安装基础包:yum groupinstall "Development tools"

 

一、pip安装

1. 安装python

 

需要2.7版本的Python,如果centOS自带的是2.7的则不需安装(centOS7自带了2.7.5)
① 下载 python
https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
# tar xf Python-2.7.9.tar.xz
# cd Python-2.7.9
# make && make altinstall
# ln -s /usr/local/bin/python2.7 /usr/local/bin/python
④ 测试
# python -V

② 解压

③ 编译安装

# ./configure --prefix=/usr/local

 

2. 安装pip

 

首先
# yum install epel-release
然后
# yum install python-pip

 

3. 安装caravel

 

① 获得caravel源码
# wget https://github.com/airbnb/caravel/archive/master.zip
② 解压
# unzip caravel-master.zip
③ 安装
进入根目录,使用pip命令安装(考虑到境外服务器太慢,这里使用清华大学的源)
# pip install . -i https://pypi.tuna.tsinghua.edu.cn/simple/

 

 

4. 错误(如果有错误执行下面的)

 

① cffi
yum install libffi-devel
② sasl
yum install libgsasl-devel
yum install libmemcached-devel
③ python
yum install python-devel
④ openssl
yum install openssl-devel
⑤ pytz
pip install --upgrade pytz
⑥ npy_math.py
yum install numpy

yum install openssl

 

二、nmp安装

1. 安装nodejs

下载node-v4.5.0.tar.gz(官网)
解压

 

# ./configure --prefix=/usr/local
# make
# make install
# ln -s /usr/local/bin/node /usr/bin/node

 

2. 安装npm

 

根据网址下载 install.sh (https://npmjs.org/install.sh)
# sh install.sh

3. 安装express

# npm install express -g

 

4. 安装caravel(源码安装)

 

## assuming $CARAVEL_HOME as the root of the repo
# cd $CARAVEL_HOME/caravel/assets
# npm install
# npm run prod
# cd $CARAVEL_HOME
# python setup.py install

 

三、初始化运行

创建admin用户
# fabmanager create-admin --app caravel
初始化caravel元数据
# caravel db upgrade
初始化caravel默认的用户角色和权限
# caravel init
加载示例数据
# caravel load_examples
定义运行端口
# caravel runserver -p 8088
通过http://localhost:8088就可访问

 

 

 

四、连接数据源

1. postgresql
   yum install build-dep python-psycopg2
pip install psycopg2
2. mysql
    yum install MySQL-python
database pypi package SQLAlchemy URI prefix
MySQL pip install mysqlclient mysql://
Postgres pip install psycopg2 postgresql+psycopg2://
Presto pip install pyhive presto://
Oracle pip install cx_Oracle oracle://
sqlite   sqlite://
Redshift pip install sqlalchemy-redshift redshift+psycopg2://
MSSQL pip install pymssql mssql://
Impala pip install impyla impala://
SparkSQL pip install pyhive jdbc+hive://
注意如果连接数据源报错如连接mysql数据源报错 importError no moduel MySQLdb解决办法如下:

 

 

linux环境下安装MySQL-python的两种方式

 

 

第一种 简单:yum install MySQL-python

第二种:复杂:需要自己源码编译,依赖包比较多

a.   gcc

b.   setuptools

c.  python-dev

 

第二章详细步骤如下:

 

A.下载:wget http://sourceforge.net/projects/mysql-python/files/latest/download 

 

B.

 

$ tar xfz MySQL-python-1.2.3.tar.gz
$ cd MySQL-python-1.2.3

 

$whereis  mysql_config 

 

mysql_config: /usr/bin/mysql_config
$ vim site.cfg
修改mysql_config为mysql配置文件的路径 /usr/bin/mysql_config 

 

还要修改

 

 threadsafe = False
$ python setup.py build
$ sudo python setup.py install
在python环境下
>>> import MySQLdb
/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg/_mysql.pyc, but /app/MySQL-python-1.2.5 is being added to sys.path
安装成功
-------------------------------------------------------------------------------------------------------------------------------
安装过程中报,error: command 'gcc' failed with exit status 1
用yum install gcc 显示已经是安装最新版本
未安装mysql-devel包
解决方法:yum install mysql-devel
