CentOS7 部署 catalyst 框架步骤

由于需要将catalyst框架部署到Linux（CentOS7.0）服务器 ，所以这里记录相关的部署步骤，以备后用。

一、安装Anaconda

1、下载 Anaconda(python3.6 catalyst官方推荐)

各版本镜像包：https://repo.anaconda.com/arc...

python3.6的对应的是 Anaconda 5.2，5.3以后的都是python 3.7的不要看错了，这里我们要安装 python 3.6, 如果安装python3.7 版本，在环境中安装 catalyst 框架会失败。

下载命令：

wget --no-check-certificate  https://repo.anaconda.com/archive/Anaconda3-5.2.0-Linux-x86_64.sh

2、更改为可执行权限

chmod +x Anaconda3-5.2.0-Linux-x86_64.sh

3、执行脚本

./Anaconda3-5.2.0-Linux-x86_64.sh 2>&1 | tee conda-all.log

如果在安装的时候报这样的错bunzip2: command not found,则执行下边的命令安装：

yum install -y bzip2

4、安装记录
by running conda init ?是否初始化，我们选 yes

[/root/anaconda3] >>> 
PREFIX=/root/anaconda3
installing: python-3.6.5-hc3d631a_2 ...
Python 3.6.5 :: Anaconda, Inc.
installing: blas-1.0-mkl ...

by running conda init? [yes|no]
[no] >>> yes
no change     /root/anaconda3/condabin/conda
no change     /root/anaconda3/bin/conda
no change     /root/anaconda3/bin/conda-env
no change     /root/anaconda3/bin/activate
no change     /root/anaconda3/bin/deactivate
no change     /root/anaconda3/etc/profile.d/conda.sh
no change     /root/anaconda3/etc/fish/conf.d/conda.fish
no change     /root/anaconda3/shell/condabin/Conda.psm1
no change     /root/anaconda3/shell/condabin/conda-hook.ps1
no change     /root/anaconda3/lib/python3.7/site-packages/xontrib/conda.xsh
no change     /root/anaconda3/etc/profile.d/conda.csh
modified      /root/.bashrc

installing: anaconda-5.2.0-py36_3 ...
installation finished.
Do you wish the installer to prepend the Anaconda3 install location
to PATH in your /root/.bashrc ? [yes|no]
[no] >>> yes

Appending source /root/anaconda3/bin/activate to /root/.bashrc
A backup will be made to: /root/.bashrc-anaconda3.bak

For this change to become active, you have to open a new terminal.

Thank you for installing Anaconda3!

我们可以看到在安装的时候，已经将bin目录加入到了环境变量PATH：

php3.7版本：

[root@vultr software_sources]# cat ~/.bashrc
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/root/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/root/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/root/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/root/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

php3.6版本：

[root@vultr software_sources]# cat ~/.bashrc
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi



# added by Anaconda3 installer
export PATH="/root/anaconda3/bin:$PATH"

重新加载 bashrc 立即生效：

# 将anaconda的bin目录加入PATH，根据版本不同，也可能是~/anaconda3/bin
# echo 'export PATH="/root/anaconda3/bin:$PATH"' >> ~/.bashrc # 如果.bashrc没有路径则需要执行该命令

# 更新bashrc以立即生效()
source ~/.bashrc  #Anaconda 5.2不需要执行此命令，Anaconda 5.2以上需要

5、测试

 [root@vultr software]# conda -V
conda 4.5.4

可以看到conda已经安装ok。

6、卸载（参考）
如果conda安装错版本，则需要卸载重装,也非常简单，直接在根目录移除即可

rm -rf  ~/anaconda3

删掉环境变量的conda路径：

vim ~/.bashrc

二、安装Catalyst

Catalyst框架官方文档：https://enigma.co/catalyst/in...

1、下载 python3.6-environment.yml 文件到本地

# 地址
https://github.com/enigmampc/catalyst/blob/master/etc/python3.6-environment.yml

或者直接复制 python3.6-environment.yml 文件内容 到本地：

2、使用conda创建单独环境

conda env create -f python3.6-environment.yml
source activate catalyst

在安装时可能系统会缺少某些必要的包，这是我在CentOS7.0安装时缺少必要的包：

# g++
yum install gcc-c++

安装完成后：

#
# To activate this environment, use:
# > source activate catalyst
#
# To deactivate an active environment, use:
# > source deactivate

3、激活环境测试

[root@vultr catalyst_env]#  source activate catalyst
(catalyst) [root@vultr catalyst_env]# catalyst ingest-exchange -x binance -i btc_usdt -f daily
Trying to ingest exchange bundle binance...
    [====================================]  Ingesting daily price data on binance:  100%
(catalyst) [root@vultr catalyst_env]#
