Ubuntu服务器部署

1. 开发环境配置

1.1 Python/Python3安装

python3 install

ubuntu14.04 升级python3.4到3.6
Ubuntu 16.04 安装 python3.6 环境并设置为默认

# 1. 更新系统包
sudo apt-get update
sudo apt-get upgrade
# 2. 安装Pip
//sudo apt-get install python-pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py
# 3. 检查 pip 是否安装成功
pip -V
# python3 pip 升级命令
pip3 install --upgrade pip

pip version >= 10
ImportError: cannot import name ‘main‘

cd /usr/bin
sudo vi pip
```

### 1.2 Git Repository for Ubuntu
##### git install
```shell
sudo apt-get install git
git --version

create the repository directory for git

mkdir projectGitlab/
```     
##### git configure and ssh key generate

```shell
git config -- global user.name "winkyqin"
git config -- global user.email "winkyqin@163.com"
git config -- list
# ssh key generate
ssh-keygen -t rsa -C "winkyqin@163.com"
# into the directory .ssh/ to get ssh key detail
# get the ssh key string detail
ls ~ .ssh
cat id_rsa.pub  
# copy the ssh key to paste
```  
     
#####  git repository clone
```shell     
git clone “xxx.git”

1.3 ubuntu安装常用数据库（mongoDB, mysql）

1.3.1 mysql for ubuntu

sudo apt-get install mysql-server

sudo apt-get install mysql-client

sudo apt-get install libmysqlclient-dev

sudo netstat -tap | grep mysql

msyql -u root -p

show database 

show tables

mysql数据库使用root账号创建新用户

    # -- 创建用户设置
    create user 'chaininfo_dev'@'%' identified by 'chaininfo_dev';
    # -- 创建数据库
    create database database_chain_news DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
    # -- 为用户赋权限
    grant all privileges on database_chain_news.* to 'chaininfo_dev'@'%' identified by 'chaininfo_dev';
    grant all privileges on database_chain_news.* to 'chaininfo_dev'@'localhost' identified by 'chaininfo_dev';
    flush privileges;

1.3.2 mongodb for ubuntu install

sudo apt-get install mongodb

(install no response input before the line above :
  
    sudo apt-get update
)

    # check the mongodb is start or not  
    gprep mongo -l
    
    # where the directory is the mongo location 
    locate mongo
    
    # mongodb uninstall 
    sudo apt-get --purge remove mongodb mongodb-clients mongodb-server

mongodb start and stop

 # start
 sudo systemctl start mongodb       
 # stop 
 sudo systemctl stop mongodb

mongodb install error
- Failed to start mongod.service: Unit not found
  
  …
- Failed global initialization: BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly.
（全球初始化失败:BadValue无效或没有用户语言环境设置。请确保LANG and/or LC_ 正确设置环境变量）*

解决方法
方法一：手动设置变量，只是临时有用，重启后就没用了，需要在环境变量配置文件添加一行。
```
 sudo vim /etc/profile
 export LC_ALL=C
```

方法二：手动更改源环境

 sudo vim /etc/default/locale
 LANG="en_US.UTF-8"
 LANGUAGE="en_US:en"
 LC_ALL="en_US.UTF-8"

1.4 Scrapy install

#dependency lib
sudo apt-get install libssl-dev
pip install pyopenssl --upgrade
#or
pip3 install pyopenssl --upgrade

#install scrapy 
pip install scrapy
#or
