1.安裝MySQL

useradd -s /sbin/nologin -M mysql

 tar zxvf mysql-5.5.29.tar.gz
 cd mysql-5.5.29
 cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
 -DINSTALL_DATADIR=/data/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
 -DDEFAULT_CHARSET=utf8 \
 -DDEFAULT_COLLATION=utf8_general_ci \
 -DWITH_EXTRA_CHARSETS=complex \
 -DMYSQL_USER=mysql

  make &&  make install 

Mysql 安裝之后的配置:

cd /usr/local/mysql
scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

  chown -R root .
  cp support-files/my-medium.cnf /etc/my.cnf
  vim /etc/my.cnf
 添加以下內(nèi)容:
 [mysqld]
 port            = 3306
 socket          = /tmp/mysql.sock
 basedir         = /usr/local/mysql
 datadir         = /data/mysql
 user            = mysql
 character_set_server    = utf8

配置mysql 啟動(dòng)

  cp support-files/mysql.server /etc/init.d/mysql
  vim /etc/init.d/mysql
 添加以下兩行
 basedir=/usr/local/mysql
 datadir=/data/mysql

安裝完成啟動(dòng)服務(wù)修改密碼:

  service mysql start
  添加軟連接:
  ln -s /usr/local/mysql/bin/mysql /usr/bin
  ln -s /usr/local/mysql/bin/mysqladmin /usr/bin
  初始化密碼:
  mysqladmin -uroot password

2.安裝pip

yum install -y epel-release
安裝好 EPEL 之后,還需要運(yùn)行這個(gè)命令:

yum install -y yum-utils && yum-config-manager --enable epel
來(lái)啟用 EPEL,這樣才可以運(yùn)行命令:

yum install -y python-pip
來(lái)安裝 pip 工具。最后,建議大家再運(yùn)行命令:

pip install --upgrade pip

3.安裝superset平臺(tái):

依賴(lài)包安裝;

 yum upgrade python-setuptools
 yum install gcc gcc-c++ libffi-devel python-devel python-pip python-wheel openssl-devel libsasl2-devel openldap-devel

官網(wǎng)推薦在virtualenv中安裝 superset
pip install virtualenv

創(chuàng)建和激活一個(gè) virtualenv ,創(chuàng)建后會(huì)在當(dāng)前目錄生成一個(gè) supersetenv的目錄
virtualenv supersetenv

啟動(dòng) supersetenv,先進(jìn)入創(chuàng)建的virtualenv目錄

cd supersetenv/
 source ./bin/activate

更新pip和setuptools:
pip install --upgrade setuptools pip

安裝mysqlclient。
將superset的元數(shù)據(jù)存儲(chǔ)改成mysql,就需要這一步。
ROOT權(quán)限下,為了連接mysql
yum install mysql-devel

virtualenv下:
pip install mysqlclient

添加superset的配置文件。
在python所在的目錄即PYTHONPATH(如,我這里是/root/supersetenv/bin下),手動(dòng)添加superset的配置文件superset_config.py。內(nèi)容如下:

 #-*- coding: utf-8 -*-
 #===============superset_config.py開(kāi)始================
 #使用python2.7,如果下面三行不加的話(huà),使用中文時(shí)會(huì)出問(wèn)題。
 import sys # import sys package, if not already imported
 reload(sys)
 sys.setdefaultencoding('utf-8')

 #---------------------------------------------------------
 #Superset specific config
 #---------------------------------------------------------
 ROW_LIMIT = 5000
 SUPERSET_WORKERS = 4
 SUPERSET_WEBSERVER_PORT = 8088

 #---------------------------------------------------------
 #Flask App Builder configuration
 #---------------------------------------------------------
 #Your App secret key
 SECRET_KEY = '\2\1thisismyscretkey\1\2\e\y\y\h'

 #元數(shù)據(jù)存儲(chǔ)默認(rèn)使用的是sqlite。SQLALCHEMY_DATABASE_URI = 'sqlite:////path/to/superset.db'
 #我這里改成mysql
 #mysql://用戶(hù)名:密碼@192.168.1.162/數(shù)據(jù)庫(kù)名?charset=utf8
 SQLALCHEMY_DATABASE_URI = 'mysql://datag:yjkdatag@192.168.1.162/superset?charset=utf8'

 #Flask-WTF flag for CSRF
 WTF_CSRF_ENABLED = True

 #Set this API key to enable Mapbox visualizations
 MAPBOX_API_KEY = ''

 #漢化
 BABEL_DEFAULT_LOCALE='zh'
 LANGUAGES = {
 'zh': {'flag': 'cn', 'name': 'Chinese'},
 'en': {'flag': 'us', 'name': 'English'}
 }

 #=============== superset_config.py結(jié)束===============

最后,安裝 superset,在安裝之前需要在mysql先創(chuàng)建superset的數(shù)據(jù)庫(kù)

 show variables like "%char%";
 create database superset
 use superset
 --這里如果不設(shè)置數(shù)據(jù)庫(kù)為utf8,在后面初始化數(shù)據(jù)庫(kù)時(shí)會(huì)報(bào)  Specified key was too long; max key length is 767 bytes 的錯(cuò)誤
 alter database superset character set utf8;

安裝superset,最新版本是26.3

pip install superset==0.26.3
 pip install "markdown<3.0.0" superset

創(chuàng)建admin用戶(hù)

 fabmanager create-admin --app superset
 然后需要輸入:
 Username [admin]: admin
 User first name [admin]: admin
 User last name [user]: admin
 Email [admin@fab.org]: admin@163.com
 Password: admin
 Repeat for confirmation: admin

初始化數(shù)據(jù)
superset db upgrade

啟動(dòng)superset
superset runserver
//或者指定端口

 superset runserver -p 8388 &

 pip install pymysql
