centos 7 下安装配置 caravel

时间:2016-11-03 17:13 来源:linux.it.net.cn 作者:IT

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

$ 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
