Access-Control-Allow-Origin' 
header is present on the requested resource. 
Origin 'http://localhost:9100' is therefore not allowed access.

elasticsearch-head 安装教程如下：

1、安装node；
2、下载elasticsearch-head，安装node组件：

>git clone git://github.com/mobz/elasticsearch-head.git
>cd elasticsearch-head
>npm i
>npm i grunt-cli -g
>grunt server

3、elasticsearch.yml 增加配置项

http.cors.enabled: true
http.cors.allow-origin: /http?:\/\/127.0.0.1(:[0-9]+)?/

4、Gruntfile.js 增加hostname配置项

connect: {
         server: {
            options: {
               port: 9100,
               hostname: '*',
               base: '.',
               keepalive: true
            }
         }
      }

5、修改配置文件后各自重启

http://127.0.0.1:9100/ 访问即可(http.cors.allow-origin 里配的是127.0.0.1哦)

Docker：部署Node.js项目

编程学习 docker, node.js 0 Comments

Dockerfile:

FROM node:6.2
# Author
MAINTAINER wizzer "wizzer@qq.com"
ENV PORT 1337
RUN apt-get update && apt-get install -y \
		imagemagick \
	--no-install-recommends && rm -rf /var/lib/apt/lists/*
RUN mkdir -p /node/nodeshop
WORKDIR /node/nodeshop

RUN npm config set registry https://registry.npm.taobao.org
RUN npm i node-gyp -g
RUN npm i pm2 -g
ADD api /node/nodeshop/api
ADD assets /node/nodeshop/assets
ADD config /node/nodeshop/config
ADD tasks /node/nodeshop/tasks
ADD views /node/nodeshop/views
ADD app.js /node/nodeshop
ADD Gruntfile.js /node/nodeshop
ADD package.json /node/nodeshop
RUN npm i
EXPOSE ${PORT}
ENV LANG C.UTF-8
ENV TZ "Asia/Shanghai"
VOLUME ["/node/nodeshop/cert", "/node/nodeshop/upload", "/node/nodeshop/backup"]
CMD [ "pm2", "start", "--no-daemon", "app.js" ]

docker-compose.yml:

redis:
  image: redis
db:
  image: mariadb:5.5
  environment:
    "MYSQL_ROOT_PASSWORD": "xxxxxx"
    "MYSQL_DATABASE": "db123"
  command: "mysqld --character-set-server=utf8"
  ports:
    - "127.0.0.1:3306:3306"
  volumes:
    - "/node/nodeshop/db:/var/lib/mysql"
web:
  image: wizzer/nodeshop
  links:
    - redis
    - db
  environment:
    "MYSQL_HOST": "db"
    "MYSQL_USER": "root"
    "MYSQL_PASSWORD": "xxxxxx"
    "MYSQL_DATABASE": "db123"
    "MYSQL_LIMIT": 150
    "REDIS_HOST": "redis"
    "REDIS_PASS": ""
    "LOG_LEVEL": "verbose"
    "PORT": 1337
    "NODE_ENV": "development"
  command: "pm2 start /node/nodeshop/app.js --no-daemon"
  ports:
    - "1337:1337"
  volumes:
    - "/node/nodeshop/cert:/node/nodeshop/cert"
    - "/node/nodeshop/upload:/node/nodeshop/upload"
    - "/node/nodeshop/backup:/node/nodeshop/backup"

说明：
1、把数据库端口3306映射到127.0.0.1:3306 是为了还原数据库,web映射端口不绑定IP这样外网可以访问,通过nginx代理出去.
2、volumes将数据文件、数据库文件使用容器外文件夹，这样重启后不丢失数据.

…

1、打包最新image
docker build -t wizzer/nodeshop .

. 为当前文件夹,通过Dockerfile打包
wizzer/nodeshop:v1.0 用户名/项目:版本号

docker images 列出所有镜像
docker rmi ID 删除某个镜像
docker ps -a 列出所有容器
docker rm ID 删除某个容器
2、Centos安装Docker-engine 1.7.1版本(windows安装docker-toolbox即可)

vi /etc/yum.repos.d/docker.repo

[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/6/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg

yum search docker
yum install docker-engine.x86_64
service docker start 启动docker服务
chkconfig docker on 设置为开启启动

3、Centos安装docker-compose 1.1.0版本(windows安装docker-toolbox即可)

curl -L https://github.com/docker/compose/releases/download/1.7.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

ps：第一行命令复制会少符号，到 https://github.com/docker/compose/releases/ 复制命令。

4、迁移镜像
docker ps -a 列出容器快照
docker export ID > nodeshop.tar 将容器快照导出
cat /node/nodeshop.tar | docker import – wizzer/nodeshop 加载容器快照

5、创建运行目录
分别创建4个文件夹【必须】
/node/nodeshop/cert 将证书文件拷贝进去
/node/nodeshop/upload 附件上传文件夹
/node/nodeshop/backup 数据库备份文件夹
/node/nodeshop/db 数据库文件夹
将Dockfile 、 docker-compose.yml 拷贝到 /node/nodeshop 目录

6、启动项目

cd /node/nodeshop
docker-compose up -d

docker-compose ps 列出正在运行的服务
docker-compose stop 停止服务
docker ps -a 列出所有容器状态
docker rm ID 删除容器

若要修改环境变量，可以修改 /node/nodeshop/docker-compose.yml 文件内容

7、安装mariadb客户端（用于连接数据库）

cd /etc/yum.repos.d/
vi MariaDB.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

yum install MariaDB-client

MariaDB-server 不需要安装

8、还原数据

mysql -h 127.0.0.1 -u root -p
密码
show databases;
use nodeshop;
source /node/nodeshop/db.sql;
show tables;
exit;

9、重启docker容器

docker-compose stop
docker-compose start

10、进入容器执行命令，比如测试网络情况

docker ps -a
docler exec -it ID /bin/bash
ping 192.168.1.11
exit

如果网络不通，可能需要关闭防火墙，然后重启docker服务：

service docker restart

11、容器开机自启动

vi /etc/rc.d/rc.local
/usr/local/bin/docker-compose -f /node/sunshop/docker-compose.yml up -d

注意：如果是centos7 则需要执行 chmod +x /etc/rc.d/rc.local 添加执行权限.

本教程适用于Centos6.x版本，7或有不同。
